ABSTRACT

BACKGROUND AND AIMS: Ukraine's Ministry of Health released urgent COVID-19 guidelines, allowing for early implementation of take-home dosing (THD) for opioid agonist therapies (OAT) such as methadone. Enrollment in OAT and retention in the program are the most effective HIV prevention strategies for people who inject drugs (PWID). This study aimed to evaluate the impact of Ukraine's COVID-19 emergency guidance on OAT treatment enrollment, retention on treatment and mortality. DESIGN AND SETTING: Using Ukraine's national OAT registry for 252 governmental clinics across 25 regions, we conducted a 12-month comparative prospective cohort survival analysis. This study compared newly enrolled methadone patients within the initial 6 months following the COVID-19 guidance (COVID) with patients from the preceding year (pre-COVID) in a country with high adult HIV prevalence (1.2%) that is concentrated in PWID. PARTICIPANTS: In the nation-wide sample of newly enrolled PWID in Ukraine, comprising 2798 individuals, 1423 were in the COVID cohort and 1375 were in the pre-COVID cohort. The majority were male (86.7%), with an average age of 39.3 years. MEASUREMENTS: Primary outcomes were average monthly enrollment per cohort, treatment retention and mortality, with internal time-dependent predictors, including THD and optimal (> 85 mg) methadone dosing. RESULTS: Relative to the pre-COVID period, the monthly average patient enrollment was statistically significantly higher during the COVID period (283.7 versus 236.0; P < 0.0001), where patients were more likely to transition to THD and achieve optimal dosing earlier. Significant differences were observed in the proportions of person-months on THD (41 versus 13%, P < 0.0001) and optimal dosing (38 versus 31%, P < 0.0001) between the COVID and pre-COVID cohorts. Predictors of treatment retention, expressed as adjusted hazard ratios (aHR), included early THD [aHR = 1.90, 95% confidence interval (CI) = 1.47-2.45], early optimal dosing (aHR = 1.71, 95% CI = 1.37-2.13) and prior methadone treatment (aHR = 1.39, 95% CI = 1.15-1.68). These factors persisted, respectively, in the pre-COVID (aHR = 2.28, 95% CI = 1.41-3.70; aHR = 1.84, 95% CI = 1.32-2.56; and aHR = 1.36, 95% CI = 1.06-1.74) and COVID (aHR = 1.91, 95% CI = 1.40-2.59; aHR = 1.61, 95% CI = 1.20-2.16; and aHR = 1.49, 95% CI = 1.08-1.94) cohorts. Survival did not differ significantly between the two prospective cohorts. CONCLUSION: Ukraine's prompt adoption of early take-home dosing for opioid agonist therapies, such as methadone, following the emergency COVID-19 guidance appears to have increased enrollment into methadone and improved treatment retention for people who inject drugs without adverse effects on patient survival.

ABSTRACT

BACKGROUND: The prevalence of obesity-related cardiometabolic disease in Samoa is among the highest globally. While physical activity is a modifiable risk factor for obesity-related disease, little is known about physical activity levels among adult Samoans. Using wrist-worn accelerometer-based devices, this study aimed to characterize physical activity among Samoan adults. METHODS: Samoan adults (n = 385; 55% female, mean [SD] age 52 [10] y) wore Actigraph GT3X+ devices for 7 to 10 days. General linear models were used to examine mean daily minutes of sedentary time, light physical activity, and moderate to vigorous physical activity by various participant characteristics. RESULTS: Time spent in moderate to vigorous physical activity did not differ statistically between men (88 [5] min; 95% confidence interval [CI], 80-97) and women (78 [4] min; 95% CI, 70-86; P = .08). Women, however, spent more time than men in light physical activity: 380 (7) minutes (95% CI, 367-393) versus 344 (7) minutes (95% CI, 329-358; P < .001). While there were no differences in physical activity by census region, education, or occupation among women, men in urban areas spent significantly less time in moderate to vigorous physical activity than those in peri-urban and rural areas (P = .015). Women with class II/III obesity spent more time in sedentary activities than those with healthy weight or overweight/class I obesity (P = .048). CONCLUSIONS: This study characterizes physical activity among Samoan adults and highlights variation by sex, urbanicity, and weight status. In providing initial device-measured estimates of physical activity in Samoa, this analysis establishes a baseline from which the success of future attempts to intervene on physical activity may be assessed.

