Murray, Luke. "Jesuit Hebrew Studies After Trent: Cornelius a Lapide (1567–1637)." Journal of Jesuit Studies 4, no. 1 (November 30, 2017): 76–97. http://dx.doi.org/10.1163/22141332-00401004.
Full textAbstract:
This essays studies the biblical hermeneutics of Cornelius a Lapide, focusing on his knowledge of Hebrew. After reviewing a post-Tridentine bias against Catholic biblical studies, the essay is divided in three parts. The first part is a brief introduction to a Lapide’s life; the second part addresses his position on the Vulgate and its relationship to the original languages of scripture; and the third part presents key passages from a Lapide on the Hebrew language, drawn from his biblical commentaries. In the end, I argue that regardless of a Lapide’s imperfect knowledge of Hebrew, he still shows that Catholic scholars could engage in a close study of scripture’s original languages after Trent’s decree on the Vulgate, and could incorporate works from across confessional boundaries.

Full textAbstract:
This paper presents an automatic recognition system for classifying stones belonging to different Calabrian quarries (Southern Italy). The tool for stone recognition has been developed in the SILPI project (acronym of “Sistema per l’Identificazione di Lapidei Per Immagini”), financed by POR Calabria FESR-FSE 2014-2020. Our study is based on the Convolutional Neural Network (CNNs) that is used in literature for many different tasks such as speech recognition, neural language processing, bioinformatics, image classification and much more. In particular, we propose a two-stage hybrid approach based on the use of a model of Deep Learning (DL), in our case the CNN, in the first stage and a model of Machine Learning (ML) in the second one. In this work, we discuss a possible solution to stones classification which uses a CNN for the feature extraction phase and the Softmax or Multinomial Logistic Regression (MLR), Support Vector Machine (SVM), k-Nearest Neighbors (kNN), Random Forest (RF) and Gaussian Naive Bayes (GNB) ML techniques in order to perform the classification phase basing our study on the approach called Transfer Learning (TL). We show the image acquisition process in order to collect adequate information for creating an opportune database of the stone typologies present in the Calabrian quarries, also performing the identification of quarries in the considered region. Finally, we show a comparison of different DL and ML combinations in our Two-Stage Hybrid Model solution.

Full textAbstract:
La lapine peut être fécondée aussitôt après la mise bas ou tout au long de la lactation, et être simultanément gravide et allaitante. Néanmoins, la réceptivité des femelles est variable au cours de la lactation : elle est maximale aussitôt après la mise bas (proche de 100 %) et minimale 3-5 jours après (40-65 %). Bien que les résultats expérimentaux concernant les effets de la lactation sur le taux d’ovulation et la mortalité embryonnaire soient parfois contradictoires, la fertilité et la prolificité des lapines allaitantes sont globalement plus faibles que celles des lapines non allaitantes. En effet, la lactation a, d’une manière générale, un effet négatif sur le pourcentage de femelles ovulant (-26 %), le taux de gestation (-33 %), et la viabilité foetale (-10 %). De plus, la lactation entraîne une diminution de la croissance pondérale des foetus (-20 %). L’hyperprolactinémie et la faible progestéronémie chez les lapines simultanément gravides et allaitantes, ainsi que le déficit nutritionnel engendré par la production laitière, semblent être les principaux facteurs responsables des effets observés.

En France, l’élevage cunicole conventionnel est réalisé en système hors-sol (environ 700 éleveurs). La cuniculture alternative avec accès des lapins à l'extérieur, est essentiellement sous certification « Agriculture Biologique » (AB) reste marginale (environ 50 cuniculteurs) et ne produit pas suffisamment pour répondre à la demande des consommateurs. Nous faisons ici la synthèse des connaissances sur le fonctionnement et les performances des systèmes cunicoles AB ou au pâturage. Le lapin étant un animal herbivore, la cuniculture AB privilégie le pâturage, et bien maîtrisée elle peut rémunérer un demi SMIC avec 40 lapines reproductrices sur 4 ha (pâtures et cultures complémentaires). Pour les porteurs de projet, outre l'accès à la terre, la gestion de la prophylaxie et de l'alimentation sont deux contraintes fortes des systèmes cunicoles AB. Le nouveau règlement Européen, applicable depuis janvier 2022, préconise l'utilisation maximale du pâturage mais, de façon contradictoire, permet d'installer un troupeau de 40 lapines sur seulement 200 m² de pâturage et n'oblige pas à une rotation des parcs entre deux groupes d'animaux, ce qui élève le risque de parasitisme. Les récentes études ont quantifié l’ingestion d'herbe (30 à 80 g MS/jour/lapin) et la croissance du lapin au pâturage (15 à 25 g/jour). Le cycle productif d'un atelier cunicole AB est extensif avec une moyenne de 2,7 mise bas par lapine et par an (contre 6,7 en système hors sol). Une application smartphone d'assistance à la conduite d'élevage (GAELA) a été récemment développée pour construire un référentiel de performances permettant de soutenir le développement de la cuniculture AB ou au pâturage.

Full textAbstract:
Kakanui volcaniclastic deposits on the South Island of New Zealand are the remnants of two late Eocene to early Oligocene Surtseyan-type cones. Eruptive-dominated material of the (i) stratified tuff and lapilli tuff, and (ii) lapilli tuff breccia lithofacies and post-eruptive debris of the (iii) shell-rich tuff and lapilli tuff, and (iv) chaotic and cross-bedded tuff and lapilli tuff lithofacies compose the deposits. The 9–250 m thick stratified tuff and lapilli tuff contains grain-flow deposits originating from low-volume tephra jets and local thinning and fining upward sequences that formed from density currents during sustained uprush. The lapilli tuff breccia, up to 4.5 m thick, contains inward-dipping beds deposited via debris flows along inner-cone walls. Burrows and articulated shells in the 2–4 m thick shell-rich tuff and lapilli tuff indicate volcanic quiescence and low sedimentation rates, whereas shell fragments upsection signal increased wave and current activity. Burrows, pyrite concretions, and mudstone in the lower part of the 26 m thick chaotic tuff and lapilli tuff indicate suspension deposition and cessation in pyroclastic volcanism. High-angle trough cross-beds and limestone rip-up fragments upsection are consistent with wave-induced current reworking. The depositional model involves a Surtseyan-type eruption on a continental shelf, followed by colonization of organisms on the tops of planed-off cones. The Kakanui deposits comprise a cluster of cones constituting part of a late Eocene – early Oligocene monogenetic volcanic field. The Kakanui succession provides an opportunity to study deposits that form from explosive subaqueous pyroclastic eruptions and wave-dominated deposition and erosion.

