RESUMO
This paper reports and examines the results of qualitative research on the use of local cancer terminology in urban Bagamoyo, Tanzania. Following recent calls to unify evidence and dignity-based practices in global health, this research locates local medical sociolinguistics as a key place of entry into creating epistemologically autonomous public health practices. We used semistructured ethnographic interviews to reveal both the contextual and broader patterns related to use of local cancer terminologies among residents of Dunda Ward in urban Bagamoyo. Our findings suggest that people in Bagamoyo employ diverse terms to describe and make meanings about cancer that do not neatly fit with biomedical paradigms. This research not only opens further investigation about how ordinary people speak and make sense of the emerging cancer epidemic in places like Tanzania, but also is a window into otherwise conceptualisations of 'intervention' onto people in formerly colonised regions to improve a health situation. We argue that adapting biomedical concepts into local sociolinguistic and knowledge structures is an essential task in creating dignity-based, evidence-informed practices in global health.

BACKGROUND: Musculoskeletal conditions are the leading cause of disability worldwide and disproportionally affect individuals in low-income and middle-income countries. There is a dearth of evidence on musculoskeletal problems among refugees, 74% of whom reside in low-income and middle-income countries. QUESTIONS/PURPOSES: (1) What proportion of refugees in Nyarugusu Camp, Kigoma, western Tanzania, are affected by musculoskeletal problems and what are the characteristics of those individuals? (2) What are the characteristics of these musculoskeletal problems, including their causes, location, and duration? (3) What forms of healthcare do those with musculoskeletal problems seek, including those for both musculoskeletal and nonmusculoskeletal problems? METHODS: We conducted a cross-sectional study among refugees in Nyarugusu Camp, using the Surgeons OverSeas Assessment of Surgical Need tool. The Surgeons OverSeas Assessment of Surgical Need tool is a validated population-based survey tool developed for use in limited-resource settings that is intended to determine the prevalence of surgical disease in a community. It uses a cluster random sampling methodology with house-to-house data collection in the form of a verbal head-to-toe examination that is performed by a trained community healthcare worker. A total of 99% responded, and 3574 records were analyzed. The mean age of respondents was 23 ± 18 years, with under 18 as the most-represented age group (44% [1563]). A total of 57% (2026) of respondents were women, 79% (2802 of 3536) were generally healthy, and 92% (3297 of 3570) had visited a camp medical facility. Only records endorsing musculoskeletal problems (extremity or back) were included in this analysis. Using all refugees surveyed as our denominator and refugees who endorsed a musculoskeletal problem (extremity or back) as the numerator, we calculated the proportion of refugees who endorsed a musculoskeletal problem. We then analyzed the characteristics of those endorsing musculoskeletal problems, including their healthcare-seeking behavior, and the characteristics of the musculoskeletal problems themselves. RESULTS: Among 3574 refugees interviewed, 22% (769) reported musculoskeletal problems, with 17% (609) reporting extremity problems and 7% (266) reporting back problems. Among all people surveyed, 8% (290) reported current extremity problems while 5% (188) reported current back problems. Among those reporting musculoskeletal problems, respondents younger than 18 years were the most-represented age group (28% [169 of 609]) whereas respondents between 30 and 44 years of age were the most-represented age group for back problems (29% [76 of 266]). Wounds from an injury or trauma (24% [133 of 557]) and acquired disability (24% [133 of 557]) were the most-common causes of extremity problems, whereas acquired disability (53% [97 of 184]) followed by a wound not from injury or trauma (25% [45 of 184]) were the most common causes of back problems. Fifty percent (303) of those with extremity problems characterized it as disabling, whereas 76% (203) of those with back problems did. CONCLUSION: Over one of five refugees endorsed musculoskeletal problems, which are most often caused by acquired disease and injury. These musculoskeletal problems are often characterized as disabling, yet only slightly more than half have sought treatment for problems. This warrants further research on care-seeking behavior in this setting, and emphasizes that investing in the spectrum of musculoskeletal health systems, including medical management and rehabilitation services, is critical to decreasing disability caused by musculoskeletal problems. LEVEL OF EVIDENCE: Level IV, prognostic study.
RESUMO
WHO defines vaccine hesitancy as delay in acceptance or refusal of vaccines despite the availability of vaccine services. It is a complex phenomenon that varies through time, place and vaccines. In this comment, we highlight the context-specific variation of Covid-19 vaccine hesitancy in Tanzania. We suggest Covid-19 hesitancy in Tanzania is influenced with high burden of infectious disease, poor testing capabilities and demographic characteristics.

