Xiong A, Luo B, Li M, Chong M, Wang J, Liao S

Sleep Med, 2022 Dec;100:198-205.
PMID: 36113232 DOI: 10.1016/j.sleep.2022.08.025

STUDY OBJECTIVES: Menopausal symptoms exist in most climacteric women, which can harm the quality and satisfaction of life for them. Moreover, a series of ineluctable negative life changes experienced in middle-age usually make the situation more complicated and stressful. We aimed to determine the trajectories and influential factors of sleep quality and menopausal symptoms and their longitudinal interrelationships among climacteric women.
METHODS: A total of 1875 community-dwelling climacteric women were included in this study. The Pittsburgh Sleep Quality Index (PSQI) and the Menopause Rating Scale (MRS) were adopted to assess sleep quality and menopausal symptoms, respectively. Data were collected 4 times from March 2019 to December 2019, at a 3-month interval.
RESULTS: The Cross-lagged analysis showed that worse sleep quality and more severe menopausal symptoms over time after controlling for specified covariates, and more severe menopausal symptoms were predicted by declined sleep quality. The Generalized estimation equation model showed that education level, marital status, chronic diseases, life events, income, and age were the influential factors of sleep quality, while menopausal symptoms were impacted by marital status and income.
CONCLUSIONS: Increasing negative sleep quality and more severe menopausal symptoms over time contribute to the health burden of climacteric women. Menopausal symptoms could be alleviated by sleep quality improvement, which is influenced by education level, marital status, chronic diseases, life events, age, and economic factors.

Mango as a climacteric fruit is known to have increased auxins with concomitant increased ethylene and carbon dioxide production during ripening. Such hormonal properties alongside many other nutritional benefits prepared in the form of compost extract were tested for enhancing production of medicinal bitter gourd of Momordica charantia. This cucurbit was planted on field beds at 0.8 x 0.5 m followed by application of compost extract prepared with anaerobic decomposition of rotting mango fruits, fish wastes of gills and internal organs and brown sugar at different ratios in plastic containers. The results obtained showed that mango:fish wastes:sugar compost extract of 2:1:1 applied to soil around the root collar at 10 ml at fortnight intervals allowed the plants to gain the highest mean number of fruits per plant of 18.3, mean individual fruit weight of 25.95 g or mean yield of 11.80 tonnes per hectare. Mango compost extract is, hence, beneficial in organic production of this medicinal bitter gourd.

Megaselia scalaris (Loew) is one of the best-known diets for the swiftlet. Previous studies have addressed the problem of some mass rearing conditions for this insect; unfortunately, the details of the nutritional composition of the life stages and cost of the breeding materials were insufficiently reported, even though this information is crucial for farming the edible-nest swiftlet. We aimed to investigate the nutritional composition of the life stages of M scalaris on a cost basis using 3 common commercial breeding materials: chicken pellets (CPs), fish pellets (FPs), and mouse pellets (MPs). Modified Association of Official Analytical Chemists (AOAC) proximate and mineral analyses were carried out on the insect's third instar larvae, pupal, and adult stages to determine the nutritional composition. Regardless of the breeding materials, the adult stage of M scalaris had significantly higher crude protein than the other stages; the pupae were rich in calcium, which is required for egg production; and the third instar larvae had the highest amount of crude fat compared with the other stages. Regarding the energy content, there were no significant differences among the stages according to the breeding materials. In terms of nutritional cost, CP was the most economic breeding material and generated the highest amount of nutrients per US dollar (US $). Different life stages of M scalaris were used by the swiftlets by supplying the required nutrients, and future studies should focus on effective diet feeding methods.

The Internet has changed people's life and made the learning methods of college students diversified. Because of the obvious disadvantages brought by the traditional passive classroom learning in China, online self-regulated learning, as a new learning method, has been paid more and more attention from Chinese universities. Online self-regulated learning adapts to the development of society. However, in China, the traditional academic year system limits the freedom of learning of university students. Most students lack learning motivation and affect learning efficiency, so the academic credit system has become an important factor that affects the development of online self-regulated learning. This paper will discuss online self-regulated learning and the academic credit system that affects online self-regulated learning in detail.