ABSTRACT

Aim: A systematic review and meta-analysis were performed to evaluate the efficacy of treatments for previously treated advanced biliary tract cancer (BTC) patients. Materials & methods: Databases were searched for studies evaluating treatments for advanced (unresectable and/or metastatic) BTC patients who progressed on prior therapy. Pooled estimates of objective response rate (ORR), median overall survival (OS) and median progression-free survival (PFS) were calculated using random effects meta-analysis. Results: Across 31 studies evaluating chemotherapy or targeted treatment regimens in an unselected advanced BTC patient population, pooled ORR was 6.9%, median OS was 6.6 months and median PFS was 3.2 months. Conclusion: The efficacy of conventional treatments for previously treated advanced BTC patients is poor and could be improved by novel therapies.


What is this article about? Most patients with biliary tract cancer are identified with advanced disease, and almost all go through a worsening of the disease after their first treatment. For patients who go on to receive their next treatment, current guidelines are unclear regarding the best treatment choice. Therefore, we examined the available medical literature and performed an analysis of multiple studies to calculate overall estimates of the clinical value of standard treatments for these patients. Our goal was to develop a benchmark against which to compare the clinical value of new treatments that are currently being assessed in clinical trials. What were the results? We identified 31 studies assessing standard treatments (involving chemotherapy or molecularly targeted treatments) in previously treated advanced biliary tract cancer patients. Across these studies, the objective tumor response rate was 6.9%, median overall survival was 6.6 months and median progression-free survival was 3.2 months. What do the results of the study mean? These results indicate that there is limited clinical value of standard treatments for patients with advanced biliary tract cancer whose disease worsened after first treatment. This medical need could potentially be met by new treatments, such as immunotherapies that restore the immune system's ability to attack cancer cells and thereby prolong patient survival.

ABSTRACT

OBJECTIVE: Examine the association between sex, race, ethnicity, and family income, and the intersectionality between these identities, and sustained or cultivated paths in surgery in medical school. METHODS: This retrospective cohort study examines US medical students who matriculated in academic years 2014-2015 and 2015-2016. Data were provided by the Association of American Medical Colleges, including self-reported sex, race, ethnicity, family income, interest in surgery at matriculation, and successful placement into a surgical residency at graduation. This study examined 2 outcomes: (1) sustained path in surgery between matriculation and graduation for students who entered medical school with an interest in surgery and (2) cultivated path in surgery for students who entered medical school not initially interested in surgery and who applied to and were successfully placed into a surgical residency at graduation. RESULTS: Among the 5074 students who reported interest in surgery at matriculation, 2108 (41.5%) had sustained path in surgery. Compared to male students, female students were significantly less likely to have sustained path in surgery [adjusted relative risk (aRR): 0.92 (0.85-0.98)], while Asian (aRR: 0.82, 95% CI: 0.74-0.91), Hispanic (aRR: 0.70, 95% CI: 0.59-0.83), and low-income (aRR: 0.85, 95% CI: 0.78-0.92) students were less likely to have a sustained path in surgery compared to their peers. Among the 17,586 students who reported an initial interest in a nonsurgical specialty, 1869 (10.6%) were placed into a surgical residency at graduation. Female students, regardless of race/ethnic identity and income, were significantly less likely to have cultivated paths in surgery compared to male students, with underrepresented in medicine female students reporting the lowest rates. CONCLUSIONS AND RELEVANCE: This study demonstrates the significant disparity in sustained and cultivated paths in surgery during undergraduate medical education. Innovative transformation of the surgical learning environment to promote surgical identity development and belonging for females, underrepresented in medicine, and low-income students is essential to diversify the surgical workforce.

