The Relationship Between the Percentage of Skeletal Muscle (SMP) and the Emergence of Degenerative Diseases (Hypertension) in Posyandu for the Elderly Mugi Sehat

Degenerative disease is a condition of continuous decline in body function with increasing age. Hypertension is a degenerative disease that is often suffered by the elderly. The aging process results in changes in body composition, often without being accompanied by weight changes. Increasing age in the elderly will experience functional limitations caused by changes in body composition, one of which is the Percentage of Skeletal Muscle. The purpose of this study was to determine the relationship between the percentage of skeletal muscle and the emergence of degenerative diseases (hypertension) in the elderly at the Mugi Healthy Elderly Posyandu. The instruments in this study used a Digital Sphygmomanometer to measure blood pressure and an Omron Karada Scan Body Composition Monitor Model HBF-375 to measure Skeletal Muscle Percentage. This research method uses a cross-sectional research design. The sample in this study is 58 people. The research was conducted at the Mugi Sehat Elderly Posyandu in the working area of the 2022 UPTD Kembar I health center in May-June 2023. The sampling technique in this study uses total sampling and data analysis using the Spearman Rank test. The results of this study from the bivariate analysis showed that there was no relationship between the Percentage of Skeletal Muscle and the emergence of degenerative diseases (hypertension) in the elderly at the Mugi Healthy Elderly Posyandu, namely the Percentage of Skeletal Muscle with hypertension P value = 0.576 (CC=-0.075).

Level of disability in stroke survivors in the greater accra region of ghana: a cross-sectional study

Abstract Background Many stroke survivors in low- and middle-income countries such as Ghana live with various degrees of disabilities. Insight into the level of disability and its determinants in stroke survivors has become very important. This study aimed to assess disability and determinants in stroke survivors in the Greater Accra Region of Ghana. Methods One hundred and eight community-dwelling stroke survivors undergoing outpatient physiotherapy rehabilitation were sampled for the study. The World Health Organization disability assessment schedule (WHODAS) questionnaire was used to assess the level of disability in the participants. Sociodemographic and clinical data were gathered to help assess the determinants of disability. Association between sociodemographics and disability, and clinical characteristics and disability were determined using chi-square/Fisher’s exact test. p values less than 0.005 were considered statistically significant. Results Most of the study participants were reported to have moderate to severe disabilities in their bodily function. Age, gender, marital status, and employment status were found to be associated with the level of disability in stroke survivors. Conclusion Disability and its determinants in stroke need to be given much attention as disability affects the ability of stroke survivors to function independently.

Tapeworm infection affects sleep-like behavior in three-spined sticklebacks

Sleep is a complex and conserved biological process that affects several body functions and behaviors. Evidence suggests that there is a reciprocal interaction between sleep and immunity. For instance, fragmented sleep can increase the probability of parasitic infections and reduce the ability to fight infections. Moreover, viral and bacterial infections alter the sleep patterns of infected individuals. However, the effects of macro-parasitic infections on sleep remain largely unknown, and measuring sleep in non-model organisms remains challenging. In this study, we investigated whether macro-parasite infections could alter sleep-like behavior of their hosts. We experimentally infected three-spined sticklebacks (Gasterosteus aculeatus), a freshwater fish, with the tapeworm Schistocephalus solidus and used a hidden Markov model to characterize sleep-like behavior in sticklebacks. One to four days after parasite exposure, infected fish showed no difference in sleep-like behavior compared with non-exposed fish, and fish that were exposed-but-not-infected only showed a slight reduction in sleep-like behavior during daytime. Twenty-nine to 32 days after exposure, infected fish showed more sleep-like behavior than control fish, while exposed-but-not-infected fish showed overall less sleep-like behavior. Using brain transcriptomics, we identified immune- and sleep-associated genes that potentially underlie the observed behavioral changes. These results provide insights into the complex association between macro-parasite infection, immunity, and sleep in fish and may thus contribute to a better understanding of reciprocal interactions between sleep and immunity.

