RESUMEN

Out-of-school adolescent girls/young women (AGYW) in Africa are at increased risk for HIV and are underserved by HIV prevention interventions. Identifying social networks of out-of-school AGYW may be a strategic approach for reaching them. A sequential mixed methods study design was used. The PLACE (Priorities for Local AIDS Control Efforts) methodology, implemented in one ward of Dar es Salaam, Tanzania, identified 69 networks of AGYW. We randomly selected 28 networks and conducted surveys and network assessments with 80.9% (n = 310) of the members. On average, the networks consisted of 13.7 members, and had a density of 0.65 and a transitivity of 0.80, indicating high cohesion. The networks were mostly female (92%). On average, 67% of network membership were AGYW aged 15-24 years, of whom 70% were out-of-school and 67% were sexually active. Among sexually active AGYW aged 15-24, self-reported HIV seropositivity was 12.2%. We then conducted focus group discussions with 6 purposively selected networks. AGYW described their networks as sources of support and advice. Social norms supported AGYW engaging in transactional sex to alleviate life's hardships; it was the easiest way to earn income without "sweating". AGYW discussed IPV as a common experience, and social norms stigmatized AGYWs' use of condoms. AGYW were largely unaware of pre-exposure prophylaxis. The self-reported HIV prevalence rates of this cohort were higher than national averages, suggesting we tapped into high-risk networks. Social norms promoted transactional and unprotected sex. Social networks are an acceptable channel for HIV prevention intervention delivery to out-of-school AGYW.

RESUMEN

Prinsepia utilis, a wild-growing Himalayan shrub, is a good source of phytoceuticals, cosmeceuticals, and antioxidants. The present study is an attempt to investigate the effect of altitude and edaphic factors on phenolics and antioxidant activity in fruit pulp of Prinsepia utilis. The ripened fruits and soil samples were collected for detailed investigation. The fruits (pulp) were extracted in methanol for analyzing total phenolics and antioxidant activity using a spectrophotometric method and phenolic compounds by high-performance liquid chromatography (HPLC). Similarly, standard methods for soil analysis were used. Results reveal that altitude negatively correlated with total phenolics and flavonoid contents determined by a spectrophotometric method and with specific phenolic compounds determined by HPLC. For instance, Dwarahat population (PU-1) at lower altitude (1400 m asl) exhibited higher values of total phenolics and flavonoids, while total tannin was higher at Nainital (PU-6) population (2000 m asl). The antioxidant activity measured by 2, 2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) was found higher in Narayan Ashram (PU-9) population (2750 m asl), while ferric reducing antioxidant power (FRAP) was significantly higher in Badechena (PU-2) population (1600 m asl). Soil nutrients (edaphic factors) showed a good correlation among measured parameters. Neighbor-joining and principal component analysis identified phenolics and antioxidant-rich populations that can be utilized for collection of fruits from these populations.

RESUMEN

BACKGROUND: Intimate partner violence (IPV) and sexually transmitted infections (STIs), including HIV, remain important public health problems with devastating health effects for men and women in sub-Saharan Africa. There have been calls to engage men in prevention efforts, however, we lack effective approaches to reach and engage them. Social network approaches have demonstrated effective and sustained outcomes on changing risk behaviors in the U.S. Our team has identified and engaged naturally occurring social networks comprised mostly of young men in Dar es Salaam in an intervention designed to jointly reduce STI incidence and the perpetration of IPV. These stable networks are locally referred to as "camps." In a pilot study we demonstrated the feasibility and acceptability of a combined microfinance and peer health leadership intervention within these camp-based peer networks. METHODS DESIGN: We are implementing a cluster-randomized trial to evaluate the efficacy of an intervention combining microfinance with health leadership training in 60 camps in Dar es Salaam, Tanzania. Half of the camps have been randomized to the intervention arm, and half to a control arm. The camps in the intervention arm will receive a combined microfinance and health leadership intervention for a period of two years. The camps in the control arm will receive a delayed intervention. We have enrolled 1,258 men across the 60 study camps. Behavioral surveys will be conducted at baseline, 12-months post intervention launch and 30-month post intervention launch and biological samples will be drawn to test for Neisseria gonorrhea (NG), Chlamydia trachomatis (CT), and Trichomonas vaginalis (TV) at baseline and 30-months. The primary endpoints for assessing intervention impact are IPV perpetration and STI incidence. DISCUSSION: This is the first cluster-randomized trial targeting social networks of men in sub-Saharan Africa that jointly addresses HIV and IPV perpetration and has both biological and behavioral endpoints. Effective approaches to engage men in HIV and IPV prevention are needed in low resource, high prevalence settings like Tanzania. If we determine that this approach is effective, we will examine how to adapt and scale up this approach to other urban, sub-Saharan African settings.

