Protecting Caribbean patients diagnosed with cancer from compounding disasters.

Caribbean small island developing states are becoming increasingly vulnerable to compounding disasters, prominently featuring climate-related hazards and pandemic diseases, which exacerbate existing barriers to cancer control in the region. We describe the complexities of cancer prevention and control efforts throughout the Caribbean small island developing states, including the unique challenges of people diagnosed with cancer in the region. We highlight potential solutions and strategies that concurrently address disaster adaptation and cancer control. Because Caribbean small island developing states are affected first and worst by the hazards of compounding disasters, the innovative solutions developed in the region are relevant for climate mitigation, disaster adaptation, and cancer control efforts globally. In the age of complex and cascading disaster scenarios, developing strategies to mitigate their effect on the cancer control continuum, and protecting the health and safety of people diagnosed with cancer from extreme events become increasingly urgent. The equitable development of such strategies relies on collaborative efforts among professionals whose diverse expertise from complementary fields infuses the local community perspective while focusing on implementing solutions.

Impact of the availability of midurethral slings on treatment strategies for stress urinary incontinence: a cost-effectiveness analysis.

OBJECTIVE: To perform a cost-effectiveness analysis for the surgical and non-surgical management of stress urinary incontinence (SUI) with and without the availability of midurethral sling. DESIGN: Cost-effectiveness analysis. SETTING: USA, 2019. POPULATION: Women with stress urinary incontinence. METHODS: We modelled SUI treatment pathways with and without the availability of midurethral slings, including no treatment, incontinence pessary, pelvic floor muscle physical therapy, urethral bulking injection, open and laparoscopic Burch colposuspension, and pubovaginal autologous sling. Time horizon was 2 years after initial treatment. MAIN OUTCOME MEASURES: Costs (2019 US$) included index surgery, surgical retreatment, and complications including urinary retention, de novo urgency and mesh exposure. The incremental cost-effectiveness ratio (ICER) was calculated for non-dominated treatment strategies. RESULTS: The least costly treatment strategies were incontinence pessary, pelvic floor physical therapy, no treatment and midurethral sling, respectively. Midurethral slings had the highest effectiveness. The strategy with the lowest effectiveness was no treatment. The three cost-effective strategies included pessary, pelvic floor muscle physical therapy and midurethral slings. No other surgical options were cost-effective. If midurethral slings were not available, all other surgical options were still dominated by pelvic floor muscle physical therapy. Multiple one-way sensitivity analyses confirmed model robustness. The only reasonable threshold in which outcomes would change, was if urethral bulking costs decreased 12.6%. CONCLUSIONS: The midurethral sling is the most effective SUI treatment and the only cost-effective surgical option. TWEETABLE ABSTRACT: Midurethral sling is the only cost-effective surgical treatment option for stress urinary incontinence.

Risk factors for preeclampsia and eclampsia at a main referral maternity hospital in Freetown, Sierra Leone: a case-control study.

BACKGROUND: In the African region, 5.6% of pregnancies are estimated to be complicated by preeclampsia and 2.9% by eclampsia, with almost one in ten maternal deaths being associated with hypertensive disorders. In Sierra Leone, representing one of the countries with the highest maternal mortality rates in the world, 16% of maternal deaths were caused by pregnancy-induced hypertension in 2016. In the light of the high burden of preeclampsia and eclampsia (PrE/E) in Sierra Leone, we aimed at assessing population-based risk factors for PrE/E to offer improved management for women at risk. METHODS: A facility-based, unmatched observational case-control study was conducted in Princess Christian Maternity Hospital (PCMH). PCMH is situated in Freetown and is the only health care facility providing 'Comprehensive Emergency Obstetric and Neonatal Care services' throughout the entire country. Cases were defined as pregnant or postpartum women diagnosed with PrE/E, and controls as normotensive postpartum women. Data collection was performed with a questionnaire assessing a wide spectrum of factors influencing pregnant women's health. Statistical analysis was performed by estimating a binary logistic regression model. RESULTS: We analyzed data of 672 women, 214 cases and 458 controls. The analysis yielded several independent predictors for PrE/E, including family predisposition for PrE/E (AOR = 2.72, 95% CI: 1.46-5.07), preexisting hypertension (AOR = 3.64, 95% CI: 1.32-10.06), a high mid-upper arm circumflex (AOR = 3.09, 95% CI: 1.83-5.22), presence of urinary tract infection during pregnancy (AOR = 2.02, 95% CI: 1.28-3.19), presence of prolonged diarrhoea during pregnancy (AOR = 2.81, 95% CI: 1.63-4.86), low maternal assets (AOR = 2.56, 95% CI: 1.63-4.02), inadequate fruit intake (AOR = 2.58, 95% CI: 1.64-4.06), well or borehole water as the main source of drinking water (AOR = 2.05, 95% CI: 1.31-3.23) and living close to a waste deposit (AOR = 1.94, 95% CI: 1.15-3.25). CONCLUSION: Our findings suggest that systematic assessment of identified PrE/E risk factors, including a family predisposition for PrE/E, preexisting hypertension, or obesity, should be performed early on in ANC, followed by continued close monitoring of first signs and symptoms of PrE/E. Additionally, counseling on nutrition, exercise, and water safety is needed throughout pregnancy as well as education on improved hygiene behavior. Further research on sources of environmental pollution in Freetown is urgently required.