Guava is a climacteric fruit which has high nutritional content. It is a highly perishable fruit, undergoes rapid postharvest ripening in a few days under ambient condition. This paper aims to determine the effect of palm stearin and palm kernel olein blends on maintaining the quality of guava during storage. Two different coating formulations of palm stearin (PS) and palm kernel olein (PKOo) blends (1:1 and 3:2) were analysed for their slip melting point (SMP), cohesiveness, viscosity and density. Beeswax was used as a commercial coating for comparison whiles the uncoated guava was used as control. These coatings were applied onto guavas by hand-wipe technique using a sponge. Guavas were dried in corrugated fibre board boxes and stored in an air-conditioned room maintained at 20°C while a chiller maintained at 10°C was used for chilled temperature. Coating pick up, thickness and surface area were measured while guava properties were analysed for coating effect on weight loss, O2 and CO2 gases, firmness and glossiness during storage at ambient temperature (20°C) for 21 days and chilled temperature (10ºC) for 30 days. Microstructure analysis was conducted within 2 days of coating at ambient temperature (20ºC). The results obtained indicated that 1:1 PSPKOo blends had higher cohesiveness compared to beeswax. Both PSPKOo blends significantly (p

Cantaloupes continue to ripen after harvesting which is caused by ethylene production due to climacteric behaviour during postharvest storage. In this study, the cantaloupe fruits harvested at commercial maturity were evaluated for quality attributes during three weeks of storage at 10°C and a relative humidity (RH) of 90±5%. In addition, fresh-cut samples were stored for a further 19 days at 2°C and 87% RH. The fresh-cut samples were prepared on a weekly basis by dipping into deionised water (control) at 2°C for 1 minute. The effect of postharvest storage of cantaloupe on the physico-chemical properties and microbial activity was observed prior to fresh-cut processing. It was found that firmness, luminosity (L*), and titratable acidity (TA) decreased, while total soluble solids (TSS), pH, TSS:TA ratio, microbial activity (total plate count (TPC) and yeast and mould (YM)) of the fresh-cut increased over the postharvest storage period of the fruit. Meanwhile, the orange colour and the intensity (hue angle, hab, and chromaticity) of the flesh did not differ significantly during storage. The cantaloupe stored for three weeks at a low temperature indicated a successful potential for fresh-cut processing due to good maintenance of the product quality.

PMID: 7799826

Questionnaires (4000) on experience of menopausal symptoms in Singaporean women aged 40-55 were distributed by students. In total, 524 envelopes were returned (13.1%) and of these 420 were analyzed. Of these, 366 were classified as either pre-, peri- or postmenopausal on the basis of their menstrual patterns. Menopausal symptoms in this sample of Singaporean women were, in general, similar to those experienced in the West though the prevalence was low compared to European studies. No significant differences in individual symptoms were found between the 3 groups but, taken together, symptoms were significantly highest in the perimenopausal and lowest in the other menopausal groups. In the postmenopausal group 50% had been menopausal for at least 1 year at 50.5 years.

PMID: 7799827

In an attempt to gather data on the menopause in Malaysia, 400 women (13% Chinese, 70% Malays and 16% Indians), representing the three major ethnic groups in Malaysia, were interviewed. The majority (76%) of these women were still married and living with their husbands and 63% of them were working. Most of them (90%) had attained menarche by the age of 15 years and 50% of them had married before the age of 20. Their reproductive record was good, since 76% of them had 3 or more children who were still alive. The mean age at menopause in the Malaysian women studied was 50.7 years. Analysis of the climacteric symptoms reported showed significant differences in the vasomotor and nervosity indices in the perimenopausal and postmenopausal groups. Eighty percent (80%) of the women saw no need to consult a doctor about their climacteric symptoms. When they did, most of them (84%) received medication, but 43% of them did not comply with the prescribed treatment. Dyspareunia and urinary incontinence were evidently regarded as embarrassing complaints in all three groups, since around 80% of the women did not seek medical advice. This is not surprising in view of the fact that 89% of them rated their health as good.