Full textAbstract:
Background: Minimally invasive (MIS) bunion surgery has become increasingly popular. Although early reports on outcomes have been encouraging, no study to date has compared outcomes from the MIS chevron and Akin procedures to the modified Lapidus procedure. Our primary aim was to compare early radiographic outcomes of the MIS chevron and Akin osteotomies to those of the modified Lapidus procedure in patients with comparable deformities, and secondarily to compare clinical outcomes. Methods: Patients were retrospectively reviewed for inclusion from a prospectively collected foot and ankle registry. Patients were eligible if they underwent either the MIS bunionectomy or modified Lapidus procedure and had preoperative and minimum 5-month postoperative weightbearing radiographs. Forty-one patients who underwent MIS bunionectomy were matched to 41 patients who underwent Lapidus bunionectomy based on radiographic parameters. Demographics, radiographic parameters, complications, reoperations, and PROMIS scores were compared between groups. Results: Both groups achieved similar radiographic correction. There was no significant difference in pre- or postoperative PROMIS scores between groups. Procedure duration was significantly faster in the MIS group ( P < .001). Bunion recurrence (hallux valgus angle ≥20 degrees) occurred in 1 MIS patient and 2 Lapidus patients, with all patients asymptomatic. The most common reason for reoperation was removal of hardware (4 patients in the MIS group, 2 patients in the Lapidus group). Conclusion: This is the first study to our knowledge to compare early radiographic outcomes between MIS bunionectomy and the modified Lapidus procedure in patients matched for bunion severity. We found that patients with similar preoperative deformities experience similar radiographic correction following MIS chevron and Akin osteotomies vs modified Lapidus bunionectomy. Further research is needed to investigate satisfaction differences between the procedures, longer-term outcomes, and which deformities are best suited to each procedure. Level of Evidence: Level III, Retrospective case control study.

Full textAbstract:
Background: Shortening and dorsiflexion of the first metatarsal are known potential side effects of metatarsal osteotomies for hallux valgus (HV) with the potential to cause transfer metatarsalgia. We compared the effect of the first tarsometatarsal joint arthrodesis (Lapidus procedure), proximal lateral closing wedge osteotomy (PLCWO), and intermetatarsal suture button fixation procedures on the length and dorsiflexion of the first ray. Methods: We retrospectively evaluated 105 feet in 99 patients with 30 weeks of follow-up. The average age was 54 years. Seventy-four feet had a Lapidus procedure, 12 had a PLCWO, and 19 had intermetatarsal suture button fixation. Digital radiographic measurements were made for the pre- and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), absolute and relative shortening of the first ray, and dorsiflexion. Results: Preoperative HVA and IMA did not differ between treatment groups ( P > .05 for each). Similar corrections of HVA (30.5-13.5 degrees) were achieved between all groups ( P > .05). The IMA was improved more in the Lapidus group (14.3-6.5 degrees) compared with the suture button fixation group (14.2-8.1 degrees) ( P = .045). There were significant differences in the change in absolute first cuneiform–metatarsal length (FCML) between the Lapidus (–1.6 mm), PLCWO (–2.3 mm), and intermetatarsal suture button fixation (+1.9 mm) procedure ( P = .004). There were also significant differences in relative first metatarsal shortening between the Lapidus (0.1 mm relative shortening), PLCWO (1.1 mm relative shortening), and intermetatarsal suture button fixation (1.3 mm lengthening) procedure ( P < .001). The average dorsiflexion differed between the Lapidus (1.8 degrees) and suture button fixation (0.4 degrees) groups ( P = .004). Conclusion: Intermetatarsal suture button fixation relatively lengthened the first ray, the Lapidus procedure maintained length, and the PLCWO relatively and absolutely shortened it. Dorsiflexion may be higher with the Lapidus and osteotomy procedures. Level of Evidence: Level III, retrospective comparative series.

