Participatory approaches to programme design, planning and early implementation: experiences from a safe surgery project in Nigeria.

MOMENTUM Safe Surgery in Family Planning and Obstetrics is a global project that strengthens surgical ecosystems through partnership with country institutions. In Nigeria, the project implements in Bauchi, Ebonyi, Kebbi and Sokoto states and the Federal Capital Territory, focusing on surgical obstetrics, holistic fistula care and female genital mutilation/cutting prevention and care. The project utilized participatory approaches during its design, planning and early implementation phases. During the design phase, the project employed a co-creation process featuring a desk review, key informant interviews and stakeholder workshops at community, facility, and government levels to actively listen to, identify and incorporate local perspectives on surgical ecosystem gaps and priorities. Initial findings, shared at state- and national-level workshops, helped collectively identify and prioritize context-specific interventions. The resulting co-created workplan features interventions to strengthen surgical services based on the National Surgical, Obstetrics, Anaesthesia and Nursing Plan (NSOANP). Upon workplan approval, the planning phase involved meeting with each State Ministry of Health (MOH) to prioritize workplan interventions for implementation and to define the finer details needed to drive early implementation processes. Preliminary achievements during early implementation include state commitments to include a costed facility NSOANP in 2023 annual operational plans, mitigation of health facility staffing shortages and review of national fistula and surgical Health Management Information System indicator data flow and advocacy to the Federal MOH resulting in improved fistula data quality and availability. Well-established state and national systems, structures, policies and guidelines enable this programming approach. Since communication between institutional actors is often limited, these approaches necessitate building and maintaining relationships and knowledge-sharing, which requires a significant up-front time investment that must be balanced with donor/partner desires for rapid deliverables. Linking different actors within the health system together through co-creation/co-implementation represents a crucial step in building sustainable country ownership and oversight for surgical ecosystems strengthening interventions.

Transcutaneous electrical nerve stimulation (TENS) versus sham TENS in adult ED patients with abdominal pain: A clinical trial.

OBJECTIVE: There is a growing consensus that the risks of current pharmacologic analgesics warrant consideration of alternative modalities for acute and chronic pain control. The objective of this study was to evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) in adult emergency department (ED) patients presenting with abdominal pain. METHODS: We conducted a patient and observer blinded randomized controlled trial comparing TENS to sham TENS. The study was conducted at a large suburban academic ED. Patients with abdominal pain and a verbal numeric pain scale (VNS) of 5 or greater were randomized to TENS or sham TENS applied via 4 skin pads, one in each abdominal quadrant for 30 min. The primary outcome was change in pain scores 30 min after the intervention. Our study had 80% power to detect a between group difference of 1.5 points on the VNS. RESULTS: 81 patients were randomized to TENS (n = 41) or sham TENS (n = 40). Groups were similar in baseline characteristics. The mean (SD) reductions in pain scores were 1.9 (2.1) and 1.7 (2.6) in patients treated with TENS and sham TENS respectively (P = 0.81). Use of rescue medications in patients with treated with TENS and sham TENS was similar (49 vs 55% respectively, P = 0.66). CONCLUSIONS: Application of TENS to the abdominal wall did not result in more effective pain relief than sham TENS in adult ED patients with abdominal pain.

Parental self-control facilitates adolescent psychological adjustment sequentially through parents' perceived stress/mindful parenting and adolescent self-control.

Adolescence is a unique developmental period marked with significant changes and challenges. As such, maintaining optimal psychological adjustment is crucial for young people, especially during the COVID-19 pandemic when their adjustment became more challenging. Self-control is a vital ability assisting individuals to navigate difficulties and stay well-adjusted during turbulent times. While the associations between adolescent self-control and adjustment have been well-documented, parental self-control has been considered to play a more fundamental role in adolescent adjustment. However, this consideration has received scant research. Drawing on the intergenerational transmission model of self-regulation, we examined an understudied yet plausible idea that parental self-control facilitates adolescent adjustment through parents' lower levels of perceived stress/better mindful parenting and adolescents' improved self-control. A two-wave survey study, spanning 1 year apart, was conducted among 426 Chinese adolescents (Mage = 11.6 years, 53.5% boys) and their parents. Parents rated their self-control, perceived stress, and mindful parenting at T1, while adolescents rated their self-control and adjustment (i.e., psychological difficulties and life satisfaction) at T1 and T2. The results of chain mediation model showed that after controlling for demographic covariates and baseline levels of adolescent self-control and adjustment, T1 paternal self-control facilitated T2 adolescent adjustment through fathers' lower levels of perceived stress and adolescents' improved self-control. By contrast, T1 maternal self-control facilitated T2 adolescent adjustment through mothers' better mindful parenting and adolescents' improved self-control. These findings advance our understanding of how self-control is transmitted from parents to offspring and clarify the processes of how parental self-control facilitates adolescent adjustment.

Admission and Care Practices in United States Well Newborn Nurseries.