RESUMEN

BACKGROUND: Postoperative nausea and vomiting is the most common cause for unexpected hospital admission of patients undergoing day care surgery. Overnight fasting changes patient metabolic state and influences their perioperative stress response. Preoperative carbohydrate loading may have accelerated recovery and better overall outcome after major abdominal surgery. The aim of the study was to investigate the effects of preoperative carbohydrate-rich drinks on postoperative nausea and vomiting and pain after day care laparoscopic cholecystectomy. METHODS: A total of 120 patients posted for day care laparoscopic cholecystectomy were included in the study and were randomized into three groups. Group A (Cases)-receiving the carbohydrate-rich drink before surgery (CHO), group B (placebo)-receiving the placebo drink before surgery and group C (controls)-fasting from midnight before surgery. Postoperative nausea and vomiting and visual analogue score for pain were noted and analyzed for 24 h. RESULTS: Mean score of nausea in 0-4 h in group A was significantly lower as compared to group B and group C (p = 0.001). Difference in mean score of nausea in 4-12 and 12-24 h between groups was not significant (p = 0.066), (p = 0.257). Mean score of vomiting in 0-4 and 4-12 h in group A was significantly less than that of group B and group C (p = 0.004), (p = 0.001). Mean score of pain in group A was significantly less when compared to group B and group C in 0-4 h (p = 0.001) and 4-12 h (0.005). CONCLUSION: Perioperative consumption of a carbohydrate-rich drink can minimize postoperative nausea, vomiting and pain in patients undergoing outpatient cholecystectomy. Consumption of carbohydrate drinks up to 2 h prior to surgery is not associated with additional complications.

RESUMEN

Cyanidin-3-O-galactoside (Cy3-gal) is the most widespread anthocyanin that has been found to be applicable to nutraceutical and pharmaceutical ingredients. Nevertheless, the process of separation and purification, susceptibilities to heat, and pH inactivation present some limitations. In the present study, natural deep eutectic solvents (NADES) with an ultrasonic-assisted extraction method were briefly studied, and the recovery of Cy3-gal from Rhododendron arboreum was highlighted. The NADES, consisting of choline chloride and oxalic acid (1:1), was screened out as an extractant, and single-factor experiments combined with a two-site kinetic model were employed to describe the extraction process. Further, the work investigated ultrasound-assisted adsorption/desorption to efficiently purify Cy3-gal using macroporous resins. The optimal extraction conditions to attain maximum Cy3-gal yield was 30% water in a 50:1 (mL/g) solvent-to-sample ratio, 11.25 W/cm3 acoustic density, and 50% duty cycle for 16 min of extraction time. Under these conditions, the results revealed 23.07 ± 0.14 mg/g of Cy3-gal, two-fold higher than the traditional solvents. Furthermore, of the different resins used, Amberlite XAD-7HP showed significantly (p < 0.05) higher adsorption/desorption capacities (12.82 ± 0.18 mg/g and 10.97 ± 0.173 mg/g) and recovery (48.41 ± 0.76%) percent over other adsorbents. Experiments on the degrading behavior (40-80 °C) of the recovered Cy3-gal were performed over time, and the first-order kinetic model better explained the obtained data. In conclusion, the study asserts the use of ultrasonication with NADES and XAD-7HP resin for the improved purification of Cy3-gal from the crude extract.