Quality of Life and Mental Development of Children with Acute Respiratory Infections Undergoing Hospital Treatment

Preserving the health of the younger generation is a priority multidisciplinary task. For a more comprehensive and individual assessment of the functioning of the child's body against the background of acute viral infections, a technique for determining the quality of life based on subjective perception was used, on the basis of which patients are classified into the first or second classes of quality of life. The paper examines the interrelationships of health, quality of life and mental development of preschool children with acute respiratory infections being treated in the pediatric department. Some children were found to have a reduced quality of life, not only in the group of children with acute respiratory infections, but also in the group of healthy children. There were significantly more patients with grade 2 quality of life in the main group. According to the results of correlation analysis using Spearmanʼs rank correlation coefficient, it was found that the quality of life is interrelated with psycho-emotional and the intellectual development of the child. Based on the study of the quality of life of patients in the pediatric department, it is possible to implement an individual approach to assessing the condition of the child as a whole and against the background of the disease, for high-quality further treatment and monitoring, for the organization of preventive measures.

A 10-year (2014-2023) review of complementary food development in sub-Saharan Africa and the impact on child health.

Complementary foods (CFs) commonly consumed by infants and young children (IYC) in sub-Saharan Africa (SSA) are processed using either single or multi-grain ingredients through simple technologies such as fermentation, malting and roasting. Interestingly, CFs (e.g., ogi, kunu, and dabo) are prepared and fed to infants alongside breastmilk until they are completely weaned up to the infant's second birthday. The grains used for preparing CFs can be contaminated with bacterial and chemical contaminants as a result of poor harvesting, handling or storage practices. The stage at which IYC are introduced to CFs is of utmost importance as it aids in addressing malnutrition and improving their overall health and well-being. Complementary feeding practices across SSA are influenced by socio-economic, cultural and geographical factors such that improper introduction can result in dire health consequences including immune suppression, severe foodborne diseases, poor child growth and development, and sometimes death from malnutrition. Malnutrition often occurs from inadequacies of nutrient intakes and assimilation which affect the ability to maintain normal body functions such as growth, learning abilities, resistance to and recovery from diseases. In SSA, IYC malnutrition still poses an enormous concern, therefore indicating the need for intervention strategies such as the promotion of indigenous crops and elevating traditional knowledge and technologies for formulating CFs. This paper clearly highlights the diversity of CFs in SSA, ingredients utilized, processing techniques, contamination by bacteria and chemicals, and demonstrates the consequences of consuming contaminated CFs, and their influence on IYC health as well as approaches to ensuring safety and scaling up indigenous CFs.

Assessment of Prognostic Factors, Clinical Features Including the Microbiome, and Treatment Outcomes in Patients with Cancer of Unknown Primary Site

Introductions: cancer of unknown primary site (CUP) is a heterogeneous group of cancers in which metastases are found, and the primary tumor is not detected with available diagnostic methods. CUP is a disease that has not been fully researched, and its biology is unclear. The clinical characteristics of CUP are variable, but the prognosis of patients is usually unfavorable, and the possibilities of radical treatment are limited. The microbiome is the genes and gene products of microorganisms residing in a human body. In recent years, thanks to the use of next-generation sequencing, it is possible to assess the impact of the microbiome on human body functions. Head and neck cancers, due to the rich microbiome of this area, are influenced by it, and dysbiosis may be a risk factor for the development of cancer. Objective of this work: the aim of this study was to evaluate prognostic factors, clinical features including the microbiome, and treatment outcomes in patients with cancer of unknown primary site. Results: in the study group, increased numbers of bacteria of the phyla Bacteroides, Fusobacteria, Bacillota, Actinomycetota, Actinobacteria, and Candidatus were detected, while Firmicutes and Proteobacteria were detected in smaller numbers. Independent predictors of CUP occurrence were the following: leukocyte count of at most 6.49 × 103/mm, bacteria from the Proteobacteria phylum in the microbiome below 11.6%, Firmicutes below 22.1%, and Actinobacteria at least 11.0%. Increased numbers of Porphyromonas and Fusobacterium bacteria were associated with the risk of radiotherapy complications and shortened survival rate. Conclusions: clinical diagnosis and treatment of patients with CUP is complicated and difficult due to the lack of consensus on this issue. Treatment and prognosis of patients with CUP is unsatisfactory. The clinical value of the influence of the microbiome on the development, course, and treatment of cancer is becoming increasingly important. The microbiome may become a marker of response to anticancer treatment and the risk of its complications. Immunity modulation with the microbiome provides opportunities for further research on improving the effectiveness of oncological treatment. Fusobacterium and Porphyromonas seem to be the bacteria most important for the development of cancer, also worsening the prognosis of patients by increasing the risk of complications of radiotherapy and shortening the survival rate of patients. Streptococcus and Lactobacillus seem to be bacteria that reduce the risk of cancer, reduce the risk of complications, and improve the prognosis of patients. Total protein deficiency and elevated inflammatory markers are also important predictors of cancer risk.

