RESUMO
Uncontrolled fires place considerable burdens on forest ecosystems, compromising our ability to meet conservation and restoration goals. A poor understanding of the impacts of fire on ecosystems and their biodiversity exacerbates this challenge, particularly in tropical regions where few studies have applied consistent analytical techniques to examine a broad range of ecological impacts over multiyear time frames. We compiled 16 y of data on ecosystem properties (17 variables) and biodiversity (21 variables) from a tropical peatland in Indonesia to assess fire impacts and infer the potential for recovery. Burned forest experienced altered structural and microclimatic conditions, resulting in a proliferation of nonforest vegetation and erosion of forest ecosystem properties and biodiversity. Compared to unburned forest, habitat structure, tree density, and canopy cover deteriorated by 58 to 98%, while declines in species diversity and abundance were most pronounced for trees, damselflies, and butterflies, particularly for forest specialist species. Tracking ecosystem property and biodiversity datasets over time revealed most to be sensitive to recurrent high-intensity fires within the wider landscape. These megafires immediately compromised water quality and tree reproductive phenology, crashing commercially valuable fish populations within 3 mo and driving a gradual decline in threatened vertebrates over 9 mo. Burned forest remained structurally compromised long after a burn event, but vegetation showed some signs of recovery over a 12-y period. Our findings demonstrate that, if left uncontrolled, fire may be a pervasive threat to the ecological functioning of tropical forests, underscoring the importance of fire prevention and long-term restoration efforts, as exemplified in Indonesia.

BACKGROUND: The choice of midurethral sling type may impact efficacy and complications in women undergoing transvaginal native tissue repair of pelvic organ prolapse. OBJECTIVE: The primary aim was to determine if the single-incision sling is noninferior to retropubic sling for the management of stress urinary incontinence among patients undergoing reconstructive or obliterative native tissue vaginal repair. The secondary aims were to compare adverse events and surgeon ease of use with sling assignment. STUDY DESIGN: A multicenter, noninferiority, randomized trial of women with ≥ stage II pelvic organ prolapse and objectively confirmed stress urinary incontinence undergoing reconstructive or obliterative vaginal repair was performed. Women were randomized to concomitant single-incision (Altis sling, Coloplast Minneapolis, MN) with suprapubic sham incisions or retropubic slings. The primary dichotomous outcome was abnormal lower urinary tract function within 12 months postsurgery, defined as bothersome stress urinary incontinence symptoms (>1 Pelvic Floor Distress Inventory question no. 17); retreatment for stress urinary incontinence or treatment for urinary retention. Secondary outcomes were adverse events, Patient Global Impression of Improvement of bladder function, and surgeon ease of use (1, worst; 10, best). All subjects completed validated questionnaires and underwent a Pelvic Organ Prolapse Quantification, cough stress test, and postvoid residual preoperatively, at 6 weeks and 12 months postoperatively. Assuming a subjective cure rate for retropubic of 82%, 80% power, and 1-sided 5% significance level, we estimated that 127 patients in each arm were needed to declare noninferiority of the single-incision sling if the upper bound of the 95% confidence interval for the between-group difference per protocol in abnormal bladder function was <12%. Assuming a 10% loss to follow-up, the total enrollment goal was 280. RESULTS: Between December 2018 and January 2023, 280 subjects were enrolled across 7 sites, and 255 were randomized: 126 were for single-incision, and 129 were for retropubic sling. There were no preoperative or operative characteristic differences between groups. Overall, 81% had reconstructive, and 19% had obliterative native tissue repairs. The primary outcome, abnormal lower urinary tract function at 12 months, occurred in 29 (25%) of single-incision vs 24 (20%) of the retropubic sling group (risk difference, 0.04472 [95% confidence interval, -0.03 to 0.1133]; P=.001 for noninferiority). Bothersome stress urinary incontinence occurred in 20% vs 17% (P=.27) and was retreated in 4% vs 2% (P=.44) of single-incision vs retropubic groups, respectively. Adverse events were reported in 24 (16%) of single-incision vs 14 (9%) of the retropubic group (95% confidence interval, 0.95-3.29; P=.70) and included de novo or worsening urgency incontinence symptoms, urinary tract infection, mesh exposure, need for prolonged catheter drainage, and de novo pain, without differences between groups. Patient Global Impression of Improvement (very satisfied and satisfied) was 71% vs 67% (P=.43), and median surgeon ease of sling use was 8 (7-10) vs 9 (8-10), P=.03 in single-incision vs retropubic, respectively. CONCLUSION: For women undergoing vaginal repair, single-incision was noninferior to retropubic sling for stress urinary incontinence symptoms, and complications, including treatment for urinary retention, did not differ.