RESUMEN

Aim: To describe the case of a patient with Marfan syndrome who had bilateral superonasal lens subluxation. Method: The case of a male patient, aged 18, who complained of having impaired vision in both eyes (BE) since he was a toddler, was presented. On examination of the patient, features suggestive of Marfan syndrome were revealed, as well as bilateral intraocular lens subluxation. Results: The patient was refracted and glasses were recommended, which improved his vision. The patient was referred to the cardiology, orthopedic, and dental departments for a multidisciplinary approach to prevent complications and further management. Discussion: Lens subluxation is frequently presented as a primary clinical manifestation of Marfan syndrome. It can vary from asymptomatic, which is seen only after pupillary dilation, to significant subluxation, in which the equator of the lens in the pupillary axis causes diplopia or decreased vision. Conclusion: This case underscored the importance of considering the rare feature of Marfan syndrome.

RESUMEN

Mahonia jaunsarensis Ahrendt (Family Berberidaceae) an endemic species was successfully propagated in vitro. An efficient propagation protocol has been developed first time. The callus cultures were established from leaf explants on Murashige and Skoog (MS) medium supplemented with 2,4-Dichlorophenoxyacetic acid (2,4-D; 1 µM) and resulted 70% callus induction with green compact callus. When callus was transferred to MS medium containing Thidiazuron (TDZ; 0.75 µM), maximum average number of shoot (3.06) produced but shoot length (3.37 cm) and average leaf number (2.87) was increased upon transfer to MS medium containing N6-benzylaminopurine (BA; 6.0 µM) plus α-naphthalene acetic acid (NAA; 0.5 µM). In MS medium containing indole-3-butyric acid (IBA; 0.01 µM), the maximum rooting percentage (56%) and average root number (2.56) per shoot and root length (3.33 cm) were recorded. The rooted plantlets transferred in vermiculite + garden soil + farmyard manure (1:1:1) with maximum (55%) survival percentage under greenhouse condition. The phytochemical analysis of leaves obtained from tissue culture-raised plants revealed significantly higher levels of alkaloids (berberine and palmatine) than those obtained from wild plants. Similar trends were observed for antioxidant and antimutagenic activities. Results of this study offer a baseline for the conservation and sustainable utilization strategies for M. jaunsarensis.

RESUMEN

Backgrounds/Aims: Postoperative pancreatic fistula is the key worry in the ongoing debate about the safety and effectiveness of total laparoscopic pancreaticoduodenectomy (TLPD). Laparoscopic-assisted pancreaticoduodenectomy (LAPD), a hybrid approach combining laparoscopic resection and anastomosis with a small incision, is an alternative to TLPD. This study compares the short-term outcomes and oncological efficacy of LAPD vs. open pancreaticoduodenectomy (OPD). Methods: A retrospective analysis of data of all patients who underwent LAPD or OPD for periampullary carcinoma at a tertiary care center in Northeast India from July 2019 to August 2023 was done. A total of 30 LAPDs and 30 OPDs were compared after 1:1 propensity score matching. Demographic data, intraoperative and postoperative data (30 days), and pathological data were compared. Results: The study included a total of 93 patients, 30 underwent LAPD and 62 underwent OPD. After propensity score matching, the matched cohort included 30 patients in both groups. The LAPD presented several advantages over the OPD group, including a shorter incision length, reduced postoperative pain, earlier initiation of oral feeding, and shorter hospital stays. LAPD was not found to be inferior to OPD in terms of pancreatic fistula incidence (Grade B, 30.0% vs. 33.3%), achieving R0 resection (100% vs. 93.3%), and the number of lymph nodes harvested (12 vs. 14, p = 0.620). No significant differences in blood loss, short-term complications, pathological outcomes, readmissions, and early (30-day) mortality were observed between the two groups. Conclusions: LAPD has comparable safety, technical feasibility, and short-term oncological efficacy.

