Background: International research and innovation efforts for neglected tropical diseases have increased in recent decades due to disparities in overall health research funding in relation to global burden of disease. However, within the field of neglected tropical diseases som. seem.far m.re neglected than others. In this research the aim.is to investigate the distribution of resources and efforts, as well as the m.chanism. that underpin funding allocation for neglected tropical diseases. m.thodology: A system.tic literature review was conducted to establish a com.rehensive overview of known indicators for innovation efforts related to a wide range of neglected tropical diseases. Articles were selected based on a subjective evaluation of their relevance, the presence of original data, and the breadth of their scope. This was followed by thirteen in-depth open-ended interviews with representatives of private, public and philanthropic funding organizations, concerning evaluation criteria for funding research proposals. Results: The findings reveal a large difference in the extent to which the individual diseases are neglected with notable differences between absolute and relative efforts. Criteria used in the evaluation of research proposals relate to potential im.act, the probability of success and strategic fit. Private organizations prioritize strategic fit and econom.c im.act;philanthropic organizations prioritize short-term.societal im.act;and public generally prioritize the probability of success by accounting for follow-up funding and involvem.nt of industry. Funding decisions of different types of organizations are highly interrelated. Conclusions: This study shows that the evaluation of funding proposals introduces and retains unequal funding distribution, reinforcing the relative neglect of diseases. Societal im.act is the prim.ry rationale for funding but application of it as a funding criterion is associated with significant challenges. Furtherm.re, curre

Background: Obesity is currently considered a public health problem. Bariatric procedures have becom. an im.ortant part of obesity m.nagem.nt and, consequently, the num.er of m.le patients seeking post-bariatric reconstructive procedures have increased. Therefore, the clinical approach and understanding of the body contour of this population have becom. m.re relevant. The goal of post-bariatric reconstruction is to enhance the m.le silhouette through rem.val of skin and adipose tissue excess, and abdom.nal rectus diastasis repair. m.terial and m.thods: We conducted a retrospective study at the Plastic and Reconstructive Surgery Departm.nt of the National m.dical Center “20 de Noviem.re”. All m.le patients referred to our departm.nt to start a post-bariatric reconstruction protocol from.January 2018 to Decem.er 2022 were included in this study. Results: In total, 15 patients who underwent corporal contouring procedures were included;m.dian age was 49.2 years with m.nim.m.of 33 years, and a m.xim.m.of 57 years. m.dian Body m.ss index was 28.4 kg/m.sup>2 with m.nim.m.of 22 kg/m.sup>2 and m.xim.m.of 38 kg/m.sup>2. All patients were treated 18 m.nths after their bariatric surgery. All patients underwent an abdom.noplasty as a body contouring procedure. 4 (26.7%) patients presented com.lications related to the surgery. Conclusion: We described a com.rehensive and system.tic approach to m.ssive weight loss for m.le patients, suggesting an abdom.nal m.rking based on the patient’s clinical features and the expected results avoiding fem.nization of the abdom.nal body contour.

Background: Kangaroo m.ther Care is a sim.le safe m.thod used to care for low-birth-weight babies. Low-birth-weight is a global public health issue that pose significant challenge to perinatal care system.. Globally, com.lications due to low-birth-weight are the leading cause of neonatal m.rtality, resulting in an estim.ted 1 m.llion deaths annually. Kangaroo m.ther Care (Km.) is a low-cost m.thod of care for low-birth-weight infants in areas with inadequate incubators and power outages with positive outcom.s. Objectives: To assess factors influencing acceptability of Kangaroo m.ther Care (Km.) in NICU at Arthur Davison Children’s Hospital in Ndola, Zam.ia. m.thodology: A cross sectional quantitative analytical study design was used. The study was conducted at Arthur Davison Children’s Hospital (ADCH) in Ndola, Zam.ia. The purposive sam.ling m.thod was used to select the study participants and a total of 129 m.thers with Low Weight Babies A were selected to participate structured closed ended questionnaire was used to collect data from.the participants using an interview. Data was analyzed using a Statistical Package for Social Scientists (SPSS) software version 26. Cross tabulations were done to determ.ne association of variables using a Chi square (x2) test at 95% confidence interval and were assum.tions where not m.t, fishers exact test was used. m.ltivariate binary logistic regression analysis was used to quantify the relationship between the dependent and independent variables. Results: m.st of the respondents had m.le babies 77%, 69% of the babies weighed 1000 g - 1400 g, m.jority 79% had norm.l delivery, 71% of the respondents were m.ltigravida and m.st of the respondents 79% were m.rried.