Introduction/Background: Since 2020, China has implemented unprecedented digital health surveillance over citizens and residents in response to the coronavirus disease 2019 pandemic. We explore the implementation of Health Code (jiankang ma), a contract-tracing and risk assessment app for coronavirus disease 2019, in China. By engaging with the concept of 'ocular ethics', we ask why and how some populations become invisible in China's Health Code surveillance system. Methods: This study used an ethnographic approach to critically examine the role of digital technology in the coronavirus disease 2019 pandemic governance. Three months of participant observation and 20 interviews were conducted to understand the design of Health Code and the situation of homeless population. Results: We find that China's digital health surveillance during the coronavirus disease 2019 pandemic has failed to cover the homeless population, who either fail to access Health Code or find ways to avoid its mandatory health surveillance. We further summarize four problems resulting in their exclusion, including the loss of ID cards, access to smartphones and phone numbers, problematic design and elastic surveillance, and the neglect of homeless community's precarious living situation. Conclusion: Situating our work in the literature on theories of surveillance and anthropology of pandemics, we argue that without recognizing the structural problems embedded in homelessness, a large number of poor and homeless migrants are rendered invisible in this data-driven health surveillance, which further pushes them into social exclusion.
RESUMO
Chemotherapy-induced cognitive impairment (CICI) is a novel clinical condition characterized by memory, learning, and motor function deficits. Oxidative stress and inflammation are potential factors contributing to chemotherapy's adverse effects on the brain. Inhibition of soluble epoxide hydrolase (sEH) has been proven effective in neuroinflammation and reversal of memory impairment. The research aims to evaluate the memory protective effect of sEH inhibitor and dual inhibitor of sEH and COX and compare its impact with herbal extracts with known nootropic activity in an animal model of CICI. In vitro sEH, the inhibitory activity of hydroalcoholic extracts of Sizygium aromaticum, Nigella sativa, and Mesua ferrea was tested on murine and human sEH enzyme as per the protocol, and IC50 was determined. Cyclophosphamide (50 mg/kg), methotrexate (5 mg/kg), and fluorouracil (5 mg/kg) combination (CMF) were administered intraperitoneally to induce CICI. The known herbal sEH inhibitor, Lepidium meyenii and the dual inhibitor of COX and sEH (PTUPB) were tested for their protective effect in the CICI model. The herbal formulation with known nootropic activity viz Bacopa monnieri and commercial formulation (Mentat) were also used to compare the efficacy in the CICI model. Behavioral parameter such as cognitive function was assessed by Morris Water Maze besides investigating oxidative stress (GSH and LPO) and inflammatory (TNFα, IL-6, BDNF and COX-2) markers in the brain. CMF-induced CICI, which was associated with increased oxidative stress and inflammation in the brain. However, treatment with PTUPB or herbal extracts inhibiting sEH preserved spatial memory via ameliorating oxidative stress and inflammation. S. aromaticum and N. sativa inhibited COX2, but M. Ferrea did not affect COX2 activity. Lepidium meyenii was the least effective, and mentat showed superior activity over Bacopa monnieri in preserving memory. Compared to untreated animals, the mice treated with PTUPB or hydroalcoholic extracts showed a discernible improvement in cognitive function in CICI.

