Abstract (sommario):

postnatal development. Both twitch contraction time and half-relaxation time decreased progressively with age. Correspondingly, the force-frequency curve was shifted to the left early in development compared with adults. The ratio of peak twitch force to maximum tetanic force decreased with age. Fatigue resistance of the diaphragm was highest at birth and then progressively decreased with age. At birth, most diaphragm muscle fibers stained darkly for myofibrillar adenosinetriphosphatase after alkaline preincubation and thus would be classified histochemically as type II. During subsequent postnatal development, the proportion of type I fibers (lightly stained for adenosinetriphosphatase) increased while the number of type II fibers declined. At birth, type I fibers were larger than type II fibers. The size of both fiber types increased with age, but the increase in cross-sectional area was greater for type II fibers. On the basis of fiber type proportions and mean cross-sectional areas, type I fibers contributed 15% of total muscle mass at birth and 25% in adults. Thus postnatal changes in diaphragm contractile and fatigue properties cannot be attributed to changes in the relative contribution of histochemically classified type I and II fibers. However, the possibility that these developmental changes in diaphragm contractile and fatigue properties correlated with the varying contractile protein composition of muscle fibers was discussed.

Abstract (sommario):

Introduction : Pour l’OMS, le post-partum s’achève six à huit semaines après la naissance. Les facteurs de stress postnatal ont été appréciés chez des mères lors de la consultation postnatale. Une observation entre la perception du stress postnatal et celle du stress postaccouchement a été menée. Matériel et méthode : Une étude descriptive des mères (n = 133), puis comparative entre primipares (n = 56) et multipares (n = 77) a été réalisée à l’aide de l’échelle psychométrique Post-Natal Perceived Stress Inventory (PNPSI). Résultats : Les primipares se perçoivent significativement (p < 0,05) plus stressées sur le facteur de la relation avec leurs nourrissons, alors que les multipares sont significativement (p < 0,05) plus stressées sur la place du père auprès de l’enfant. La mort inattendue du nourrisson (MIN) est l’élément le plus stressant pour les mères, notamment les primipares (66 %). Ce stress est corrélé significativement (p < 0,05) avec celui qu’elles perçoivent sur leur fatigue, le sentiment d’être débordée et de ne pas savoir si leurs nourrissons mangent suffisamment. Le stress sur les rythmes et la santé du nourrisson est très significativement (p < 0,001) corrélé avec celui sur la MIN. À la consultation postnatale, elles sont moins stressées par la fatigue et l’allaitement contrairement au séjour en maternité, et 71 % ne sont plus du tout stressées par les soins à donner à leurs enfants. Conclusion : Développer l’entretien postnatal précoce permettrait de soutenir les parents dans leurs rôles et de renseigner les mères sur la MIN à domicile.

Abstract (sommario):

The present study was designed to assess the effects of combined pre- and postnatal undernutrition on the in vitro contractile and fatigue properties of the rat diaphragm during development. In vitro direct stimulation of costal diaphragm from control (CTL) and undernourished (UN) rats was done on postnatal days 1, 4, 14, 21, 30, 40, 50, and 60. Combined pre- and postnatal undernutrition resulted in stunted animal growth but did not alter the diaphragm-to-total body weight ratio. Twitch contraction time, half-relaxation time, and force-frequency relationships were not consistently affected by undernutrition. Specific twitch force and specific tetanic force were also unchanged in the UN group. Fatigue resistance was high and comparable in UN and CTL groups at days 1 and 4. At day 14 and thereafter, fatigue resistance declined but was consistently higher in the UN than in the CTL group. We conclude that combined pre- and postnatal undernutrition results in a significant increase in fatigue resistance of the diaphragm compared with CTL, whereas diaphragm muscle contractile properties are not appreciably affected by prolonged undernutrition.

Abstract (sommario):

The effects on the rat diaphragm of fatigue induced by low- and high-frequency stimulation (at 5 Hz for 1.5 min and 75 Hz for 1 min) were examined during postnatal development. Experiments were performed on isolated costal diaphragm strips. Before stimulation, twitch contraction time and half relaxation time were longest in the neonate and decreased significantly between weeks 1 and 6. Correspondingly, the specific twitch tension (corrected for cross-sectional area) increased progressively with age. After either low- or high-frequency fatigue, the force recovery was complete in 1- and 2-week-old rats, whereas the force production progressively decreased in older rats. In addition, the neonate diaphragm further enhanced its force selectively after high-frequency fatigue. It is concluded that the rat diaphragm is comparably resistant to fatigue during the early postnatal period, whether fatigue is induced by low- or by high-frequency stimulation. This suggests that postnatal changes in diaphragm contractile and fatigue properties may be related to changes in the process of force production. The possibility is discussed that a higher total muscle oxidative potential and the mechanisms leading to force potentiation in the neonate might explain the fatigue resistance.

Abstract (sommario):

Introduction.Physical activity is important for health and well-being; however, rates of postnatal physical activity can be low. This paper reports the secondary outcomes of a trial aimed at increasing physical activity among postnatal women.Methods.More Active MuMs in Stirling (MAMMiS) was a randomised controlled trial testing the effect of physical activity consultation and pram walking group intervention among inactive postnatal women. Data were collected on postnatal weight, body composition, general well-being, and fatigue. Participants were also interviewed regarding motivations and perceived benefits of participating in the trial.Results.There was no significant effect of the intervention on any weight/body composition outcome or on general well-being at three or six months of follow-up. There was a significant but inconsistent difference in fatigue between groups. Qualitative data highlighted a number of perceived benefits to weight, body composition, and particularly well-being (including improved fatigue) which were not borne out by objective data.Discussion.The MAMMiS study found no impact of the physical activity intervention on body composition and psychological well-being and indicates that further research is required to identify successful approaches to increase physical activity and improve health and well-being among postnatal women.