Full textAbstract:
Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Minimally invasive bunion surgery is relatively new in the United States, with the requisite burrs only approved for use by the FDA in 2017. Early reports on outcomes have been encouraging. However, no study to date has compared outcomes from the minimally invasive chevron and Akin procedures (MICA) to the modified Lapidus procedure. Our goal was to compare clinical and radiographic outcomes of MICA to those of the modified Lapidus procedure in patients with comparable deformities. We hypothesized that radiographic parameters of hallux valgus would be superior in the Lapidus group, but that there would be no significant difference in clinical outcomes or satisfaction between the two groups. Methods: Patients were retrospectively reviewed for inclusion from a prospectively-collected foot and ankle registry at our institution. Patients were eligible if they underwent either the MICA or modified Lapidus procedure, were 18 years or older, and had preoperative and minimum 5 month postoperative weightbearing radiographs. Exclusion criteria included prior forefoot surgery, additional surgeries (such as metatarsal shortening), and concomitant foot conditions (such as flatfoot deformity). Each surgery was performed by one of six fellowship-trained orthopedic foot and ankle surgeons. Demographics, PROMIS scores, and satisfaction data were collected from the registry. Complications and reoperations were collected from chart review. The hallux valgus angle (HVA), intermetatarsal angle (IMA), and tibial sesamoid position (SP) were measured pre- and postoperatively. Patients in the MICA group were matched to patients who underwent Lapidus bunionectomy based on radiographic parameters. Differences between the groups were assessed with paired t-tests for continuous variables and chi-square tests for categorical variables. Results: 41 patients who underwent MICA and 81 patients who underwent Lapidus bunionectomy met the inclusion criteria. Of the Lapidus patients, 41 were included, matched to the MICA patients. There were no significant differences in demographics or preoperative parameters between groups aside from sex (Table). Both groups achieved similar radiographic correction (Table). Bunion recurrence (HVA >=20°) occurred in one MICA patient and two Lapidus patients, with all patients asymptomatic. The most common reason for reoperation was removal of hardware (4 patients in the MICA group, 2 patients in the Lapidus group). One additional patient in the MICA group required reoperation for wound closure, and one additional patient in the Lapidus group required a derotational proximal phalanx osteotomy. Conclusion: This is the first study to our knowledge to compare outcomes between MICA and the modified Lapidus procedure in patients matched for bunion severity. We found that patients with similar preoperative deformities experience similar radiographic outcomes following MICA versus modified Lapidus bunionectomy. Our analysis of PROMIS scores and satisfaction data is currently underway. Although this is short-term data, it provides additional support for minimally invasive techniques which allow for faster, less painful recoveries. Further research is needed to investigate longer term outcomes and to establish which deformities are best suited to each procedure.

Full textAbstract:
Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Lapidus procedure and Scarf osteotomy are indicated for treatment of mild to moderate hallux valgus. Advantages of modified Lapidus procedure include ability to address severe deformity, first tarsometatarsal arthritis, and first ray hypermobility. Advantages of Scarf osteotomy include greater correction of the distal metatarsal articular angle (DMAA) and greater fixation stability than other techniques. Both procedures have shown good radiographic and clinical outcomes; however, no prior studies have compared these outcomes between the procedures. The aim of this study was to compare clinical and radiographic outcomes between patients with hallux valgus treated with the modified Lapidus procedure or Scarf osteotomy. Methods: This retrospective cohort study included patients treated by one of seven fellowship-trained foot and ankle surgeons were identified. Inclusion criteria were age greater than 18 years, primary modified Lapidus procedure or Scarf osteotomy for hallux valgus, minimum 1-year postoperative PROMIS scores, and minimum 3-month postoperative radiographs. Revision cases were excluded. Clinical outcomes were assessed using six PROMIS domains: Pain Interference, Pain Intensity, Physical Function, Global Mental Health, Global Physical Health, and Depression. Pre- and postoperative radiographic parameters were measured on AP (HVA, IMA, DMAA, tibial sesamoid position), and lateral (talo-1st-metatarsal angle (Meary’s), Horton index, Seiberg index, sagittal IMA) x-rays. Statistical analysis utilized targeted maximum likelihood estimation controls for confounding of bunion severity by including covariates for baseline HVA and IMA. Statistics were also analyzed in a restricted cohort of mild to moderate severity bunions (HVA<40 and IMA<16; n=57 each). Complications including repeat surgeries, recurrence of deformity, and malunion/nonunion were recorded. Results: 136 patients (73 Lapidus, 63 Scarf) with average 17.8 month follow-up constituted our study. Both groups demonstrated significant improvement in Global Physical Health, Global Mental Health, and Physical Function, with patients in the Lapidus group showing a significantly greater improvement of 3.6 points (p=0.01) compared to Scarf. After controlling for bunion severity, the probability of having normal postoperative IMA (<10 ) was 17% lower (p<0.001) with Scarf compared to Lapidus. This finding was consistent in the restricted cohort of mild to moderate severity bunions. Lapidus group demonstrated significantly greater correction in Meary’s angle, Seiberg index, and sagittal IMA. Complications in the Lapidus group included one nonunion, three symptomatic implants, two hallux varus. The Scarf group had one reoperative cheilectomy and one second metatarsal stress fracture. Conclusion: This is the first study to compare both radiographic and patient-reported outcomes between Lapidus procedure and Scarf osteotomy for correction of hallux valgus deformity. While both procedures yielded improvements in outcomes, results suggest that the probability of having a normal postoperative IMA is greater with Lapidus procedure, even when adjusted for severity of deformity. In addition, greater correction reflected in sagittal measurements may further support the role of rotational correction in the Lapidus procedure. [Table: see text]

Full textAbstract:
Category: Bunion Introduction/Purpose: A 6-8 week non-weightbearing period post modified lapidus arthrodesis has traditionally been universally accepted. A review of the literature reports nonunion rates between 5-33% after modified lapidus with 6-8 weeks of non- weightbearing. There are only a few reports in the literature that discuss immediate weightbearing after the modified lapidus procedure. In this retrospective review, we examine the nonunion rate among patients undergoing the modified lapidus arthrodesis who were immediately weightbearing in a controlled ankle motion (CAM) boot. It is our hypothesis that the non- union rate will be comparable to the traditional post-operative protocol nonunion rate. Methods: In this retrospective study, we evaluated chart data on patients who underwent a modified Lapidus arthrodesis with immediate weight- bearing in a CAM boot. The goal of the study was to determine if a modified Lapidus surgical technique in conjunction with rigid internal fixation produces the necessary stability post-operatively in order to allow bony consolidation while being stressed with immediate weight bearing forces. Patients who underwent a modified Lapidus arthrodesis using either a 3 screw construct or a medially placed locking plate with an interfragmentary screw were included in the study. Patients with other adjunctive procedures that would prevent early weight bearing were not included in the investigation. Results: A total of 376 patients were identified with 74 patients meeting inclusion criteria. 4 patients had bilateral procedures performed at separate times for a total of 78 Lapidus procedures. 31 patients had a 3 screw construct while 43 patients had a medial locking plate with an interfragmentary screw. 15 patients admitted to using nicotine. Additionally, 7 patients had type II Diabetes Mellitus. Autogenous shear- strain relief bone graft was used in 75 of the 79 procedures.Three patients (3.8%) experienced a post-operative non-union. Interestingly, none of the patients with non-unions were smokers and only one patient was diabetic. Conclusion: The results of this study found a 3.8% nonunion rate. Based on these results we conclude that a modified Lapidus procedure using a long, solid interfragmentary screw with either additional screw support or a locking plate, we may permit patients to ambulate safely in a CAM boot immediately post- operative period without affecting surgical outcome.