Despite significant advances in the understanding of the global burden of surgical disease, limited research focuses on access to health and surgical services among refugees, especially in east Africa. The goal of this study was to describe patterns of access to transportation to health services among Congolese and Burundian refugees in Tanzania. We utilized cluster random sampling to perform a large, cross-sectional study in Nyarugusu refugee camp, Tanzania using an adapted version of the Surgeon Overseas Assessment Tool (SOSAS). We randomly selected 132 clusters out of 1472 clusters, randomly selected two people from all households in those clusters. Data analysis was performed in STATA (Stata Version 16, College Station, TX). A total of 3560 participants were included in the study including 1863 Congolese refugees and 1697 Burundian refugees. The majority of refugees reported they were generally healthy (n = 2792, 79.3%). The most common period of waiting to be seen at the health center was between three and 5 h (n = 1502, 45.8%), and over half of all refugees waited between 3 and 12 h to be seen. There was heterogeneity in other intra-camp referral networks (e.g. to and from traditional healer and hospital). Finally, a low percentage (3%) of participants reported leaving the refugee camp to seek health care elsewhere, and Congolese refugees were more likely to pursue self-referral in this manner. To our knowledge, this is the largest study focused on access to transportation among refugees in Tanzania and sub-Saharan Africa. Most participants reported financial difficulty always affording transportation costs with significant wait times occurring once arrived at the hospital. Our study does suggest that some independent health care seeking did occur outside of the camp-based services. Future research may focus more specifically on barriers to timely servicing of patients and patterns of self-referral.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).

Background: Gastroesophageal reflux disease (GERD) is a chronic, relapsing disorder. In this era of modern and fast-track lifestyle and food habits, the incidence of GERD is rapidly increasing. Currently, proton pump inhibitors (PPIs) are the primary choice of treatment. However, the associated side effects and a high relapse rate give rise to the need to explore alternative therapies. Objective: The study aimed to evaluate HAGE-101912, an herbal combination, in different experimental models of GERD. Methods: Antacid activity was assessed based on H+/K+ATPase inhibitory activity of parietal cells using artificial gastric juice. Tonic contraction of the lower esophageal sphincter (LES) was evaluated using an AD Instrument. A GERD model of the pylorus and fundus ligation (preventive and curative models) in rats was selected to assess the efficacy of HAGE-101912 at a dose of 250 mg/kg body weight, and various parameters such as the gastric pH, gastric volume, total acidity, gross esophageal ulcer index, and histopathological changes were evaluated. The prokinetic activity was assessed using the phenol red method. Results: HAGE-101912 increased the acid-neutralizing capacity (P < 0.001), decreased H+/K+ATPase activity (P < 0.01), and increased the contraction of the LES. In the preventive model, HAGE-101912 significantly reduced the gastric acid volume (P < 0.01), total acidity (P < 0.001), and gross esophageal ulcer index (P < 0.01); increased the gastric acid pH (P < 0.01); and protected the esophageal epithelium. In addition, HAGE-101912 increased gastric emptying and gastrointestinal transit through its prokinetic activity (P < 0.05). Conclusion: HAGE-101912 has a beneficial effect in GERD as it effectively inhibits the H+/K+ATPase, increases the gastric pH, restores the LES function, protects the esophageal epithelium, and increases gastric emptying and transit.
RESUMO
Background: African migrants in China face social, structural, and cultural barriers to human immunodeficiency virus (HIV) testing with scarce information on their HIV testing behaviours. This study estimated the prevalence of HIV testing and its social and behavioural correlates to understand how to better provide HIV testing services for African migrants living in China. Methods: We conducted a national cross-sectional survey among adult African migrants who lived in China for more than one month between January 19 to February 7, 2021. The survey was disseminated online through six African community organizations and via participant referrals. We collected data on HIV testing behaviours and history of HIV testing, social, and cultural factors and applied univariate and multivariable logistic regression to identify testing correlates. Results: Among a total of 1305 participants, 72.9% (n = 951/1305) tested for HIV during their stay in China and yielded a self-reported HIV prevalence of 0.4% (n = 4/951). The most common reason for HIV testing was to comply with Chinese residence policy requirements (88.5%, n = 842/951); for not testing was "no need to be tested" (79.4%, n = 281/354). We found most African migrants have experienced low acculturation stress (54.5%, n = 750/1305), low social discrimination (65.6%, n = 856/1305), have a moderate stigma towards HIV (54.3%, n = 709/1305), and low community engagement around sexual health and HIV topics. In multivariable analysis, African migrants who were students (adjusted odds ratio (aOR) = 3.36, 95% CI = 2.40-4.71), living in student dormitories (aOR = 3.86, 95% CI = 1.51-9.84), received health services in China in past year (aOR = 1.67, 95% CI = 1.25-2.23), had lifetime sexually transmitted infections (STI) testing (aOR = 1.95, 95% CI = 1.23-3.10), had HIV testing before coming to China (aOR = 13.56, 95% CI = 9.36-19.65), and those engaged in community discussions of HIV and sexual health (aOR = 2.77, 95% CI = 1.31-5.83) were more likely to test for HIV in China. Conclusions: Despite 73% of African migrants having tested for HIV in China, there are unmet needs and barriers identified in our study, such as language barriers. Access to HIV knowledge and testing services were the most important enablers for testing, including studentship, past STI/HIV testing, and community discussion on sexual health. Culturally appropriate and community-based outreach programs to provide information on HIV and testing venues for African migrants might be helpful to promote testing uptake.