There is a longstanding debate about the role of nitrogen (N) vs phosphorus (P) in limiting primary production in lakes and whether co-nutrient limitation should be considered for managing eutrophication. We evaluated nutrient limitation and eutrophication at a subcontinental scale. Using U.S. Environmental Protection Agency National Lakes Assessment data, we assessed broad-scale patterns in nutrient limitation and compared samples of all surveyed lakes and lakes resurveyed in multiple surveys. We found that N correlated more strongly with productivity in the western U.S., while P correlated more strongly in the eastern U.S. The aggregated subcontinental effect suggests the importance of factors like N-deposition, terrestrial vegetation, underlying geology, and land use for understanding drivers of nutrient dynamics in lakes. Our study showed how patterns can aggregate across subcontinental scales yet still demonstrate considerable variation when more deeply examined on an individual lake level. Overall, we found that nutrient limitation is dynamic over space and time, with most lakes being co-limited. The prevalence of co-limitation also increased from 2007 to 2017. Trophic states within each limitation category varied substantially. Our findings underscore the need for combined N and P reductions to mitigate accelerated eutrophication.

INTRODUCTION AND HYPOTHESIS: Women undergoing surgery for apical pelvic organ prolapse have several medically sound options for specific surgical approaches. METHODS: We review the principles of shared decision-making as they pertain to surgery for prolapse. We review the literature supporting the superior sacrocolpopexy as a durable treatment for prolapse and the factors that may differentiate it from other repairs in risk and benefit. RESULTS: We emphasize the importance of collaboration between patients and surgeons in surgical decision-making. CONCLUSION: All medically appropriate patients who desire reconstructive surgery for prolapse should be offered sacrocolpopexy.
RESUMO
INTRODUCTION AND HYPOTHESIS: Sacrocolpopexy is the gold standard for the surgical management of apical prolapse. Over the years, surgical advancements have transformed the procedure from a laparotomy with a hospital stay of several days to a minimally invasive approach with a much shorter hospital stay. One recent innovation has the potential to transform minimally invasive sacrocolpopexy. METHODS: The da Vinci single-port robotic platform has allowed urological procedures to generate improved recovery, pain control, and cosmesis, with no differences in complications rates. RESULTS: Although the data with respect to sacrocolpopexy are more limited owing to the novelty of this application, the results appear to be similar to those of urological procedures such as prostatectomy. CONCLUSIONS: We present our surgical technique for completing single-port robotic sacrocolpopexy, with and without a hysterectomy, as well as a review of the relevant literature.
RESUMO
Khat, a naturally growing stimulant, has seen a significant increase in both consumption and cultivation in eastern Ethiopia. This reliance on khat in the region comes despite its known physiological complications, with users unable to restrict khat use due to its pervasive impact on their livelihood. This qualitative study sought to understand the meaning that those in eastern Ethiopia attribute to khat and explore their firsthand experiences with the substance. In June and July of 2023, six unstructured interviews were conducted among residents of the Haramaya District in Ethiopia. To promote a holistic comprehension of the participants' lived experiences, an interpretative phenomenological analysis approach was employed when collecting and analyzing the data. Participant responses were coded independently from one another by two different researchers identifying superordinate and corresponding subordinate themes. Among the participants, six superordinate themes were captured: economic backbone of the region, market disruption & fluctuation, pesticide use, societal relationships around khat, applications of khat, and access to healthcare. The participants' responses indicated that the normalization of khat use, coupled with the downplaying of its addictive potential, has established a framework where khat consumption is not only allowed but, in some cases, even encouraged. The unique interplay between communal practice and individual preservation creates a cyclical effect of using khat to supplement energy to farm khat and then sell or stimulate further work on their farm. This study illuminates the transitionfrom what was once the traditional or spiritual use of khat, to a more practical use for ensuring economic livelihood.