A cost-effectiveness analysis of sentinel lymph node detection in vulvar cancer by preoperative lymphoscintigraphy versus intraoperative detection alone.

OBJECTIVE: To determine cost-effectiveness of preoperative lymphoscintigraphy (LSG) for detection of inguinofemoral sentinel lymph nodes (SLN). METHOD: We compared the use of preoperative LSG prior to SLN excision versus omission of preoperative LSG. The two outcomes were death or survival. Costs associated with the procedure were determined by CPT code and published estimates. Cost analysis was performed using Treeage software, and incremental cost-effectiveness ratios (ICERs) were calculated. The measure of effectiveness was incremental survival benefit. ICER thresholds for considering LSG to be cost-effective were based on the value of a statistical life (VSL). RESULTS: Using a baseline probability of 0.93 for finding SLN with LSG, our model estimated LSG costs were $2783.84 with 84.7% survival. Our model then estimated the cost and survival without LSG by varying the SLN detection rate. Survival was equivalent when probability of SLN detection without LSG was 0.93. If detection without LSG was >0.93, not performing LSG was the dominant strategy. Costs were equal when probability of finding SLN without LSG was 0.6. For any SLN detection without LSG below 0.6, performing LSG was the dominant strategy. Formal cost-effectiveness analysis was performed using ICERs for probabilities from 0.60 to 0.93. In this range, costs were higher with LSG, but survival was improved. As long as the incremental detection with LSG was at least 1.05% to 1.47% higher, LSG was cost-effective with ICERs below the VSL. CONCLUSION: In our model, LSG is cost-effective as long as it increases detection of SLN by at least 1.05-1.47%.

Reprint of: Impact of elective on students' perceptions of treating patients with a substance use disorder.

OBJECTIVE: To evaluate the impact of a substance use disorder (SUD) elective curriculum on students' perceptions of treating patients with SUDs using the Drug and Drug Problems Perceptions Questionnaire (DDPPQ). METHODS: In 2017, a third-year pharmacy elective, conceptualizing SUD as a chronic, relapsing brain disease with psychosocial and societal influencers, was introduced. A linked pre- and postcourse assessment using the DDPPQ was carried out for the following categories: role adequacy, role support, job satisfaction, role-related self-esteem, and role legitimacy. RESULTS: A total of 63 students were enrolled in the elective and 54 paired questionnaires were available for analysis. There was a statistically significant improvement in attitude across all 5 categories of the DDPPQ. CONCLUSION: Students' attitudes toward working with patients with SUD improved after completing the elective. This study indicates that teaching student pharmacists about effectively recognizing and treating SUDs may result in more willingness to work with these patients in the future.

Thyroid eye disease presenting with superior rectus/levator complex enlargement.