OBJECTIVES: In order to prevent overburdening of higher levels of care, national healthcare systems rely on processes of referral, including for refugee populations which number 26 million globally. The goal of this study is to use data from a population-based household survey to describe patterns of referral services among a population of Congolese and Burundian refugees living in Tanzania. DESIGN: Cross-sectional survey using cluster randomised sampling. SETTING: Nyarugusu refugee camp, Kigoma, Tanzania. PARTICIPANTS: 153 refugees. PRIMARY OUTCOME: Referral compliance. SECONDARY OUTCOMES: Proportion of referrals that were surgical; proportion of referrals requiring diagnostic imaging. RESULTS: Out of 153 individuals who had been told they needed a referral, 96 (62.7%) had gone to the referral hospital. Of the 57 who had not gone, 36 (63%) reported they were still waiting to go and had waited over a month. Of the participants who had been referred (n=96), almost half of the participants reported they were referred for a surgical problem (n=43, 45%) and the majority received radiological testing at an outside hospital (n=72, 75%). Congolese refugees more frequently had physically completed their referral compared with Burundians (Congolese: n=68, 76.4% vs Burundian: n=28, 43.8%, p<0.001). In terms of intracamp referral networks, most refugees reported being referred to the hospital or clinic by a community health worker (n=133, 86.9%). CONCLUSION: To our knowledge, this is the first community-based study on patterns of referral healthcare among refugees in Tanzania and sub-Saharan Africa. Our findings suggest patients were referred for surgical problems and for imaging, however not all referrals were completed in a timely fashion. Future research should attempt to build prospective referral registries that allow for better tracking of patients and examination of waiting times.

NGOs recruit religious leaders as health actors in Sub-Saharan Africa. Program designers both construct religious leaders as opponents of family planning interventions who discourage their congregants from using family planning and as proponents who persuade their congregants to use them. This article investigates a family planning project that recruited religious leaders in Morogoro, Tanzania. Research findings show that binary talk obfuscates the structural underpinning of high fertility rates. The construction of static binaries of good and bad religious leaders observed mismatches with peoples' own realities and it misses the lifelike nuances of actors' own ethical action.

BACKGROUND: Malaria is one of the prime reasons for medical consultation and the major cause of morbidity and mortality in Mali. To assess and understand the dynamics of social representations of malaria, the anthropological research was conducted in the Wayerema II neighbourhood of the health district of Sikasso, southern Mali. METHODS: This was an ethnographic study conducted qualitatively in 2011 and 2016 through informal conversations, 70 semi-structured interviews, and participant observations with key actors. The observations, conversations, and interviews investigated local people's perceptions and knowledge about malaria, and how and to what extent the cultural and popular representations of the disease can have an impact on therapeutic routes. RESULTS: Mosquitoes are the principal agent of the transmission of malaria. However, the ubiquitous yet casually-claimed aetiological agents, causative, nosographic entities differ from-although sometimes integrated into-the biomedical dimension. For example, some communities perceive Kono, a complicated and pernicious form of malaria that often occurs among children, to originate from a supernatural force. "Bird disease" is another term used for Kono in Mali and other West African countries. Thus, overall, Kono is defined through the entanglements with cultural factors, namely the idiosyncratic habits, customs, and beliefs of the population of Wayerema II neighbourhood in the health district of Sikasso, Southern Mali. Wayerema II residents particularly tend to link therapeutic recourse amongst the afflicted not only to biomedical models but to sociocultural and popular perceptions and representations of malaria. CONCLUSION: In the findings, self-medication through both traditional and modern medical techniques was the most frequent therapeutic modality. Hence, the integration of local popular knowledge with the biomedical register can contribute to a comprehensive understanding of social representations and perceptions of malaria, and qualitative improvements in the malaria control programme.