Category: Bunion; Lesser Toes; Midfoot/Forefoot Introduction/Purpose: Shortening and dorsiflexion of the first metatarsal are a known side effect of metatarsal osteotomies for hallux valgus (HV) deformity with the potential to cause transfer metatarsalgia. We compared the effect of the first tarsometatarsal joint arthrodesis (Lapidus), proximal lateral closing wedge osteotomy (PLCWO), and intermetatarsal suture button fixation procedures on the length and dorsiflexion of the first ray. Methods: We retrospectively evaluated 123 feet in 115 patients. The average age was 54. There were 106 females. Eighty-four feet had a Lapidus procedure, 14 had a PLCWO, and 24 had intermetatarsal suture button fixation. Digital radiographic measurements were made for pre- and postoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), absolute and relative shortening of the first ray, and dorsiflexion. Results: Preoperative HVA and IMA did not differ between treatment groups (p>0.05 for each). Similar corrections of HVA (30.1 to 12.3 degrees) and IMA (14.7 to 7.0 degrees) were achieved in all three groups (p>0.05). There were significant differences in absolute first-cuneiform-metatarsal length (FCML) between Lapidus (-1.5mm), PLCWO (-2.5mm), and intermetatarsal suture button fixation (+1.1mm) (p<0.05). There were also significant differences in relative 1st metatarsal shortening between Lapidus (0.32mm relative lengthening), PLCWO (1.05mm relative shortening), and intermetatarsal suture button fixation (1.24mm lengthening) (p<0.05). Average dorsiflexion differed between the Lapidus (1.95 degrees) and PLCWO groups (0.49 degrees) (p<0.05). Conclusion: The use of the intermetatarsal suture button fixation relatively lengthens the first ray, whereas the Lapidus and PLCWO shorten it. Dorsiflexion may be higher with Lapidus and osteotomy procedures. These findings may be helpful to explain postoperative symptoms of metatarsalgia and for the surgeon’s selection of the appropriate surgical technique for preoperative planning. [Table: see text]

Full textAbstract:
AbstractA group of carbonate-rich tuffs are described from the Murumuli crater, Katwe-Kikorongo volcanic field, SW Uganda which contain abundant carbonatite pelletal lapilli, together with melilitite lapilli and a range of xenocrysts and lithic fragments including clinopyroxenites considered to be of mantle origin. The carbonatite lapilli consist essentially of Sr-bearing calcite and Mg-calcite which form quench-textured laths. The lapilli contain microphenocrysts of Ti-magnetite, perovskite, apatite, clinopyroxene, sanidine and altered prisms of melilite. A 7 cm long dolomite carbonatite bomb is described which displays a form typically assumed by lava clots erupted in a molten state. Chemical analyses of a tuff, the bomb and a range of minerals are presented. Carbonatite clearly played an important role in the Katwe-Kikorongo magmatism and it is suggested that carbonatite magma evolved from carbonate-bearing melilitite.

Lapidus and Pearse proved recently an interesting formula about the volume of tubular neighborhoods of fractal sprays, including the self-similar fractals. We consider the graph-directed fractals in the sense of graph self-similarity of Mauldin-Williams within this framework of Lapidus-Pearse. Extending the notion of complex dimensions to the graph-directed fractals we compute the volumes of tubular neighborhoods of their associated tilings and give a simplified and pointwise proof of a version of Lapidus-Pearse formula, which can be applied to both self-similar and graph-directed fractals.

Full textAbstract:
The energy-loss effect of the projectile for direct inner-shell ionization cross sections by charged-particle impact has been examined. The relativistic and nonrelativistic calculations for K-shell ionization with and without the energy-loss effect are made in the plane-wave Born approximation and compared with the Brandt-Lapicki theory for the corrections of the relativistic and energy-loss effect. It is demonstrated that the Brandt-Lapicki method gives a good approximation to both relativistic and nonrelativistic cross sections, which implicitly take into account the energy-loss effect. However, the use of the Brandt-Lapicki relativistic correction method in the nonrelativistic theory with the exact integration limits for energy and momentum transfer overestimates the relativistic calculations for low-energy projectiles. This indicates that the Brandt-Lapicki method for correction of the electronic relativistic effect should be used only with their energy-loss correction method.

Full textAbstract:
Volcanic belts developed along the southeastern continental margin of Laurentia between 1.70 and 1.30 Ga and subsequently metamorphosed at high grade are today largely concealed among gneiss complexes of the Grenville Province. At the eastern end of the Wakeham Group and in the La Romaine Supracrustal Belt to the east, four 1.50 Ga volcanic centres were found among gneissic synvolcanic intrusions typical of the 1.521.46 Ga Pinwarian continental magmatic arc. Upper amphibolite- to granulite-facies rhyolitic to dacitic lavas and coarse lapillistone overlie or are intimately associated with arenites typical of the Wakeham Group. Garnetite, ironstone, carbonate rock, calc-silicate rock, and sillimanite-bearing nodules, veins, and gneiss, locally preserving lapilli, are also present. The distribution, paragenesis, and modes of most of these latter units differ from those of normal metasediments but are diagnostic of metamorphosed exhalites and hydrothermal alteration zones. In the La Romaine Supracrustal Belt, they are associated with pyroclastic horizons and a mineralized composite amphibolite unit. Volcanic textures include flow banding, wispy lapilli moulding fragmented lapilli and rounded lapilli with quartz-feldspar mosaics (filled vesicles), and in situ shattering of lapilli. These textures and the presence of advanced argillic alteration point to vesicular volcanism and hydrothermal activity in a subaerial to shallow submarine environment. Rare mafic lapilli attest to coeval mafic magmatism. The pervasive calc-alkaline signature of the eruptive and intrusive felsic to mafic rocks and their distribution are compatible with the development of 1.50 Ga intra-arc volcano-sedimentary belts stemming from the Wakeham Group basin and extending eastward within the Pinwarian continental magmatic arc.