Influence of Walking, Manual Techniques, and Elastic Resistance Exercise on Shoulder Posture in Healthy Elderly Individuals.

The world population is rapidly aging; therefore, it is necessary to respond to this challenge in time. One of the typical involutional signs of old age is a hunched posture combined with a forward position of the shoulder girdle. This posture negatively impacts various bodily functions, postural stability, and strain on the musculoskeletal system. We aimed to evaluate the effect of walking and walking combined with manual therapy/resistance exercise on scapular positioning in healthy elderly individuals. Participants of experimental groups underwent a 4-week training session that involved walking and manual techniques/resistance training applied 2x/week. Participants of the control group maintained their usual daily habits. Our results showed statistically significant improvement in scapular positioning of the left shoulder in participants who underwent regular walking combined with resistance exercise training. These results suggest that regular walking combined with resistance training, when properly dosed, may beneficially influence scapular positioning in healthy elderly individuals.

Olfactory Receptors and Tumorigenesis: Implications for Diagnosis and Targeted Therapy.

Olfactory receptors (ORs) are a class of G protein-coupled receptors (GPCR) widely distributed in olfactory sensory neurons and various non-olfactory tissues, serving significant physiological and pathological functions in the human body. Increasing evidence reveals the heightened expression of olfactory receptors in tumorous tissues and cells alongside normal tissues. Olfactory receptors have demonstrated influence over tumor cell proliferation and metastasis, establishing a close relationship with tumor initiation and progression. This review highlights the specific molecular actions and signaling pathways of olfactory receptors in the development of human tumors. The potential for precise tumor diagnosis and targeted therapy through therapeutic targeting of olfactory receptors as an adjunct anticancer treatment strategy is being considered.

Changes in biopsychosocial factors based on transportation independence among older adults: A one-year study post-COVID-19 movement restrictions

IntroductionThe global COVID-19 pandemic prompted widespread lockdown measures, impacting transportation systems and specifically affecting the mobility of older adults, which could result in changes to their biophysical, psychological and social health, or better known as biopsychosocial health. However, limited information exists regarding the alterations in the biopsychosocial aspects of older adults during and after the COVID-19 movement restrictions, as well as their association. The objective of this study is to investigate the biopsychosocial dynamics associated with navigating transportation during and after the recovery phase of COVID-19 pandemic. Additionally, it aims to determine the association between transportation independence status and various biopsychosocial factors. MethodsA sub-sample of 100 individuals aged 60 years and above (mean age ± SD: 68.4 ± 5.3), from earlier cross-sectional study were recruited in a one year follow up study. Face-to-face interviews were conducted by the same researcher from baseline to obtain older adults’ sociodemographic health status, anthropometric measurements, functional status, depressive symptoms, nutritional status, cognitive status, visual assessment, physical activity and physical performance and transportation independence. Bivariate logistic regression was performed to examine the association. ResultsWhile there were no significant changes in transportation independence among older adults during and after the COVID-19 movement restriction, there were noticeable increases in outdoor mobility and certain changes in biopsychosocial factors. Results revealed higher fat mass (Adj OR = 1.20, 95% CI: 1.03–1.41, p < 0.05), poorer performance in Timed up and Go (TUG) (Adj OR = 1.40, 95% CI: 1.03–1.88, p < 0.05) test, poorer Hand Grip Strength (HGS) (Adj OR = .85, 95% CI: .74–.98, p < 0.05) and changes in Instrumental Activities of Daily Living (IADL) (p < 0.05) are associated with restricted transportation in older adults. ConclusionThe findings of this study highlight the importance of biopsychosocial health factors, such as body composition, physical performance, and function, which may be influenced by transportation independence among older adults.