IMPORTANCE: Surgery is a foundational aspect to high functioning health care systems. In the wake of the Lancet Commission on Global Surgery, previous research has focused on defining the burden of surgical conditions among a pediatric population, however these studies often fail to include forced migrant or refugees. The goal of this study was to estimate the prevalence of pediatric surgical conditions among refugees in east Africa. METHODS: We used the previously validated Surgeons OverSeas Assessment of Surgical Need (SOSAS) that utilizes cross-sectional design with random cluster sampling to assess prevalence of surgical disease among participants aged 0 to 18 years in Nyarugusu refugee camp, Tanzania. We used descriptive and multivariable analyses including an average marginal effects model. RESULTS: A total of 1,658 participants were included in the study. The mean age of our sample was 8.3 ± 5.8 years. A total of 841 participants (50.7%) were male and 817 participants (49.3%) were female. A total of 513 (n = 30.9%) reported a history or presence of a problem that may be surgical in nature, and 280 (54.6%) of them reported the problem was ongoing or untreated. Overall, 16.9% had an ongoing problem that may be amenable to surgery. We found that increasing age and recent illness were associated with having a surgical problem on both our multivariable analyses. CONCLUSION: To our knowledge, this is the first and largest study of prevalence of surgical conditions among refugee children in sub-Saharan Africa. We found that over 16% (one-in-six) of refugee children have a problem that may be amenable to surgery. Our results provide a benchmark upon which other studies in conflict or post-conflict zones with refugee or forced migrant populations may be compared.

Background: Although ulcerative proctitis (UP) and anal fissure (AF) are common anorectal diseases, there are no appropriate experimental models to screen the drugs intended for these conditions. In this context, existing experimental models mimicking these diseases were modified and the polyherbal formulation, HPLF-111624 was evaluated in these models. Objective: To establish animal model for UP and AF and to evaluate polyherbal formulation, HPLF-111624 in these disease models. Methods: An experimental model of UP was selected based on the modification of the ulcerative colitis model using different concentrations of acetic acid. The concentration used for induction were 2.5%, 5% and 10% v/v and different weights used to induce AF were 25 g, 50 g and 100 g, which were selected based on the severity of inflammation, fecal score, gross pathology, and histopathological evaluation. Furthermore, these animal models were used to evaluate the efficacy of HPLF-111624, a polyherbal formulation known to be beneficial in anal diseases. Results: Acetic acid at 5% produced typical pathological changes that resembled UP, with a significant increase in the fecal score, gross lesion, and histopathological changes. Similarly, among the three weights, physical injury with a 100 g weight produced significant changes in the histopathological score in the model of AF. Intervention with HPLF-111624 at doses of 250 and 500 mg/kg b.wt., showed a reduction in the inflammatory cytokines and a significant improvement in the histopathological findings in both the conditions. Conclusion: The results showed that the modified experimental models for UP and AF resemble the human pathological conditions and are simple, versatile and may be used for screening drugs intended for these conditions. Intervention with HPLF-111624 was found to be effective in improving the pathological state of UP and AF.
RESUMO
OBJECTIVE: The goal of this study was to estimate the prevalence of surgical conditions among refugees in East Africa. BACKGROUND: Surgery is a foundational aspect to high functioning health care systems. In the wake of the Lancet Commission on Global Surgery, previous research has focused on defining the burden of surgical conditions in low- and middle-income countries. Despite numbering over 80 million people globally, forced migrant populations have often been neglected from this body of research. METHODS: We administered a validated survey using random cluster sampling to determine surgical need among refugees in western Tanzania. Primary outcome was history or presence of a surgical problem. Analysis included descriptive and multivariable logistic regression including an average marginal effects model. RESULTS: We analyzed data from 3,574 refugee participants in East Africa. A total of 1,654 participants (46.3%) reported a history or presence of at least one problem that may be surgical in nature. Of those 1,654 participants who did report a problem 1,022 participants (61.8%) reported the problem was still ongoing. Multivariable analysis revealed several factors associated with having a surgical problem (increasing age, occupation, illness within past year). CONCLUSION: To our knowledge, this is the first and largest population-based survey in estimating the prevalence of surgical disease among refugees in sub-Saharan Africa. Our results imply that more than one-in-four refugees has an ongoing surgical problem, suggesting over double the burden of surgical need in refugee populations compared to non-refugee settings.