Full textAbstract:
The release of hatchery-reared fish fry for restocking is important for the enrichment of fishery resources; however, the effective evaluation of the success rate of marking such fish is challenging. We exposed juvenile crucian carp (Carassius carassius) to a single concentration of SrCl2·6H2O for 5 d and evaluated the efficiency of Sr marking of the fish otoliths (sagittae, asterisci, and lapilli) using an electron probe micro-analyzer. Sr marking signatures formed a peak in all otolith types, with a marking success rate of 100%. The ratio of Sr to Ca in the lapilli and sagittae was higher than that in the asterisci. It took 2 d from the beginning of immersion to the deposition of Sr on the lapilli and sagittae, and the time delay for asterisci was 1 d. For the lapilli and sagittae, it took 16 d to terminate Sr marking and fully recover to the pre-marking Sr level, whereas it was 12 d for the asterisci. The application of the Sr dose had no effect on the survival or growth of the carp. This study demonstrated that the lapilli are the most suitable otolith type for Sr marking observations in crucian carp and provides a theoretical basis and technical support for carp restocking using the Sr marking approach.

Full textAbstract:
Category: Bunion Introduction/Purpose: Hallux valgus (HV) is one of the most common deformities of the foot resulting in pain and lifestyle modification of the patient. Recurrence rates of 10-47% have been documented in single individual osteotomy series. Unfortunately, surgical correction and recurrence are often defined as changes related to normal radiographs and not actually as the magnitude of correction lost with follow-up. Currently there have not been studies evaluating the percentage of recurrence of intermetatarsal angle (IMA) and hallux valgus angle (HVA). As there is substantial difference in starting IMA and HVA, as well as amount of surgical correction, our goal was to evaluate the percentage loss of correction over time comparing preoperative, initial postoperative and minimum of 2-year follow up radiographs among three different surgical correction techniques. Methods: This is a retrospective chart review study that examines the weight-bearing radiographic measurements of patients undergoing hallux valgus corrective surgery at a single institution over 5 years. Fifty-three patients were divided into first tarsometatarsal arthrodesis (i.e. Lapidus), mid-diaphyseal osteotomies (i.e. scarf), and distal metatarsal osteotomies (i.e. chevron). The preoperative, initial postoperative, and final follow up weight-bearing radiographs were measured for intermetatarsal angle (IMA) and hallux valgus angle (HVA). Primary outcome was percentage of recurrence of IMA and HVA, with the difference in angles between preoperative and initial postoperative weight-bearing films being considered 100% correction. The percentage of recurrence between initial postoperative and most recent follow up was then calculated (Figure 1A). A one-way analysis of variance (ANOVA) test and post-hoc Tukey-Kramer tests were used to compare preoperative IMA and HVA and percentage recurrence of IMA and HVA at most recent follow up. Results: There was no significant difference between Lapidus (14.3deg) and mid-diaphyseal osteotomies (12.7deg) in preoperative IMA (p-value=0.26). There was a significant difference between Lapidus (-0.3deg) and mid-diaphyseal (2.8deg) osteotomies for degree of hallux valgus recurrence as measured by IMA between initial postoperative films and final 2-year follow up (p-value=0.009). Lapidus procedure showed a greater magnitude decrease in IMA degrees from preoperation to final follow up compared to distal osteotomy (p-value=0.037) and trended toward significance compared to mid-diaphyseal (p-value=0.056). Mid-diaphyseal osteotomies (30%) showed a statistically significant higher percentage of IMA recurrence compared to Lapidus (-11%) (p-value=0.0014) (Figure 1B). When comparing percentage recurrence of HVA, distal osteotomies had a significantly smaller rate of recurrence when compared to the diaphyseal osteotomies (p-value=0.030). Conclusion: Though Lapidus and mid-diaphyseal osteotomies were performed for patients with a similar preoperative IMA, mid-diaphyseal osteotomies had a significantly higher percentage of recurrence at 2-year follow up compared to Lapidus procedures. Moreover, Lapidus procedures trended toward greater overall of IMA correction compared to mid-diaphyseal osteotomies. When either a Lapidus or mid-diaphyseal osteotomy is indicated, a Lapidus procedure may result in decreased rate of radiographic recurrence of hallux valgus at 2 years.

Category: Bunion; Other Introduction/Purpose: Hallux valgus affects 23 -36% in general populations. The purpose of this study was to evaluate return to run following either a modified Lapidus procedure or a metatarsal osteotomy. We hypothesized that there would be no difference in the ability to return to running. Methods: A Retrospective review of a consecutive series of patients at a single institution with surgical correction was performed. 51 patients were identified. 35 were treated with a metatarsal shaft osteotomy and 16 with a modified Lapidus. Results: No difference was found between the cohorts in terms of age, sex, or pre- operative hallux valgus angle (HVA). 27/35 (77%) with metatarsal shaft osteotomy were able to return to running versus 13/16 (81%) with modified Lapidus. There was no significant difference in the ability to return to running between cohorts (p=1.00). Conclusion: Our study showed no statistical difference for the modified Lapidus versus metatarsal osteotomies relative to return to running.