Abstract (sommario):

Pain is pain, but it's not all the same the international association for the study of pain. Maternal fatigue is a subjective experience of whole body, encompassing the physical, emotional and cognitive functioning in the postpartum mothers. Aromatherapy is become a frequently used non biomedical method of managing pain and it also helps in promoting, relaxation, mood stimulation, sleep promotion. The present study aims to assess the effectiveness of aromatherapy on after pain and fatigue among postnatal mothers. A quantitative quasi experimental research design was conducted among 30 postnatal mothers by using a convenience sampling technique and 15 were divided in control and experimental group. The demographic data was collected using structured interview questionnaire. The pre-test was done to assess level of after pain by visual analogue scale and level of fatigue-by-fatigue assessment scale for both the experimental and control group. The experimental group was given aromatherapy by lavender oil, the control group was given a routine care and then the post test was done. The study results show that the level of fatigue was considerably reduced in the experimental group than the control group in the post test at p<0.005. This indicates aromatherapy is effective non pharmacological method and cost-effective method to treat after pain and fatigue among postnatal mothers. The result of the study is it was concluded that aromatherapy as no side effects and it is easy and comfortable method which can be practiced to treat after pain and fatigue.

Abstract (sommario):

We studied the in vitro contractile and fatigue properties of the rat external abdominal oblique (EAO) and costal diaphragm (DIA) muscles during postnatal development. Isometric twitch contraction (CT) and half-relaxation (RT1/2) times were longer in both the EAO and DIA muscles during the early postnatal period and decreased with age. In the first postnatal week, the CT and RT1/2 were longer in the EAO than the DIA muscle. At 14 days of age and thereafter, the CT and RT1/2 were shorter in the EAO than in the DIA muscle. Force-frequency relationships of the EAO and DIA muscles changed during postnatal development such that the relative force (percent maximum) generated at lower frequencies (less than 15 pulses/s) decreased with age. Moreover the relative force generated by the EAO muscle at lower frequencies was greater than that of the DIA muscle during the early postnatal period but less than that of the DIA muscle in adults. The specific force of both the EAO and DIA muscles increased progressively with age. There were no differences in specific force between the EAO and DIA muscles at any age. The fatigability of the EAO and DIA muscles was comparable during the early postnatal period and increased in both muscles with postnatal development. In adults the EAO muscle was more fatigable than the DIA muscle. We conclude that the contractile and fatigue properties of the EAO and DIA muscles undergo significantly different postnatal transitions, which may reflect their functional involvement in sustaining ventilation.

Abstract (sommario):

Objective: The objective of the study was to identify the incidence and knowledge of minor ailments of puerperium among postnatal mothers and to develop an information leaflet on the management of minor ailments of puerperium.Methods: A quantitative approach with descriptive design and convenience sampling technique was used in this study. With these methods, the researcher selected 100 postnatal mothers attending Obstetrics and Gynecology ward, AIMS, Kochi. A semi-structured questionnaire along with a checklist was used to assess the knowledge and the incidence of minor ailments among postnatal mothers.Result: The result showed that the common incidence of minor ailments was afterpain (67%), perineal discomfort (50%), constipation (43%), and fatigue (67%). Majority of the postnatal mothers had average knowledge (65%) level, and some of them had good knowledge (21%), and some of them had poor knowledge (14%).Conclusion: The study revealed that the main four problems of minor ailments of puerperium were afterpain, perineal discomfort, constipation, and fatigue. Number of studies from different part of the world, including India, shows that a large proportion of postnatal mother experiences minor ailments of puerperium. This provides evidence for giving importance to minor ailments of puerperium. Researchers also provided a baseline information leaflet on the management of minor ailments of puerperium.

Abstract (sommario):

Caring for a new child is a significant, demanding, and time consuming role, often associated with increased stress. Postnatal depression is one possible outcome of increased stress and research has highlighted the importance of detecting depression in new mothers. However fatigue a correlate of depression, has only recently become a focus of research among health professionals. Understanding the nature of fatigue and its management within the postnatal period, the focus of this study, may reduce its impact on women’s lives. This longitudinal study explores changes in intensity, physical, mental and emotional dimensions of fatigue, factors associated with higher levels of fatigue, the impact of fatigue on women’s usual activities, and strategies for managing fatigue. Self-administered structured questionnaires gathered data form 504 women at 1, 6, 12 and 24 weeks after birth. Reliable and valid instruments were used to measure the relationship between the defined factors and the outcome of fatigue at the various time points. State anxiety was a consistently strong predictor of fatigue intensity across time and group. Women sought to manage their fatigue by using self-care practices and asking for help from family and friends. This research highlights two issues for health professionals – care of new mothers must include recognition that higher levels of state anxiety are associated with higher levels of postnatal fatigue: ongoing assessment of fatigue and the strategies used to manage it is essential beyond the early postnatal period