In the past two decades, religious leaders have garnered increased interest from health ministries and NGOs as promoters, educators, and implementers of sensitive health programs such as family planning in several African countries. While religious leaders' role as public health actors has been well-documented, there are few ethnographic accounts of how religious leaders engage with public health programs, especially family planning. Informed by twelve months of ethnographic study in three rural and peri-urban locations in Kilombero district in 2014-2016, this article examines how Muslim religious leaders experienced and negotiated their role as implementers of family planning services. Governments and NGOs seek religious leaders' social capital to increase community's knowledge of and demand for family planning as well as to diffuse the community's moral anxieties surrounding its use. Participant observation and interviews, however, show that religious leaders selectively engage with family planning projects, balancing project demands, their own interests and the existing norms and perceptions in the community. Religious leaders stood beside other team members promoting condoms, but they remained silent themselves on condom promotion selecting instead to speak on the dangers of teenage pregnancy. Tensions, power differentials and a mélange of interests, existing and emergent, set the stage for religious leaders to selectively engage with the family planning project. Selective engagement was beneficial for both parties. Religious leaders received training on modern family planning, gained symbolic capital by associating with a powerful NGO, and expanded their social networks while government officials and NGOs received indirect support for family planning programs.

Natural bioactive compounds derived from plant-based products are known for their biological immunomodulatory activities. They possess systemic pleiotropic effects, minimal side effects, and very low toxicities. Plant-based bioactive compounds have tremendous potential as natural therapeutic entities against various disease conditions and act as anti-inflammatory, antioxidant, anti-mutagenic, anti-microbial, anti-viral, anti-tumour, anti-allergic, neuroprotective, and cardioprotective agents. A herbal formulation extract including five biologically active compounds: Apigenin, Quercetin, Betulinic acid, Oleanolic acid, and ß-Sitosterol can impart several immunomodulatory effects. In this review, we systematically present the impact of these compounds on important molecular signaling pathways, including inflammation, immunity, redox metabolism, neuroinflammation, neutropenia, cell growth, apoptosis, and cell cycle. The review corroborates the beneficial effect of these compounds and shows considerable potential to be used as a safer, more cost-effective treatment for several diseases by affecting the major nodal points of various stimulatory pathways.
RESUMO
BACKGROUND: Numerous studies have examined the role of community health workers (CHWs) in improving the delivery of health services and accelerating progress towards national and international development goals. A limited but growing body of studies have also explored the interactions between CHWs' personal, communal and professional identities and the implications of these for their profession. CHWs possess multiple, overlapping roles and identities, which makes them effective primary health care providers when properly supported with adequate resources, but it also limits their ability to implement interventions that only target certain members of their community, follow standard business working days and hours. In some situations, it even prevents them from performing certain duties when it comes to sensitive topics such as family planning. METHODS: To understand the multiple identities of CHWs, a mixture of qualitative and ethnographic methods was utilized, such as participant observation, open-ended and semi-structured interviews, and focus group discussions with CHWs, their supervisors, and their clients. The observation period began in October 2013 and ended in June 2014. This study was based on implementation research conducted by the Connect Project in Rufiji, Ulanga and Kilombero Districts in Tanzania and aimed to understand the role of CHWs in the provision of maternal and child health services in rural areas. RESULTS: To our knowledge, this was the first study that employed an ethnographic approach to examine the relationship between personal, communal and professional identities, and its implications for CHWs' work in Tanzania. Our findings suggest that it is difficult to distinguish between personal and professional identities among CHWs in rural areas. Important aspects of CHW services such as personalization, access, and equity of health services were influenced by CHWs' position as local agents. However, the study also found that their personal identity sometimes inhibited CHWs in speaking about issues related to family planning and sexual health. Being local, CHWs were viewed according to the social norms of the area that consider the gender and age of each worker, which tended to constrain their work in family planning and other areas. Furthermore, the communities welcomed and valued CHWs when they had curative medicines; however, when medical stocks were delayed, the community viewed the CHWs with suspicion and disinterest. Community members who received curative services from CHWs also tended to become more receptive to their preventative health care work. CONCLUSION: Although CHWs' multiple roles constrained certain aspects of their work in line with prevalent social norms, overall, the multiple roles they fulfilled had a positive effect by keeping CHWs embedded in their community and earned them trust from community members, which enhanced their ability to provide personalized, equitable and relevant services. However, CHWs needed a support system that included functional supply chains, supervision, and community support to help them retain their role as health care providers and enabled them to provide curative, preventative, and referral services.