OBJECTIVES: Late preterm and term infants comprise 97.3% of annual births in the United States. Admission criteria and the availability of medical interventions in well newborn nurseries are key determinants of these infants remaining within a mother-infant dyad or requiring a NICU admission and resultant separation of the dyad. The objective of this study was to identify national patterns for well newborn nursery care practices. METHODS: We surveyed a physician representative from each nursery in the Better Outcomes through Research for Newborns Network. We described the admission criteria and clinical management of common newborn morbidities and analyzed associations with nursery demographics. RESULTS: Of 96 eligible nursery representatives, 69 (72%) completed surveys. Among respondents, 59 (86%) used a minimal birth weight criterion for admission to their well newborn nursery. The most commonly used criteria were 2000 g (n = 29, 49%) and 1800 g (n = 19, 32%), with a range between 1750 and 2500 g. All nurseries used a minimal gestational age criterion for admission; the most commonly used criterion was 35 weeks (n = 55, 80%). Eleven percent of sites required transfer to the NICU for phototherapy. Common interventions in the mother's room included dextrose gel (n = 56, 81%), intravenous antibiotics (n = 35, 51%), opiates for neonatal abstinence syndrome (n = 15, 22%), and an incubator for thermoregulation (n = 14, 20%). CONCLUSIONS: Wide variation in admission criteria and medical interventions exists in well newborn nurseries. Further studies may help identify evidence-based optimal admission criteria to maximize care within the mother-infant dyad.

Design and Implementation of a Program Development Practicum for Faculty Education and Advancement of Clinical Programs.

Physicians are often tasked to develop and lead collaborative, program development efforts but many have limited formal training. We designed and evaluated a professional development workshop series to provide our faculty members with a framework and tools for the development of clinical programs: the Program Development Practicum (PDP). Faculty identified a clinical program of focus and for each clinical program identified, a program proposal, SBAR communication (situation, background, assessment, recommendation), executive summary, 1-min elevator pitch, and budget was developed. Five clinical programs were identified for improvement including: Inflammatory Bowel Disease, Celiac Disease, Transition of Care, Integrative Health Clinic, and Endoscopic Procedures. At the conclusion of the PDP, these programs were presented to key hospital leaders and resulted in an investment of resource support. Faculty also reported increased understanding of overall program development with the largest gains in knowledge in proposal writing and marketing. Overall, the PDP allowed for a revamp of key clinical services and faculty clarity on resource availability and expectations. We plan to continue with annual engagement of hospital leaders to share updates.

Biochemical characterization of Soxhlet-extracted pulp oil of Canarium schweinfurthii Engl. fruit in Nigeria.

Characterization and further development of underutilized/underexploited indigenous tropical seed oils are essential to supplement both nutritional and industrial needs of an ever-increasing African (and global) population. Before now and to our best knowledge, the previous research involved Canarium schweinfurthii Engl. fruit specific to Nigeria appear to have been more on the evaluation of seed, pulp, and essential oils (from the seed), but much less on the pulp oil. To supplement existing information, this current work has aimed to biochemically characterize the Soxhlet-extracted pulp oil of C. schweinfurthii fruit gathered from a community situated in the South-east of Nigeria. Specifically, the biochemical characterization comprised the determinations of proximate compositions, lipid peroxidation, fatty acid profile, as well as carotenoids, sterols, and tocopherols. Processing the fruit sample to pulp oil involved, among others, oven-drying, and grinding, prior to the Soxhlet extraction. Results of proximate components of C. schweinfurthii pulp oil showed the following trend: crude fat content (~ 49.32%) > carbohydrates (~ 37.93%) > moisture content (~ 8.62%) > ash content (~ 3.74%) > crude protein content (~ 0.39%) values. The lipid peroxidation attributes comprised acid (~ 23.60 mg KOH/g), peroxide (~ 33.91 mEq. O2/kg), iodine (~ 58.3 g/100 g), and saponification (~ 138.21 mg KOH/g) values. In addition to the free (~ 13.8%), saturated (~ 9.74%), and unsaturated (~ 90.26%) fatty acids, a total of fifteen (15) fatty acid methyl esters (FAMEs) spectral peaks were found, from caprylic acid (C8:0) to lignoceric acid (C24:0). Total tocopherol concentration amounted to ~ 73 mg/100 g, which comprised α, ß, γ-tocopherol, and δ-tocotrienol, with fair concentrations of carotenoids and sterols. Overall, the C. schweinfurthii pulp oil-biochemically competitive with a high concentration of unsaturated fatty acid, tocopherol, and sterol, suggests strong industrial promise.

Something Old, Something New: Ion Channel Blockers as Potential Anti-Tuberculosis Agents.