Nesting Technique : It’s Effects on Preterm Cardiorespiratory Indicators

Background: Premature infant born with immature body system, their organs are not ready for extra uterine life, and they are unable to deal with external stress, which could alter body functions such as cardio-respiratory function. In addition, poor muscle tone increases the chance of developing an abnormal posture. To reduce this instability, applying developmental care such as nesting is vital to promote cardio-respiratory stability, maintain position, and reduce stress in preterm. Objectives: The study aims to assess the impact of the nesting technique on preterm cardio-respiratory parameters in various positions (supine, prone, and right lateral). Methodology: The research used randomized controlled trial design. By simple random sampling technique was choose 60 preterm infant, and they were divided into four groups equally (supine, prone, right lateral, and control group). The cardio-respiratory parameters (heart rate, respiratory rate, and oxygen saturation) were measured before and after applying the nesting and positioning techniques for 3 consecutive days. Data were analyzed by Statistical Package for Social Sciences (SPSS) program. Results: The study results showed a significant difference in the mean score of cardio-respiratory after three days of nesting technique with lateral, supine, and prone position groups at p= 0.000. While the control group showed there was non-significant change in the mean score of HR, RR, and Spo2 at p &gt; 0.05. Conclusion: The Study concluded that the nesting technique was effective for stabilizing the cardio-respiratory parameters of preterm infants. The authors recommended routinely using nesting with the ideal position technique in preterm as a part of developmental care at the neonatal intensive care unit

Use of antimicrobial peptides to eliminate immunodeficiency in acne patients

Acne is an urgent problem in modern dermatology. According to various authors, acne accounts for 23 to 35 % of dermatological visits to a dermatovenerologist. The management of this disease is complex, lengthy and multi-stage, requiring a combination of various diagnostic and therapeutic techniques and an individualised approach. It is also necessary to take into account the presence of comorbidities, as the treatment of patients with acne should be based on the concept of patient-centred medical care, which is aimed not at treating a particular disease but at maximising the normalisation of the functioning of the human body as a whole. Objective — to determine the drug’s effectiveness based on antimicrobial peptides (AMPs) in eliminating immunodeficiency in patients with acne. Materials and methods. The dynamics of immunogram indicators was studied in 35 patients with acne who had immunodeficiency of the first degree as a comorbid disease. All the subjects underwent a course of 10 intramuscular injections of the drug based on AMP — 2 ml once every 2 days. Results and discussion. In all subjects, the use of AMP contributed to the normalisation of immunogram parameters to reference values. Its tolerability was good or satisfactory. Conclusions. AMP, administered according to the proposed regimen, is a highly effective immunocorrective agent that normalises immunograms in patients with acne and eliminates grade I immunodeficiency. Patients tolerated the drug well or satisfactorily. It is recommended for use in patient-centred medical care for patients with acne with comorbid immunodeficiency.