Muscle wasting diseases are gradually increasing with the increase in global life expectancy. This study was designed to evaluate the efficacy of HIM-CHX, a herbal combination of Boswellia serrata, Cissus quadrangularis, and Withania somnifera, on Sarcopenia. The effects of HIM-CHX on parameters such as muscle mass, grip strength, motor coordination, gait, locomotor activity and endurance were measured in rats. In addition to this, inflammatory cytokines, myokine and growth hormone levels were also evaluated. In the first experiment, HIM-CHX was administered orally to rats at the dose of 125, 250, and 500â¯mg/kg body weight for 12â¯weeks. At the end of the treatment period, muscle mass, grip strength, motor coordination and proinflammatory cytokines were evaluated. In the second experiment, HIM-CHX was administered orally at a dose of 500â¯mg/kg body weight for 4â¯weeks and gait analysis, locomotor activity, endurance and endogenous antioxidant activity were evaluated. The animals treated with HIM-CHX showed a significant improvement in gastrocnemius muscle weight, carcass weight, gait, locomotor activity and endurance. HIM-CHX exerts its effect by reducing the levels of TNF-α, IL-6, and Myostatin while increasing the IGF-1 levels which are the typical biomarkers of muscle wasting. Furthermore, the study findings indicate that HIM-CHX has the potential to correct the pathophysiological changes associated with sarcopenia.

The objective of the present study was to evaluate "DXB-2030," a polyherbal combination of Trigonella foenum-graecum, Aloe vera, Sphaeranthus indicus, Nardostachys jatamansi, and Symplocos racemosa extracts in an experimental model of testosterone propionate (TP), induced polycystic ovary syndrome (PCOS) in female rats. Thirty animals were divided into 3 groups of 10 each; group 1 served as normal control; group 2 was administered with TP and served as positive control; along with TP, group 3 was treated with "DXB-2030" at a dose of 100 mg/kg p.o., for 60 days. At the end of the study period, the animals were subjected for the estimation of serum testosterone levels, oral glucose tolerance test (OGTT), weight of the ovaries, estrous cycle, and histopathological evaluation. An in vitro assay on GLUT4 expression was carried out to understand the effect of "DXB-2030" on insulin resistance. Results showed that treatment with "DXB-2030" reversed the TP-induced changes by increasing the GLUT4 expression and decreasing the body weight, testosterone levels, AUC of glucose in OGTT, and the cystic follicles of the ovaries, thus indicating its beneficial effect in PCOS by ameliorating the metabolic dysfunction and reproductive impairment, which are the pathophysiological conditions associated with PCOS. From the results obtained, it can be concluded that "DXB-2030" was effective in the management of experimental PCOS and hence may be recommended in the treatment of PCOS.