Purpose: To describe the demographic and clinical characteristics of patients with thyroid eye disease (TED) who present with predominate superior rectus/levator complex involvement.Methods: A multi-institutional retrospective review was performed to identify patients with TED who presented with superior isolated or predominate rectus/levator involvement. Baseline and subsequent visits were reviewed to characterize the clinical course.Results: Nineteen patients were identified. All patients had imaging demonstrating an enlarged levator/superior rectus complex. At presentation, the mean clinical activity score (CAS) was 2.1 (range: 0-5). Nineteen (100%) patients had proptosis on the affected side. Lid abnormalities, including upper/lower eyelid retraction and ptosis were higher on affected side compared to the unaffected side. Eleven (58%) patients had vertical misalignment. Mean thyroid stimulating immunoglobulin (TSI) was 3.7 (range: 1-7.1). Mean follow-up time was 18 months (range: 0-60 months). At last follow-up, the mean CAS was 1.3 (range 0-5). Ten (53%) patients had proptosis. Eleven (58%) patients had vertical misalignment. Repeat imaging in eight patients showed interval enlargement of other extraocular muscles.Conclusions: The presentation of TED with superior rectus/levator complex enlargement may be under-appreciated. Orbital imaging, as well as laboratory evaluation, may help support a diagnosis of TED. In the setting of abnormal TSI and/or thyrotropin receptor antibody, presence of upper eyelid retraction, and an otherwise unremarkable laboratory and systemic evaluation, a presumptive diagnosis of TED may be made, and the patient can be followed closely, as he/she is likely to develop involvement of other extraocular muscles, consistent with a more typical presentation of TED.

MRI measurement of residual cervical length after radical trachelectomy for cervical cancer and the risk of adverse pregnancy outcomes: a blinded imaging analysis.

OBJECTIVE: To determine the association between the residual cervix measured on postoperative MRI after radical vaginal trachelectomy (RVT) and adverse obstetrical outcomes. DESIGN: Observational study. SETTING: Referral Cancer centre. POPULATION: Women who conceived after RVT for cervical cancer at the Royal Marsden Hospital, London, between 1995 and 2015. METHODS: Postoperative MRI scans were analysed by three researchers. The agreement between researchers was assessed by Pearson's correlation coefficient and Bland-Altman plot. Patients were divided into two groups (<10 and ≥10 mm residual cervix) for the analysis of adverse obstetrical outcomes. MAIN OUTCOME MEASURES: Late miscarriage, premature delivery, premature rupture of membranes (PROM) and chorioamnionitis. RESULTS: Thirty-one MRI scans were available; 29 of these women had a pregnancy that progressed beyond the first trimester. There was a strong reproducibility of the measurement of residual cervix (P < 0.001). Nineteen women (65.5%) had <10 mm residual cervix and 10 (34.5%) had ≥10 mm. Among women with <10 mm residual cervix, seven (36.8%) experienced PROM and ten (66.7%) had a preterm birth; No women with ≥10 mm residual cervix had PROM and two (22.2%) had a preterm birth (P = 0.028 and P = 0.035, respectively). Overall, there were nine (16.7%) first-trimester miscarriages, six (11.1%) late fetal losses, 12 (31.6%) preterm births and 36 (66.7%) live births. After a mean follow up of 78.1 months, 36 women were disease-free and one woman had died. CONCLUSIONS: MRI measurements of the residual cervix are reproducible between observers. The incidence of PROM and premature delivery is higher when the residual cervix after RVT is <10 mm. TWEETABLE ABSTRACT: The risk of prematurity after RVT can be predicted from measurements of residual cervical length on postoperative MRI scan.

Links between deprivation and risk of violence-related injury: a qualitative study to identify potential causal mechanisms.

Background: Deprivation has been shown to have a greater effect on risk of violent injury among adolescent girls than boys, but the mechanisms underlying this association have not been identified. Methods: In this qualitative study designed to identify causal mechanisms, focus groups involving girls aged 14-16 years attending secondary schools in South Wales, UK, were convened. Schools were recruited based on a measure of area-level deprivation. Discussions were audio-recorded and transcripts analysed thematically. Results: Girls from more deprived areas tended not to participate in organized activities, obtained alcohol from multiple sources, consumed alcoholic drinks of varying strengths in both supervised and unsupervised settings, and tended not to feel trusted by their parents; this led to poor adolescent-parent communication. Girls from less deprived areas tended to participate in organized activities, obtain alcohol from parents, consume low strength alcohol in supervised settings, and have a trusting and communicative relationship with their parents. Conclusion: Deprivation may increase risk of adolescent girls sustaining violence-related injury by increasing their time spent in unsupervised environments, with alcohol and without parental knowledge.