BACKGROUND: The emergence of COVID-19 precipitated containment policies (e.g., lockdowns, school closures, etc.). These policies disrupted healthcare, potentially eroding gains for Sustainable Development Goals including for neonatal mortality. Our analysis aimed to evaluate indirect effects of COVID-19 containment policies on neonatal admissions and mortality in 67 neonatal units across Kenya, Malawi, Nigeria, and Tanzania between January 2019 and December 2021. METHODS: The Oxford Stringency Index was applied to quantify COVID-19 policy stringency over time for Kenya, Malawi, Nigeria, and Tanzania. Stringency increased markedly between March and April 2020 for these four countries (although less so in Tanzania), therefore defining the point of interruption. We used March as the primary interruption month, with April for sensitivity analysis. Additional sensitivity analysis excluded data for March and April 2020, modelled the index as a continuous exposure, and examined models for each country. To evaluate changes in neonatal admissions and mortality based on this interruption period, a mixed effects segmented regression was applied. The unit of analysis was the neonatal unit (n = 67), with a total of 266,741 neonatal admissions (January 2019 to December 2021). RESULTS: Admission to neonatal units decreased by 15% overall from February to March 2020, with half of the 67 neonatal units showing a decline in admissions. Of the 34 neonatal units with a decline in admissions, 19 (28%) had a significant decrease of ≥ 20%. The month-to-month decrease in admissions was approximately 2% on average from March 2020 to December 2021. Despite the decline in admissions, we found no significant changes in overall inpatient neonatal mortality. The three sensitivity analyses provided consistent findings. CONCLUSION: COVID-19 containment measures had an impact on neonatal admissions, but no significant change in overall inpatient neonatal mortality was detected. Additional qualitative research in these facilities has explored possible reasons. Strengthening healthcare systems to endure unexpected events, such as pandemics, is critical in continuing progress towards achieving Sustainable Development Goals, including reducing neonatal deaths to less than 12 per 1000 live births by 2030.

BACKGROUND: Small and sick newborn care (SSNC) is critical for national neonatal mortality reduction targets by 2030. Investment cases could inform implementation planning and enable coordinated resource mobilisation. We outline development of an investment case for Tanzania to estimate additional financing for scaling up SSNC to 80% of districts as part of health sector strategies to meet the country's targets. METHODS: We followed five steps: (1) reviewed national targets, policies and guidelines; (2) modelled potential health benefits by increased coverage of SSNC using the Lives Saved Tool; (3) estimated setup and running costs using the Neonatal Device Planning and Costing Tool, applying two scenarios: (A) all new neonatal units and devices with optimal staffing, and (B) half new and half modifying, upgrading, or adding resources to existing neonatal units; (4) calculated budget impact and return on investment (ROI) and (5) identified potential financing opportunities. RESULTS: Neonatal mortality rate was forecast to fall from 20 to 13 per 1000 live births with scale-up of SSNC, superseding the government 2025 target of 15, and close to the 2030 Sustainable Development Goal 3.2 target of <12. At 85% endline coverage, estimated cumulative lives saved were 36,600 by 2025 and 80,000 by 2030. Total incremental costs were estimated at US$166 million for scenario A (US$112 million set up and US$54 million for running costs) and US$90 million for scenario B (US$65 million setup and US$25 million for running costs). Setup costs were driven by infrastructure (83%) and running costs by human resources (60%). Cost per capita was US$0.93 and the ROI is estimated to be between US$8-12 for every dollar invested. CONCLUSIONS: ROI for SSNC is higher compared to other health investments, noting many deaths averted followed by full lifespan. This is conservative since disability averted is not included. Budget impact analysis estimated a required 2.3% increase in total government health expenditure per capita from US$40.62 in 2020, which is considered affordable, and the government has already allocated additional funding. Our proposed five-step SSNC investment case has potential for other countries wanting to accelerate progress.