ABSTRACT

BACKGROUND: Among gay, bisexual, and other men who have sex with men (GBM), sexual orientation disclosure to social groups can act as a significant risk for depression. The primary goal of this research is to understand the association between disclosure and depression, the association of social support and intimate partner violence (IPV) experiences, depression, and disclosure. METHODS: This project uses a secondary dataset of Thailand from a larger cross-sectional study distributed in the Greater Mekong Sub-Region. This study utilized web-based answers from 1468 Thai GBM respondents between the ages of 15-24 years. RESULTS: Prevalence of depression was over 50%. Across the social groups of interest, those who disclosed to everyone had the lowest depression prevalence. This association was statistically significant for all groups (p<0.050) except for "Family members" (p = 0.052). There was a statistically significant association illustrated between full disclosure to social groups and increased social support. Most respondents (43.9%) had low social support, and additionally this group had the highest level of depression, compared to those with high social support. There was a statistically significant association for lowered depression outcomes and increased social support. IPV experiences that occurred within the last six months had a statistically significant relationship with depression (p = 0.002). There was a notable association between those with experiences of being a victim of IPV, alone and in conjunction with experience of being a perpetrator of IPV, which was associated with increased odds of depression. However, the type of IPV experiences an individual had did not differ based on disclosure status. DISCUSSION: This study provides strengthened evidence of the impact that differences in supportive networks can have on mental health outcomes. In addition, they provided a wider consideration for how people may have different IPV experiences, either as a perpetrator, victim, or both, and how those shapes health outcomes of depression. GBM communities still face adversity and challenges that affect their long-term health outcomes, even if they do live in what is considered an accepting country.

ABSTRACT

PURPOSE: This study examined the impact of patient race/ethnicity on the likelihood of experiencing delays to surgery, post-operative surgical complications, and prolonged hospital length of stay (LOS) following primary cleft lip (CL) repair. METHODS: Patients who underwent CL repair were identified in the 2006-2012 Kids' Inpatient Database. Primary outcomes were defined as treatment after 6-months-old, presence of any surgical complication, LOS >1 day, and total hospital charges. Multivariable analyses were performed to adjust for sociodemographic and clinical characteristics that might account for differences in outcomes. RESULTS: There were 5927 eligible patients with cleft lip: 3724 White, 279 Black, 1316 Hispanic, 277 Asian/Pacific-Islander, and 331 other race/ethnicity. Across all outcomes, there were significant unadjusted differences (p<0.001) by race/ethnicity, with White children having the lowest odds of delayed surgery, complications, and prolonged LOS, and the lowest charges. Multivariable analyses suggested that differences in baseline health status may account for much of this disparity in combination with factors such as income, insurance type, and location. Even after adjusting for co-variates, significantly increased odds of delayed surgery and higher charges remained for Hispanic and Asian/PI patients. CONCLUSION: There are significant differences in the odds of delays, complications, prolonged hospital stays, and total charges among CL patients of different race/ethnicity. Advocacy efforts to ameliorate disparity in early infant health may subsequently improve equity in cleft outcomes.

ABSTRACT

The effects of COVID-19-associated restrictions on youth sexual and reproductive health (SRH) care during the pandemic remain unclear, particularly in sub-Saharan Africa. This study uses interrupted time series analyses to assess changes in SRH care utilisation (including visits for HIV testing and treatment, family planning, and antenatal care) adolescent girls' and young women's (AGYW; aged 15-24 years old) in eSwatini following COVID-19 lockdown beginning in March 2020. SRH utilisation data from 32 clinics in the Manzini region that remained open throughout the 2020 COVID-19 period were extracted from eSwatini's electronic health record system. We tabulated and graphed monthly visits (both overall and by visit type) by AGYW during the two-year period between January 2019 and December 2020. Despite the March to September 2020 lockdown, we did not detect significant changes in monthly visit trends from 2019 to 2020. Our findings suggest little change to AGYW's SRH utilisation in eSwatini during the 2020 COVID-19 lockdown period.