RESUMEN

Aim: To report a case of cytomegalovirus (CMV) neuroretinitis observed in an immunocompetent patient. Materials and methods: The patient presented with a complaint of diminution of vision in both eyes (BE) and had a traumatic cataract in the right eye (RE). Fundus examination of the left eye (LE) revealed an active white, fluffy lesion with an overlying retinal hemorrhage patch with a macular star. The diagnosis of CMV neuroretinitis was established, and the patient commenced treatment with valganciclovir. Results: The patient exhibited no underlying risk factors. Subsequently, a positive response to oral valganciclovir treatment was observed. Discussion: Cytomegalovirus (CMV) neuroretinitis is typically associated with immunocompromised individuals, such as those with HIV/AIDS. The patient's presentation with a traumatic cataract in the right eye and a distinctive fundus appearance in the left eye posed a diagnostic challenge. The absence of common risk factors for CMV infection necessitated a thorough examination and consideration of rare infectious etiologies. The positive response to valganciclovir reinforces its efficacy in managing CMV-related ocular conditions. This case emphasized the necessity for ophthalmologists to maintain a high index of suspicion for CMV and other unusual pathogens when faced with neuroretinitis in patients who do not present with typical systemic immunosuppressive conditions. Early diagnosis and appropriate antiviral therapy prevent potential complications and preserve vision in such atypical presentations. Conclusion: This case underscores the importance of considering rare infectious agents in immunocompetent patients when encountering neuroretinitis, particularly in the absence of typical symptoms or signs of the disease.

RESUMEN

This study presents a comprehensive analysis of the methanolic extracts of nine species of wild edible mushrooms (WEM) native to the Darma Valley in the Kumaun Himalaya region. The investigation encompasses the assessment of various biochemical attributes, including total phenolics (TP), total flavonoids (TF), total tannins (TT) contents, the ABTS assay, and the DPPH radical scavenging assay. Among the nine WEM species examined, Clavatia craniiformis stands out for displaying the highest antioxidant capacities, indicated by exceptional TP (54.94 ± 0.54 mg gallic acid equivalenta/g dry weight) and TT (4.23 ± 0.17 mg tannic acid equivalents/g dry weight) contents, along with noteworthy ABTS (10.44 ± 0.34 mg abscorbic acid equivalents/g dw) and DPPH activity (0.335 ± 0.001 mg abscorbic acid equivalents/g dry weight). Subsequent antioxidant potential are mushrooms Ramaria fennica, Ramaria botrytis, Ramaria sanguinea, Ramaria flava, Gomphus. clavatus, Clavaria zollingeri, Pleurotus ostreatus, and Kuehneromyces mutabilis. Variations in antioxidant capacities align with distinct phenolic content. This study underscores as a remarkable source of antioxidants, suggesting its potential suitability for nutraceutical applications. The findings contribute to a deeper understanding of the antioxidant properties inherent in wild edible mushrooms, particularly emphasizing the prominence of C. craniiformis.

RESUMEN

PURPOSE: To compare the visual outcome findings between a new monofocal intraocular lens (IOL) (Tecnis Eyhance) and extended depth of focus (EDOF) IOL (Appasamy Supraphob Infocus). METHODS: This prospective comparative interventional study evaluated 31 patients after implantation of Tecnis Eyhance (15 patients) and Supraphob EDOF IOL (16 patients). The uncorrected and corrected distance and intermediate and near visual acuity were measured at postoperative day 1, 1 week, 4 week, and 3 months. Contrast sensitivity, incidence of halos and glares, and patient satisfaction were assessed at 3 months postoperatively. RESULTS: The Tecnis Eyhance (n = 15) and Supraphob EDOF (n = 16) group were comparable with respect to all preoperative parameters including biometry, visual acuity, and cataract status. The average age distribution of participants was 56 ± 6 years. Postoperatively, both groups had similar distance and intermediate vision, but the near vision was significantly better in the EDOF group (P < 0.01) as compared to Tecnis Eyhance at 3 months. The contrast sensitivity and patient satisfaction were similar in both the groups. The incidence of halos and glares was present in the EDOF group, but it was statistically insignificant. CONCLUSION: The Tecnis Eyhance and Supraphob EDOF both were effective in improving distance and intermediate vision, but the near vision was significantly better in the EDOF group. Both the groups retained good contrast sensitivity and the majority of patients were satisfied.