PURPOSE: Peer-assisted learning (PAL) can occur informally as part of a medical programme and complements the formal curriculum. However, little is known about the mechanisms and processes of how informal peer-assisted learning (IPAL) is enacted. MATERIALS AND METHODS: This paper presents data from an ethnographic and semi-structured interview study with Year 1 and 2 undergraduate medical students at a UK university. RESULTS: Peers were observed assisting each other informally: a process that developed as part of the integrated, group-based approach to undergraduate medical education at a UK university. IPAL took place both within and outside of formal teaching sessions and included explanation/clarification of particular points, sharing resources, guiding pronunciation and demonstrating skills. Students placed a high value on IPAL and believed that it was beneficial. When IPAL broke down, this led to negative emotions that presented obstacles to learning, such as resentment. CONCLUSIONS: IPAL is an important part of academic support for medical students, and this work shows both its scope, extending from formal to informal teaching, and how it is enacted. This understanding can help educators situate IPAL within student education.

Healthy ageing is a global priority. Polypharmacy (the use of 5+ medicines) amongst older people is increasing, with over one-third of adults in England, aged 80-89, prescribed at least eight medications. Although sometimes necessary, polypharmacy can be harmful; the risk of harm increases with age and number of medicines prescribed. Medication reviews are recommended as one way of reducing the potential harms of polypharmacy although evidence of clinically significant benefit of medication reviews as currently delivered is limited. What happens in medication reviews in practice is poorly understood. We used a linguistic ethnography approach to explore how medication reviews proceed and what is accomplished during these consultations. We studied 18 video-recorded medication review consultations from three general practices in England. The consultations involved patients aged 65 or older, prescribed 10+ medications ('higher risk' polypharmacy), and primary care clinicians (general practitioner or clinical pharmacist). Video-recordings were gathered as part of a wider ethnographic study investigating practices of polypharmacy in primary care between 2017 and 2021. We conducted microanalysis of consultation data, drawing on our ethnographic knowledge of the organisational, institutional and domestic contexts of polypharmacy to inform our interpretation of these interactions. Consultations were time-consuming and involved lengthy stretches of interactional trouble: non-understandings; misunderstandings; misalignments. These stretches revealed profound uncertainties as to the effectiveness of medicines in the context of multimorbidity and polypharmacy. These uncertainties seeped further into 'troubles talk' concerning patients' existential concerns relating to enduring illness, ageing and mortality. Although these existential concerns were partially articulated, clinicians and patients left such troubles talk unelaborated, unresolved and unfinished. Participants succeeded in smoothing over interactional difficulties and maintaining respectful relationships but often fell short of addressing problematic polypharmacy more directly.

The Da Vinci single port® (SP) robotic platform heralds a new era of minimally invasive surgery (MIS). The primary objective of this study was to assess short-term outcomes in patients undergoing SP robotic hysterectomy with concomitant sacrocolpopexy for pelvic organ prolapse (POP). We performed a retrospective case series at two tertiary care centers between January 2021 and August 2023. Patients with POP electing to undergo SP robotic hysterectomy with concomitant sacrocolpopexy were included. Chart abstraction was used to collect patient demographics and clinical outcomes. Recurrent POP was defined as new bothersome vaginal bulge symptoms and evidence of POP beyond the hymen on postoperative examination. 69 patients were included. Median operative time was 209 min (135-312) and estimated blood loss was 100 mL (20-2000). 1 (1.4%) patient sustained a major vascular injury resulting in laparotomy. Median pain score and morphine equivalents administered in PACU were low at 3 (0-7) and 3.2 (0-27) respectively. At 3 months, 60 (86.9%) patients were seen either in person or via telemedicine for their follow up appointment. 59/60 (98.3%) reported no vaginal bulge symptoms and 50/51 (98.0%) had stage 0 or 1 prolapse on exam. One (1.4%) patient had recurrent prolapse and underwent an additional repair. Postoperative complications included 2 (2.9%) cases of ileus/small bowel obstruction, 1 (1.4%) pelvic hematoma requiring a blood transfusion, and 1 (1.4%) umbilical hernia. The SP robotic platform is a safe and feasible platform for MIS hysterectomy and sacrocolpopexy with good short term anatomic and symptomatic outcomes.