Full textAbstract:
AbstractA new occurrence of a rare kamafugite near L'Aquila, Abruzzo, is described in detail to characterize its paragenesis and to establish possible genetic links with similar alkaline mafic igneous rocks from the Oricola-Camerata Nuova (OC) volcanic field, ˜20 km to the west. Both occurrences belong to the Umbria-Latium-Ultralkaline-District (ULUD), an igneous district represented by rare kamafugites and carbonatites and distinct from the much more voluminous Roman Region (RR) rocks. The new kamafugite was found in a cave known as Grotta del Cervo (GC), associated with epiclastic and pyroclastic rocks. In the latter, lapilli ash tuff, welded lapilli, ultramafic xenoliths, cognate lithics and pelletal lapilli have been identified. The mineralogy of the welded lapilli comprises, in order of decreasing abundance, diopside, leucite, haüyne, Mg-mica, andraditic garnet, apatite, magnetite, kalsilite and olivine. The rock is carbonate-free. Based on bulk-rock chemistry it is classified as a kamafugite, closely approaching the composition of ULUD kamafugites, according to Sahama's (1974) criteria. Separate lapilli ash tuff, characterized by the same silicate mineralogy as that of the welded lapilli, plus modal carbonate exceeding 10 wt.%, is classified as a carbonatitic kamafugite. Bulk-rock and trace-element compositions confirm that the Grotta del Cervo rocks closely approach the ULUD analogues.The Grotta del Cervo occurrence partially fills the geographical and compositional gap between ULUD rocks and the rocks from the Vulture Complex, also a carbonatite and melilitite locality ˜200 km south of GC, and adds considerably to the bulk of kamafugitic and related rocks lying along the Italian Apennines. The petrogenesis of these kamafugites rocks is discussed and possible mineralogical similarities with the Roman Region rocks are highlighted.

Category: Bunion Introduction/Purpose: Multiple operative techniques have been developed for hallux valgus with varying success. While correction has been traditionally achieved through open surgical approaches, there has been a growing interest in minimally invasive surgical (MIS) techniques. The purpose of this study was to compare clinical and patient-reported outcomes for patients undergoing hallux valgus correction with Lapidus, Scarf and MIS. Our hypothesis was that while a superior clinical correction would be achieved with open techniques there would be similar patient-reported outcomes among open and MIS techniques. Methods: A total of 257 patients who underwent Lapidus (n=82), Scarf (n=82) or MIS (n=93) hallux valgus correction between January 2017- January 2020 at one of two academic institutions by 1 of 9 foot and ankle-fellowship trained orthopedic surgeons were included in this study. Only 3 of 9 performed MIS correction. The average age at the time of surgery 55.4 (range 14-79). Patients were required to have a minimum baseline and 1-year postoperative Patient-Reported Outcomes Measurement Information Scores (PROMIS) and minimum 3-month clinical follow-up. Retrospective chart review was performed to assess the incidence of postoperative complications and reoperations, with an average clinical follow-up of 8 months. Results: All groups had statistically significant differences between pre- and post-operative measurements of HVA, IMA, DMAA, and tibial sesamoid position (<0.05). In addition, the Lapidus group demonstrated change in all parameters measured including Meary's angle, sagittal IMA and Seiberg index. All groups had statistically significant improvement in the PROMIS physical function, pain interference, and global health physical at 1 year (p<0.05). The Lapidus group had significant improvement in all 6 PROMIS domains measured. There were no significant differences in PROMIS score changes from pre to post-op for any PROMIS domain when comparing MIS vs Scarf vs Lapidus. Complications: Minor Complications were classified as infection, symptomatic hardware, delayed union, nerve irritation, transfer metatarsalgia (Lapidus n=14 (17.1%), Scarf n=2 (2.4%), MIS n=15 (16.1%)). Major complications were classified as nonunion, recurrence, hallux varus, recurrence (HVA >20) (Lapidus n=7 (8.5%), Scarf n=9 (11.0%), MIS n=9 (9.7%)). Conclusion: In the last decade, there has been a growing interest in the use of minimally invasive surgical MIS techniques for the treatment of hallux valgus. When compared with traditional open techniques using Lapidus and Scarf osteotomies MIS presents a safe and effective approach to treating hallux valgus.

Full textAbstract:
Category: Midfoot/Forefoot Introduction/Purpose: The Modified Lapidus arthrodesis is a historically established surgical technique for treatment of hallux valgus, providing quality patient outcomes and reproducible results. Addition of a transverse first to second intermetatarsal screw spanning the base of the metatarsals in this procedure can increase stability. However, no study evaluates the radiographical parameters following application of this intermetatarsal screw fixation to procedures without first to second intermetatarsal screw fixation. The purpose of this study was to assess the quality of radiographic parameters between individuals receiving a first to second intertarsal screw fixation to those that did not receive intermetatarsal screw fixation following a non-saw cut Modified Lapidus procedure. Methods: A retrospective review was performed on 74 patients that underwent a Modified Lapidus arthrodesis between 2016- 2020 at a single institution. Preoperative indications for the procedure included first ray instability, first ray hypermobility, hallux abductovalgus, and metatarsal primus elevatus. Inclusion criteria consisted of skeletally mature patients undergoing non sawcut Modified Lapidus procedure. Patients that received the procedure due to a traumatic event or patients with concomitant second metatarsal arthrodesis were excluded. Review of patient's charts was performed. Basic demographics data, implant type, and radiographic parameters including intermetatarsal angle (IMA) and first metatarsal length were obtained from preoperative as well as postoperative films. Results: A total of 74 patients who underwent a Modified Lapidus arthrodesis were included in the study. A group of 43 patients received the Modified Lapidus arthrodesis with the addition of a first to second intermetatarsal screw fixation compared to a group of 31 patients who only received the Modified Lapidus arthrodesis procedure. The average IMA in all patients prior to surgery was 13°. The patients who received intermetatarsal screw fixation had significantly higher IMA reductions between preoperative and postoperative films than those who did not receive the intermetatarsal screw (-8.41° vs. -5.78°, p=.005). The difference in first metatarsal length on preoperative and postoperative films was less in patients who received the screw fixation but this was not statistically significant. Conclusion: The Modified Lapidus procedure is a commonly used procedure to treat hallux valgus. The results of this study found that the addition of a first to second intermetatarsal significantly reduced the IMA when compared to individuals who did not receive the screw construct. These findings will help surgeons further delineate if an intermetatarsal screw is required and how it will contribute to the radiographic parameters of interest.