State affect and body image effects of body positive social media content within a female chronic illness sample

Body positivity refers to a movement, popularized on social media, that encourages the normalization and acceptance of bodies diverging from sociocultural ideals, specifically within marginalized communities. Previous studies suggest that briefly viewing body positive social media content may lead to increased body satisfaction and positive affect in young women relative to thin-ideal and appearance-neutral content. Diminished body functionality and appearance change due to chronic illness poses a unique challenge to positive body image in young adults living with chronic illness. Typical body positive social media content may not be useful for this community since chronic illnesses are often not outwardly depicted, so the current study aimed to examine the state effects before and after viewing body positive social media content in a sample of young women (N=201) with at least one self-reported chronic illness. Participants (Mage = 29.4, SD = 6.74; 79.2 % white) were randomly assigned to view one of two sets of 10 images: chronic illness body positive and typical body positive. Participants completed a Visual Analogue Scale (VAS) pre- and post-stimuli exposure. Findings from repeated measures ANOVA revealed significant interaction between time and group for negative affect (F(1198) = 4.402, p =.037) and broad conceptualization of beauty (F(1199) = 4.288, p =.040), such that those exposed to the chronic illness stimuli reported a larger reduction in negative affect and an increase in conceptualization of beauty beyond the non-chronically ill ideal post-exposure. Thus, exposure to body positive social media content inclusive of chronic illness may be more useful in stabilizing affect and promoting greater positive body image within the community. These findings highlight the importance of inclusive body positive portrayals in terms of dimensions beyond weight and shape to account for the effects of diminished body functionality.

Lower adaptive immunity in invasive Egyptian geese compared to sympatric native waterfowls

Successful invasive species increase their spreading success by trading-off nutritional and metabolic resources allocated to reproduction and range expansion with other costly body functions. One proposed mechanism for the reallocation of resources is a trade-off with the immune function and the regulation of oxidative status. Relying on a panel of blood-based markers of immune function and oxidative status quantified in an invasive species (Egyptian goose) and two native competing species (mallard and mute swan) in Germany, we tested the hypothesis that the invasive species would have (i) lower investment in immune function, (ii) lower levels of oxidative damage, and (iii) no higher antioxidant defences compared to the native species. We found lower levels of adaptive immune markers (lymphocytes and immunoglobulin Y), in the invasive species compared to the two native species. Innate immune profile was generally similar between Egyptian geese and mallards. By contrast, mute swans showed higher levels of heterophils and lysozymes, and lower levels of bacteria killing ability compared to both Egyptian geese and mallards. Mute swans also showed higher levels of haemolysis and haemagglutination, but lower levels of monocytes and haematocrit compared to Egyptian geese. Reactive oxygen metabolites, a marker of oxidative damage, were higher in mallards and lower in Egyptian geese compared to the other waterfowl species, while levels of antioxidants were generally similar among the three species. Our results point to a reduced investment in adaptive immune function in the invasive species as a possible resources-saving immunological strategy due to the loss of co-evolved parasites in the new colonised habitats, as observed in a previous study. A lower investment in immune function may benefit other energy-demanding activities, such as reproduction, dispersal, and territoriality, while maintaining relatively higher innate immunity is beneficial since invasive species mainly encounter novel pathogens. Results pointed out also other important species-specific differences in baseline immune status, supporting previous findings on the relationship between species' body mass and immune profile.

Nutrition Role in Maintaining Health and Preventing Disease

Abstract: A person's body depends on nutrients, which are the components of food that drive biological activity. A healthy lifestyle includes having a good diet. All that we eat and drink is what human bodies are made of and how they are powered. Proteins, lipids, carbs (sugars, dietary filter), vitamins, and minerals are the several categories that they belong to nutrients, and each one of these performs a crucial job. Building all body parts, including muscle, bone, teeth, and blood. Generating energy and maintaining the body's functionality. A complete condition of emotional and physical well-being is referred to as being "healthy." Optimal nutrition, which supplies all nutrients at sufficient and suitable levels, is the cornerstone of good health and the forerunner of prevention. The most significant ongoing environmental influences influencing our growth, development, functional abilities, and health are the meals we eat and the nutrients they should include. If we want to successfully reduce the excessive premature morbidity and death from our top killer diseases-heart disease, cancer, and stroke-we must educate the general population, especially health professionals, about nutrition. Our lifestyle choices, such as eating, disciplining our health habits, and exercising, will significantly impact our individual health and lower the costs of our existing catastrophic medical treatment. The main environmental factors that continue to impact our ability to grow and develop health are the meals we eat and the nutrients they should include. In this review, we discuss how nutrients play an important role in preventing our body from disease and maintaining health.