RESUMEN

Forty-five adults with type IV-A choledochal cysts (CDC) who underwent extrahepatic cyst excision from January 2013 to December 2021 were followed up for a median interval of 25 months (range, 2 to 10 years) to observe the long-term complications in the remaining intrahepatic cyst. Late complications in varying combinations were seen in 10 patients, which included cholangitis and/or intrahepatic stones in 9 patients, intrahepatic bile duct stenosis with stones in 2 patients, anastomotic stricture in 6 patients, and left lobar atrophy with intrahepatic stones in 3 patients. Out of 6 patients who required re-do hepaticojejunostomy (HJ), three patients had left lobe atrophy with patent HJ anastomosis and a recurrent attack of cholangitis on follow-up at 3, 8, and 10 years. Complications occur frequently after extrahepatic cyst excision for type IV-A CDC and require a long-term follow-up.

RESUMEN

Aim: Process evaluations for social and behavioral interventions are increasingly important as interventions become more complex and multi-faceted. Conducting process evaluations in low-resource international settings can be challenging. Process evaluations in low-resource international settings can help inform and improve quality of ongoing intervention implementation. We conducted a process evaluation of a cluster-randomized controlled trial to assess the efficacy of a microfinance and health leadership program on sexually transmitted infections and intimate partner violence perpetration among young men in Tanzania. Subject and Methods: Our trial included 1,491 participants and the intervention lasted two years. We collected process data on microfinance loan uptake and repayment, and health leaders' health conversations with peers to monitor intervention reach and dose received. We developed a database system that allowed offline data collection and synced to a central database when internet was accessible. Research staff in the U.S. accessed data from the central database to analyze and create regular implementation reports. Results: Process graphical reports facilitated identification of implementation challenges and enabled us to resolve issues before they worsened. For example, from a group with low microfinance loan repayment we learned area participants perceived the loan to be a grant, and then we clarified the misinformation with participants. Conclusions: The process evaluation helped inform ongoing intervention implementation, including approaches to improve reach and uptake of interventions. Field staff time was protected by systemizing the sharing of data processing and analyses across the global team.

RESUMEN

Introduction Abdominal aortic aneurysms (AAA) are uncommon in young adults ≤55 years of age. There is a lack of literature on clinical characteristics, risk factors, and therapeutic outcomes so we present a case series of 11 patients of AAA aged ≤55 years. Methods We included single-center retrospective case series between 2013 to 2020. We reviewed 44 patients who were operated for AAA in a tertiary care center in India. We identified 13 patients who were ≤55 years; two patients with incomplete records were excluded. A patient information sheet was used to retrieve demographic data, clinical presentation, outcomes, and follow-up. Results Out of 11 patients, 10 were men. Nine patients (81.8%) had symptomatic AAA. The majority (45.4%) exhibited an infrarenal aneurysm and the median size of the aneurysm was 5.8 cm (IQR: 5.5-6.4 cm). Eight patients (72.7%) had a history of smoking. Hypertension was observed in six patients and one patient had associated coronary artery disease. Clamping time was > 45 minutes among three patients; all smokers. Blood loss was > 500 ml in five patients. The median length of hospital stay was 10 days (7-40); more among patients with metabolic equivalents (METS) score < 4, 14.5 (8-19) days. No grade III-IV complications and mortality were noted with a median follow-up of 15 months, with all patients living. Conclusion The aneurysm was symptomatic in the majority of participants. An association of smoking in increasing both the median clamping time and length of hospital stay was seen. No mortality and good disease-free follow-up suggested good outcomes.