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: This study aims to compare opioid usage and patient satisfaction with postoperative pain management in similar hallux valgus (HV) patients who underwent minimally invasive distal chevron akin (MIS) correction with patients who underwent modified Lapidus and scarf corrections. We hypothesized that patients who underwent minimally invasive bunionectomy would consume fewer opioids and report similar satisfaction with pain management compared with modified lapidus and scarf patients. Methods: This study is a single center prospective study of 33 patients diagnosed with hallux valgus undergoing MIS bunion correction who received a novel opioid prescribing protocol used by the senior author. Preoperatively, patients undergoing MIS corrections were counseled on the expectations of pain after surgery, received a take home pamphlet, and were prescribed opioids for moderate surgery (5-15 pills). These patients were then compared to a cohort of 25 hallux valgus patients status post Lapidus or scarf bunionectomy who were prescribed 40-60 opioid pills without preoperative coaching or handouts. Patients were excluded if they used opioids or muscle relaxants preoperatively or had a known history of a substance use disorder. Patients completed surveys postoperatively for eight weeks reporting pain level, number of opioid pills consumed, refill requests, and satisfaction with their pain management plan. Results: There was a significant difference (p< 0.001) in mean pills consumed between MIS patients who averaged 2.5 opioid pills (5mg Oxycodone/pill) and modified Lapidus and scarf patients who averaged 25.2 opioid pills (5mg Oxycodone/pill) at all time points (Table 1). There was no significant difference between the ratio of pills taken to pills prescribed between both groups (p>0.05). Patients had comparable levels of pain at all time points (p>0.05). MIS patients did not request any refills, whereas Lapidus and scarf patients requested a total of 5 refills over the course of the study. Conclusion: HV patients who underwent MIS correction achieved equivalent analgesic effect when compared to similar HV patients who underwent Lapidus or scarf procedures. The Lapidus and scarf group received approximately four times the amount of opioids and consumed 11 times the amount of pills. This study demonstrates that HV patients undergoing MIS bunion correction require far fewer opioid pills to achieve the same level of postoperative pain control compared with Lapidus and scarf patients. This study also suggests that a novel postoperative prescribing protocol utilized by the senior surgeon may decrease the number of pills both prescribed and consumed by patients.

ABSTRACT The Belgian rotavirus strain B4106, isolated from a child with gastroenteritis, was previously found to have VP7 (G3), VP4 (P[14]), and NSP4 (A genotype) genes closely related to those of lapine rotaviruses, suggesting a possible lapine origin or natural reassortment of strain B4106. To investigate the origin of this unusual strain, the gene sequences encoding VP1, VP2, VP3, VP6, NSP1, NSP2, NSP3, and NSP5/6 were also determined. To allow comparison to a lapine strain, the 11 double-stranded RNA segments of a European G3P[14] rabbit rotavirus strain 30/96 were also determined. The complete genome similarity between strains B4106 and 30/96 was 93.4% at the nucleotide level and 96.9% at the amino acid level. All 11 genome segments of strain B4106 were closely related to those of lapine rotaviruses and clustered with the lapine strains in phylogenetic analyses. In addition, sequence analyses of the NSP5 gene of strain B4106 revealed that the altered electrophoretic mobility of NSP5, resulting in a super-short pattern, was due to a gene rearrangement (head-to-tail partial duplication, combined with two short insertions and a deletion). Altogether, these findings confirm that a rotavirus strain with an entirely lapine genome complement was able to infect and cause severe disease in a human child.

Full textAbstract:
Otolith growth and microstructural features of fish are essential to the understanding of the early fish lifecycle. This paper assesses the features of otoliths from laboratory-reared larval and juvenile Sinogastromyzon wui (S. wui, 0 to 25 days post-hatching) that were obtained as eggs from the Shilong Reach of Xijiang River between April and August 2021. We observed the development of the three pairs of otoliths (lapilli, sagittae, and asterisci) and compared the shape changes and growth of the lapilli and sagittae, as well as the timing and deposition rate of increments of the lapilli. The lapilli and the sagittae were visible on hatching, whereas the asterisci were present at four days post-hatching (dph). The shape of the sagitta changed more obviously than that of the lapillus, and a strong correlation was observed between sagitta shape changes and fish ontogenesis. The otolith shape greatly modulated during the post-flexion larval stage (Post-FLS), it corresponded with the formation period of individual fins. Analysis of the microstructural features indicated that lapilli were the optimal otolith for age determination and increment deposition rate confirmation. Using regression analysis of the known age and the number of lapillus daily increments, we demonstrated that the lapillus developmental increments were deposited daily, and the first increment formed at two days post-hatching. Our conclusions support employing the lapillus increment deposition rate and the time of the first daily increments in the determination of the age of wild larval and juvenile S. wui.

AbstractTephra beds are considered to be potential failure planes for submarine landslides. Here, we report on an example of a coarse-ash/lapilli-tuff bed influencing translational slides. The studied mass-transport deposit (MTD) is intercalated in the Pleistocene forearc basin fill exposed in east-central Japan. This MTD consists of stacked siltstone blocks resulting from repeated imbricate thrusts branching from the décollement. The basal slide plane is located immediately below a pumice-rich coarse ash/lapilli-tuff bed. The material comprising the slip zone is injected into the overlying coarse-ash/lapilli-tuff bed, suggesting an upwards escape of excess porewater that resulted from elevated pore pressure. To explain this mode of occurrence, we propose that the detachment preferentially occurred at the top and base of the coarse-ash-tuff-rich interval which appears to have been stronger relative to the adjacent silt-dominated interval. The pumiceous coarse-ash and lapilli-tuff bed behaved as a rigid plate on top of the high-pore-pressure slip zone, which sustained the translational slide on the gentle continental slope. Therefore, in translational submarine landslides, the preferential formation of a slide plane is caused by differing frictional resistances in the layered sediments.