ABSTRACT

PURPOSE: Evaluating whether patient populations in clinico-genomic oncology databases are comparable with whom in other databases without genomic component is important. METHODS: Four databases were compared for colorectal cancer (CRC) cases and stage IV CRC cases: American Association for Cancer Research Project Genomics Evidence Neoplasia Information Exchange Biopharma Collaborative (GENIE-BPC), The Cancer Genome Atlas (TCGA), SEER-Medicare, and MarketScan Commercial and Medicare Supplemental claims databases. These databases were also compared with the SEER registry database which serves as national benchmarks. Demographics, clinical characteristics, and overall survival were compared in patients with newly diagnosed CRC and patients with stage IV CRC across databases. Treatment patterns were further compared in patients with stage IV CRC. RESULTS: A total of 65,976 patients with CRC and 13,985 patients with stage IV CRC were identified. GENIE-BPC had the youngest patient population (mean age [years]: CRC, 54.1; stage IV CRC, 52.7). SEER-Medicare had the oldest patient population (CRC, 77.7; stage IV CRC, 77.3). Most patients were male and of White race across databases. GENIE-BPC had the highest proportion of patients with stage IV CRC (48.4% v other databases 13.8%-25.4%) and patients receiving treatments (95.7% v 37.6%-59.1%). Infusional fluorouracil, leucovorin, and oxaliplatin with or without bevacizumab was the most common regimen across databases accounting for 47.3%-78.5% of patients receiving first line of therapy. The median survival from diagnosis was 36, 94, 44 months (CRC) and 23, 36, 15 months (stage IV CRC) for patients in GENIE-BPC after left truncation, TCGA, and SEER-Medicare databases, respectively. CONCLUSION: Compared with other databases, GENIE-BPC had the youngest patients with CRC with the most advanced disease and the largest proportion of patients receiving treatment. Investigators should consider adjustments when extrapolating results from clinico-genomic databases to the general CRC population.

ABSTRACT

OBJECTIVE: Inferior vena cava (IVC) atresia is a rare venous anomaly characterized by absence of the IVC. It has been associated with deep vein thrombosis (DVT) and other congenital anomalies. The aim of the present study is to provide a comprehensive summary of the literature on IVC atresia and discuss the presentation and outcomes of patients with IVC atresia. METHODS: A systematic review of the English literature up to April 2020 was performed. The presentations and treatments reported were noted and compared between the two sexes. The IVC atresia cases were further stratified into isolated IVC atresia and IVC atresia associated with other congenital anomalies. RESULTS: A total of 412 abstracts were screened, with 178 reports included. A total of 376 patients were analyzed. Overall, males seem to be more affected than females, with a ratio of almost 2:1 (male, 227 [64.1%]; vs female, 127 [35.8%]). However, females were more likely to have congenital IVC atresia compared with males (46.1% vs 21.3%; P < .001). The mean age at presentation was 27.9 ± 18.0 years (range, 0-77 years), with no differences between the sexes. Most patients with IVC atresia presented with DVT (n = 242 of 376; 64.3%), with the iliac veins most often affected (n = 159 of 242; 65.7%). No difference was found in the reported proportion of patients presenting with DVT between the two sexes. The symptom presentation was similar, with leg pain and swelling the most common in both sexes. The patients were treated either medically with anticoagulation or surgically (open or endovascular). No mortality was reported with isolated IVC atresia in either treatment group. However, the mortality of patients with IVC atresia associated with other congenital anomalies was 11.7%. CONCLUSIONS: IVC atresia is more common in males but seems to have a predilection for females in the setting of other congenital anomalies. Most patients present with leg pain and swelling related to the development of DVT. Open and endovascular surgical interventions to treat IVC atresia have been reported in 18.3% of patients reviewed, with acceptable mid-term results in terms of patency and symptomatic relief.