RESUMEN

Aeration experiments, maintaining nappe flow conditions, were carried out on a rectangular stepped cascade of total height 3.0 m to determine the total number of steps, slope of the entire cascade and hydraulic loading rate at which maximum overall aeration efficiency occurs, keeping the surface area of individual steps constant. Based on dimensional analysis, the overall aeration efficiency at standard conditions (E(20)) was expressed as a function of square of total number of steps (N(2)) and dimensionless discharge (d(c)/h), where d(c) and h represent critical depth in a rectangular prismatic channel and individual step height respectively. An empirical equation with E(20) as the response and N(2) and d(c)/h as the independent parameters was developed based on the experimental results subject to 36

RESUMEN

Despite calls to engage men in HIV and intimate partner violence (IPV) prevention efforts, effective approaches to reach and engage men in low-resource, high-HIV prevalence settings are limited. We identified and engaged social networks of mostly young men in a study designed to evaluate the efficacy of a combined microfinance and peer health leadership intervention to prevent HIV and IPV. We conducted a cluster-randomized trial among 60 social networks locally referred to as "camps" within Dar es Salaam, Tanzania. Camps were randomly assigned (1:1) to a microfinance and peer health leadership intervention or a control condition that received a brief delayed intervention after the study's conclusion. Allocation was not masked to participants or researchers. Behavioral assessments were conducted at baseline and 30-months post-intervention launch, with biological samples drawn at 30-months to test for sexually-transmitted infections (STIs). Primary outcomes included prevalence of STIs and past-year IPV perpetration. Secondary outcomes included STI sexual risk behaviors and past-year HIV testing. Proximal intervention targets included inequitable gender norm attitudes and hope. A modified Poisson regression approach was used to estimate intention-to-treat intervention effects on outcomes assessed at the 30-month follow-up. We enrolled 1,258 men within 60 camps. Of these men, 1,029 (81.8%) completed the 30-month follow-up. There were no differences by condition in STI prevalence, IPV perpetration, or sexual risk behaviors at the 30-month follow-up. Intervention participants reported greater levels of past-year HIV testing, controlling for baseline testing (aRR 1.13 95% CI 1.005-1.28). They also reported significantly lower levels of inequitable gender norm attitudes (adjusted effect -0.11, 95% CI -0.21-0.003). We successfully engaged and retained social networks of men in this multilevel intervention study. While we did not see an effect on the primary outcomes, our intervention successfully improved HIV testing and reduced inequitable gender norm attitudes.

RESUMEN

Strangulation of groin hernia can result in significant morbidity and mortality. Spontaneous external fistulation following strangulation is rare and typically occurs with Richter's hernia. Spreading Necrotizing Soft Tissue Infection (NSTI) secondary to Enterocutaneous Fistula (ECF) is an ominous sign, further worsening its prognosis. Early diagnosis and prompt surgical treatment is crucial to improve outcome. Herewith the authors are presenting a case of neglected inguinal hernia. It was complicated with ECF formation and rapidly spreading NSTI of flank. He underwent resection and anastomosis of the gangrenous bowel, anatomical repair of the hernia along with soft tissue debridement of flank region. This patient however succumbed to sepsis with multi organ dysfunction. Significant delay in seeking medical care led to dismal outcome.

RESUMEN

HIV related stigma and discrimination is a known barrier for HIV prevention and care. We aimed to assess the relationship between socio-economic status (SES) and HIV related stigma in Zimbabwe. This paper uses data from Project Accept, which examined the impact of community-based voluntary counseling and testing intervention on HIV incidence and stigma. Total of 2522 eligible participants responded to a psychometric assessment tool, which assessed HIV related stigma and discrimination attitudes on 4 point Likert scale. The tool measured three components of HIV-related stigma: shame, blame and social isolation, perceived discrimination, and equity. Participants' ownership of basic assets was used to assess the socio-economic status. Shame, blame and social isolation component of HIV related stigma was found to be significantly associated with medium [odds ratio (OR)=1.73, P<0.01] and low SES (OR=1.97, P<0.01), indicating more stigmatizing attitudes by participants belonging to medium and low SES in comparison to high SES. For HIV related stigma and discrimination programs to be effective, they should take into account the socio-economic context of target population.