The connection between aging, cellular senescence and gut microbiome alterations: A comprehensive review.

The intricate interplay between cellular senescence and alterations in the gut microbiome emerges as a pivotal axis in the aging process, increasingly recognized for its contribution to systemic inflammation, physiological decline, and predisposition to age-associated diseases. Cellular senescence, characterized by a cessation of cell division in response to various stressors, induces morphological and functional changes within tissues. The complexity and heterogeneity of senescent cells, alongside the secretion of senescence-associated secretory phenotype, exacerbate the aging process through pro-inflammatory pathways and influence the microenvironment and immune system. Concurrently, aging-associated changes in gut microbiome diversity and composition contribute to dysbiosis, further exacerbating systemic inflammation and undermining the integrity of various bodily functions. This review encapsulates the burgeoning research on the reciprocal relationship between cellular senescence and gut dysbiosis, highlighting their collective impact on age-related musculoskeletal diseases, including osteoporosis, sarcopenia, and osteoarthritis. It also explores the potential of modulating the gut microbiome and targeting cellular senescence as innovative strategies for healthy aging and mitigating the progression of aging-related conditions. By exploring targeted interventions, including the development of senotherapeutic drugs and probiotic therapies, this review aims to shed light on novel therapeutic avenues. These strategies leverage the connection between cellular senescence and gut microbiome alterations to advance aging research and development of interventions aimed at extending health span and improving the quality of life in the older population.

Deciphering the importance of nanoencapsulation to improve the availability of bioactive molecules in food sources to the human body

Various bodily functions are maintained, and health benefits are provided by food-derived bioactive components. Fruits and vegetables contain numerous beneficial components, including vitamins, minerals, antioxidants, enzymes, and phytonutrients. However, the body's ability to absorb these substances at a given rate and degree frequently limits their bioavailability. If food-derived bio actives are used as therapeutic or dietary interventions, this limitation can result in low efficacy and suboptimal results. Recently, nanotechnology has been a useful method for increasing the bioavailability of bioactive compounds produced from food. Active ingredients can be delivered and absorbed more efficiently with the help of nanotechnology. By altering their size or surface properties, bioactive components can be made more soluble, permeable, and bioavailable through nanotechnology. The present review will provide an overview of the various bioactive components, the application of nanotechnology to improve the availability of bioactive molecules to humans and animals, and the challenges and safety concerns associated with nanotechnology in the production of food-derived bioactive molecules.

Risk assessment of PM2.5 from fossil energy consumption on the respiratory health of the elderly

Air pollution mainly comes from fossil energy consumption (FEC), and it brings great threat to public health. The respiratory system of the elderly is highly susceptible to the effects of air pollution due to the decline in body functions. PM2.5 is a major component of air pollution, so the study of the impact of PM2.5 generated by FEC on the respiratory health of the elderly is of great significance. The existing studies have focused more on the effect of PM2.5 on mortality, and this paper is a useful addition to the existing studies by examining the effect of PM2.5 from FEC on the health of the elderly from the perspective of prevalence. In this paper, the binary Logistic regression model was used to calculate the exposure-response relationship coefficient for respiratory health in older adults using the data in 2018 from the Chinese Longitudinal Healthy Longevity Survey. And referring to the Dynamic Projection model for Emissions in China, the changes in the number of older persons suffering from respiratory diseases due to PM2.5 from FEC in the baseline scenario, the clean air scenario, and the on-time peak-clean air scenario were predicted. The results indicated that: (1) PM2.5 from FEC mainly came from coal; (2) PM2.5 from FEC was detrimental to the respiratory health of the elderly, and older seniors were more affected as they age; (3) In the on-time peak-clean air scenario, the number of elderly people suffering from respiratory diseases due to PM2.5 from FEC was growing at the slowest rate. Based on the above results, this paper raised recommendations for reducing the effect of PM2.5 from FEC on the health of the elderly.