ABSTRACT

MICRO ABSTRACT: This retrospective observational study assessed real-world treatment patterns and clinical outcomes among first-line MSI-H/dMMR metastatic colorectal cancer patients. Of 150 patients in the study cohort, 38.7% were treated with chemotherapy and 61.3% with chemotherapy + EGFR/VEGF inhibitor (EGFRi/VEGFi). Clinical outcomes were better among patients who received chemotherapy + EGFR/VEGF inhibitor than those who received chemotherapy. INTRODUCTION: Prior to pembrolizumab approval in first-line (1L) treatment of MSI-H/dMMR metastatic colorectal cancer (mCRC), patients were managed with chemotherapy with or without an EGFRi or VEGFi, agnostic of biomarker testing or mutation status. This study assessed real-world treatment patterns and clinical outcomes among 1L MSI-H/dMMR mCRC patients treated with standard of care (SOC). PATIENTS AND METHODS: Retrospective observational evaluation of patients ≥18 years diagnosed with stage IV MSI-H/dMMR mCRC who received community-based oncology care. Eligible patients were identified (01-Jun-2017 - 29-Feb-2020) and followed longitudinally until 31-Aug-2020/the last patient record/date of death. Descriptive statistics and Kaplan-Meier analyses were conducted. RESULTS: Of 150 1L MSI-H/dMMR mCRC patients, 38.7% were treated with chemotherapy and 61.3% with chemotherapy + EGFRi/VEGFi. Accounting for censoring, the overall median real-world time to treatment discontinuation (95% CI) was 5.3 (4.4, 5.8) months; 3.0 (2.1, 4.4) and 6.2 (5.5, 7.6) months in the chemotherapy and chemotherapy + EGFRi/VEGFi cohorts, respectively. The combined median overall survival was 27.7 (23.2, not reached [NR]) months; 25.3 (14.5, NR) and 29.8 (23.2, NR) months in the chemotherapy and chemotherapy + EGFRi/VEGFi cohorts, respectively. The overall median real-world progression-free survival was 6.8 (5.3, 7.8) months; 4.2 (2.8, 6.1) and 7.7 (6.1, 10.2) months in the chemotherapy and chemotherapy + EGFRi/VEGFi cohorts, respectively. CONCLUSIONS: 1L MSI-H/dMMR mCRC patients receiving chemotherapy with EGFRi/VEGFi had better outcomes than those receiving only chemotherapy. An unmet need and opportunity to improve outcomes exists in this population that may be addressed by newer treatments like immunotherapies.

ABSTRACT

PURPOSE: Although second-line treatments improve survival compared to best supportive care in patients with advanced gastric cancer with disease progression on first-line therapy, prognosis remains poor. A systematic review and meta-analysis were conducted to quantify the efficacy of second-or-later line systemic therapies in this target population. METHODS: A systematic literature review (January 1, 2000 to July 6, 2021) of Embase, MEDLINE, and CENTRAL with additional searches of 2019-2021 annual ASCO and ESMO conferences was conducted to identify studies in the target population. A random-effects meta-analysis was performed among studies involving chemotherapies and targeted therapies relevant in treatment guidelines and HTA activities. Outcomes of interest were objective response rate (ORR), overall survival (OS), and progression-free survival (PFS) presented as Kaplan-Meier data. Randomized controlled trials reporting any of the outcomes of interest were included. For OS and PFS, individual patient-level data were reconstructed from published Kaplan-Meier curves. RESULTS: Forty-four trials were eligible for the analysis. Pooled ORR (42 trials; 77 treatment arms; 7256 participants) was 15.0% (95% confidence interval (CI) 12.7-17.5%). Median OS from the pooled analysis (34 trials; 64 treatment arms; 60,350 person-months) was 7.9 months (95% CI 7.4-8.5). Median PFS from the pooled analysis (32 trials; 61 treatment arms; 28,860 person-months) was 3.5 months (95% CI 3.2-3.7). CONCLUSION: Our study confirms poor prognosis among patients with advanced gastric cancer, following disease progression on first-line therapy. Despite the approved, recommended, and experimental systemic treatments available, there is still an unmet need for novel interventions for this indication.

ABSTRACT

Background: In the recent years, there has been a rapid increase in the use of robot assisted neck dissection (RAND) as an alternative method for conventional neck dissection. Several recent reports have emphasized upon the feasibility and effectiveness of this technique. However, substantial technical and technological innovation is still essential in spite of the availability of multiple approaches for RAND. Materials and Methods: The present study describes a novel technique, i.e., Robotic Infraclavicular Approach for Minimally Invasive Neck Dissection (RIA MIND) used in head and neck cancers with the help of Intuitive da Vinci Xi Surgical System. Results: After RIA MIND procedure, the patient was discharged on the third post operative day. Also, the total wound size was less than 3.5 cm which enhanced the patient recovery time and required minimal post operative care. The patient was further reviewed 10 days after the procedure for the removal of sutures. Conclusion: RIA MIND technique was effective and safe for performing neck dissection for oral, head and neck cancers. However, additional detailed studies will be required for establishing this technique.