Trends in osteoporosis and low bone mass in older US adults, 2005-2006 through 2013-2014.

This study examined trends in osteoporosis and low bone mass in older US adults between 2005 and 2014 using bone mineral density (BMD) data from the National Health and Nutrition Examination Survey (NHANES). Osteoporosis and low bone mass appear to have increased at the femur neck but not at the lumbar spine during this period. INTRODUCTION: Recent preliminary data from Medicare suggest that the decline in hip fracture incidence among older US adults may have plateaued in 2013-2014, but comparable data on BMD trends for this time period are currently lacking. This study examined trends in the prevalence of osteoporosis and low bone mass since 2005 using BMD data from NHANES. The present study also updated prevalence estimates to 2013-2014 and included estimates for non-Hispanic Asians. METHODS: Femur neck and lumbar spine BMD by DXA were available for 7954 adults aged 50 years and older from four NHANES survey cycles between 2005-2006 and 2013-2014. RESULTS: Significant trends (quadratic or linear) were observed for the femur neck (mean T-score and osteoporosis in both sexes; low bone mass in women) but not for the lumbar spine. The trend in femur neck status was somewhat U-shaped, with prevalences being most consistently significantly higher (by 1.1-6.6 percentage points) in 2013-2014 than 2007-2008. Adjusting for changes in body mass index, smoking, milk intake, and physician's diagnosis of osteoporosis between surveys did not change femur neck trends. In 2013-2014, the percent of older adults with osteoporosis was 6% at the femur neck, 8% at the lumbar spine, and 11% at either site. CONCLUSIONS: There was some evidence of a decline in femur neck BMD between 2005-2006 and 2013-2014, but not in lumbar spine BMD. Changes in the risk factors that could be examined did not explain the femur neck BMD trends.

Spine fracture prevalence in a nationally representative sample of US women and men aged ≥40 years: results from the National Health and Nutrition Examination Survey (NHANES) 2013-2014.

Spine fracture prevalence is similar in men and women, increasing from <5 % in those <60 to 11 % in those 70-79 and 18 % in those ≥80 years. Prevalence was higher with age, lower bone mineral density (BMD), and in those meeting criteria for spine imaging. Most subjects with spine fractures were unaware of them. INTRODUCTION: Spine fractures have substantial medical significance but are seldom recognized. This study collected contemporary nationally representative spine fracture prevalence data. METHODS: Cross-sectional analysis of 3330 US adults aged ≥40 years participating in NHANES 2013-2014 with evaluable Vertebral Fracture Assessment (VFA). VFA was graded by semiquantitative measurement. BMD and an osteoporosis questionnaire were collected. RESULTS: Overall spine fracture prevalence was 5.4 % and similar in men and women. Prevalence increased with age from <5 % in those <60 to 11 % in those 70-79 and 18 % in those ≥80 years. Fractures were more common in non-Hispanic whites and in people with lower body mass index and BMD. Among subjects with spine fracture, 26 % met BMD criteria for osteoporosis. Prevalence was higher in subjects who met National Osteoporosis Foundation (NOF) criteria for spine imaging (14 vs 4.7 %, P < 0.001). Only 8 % of people with a spine fracture diagnosed by VFA had a self-reported fracture, and among those who self-reported a spine fracture, only 21 % were diagnosed with fracture by VFA. CONCLUSION: Spine fracture prevalence is similar in women and men and increases with age and lower BMD, although most subjects with spine fracture do not meet BMD criteria for osteoporosis. Since most (>90 %) individuals were unaware of their spine fractures, lateral spine imaging is needed to identify these women and men. Spine fracture prevalence was threefold higher in individuals meeting NOF criteria for spine imaging (∼1 in 7 undergoing VFA). Identifying spine fractures as part of comprehensive risk assessment may improve clinical decision making.