Classical homeopathy was shown to be beneficial in climacteric syndrome in many studies, but the clinical effect is unclear. To inspect if individualized classical homeopathy has a role in treating complaints after surgical menopause through real world case, we present a case of a 54-year-old Russian woman treated with individualized classical homeopathy for multimorbid conditions after surgical menopause examined for changes from homeopathic treatment. We assessed changes in climacteric symptoms, changes in comorbidities, and the general well-being of the patient. The woman had severe climacteric syndrome, pelvic inflammatory disease, dyslipidemia, obesity, hepatic steatosis, pancreatic lipomatosis, gall bladder disease, and mild subclinical hypothyroidism to begin with. She was treated with individualized classical homeopathy and followed up for 31 months. She was relieved of the vasomotor symptoms and psychological disturbances of climacteric syndrome, her weight reduced, the ultrasound scan showed absence of lipomatosis/gall bladder disease/hepatic steatosis. Blood tests showed reduction of thyroid stimulating hormone and a balance in the lipid status. Individualized classical homeopathy may have a role in the climacteric syndrome and comorbidities after surgical menopause. The efficacy of homeopathic therapy in climacteric problems must be scientifically investigated further.

Rabbit strains find immense application in biomedical research with every strain having their discrete advantage in specific research endeavor. Acceptability of rabbit strains as laboratory animals owes to their breeding ease, availability, cost-effectiveness, ethical conveniences, larger size, compared to rats and mice, and responsiveness. With respect to different life phases, the article displays that one human year is equivalent to: (1) in developmental phase, 56.77 days for New Zealand White (NZW) and New Zealand Red (NZR) rabbits, 71.01 days for Dutch belted and Polish rabbits, and 85.28 days for Californian rabbits; (2) in the prepubertal phase, 13.04 days for NZW and Dutch belted, 15.65 days for NZR and Californian, and 10.43 days for Polish rabbits; (3) in the adult phase, 18.25 days for NZW and Californian rabbits, 22.75 days for NZR, and 12 days for Dutch Belted and Polish rabbits; (4) during reproductive senescence, 42.94 days for NZW, NZR and Californian rabbits, 28.62 days for Dutch belted, and 25.05 days for Polish rabbits; (5) in the post-senescence phase, 50.34 days for NZW, 25.17 days for NZR, Dutch Belted and Californian and 31.46 days for Polish rabbits. The laboratory rabbit strains differ in various physiological, developmental and genetic make-ups, which also reflect upon the correlation of their age at different life stages with that of a human. The present article aids selection of laboratory rabbit strain of accurate age as per experimental need, by precisely relating the same with age of human considering different life stages.

PMID: 25606203 MyJurnal

Women at the end of their reproductive age often complain of climacteric symptoms which can be quite debilitating at times. Physiological changes due to deficient oestrogen have received global attention in the search for an acceptable and safe measure to improve quality of life for women with these complaints. Hormone replacement therapy (HRT) used to be the main treatment for menopausal symptoms. Lately there are concerns about its possible adverse effects of increasing risks of breast malignancy, heart diseases, etc. Complementary Alternative Medicine (CAM) plays a significant role in relieving these climacteric symptoms especially in women with contraindications to hormonal therapy and in those who are worried of its adverse effects. It is important for women to be aware of these CAM to provide them with options to improve their quality of life. This paper explores other pharmacological and non-pharmacological measures as alternatives to hormone replacement therapy (HRT), to assess how useful and reliable they are according to available scientific evidence.

Climacteric and menopause in seven South-east Asian countries

Boulet MJ, Oddens BJ, Lehert P, Vemer HM, Visser A

PMID: 7799822

The menopause is universal, but what about the climacteric? In an attempt to answer this question, a study was conducted in seven south-east Asian countries, namely, Hong Kong, Indonesia, Korea, Malaysia, the Philippines, Singapore and Taiwan. Samples of approximately 400 women in each country were questioned about a number of climacteric complaints, incontinence and dyspareunia, consultation of a physician, menopausal status and several background characteristics. Special care was taken to overcome linguistic and cultural problems, and the data collected were kept as objective as possible. From the results obtained we were able to show that the climacteric was indeed experienced in south-east Asian countries, although in a mild form. The prevalence of hot flushes and of sweating was lower than in western countries, but was nevertheless not negligible. The percentages of women who reported the more psychological types of complaint were similar to those in western countries. The occurrence of climacteric complaints affected perceived health status. A physician was consulted for climacteric complaints by 20% of the respondents, although this was most frequently associated with the occurrence of psychological complaints and less so with that of hot flushes and sweating. The median age at menopause (51.09) appeared to be within the ranges observed in western countries. Ethnic background and age at menarche were found to have a significant influence on age at menopause. The study clearly demonstrated that climacteric complaints occur in south-east Asia. The findings suggest, however, that vasomotor-complaint-related distress might be 'translated' into psychological complaints, which are more frequently considered to warrant consulting a physician.