In rotaviruses, intragenic recombination or gene rearrangement occurs almost exclusively in the genome segments encoding for non-structural proteins. Rearranged RNA originates by mechanisms of partial sequence duplications and deletions or insertions of non-templated nucleotides. Of interest, epidemiological investigations have pointed out an unusual bias to rearrangements in genome segment 11, notably in rotavirus strains of lapine origin, as evidenced by the detection of numerous lapine strains with super-short genomic electropherotype. The sequence of the full-length genome segment 11 of two lapine strains with super-short electropherotype, LRV-4 and 3489/3, was determined and compared with rearranged and normal cognate genome segments of lapine rotaviruses. The rearranged genome segments contained head-to-tail partial duplications at the 3′ end of the main ORF encoding NSP5. Unlike the strains Alabama and B4106, intermingled stretches of non-templated sequences were not present in the accessory RNA of LRV-4 and 3489/3, while multiple deletions were mapped, suggesting the lack of functional constraints. Altogether, these findings suggest that independent rearrangement events have given origin to the various lapine strains that have super-short genome pattern.

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Minimally invasive techniques (MIS) have focused on first metatarsal osteotomies in hallux valgus correction. Concurrently, new fixation methods allow early weightbearing protocols with the open Lapidus procedure, with nonunion rates comparable to those of more traditional protocols requiring nonweightbearing. We aimed to assess clinical and radiographic results of an MIS-modified Lapidus technique with axial nail fixation (Phantom Lapidus Intramedullary Nail: Paragon28, Englewood, CO USA) and early weightbearing. Methods: After institutional review board approval, the first 30 consecutive percutaneous MIS-modified Lapidus procedures by a single surgeon were retrospectively reviewed. Indications for surgery included moderate to severe hallux valgus deformity with or without first tarsometatarsal joint (TMT) instability, first TMT arthritis, adolescent bunion, and failed prior surgery. All patients initiated weightbearing within 12 days and returned to regular footwear by 6 weeks postoperatively. Patients had a minimum follow-up period of 3 months (average 8.3 months). The pre- and postoperative visual analog scale (VAS) pain scores, intra- and postoperative complications, and need for revision surgery were recorded. Pre- and postoperative radiographs were used to evaluate the hallux valgus angle (HVA), 1-2 intermetatarsal angle (IMA), and sesamoid station. Postoperative radiographs were evaluated for signs of hardware loosening and union of the first TMT arthrodesis site. A postoperative CT scan was obtained if nonunion was suspected. Results: Thirty consecutive percutaneous modified Lapidus procedures were performed in 28 patients. VAS scores improved from 4.1 preoperatively to 1.8 at final follow-up. The IMA decreased 8.3 degrees to an average of 5.9 degrees. The HVA decreased 19.2 degrees to 11.7 degrees. The medial column was shortened by 0.6%. There were no intraoperative complications. There were two reoperations, including one nonunion requiring revision first TMT fusion with autograft and one hallux valgus recurrence requiring a distal chevron osteotomy. There were no wound complications, surgical site infections, hardware complications, postoperative transfer metatarsalgia, or nerve-related problems. Conclusion: The current study provides clinical evidence that the intramedullary nail is a biomechanically stable construct evidenced by the high union rate, lack of hardware failure, and tolerance for early weightbearing. This percutaneous modified Lapidus technique may allow for a low rate of wound complications, accelerated rehabilitaion, and improved cosmesis.

Category: Bunion Introduction/Purpose: Abnormal motion of the first tarsometatarsal (TMT) joint disrupts the anatomic alignment of the metatarsal head, sesamoid complex and proximal first phalanx. This anatomic disruption combined with the deforming forces of the extensor hallucis longus, adductor tendons, and extensor hallucis brevis result in a hallux valgus deformity. First TMT arthrodesis or the Lapidus procedure has been described as treatment for moderate to severe hallux valgus deformities by correcting hypermobility and restoring anatomic alignment of the first ray. The aim of this study was to evaluate the safety of a percutaneous approach to the Lapidus procedure and its relation to anatomic structures. Methods: A percutaneous, modified Lapidus procedure was performed on 19 embalmed cadaveric feet under fluoroscopic guidance. The specimens were then dissected to identify the extensor hallucis longus (EHL), extensor hallucis brevis (EHB), tibialis anterior (TA), median branch of the superficial peroneal nerve (MBSPN), intermediate branch of the superficial peroneal nerve (IBSPN), deep peroneal neurovascular bundle (DPNVB) and saphenous vein (SV). The structures were localized with reference to percutaneous burr and screw placement during the procedure. Results: The tibialis anterior and intermediate branch of the superficial peroneal nerve were a mean of 3.75 millimeters (mm) and 5.08 mm from the closest burr or screw placement. The extensor hallucis longus and extensor hallucis brevis were at greatest risk under the new approach with mean distances of .92 to 4.08 mm to nearby instrumentation. The extensor hallucis longus or extensor hallucis brevis were either directly pierced or <2 mm from instrumentation on 26 occasions. A terminal branch of the saphenous vein was also either pierced or within 2 mm of instrumentation on 4 occasions. The deep peroneal neurovascular bundle and median branch of superficial peroneal nerve were relatively safe, coming within 2 mm of percutaneous burr or screw placement on only 2 occasions each. Conclusion: The minimally invasive percutaneous Lapidus arthrodesis provides a safe alternative to the traditional, open approach for patients with moderate to severe hallux valgus deformities. This may be a beneficial alternative to conventional open Lapidus procedures by minimizing soft tissue dissection. Further clinical studies must be performed to compare deformity correction, fusion rate, and complications with the modified percutaneous Lapidus procedure.