ABSTRACT

Wound healing is a complex and dynamic physiological process consisting of a series of cellular and molecular events that initiate immediately after a tissue lesion, to reconstruct the skin layer. It is indubitable that patients with chronic wounds, severely infected wounds, or any metabolic disorder of the wound microenvironment always endure severe pain and discomfort that affect their quality of life. It is essential to treat chronic wounds for conserving the physical as well as mental well-being of affected patients and for convalescing to improve their quality of life. For supporting and augmenting the healing process, the selection of pertinent wound dressing is essential. A substantial reduction in healing duration, disability, associated cost, and risk of recurrent infections can be achieved via engineering wound dressings. Hydrogels play a leading role in the path of engineering ideal wound dressings. Hydrogels, comprising water to a large extent, providing a moist environment, being comfortable to patients, and having biocompatible and biodegradable properties, have found their success as suitable wound dressings in the market. The exploitation of hydrogels is increasing perpetually after substantiation of their broader therapeutic actions owing to their resemblance to dermal tissues, their capability to stimulate partial skin regeneration, and their ability to incorporate therapeutic moieties promoting wound healing. This review entails properties of hydrogel supporting wound healing, types of hydrogels, cross-linking mechanisms, design considerations, and formulation strategies of hydrogel engineering. Various categories of hydrogel wound dressing fabricated recently are discussed based on their gel network composition, degradability, and physical and chemical cross-linking mechanisms, which provide an outlook regarding the importance of tailoring the physicochemical properties of hydrogels. The examples of marketed hydrogel wound dressings are also incorporated along with the future perspectives and challenges associated with them.

ABSTRACT

Despite being potent, the marketed formulations of Docetaxel (DX) are associated with numerous side effects and are meant for intravenous administration. Advanced pharmaceutical nanotechnology has a significant potential to facilitate the 'intravenous (i.v) to oral switch'. The present research work deals with the development of an orally administrable, folate-receptor-targeted Nanostructured lipid carriers (NLCs) of DX (FA-DX-NLCs) for facilitating oral chemotherapy of lung cancer while overcoming the bioavailability and toxicity issues. The nanoformulation prepared to employ high-pressure homogenization and lyophilization, was evaluated and statistically analyzed for various in-vitro and in-vivo formulation characteristics. The lyophilized nanoparticles were observed to be spherical with a particle size of 183.4 ± 2.13 (D90), Pdi of 0.358 ± 0.03, % EE of 82.41 ± 2.44, % DL of 4.41 ± 0.54 and a zeta potential of -3.3 ± 0.7 mv. The increased oral in-vivo bioavailability of DX was evident from the plasma-concentration area under the time curve (AUC0-t), which was âˆ¼ 27-fold greater for FA-DX-NLCs as compared to DX suspension. The orally administered FA-DX-NLCs exhibited excellent antitumor efficacy in a pre-clinical model of lung carcinoma. Tumor staging, histopathology, and immunostaining of the tumors suggested greater anti-proliferative, apoptotic, anti-metastatic, and anti-angiogenic potential as compared to DX-suspension. The pre-clinical toxicity studies affirmed the excellent safety and bio-compatibility of FA-DX-NLCs.

ABSTRACT

South Asians face stressors as a growing immigrant group in America. Work is needed to understand how these stressors impact mental health to identify those at risk of depression and design interventions. This study examined associations of three stressors (discrimination, low social support, limited English proficiency) with depressive symptoms in South Asians. Using cross-sectional data from the Mediators of Atherosclerosis in South Asians Living in America study (N = 887), we fit logistic regression models to evaluate independent/joint effects of three stressors on depression. Overall prevalence of depression was 14.8%; 69.2% of those with all three stressors had depression. The combined effect of high discrimination/low social support was significantly greater than the sum of the individual factors. Experiences of discrimination, low social support, or limited English proficiency, as well as a combination of these factors, should be considered when diagnosing/treating South Asian immigrants in a culturally appropriate manner.