IMPORTANCE: Robot-assisted sacrocolpopexy (SCP) is a commonly performed procedure for the repair of apical pelvic organ prolapse; therefore, novel devices and techniques to improve safety and efficacy of this procedure should be explored. OBJECTIVE: The objective of this study was to assess safety and efficacy of 8-mm trocar site for use of a disposable suture/needle management device (StitchKit; Origami Surgical, Madison, NJ) for robot-assisted SCP with a 4-arm configuration and no assistant port. STUDY DESIGN: This is a retrospective case series of patients undergoing robot-assisted SCP at a tertiary center from 2018 to 2021. All surgical procedures were performed using four 8-mm robotic trocars and StitchKit device. Our objective was to review all cases in which this technique was used to determine whether the approach resulted in a safely completed procedure and any complications or adverse events. Secondary objectives were to describe patient and operative characteristics. RESULTS: In total, 422 patients underwent robot-assisted SCP for pelvic organ prolapse. The mean age was 60 ± 10 years, and mean body mass index was 27 ± 6 (calculated as weight in kilograms divided by height in meters squared). Most patients had stage 3 prolapse (73%) and underwent concomitant hysterectomy (70%). Ninety-nine percent (n = 416) of cases were completed robotically. StitchKit was successfully inserted and removed in all robotic cases with correct needle counts. All patients had postoperative visits, and 80% followed up at 3 months. No umbilical/port site hernias, operative site infections, or adverse events were reported. CONCLUSIONS: Robot-assisted SCP can be performed safely using a 4-arm robotic configuration and suture kit device. This setup eliminates incisions greater than 8 mm and an assistant port, allowing for surgical efficiency without compromising patient outcomes.
RESUMO
IMPORTANCE: Routine screening for urinary incontinence (UI) by primary care providers (PCPs) is recommended. OBJECTIVES: We aimed to describe the rate of incident UI diagnosed at annual PCP visits, the prevalence of UI in a large primary care population, and estimate the rate of screening for UI during primary care preventive and annual wellness visits. Secondary aims were to describe PCP knowledge and behavior as they relate to UI screening and diagnosis. STUDY DESIGN: The electronic health record was used to abstract the number of adult female patients seen by PCPs within a regional health system with a diagnosis of UI before our study period and with a new diagnosis over a 2-year period. Additional new diagnoses and screening practices were found on chart review of an additional 824 representative charts. Primary care providers within the health system were surveyed about their screening practices and knowledge about UI. RESULTS: There were 192,053 women primary care patients seen over 2 years. A total of 5.7% had a UI diagnosis preceding the study period and 3.4% had a UI diagnosis during the study period. A total of 42% of PCPs reported that they screen for UI at least half the time and none were completely satisfied with their ability to screen for UI. Sixteen percent of annual wellness visits had any documentation of screening for UI. CONCLUSION: In a large primary care population, screening for and detection of UI in women was low.

BACKGROUND: Nutritional status is paramount in Cystic Fibrosis (CF) and is directly correlated with morbidity and mortality. The first ESPEN-ESPGHAN-ECFS guidelines on nutrition care for infants, children, and adults with CF were published in 2016. An update to these guidelines is presented. METHODS: The study was developed by an international multidisciplinary working group in accordance with officially accepted standards. Literature since 2016 was reviewed, PICO questions were discussed and the GRADE system was utilized. Statements were discussed and submitted for on-line voting by the Working Group and by all ESPEN members. RESULTS: The Working Group updated the nutritional guidelines including assessment and management at all ages. Supplementation of vitamins and pancreatic enzymes remains largely the same. There are expanded chapters on pregnancy, CF-related liver disease, and CF-related diabetes, bone disease, nutritional and mineral supplements, and probiotics. There are new chapters on nutrition with highly effective modulator therapies and nutrition after organ transplantation.