Tuberculosis (TB) remains a challenging global health concern and claims more than a million lives every year. We lack an effective vaccine and understanding of what constitutes protective immunity against TB to inform rational vaccine design. Moreover, treatment of TB requires prolonged use of multi-drug regimens and is complicated by problems of compliance and drug resistance. While most Mycobacterium tuberculosis (Mtb) bacilli are quickly killed by the drugs, the prolonged course of treatment is required to clear persistent drug-tolerant subpopulations. Mtb's differential sensitivity to drugs is, at least in part, determined by the interaction between the bacilli and different host macrophage populations. Therefore, to design better treatment regimens for TB, we need to understand and modulate the heterogeneity and divergent responses that Mtb bacilli exhibit within macrophages. However, developing drugs de-novo is a long and expensive process. An alternative approach to expedite the development of new TB treatments is to repurpose existing drugs that were developed for other therapeutic purposes if they also possess anti-tuberculosis activity. There is growing interest in the use of immune modulators to supplement current anti-TB drugs by enhancing the host's antimycobacterial responses. Ion channel blocking agents are among the most promising of the host-directed therapeutics. Some ion channel blockers also interfere with the activity of mycobacterial efflux pumps. In this review, we discuss some of the ion channel blockers that have shown promise as potential anti-TB agents.

Cryptococcal meningoencephalitis: time for action.

Cryptococcal meningoencephalitis was first described over a century ago. This fungal infection is preventable and treatable yet continues to be associated with excessive morbidity and mortality. The largest burden of disease resides in people living with HIV in low-income and middle-income countries. In this group, mortality with the best antifungal induction regimen (7 days of amphotericin B deoxycholate [1·0 mg/kg per day] and flucytosine [100·0 mg/kg per day]) in a clinical trial setting was 24% at 10 weeks. The world is now at an inflection point in terms of recognition, research, and action to address the burden of morbidity and mortality from cryptococcal meningoencephalitis. However, the scope of interventional programmes needs to increase, with particular attention to implementation science that is specific to individual countries. This Review summarises causes of excessive mortality, interventions with proven survival benefit, and gaps in knowledge and practice that contribute to the ongoing high death toll from cryptococcal meningoencephalitis.

Does Protein Supplementation Support Adaptations to Arduous Concurrent Exercise Training? A Systematic Review and Meta-Analysis with Military Based Applications.

We evaluated the impact of protein supplementation on adaptations to arduous concurrent training in healthy adults with potential applications to individuals undergoing military training. Peer-reviewed papers published in English meeting the population, intervention, comparison and outcome criteria were included. Database searches were completed in PubMed, Web of science and SPORTDiscus. Study quality was evaluated using the COnsensus based standards for the selection of health status measurement instruments checklist. Of 11 studies included, nine focused on performance, six on body composition and four on muscle recovery. Cohen's d effect sizes showed that protein supplementation improved performance outcomes in response to concurrent training (ES = 0.89, 95% CI = 0.08-1.70). When analysed separately, improvements in muscle strength (SMD = +4.92 kg, 95% CI = -2.70-12.54 kg) were found, but not in aerobic endurance. Gains in fat-free mass (SMD = +0.75 kg, 95% CI = 0.44-1.06 kg) and reductions in fat-mass (SMD = -0.99, 95% CI = -1.43-0.23 kg) were greater with protein supplementation. Most studies did not report protein turnover, nitrogen balance and/or total daily protein intake. Therefore, further research is warranted. However, our findings infer that protein supplementation may support lean-mass accretion and strength gains during arduous concurrent training in physical active populations, including military recruits.

Breast Implant-associated Anaplastic Large Cell Lymphoma: An Evidence-based Systematic Review.

OBJECTIVE: This evidence-based systematic review synthesizes and critically appraises current clinical recommendations and advances in the diagnosis and treatment of BIA-ALCL. This review also aims to broaden physician awareness across diverse specialties, particularly among general practitioners, breast surgeons, surgical oncologists, and other clinicians who may encounter patients with breast implants in their practice. BACKGROUND: BIA-ALCL is an emerging and treatable immune cell cancer definitively linked to textured-surface breast implants. Although the National Comprehensive Cancer Network (NCCN) consensus guidelines and other clinical recommendations have been established, the evidence supporting these guidelines has not been systematically studied. The purpose of this evidence-based systematic review is to synthesize and critically appraise current clinical guidelines and recommendations while highlighting advances in diagnosis and treatment and raising awareness for this emerging disease. METHODS: This evidence-based systematic review evaluated primary research studies focusing on the diagnosis and treatment of BIA-ALCL that were published in PubMed, Google Scholar, and other scientific databases through March 2020. RESULTS AND CONCLUSIONS: The clinical knowledge of BIA-ALCL has evolved rapidly over the last several years with major advances in diagnosis and treatment, including en bloc resection as the standard of care. Despite a limited number of high-quality clinical studies comprised mainly of Level III and Level V evidence, current evidence aligns with established NCCN consensus guidelines. When diagnosed and treated in accordance with NCCN guidelines, BIA-ALCL carries an excellent prognosis.

NPC-0501 trial on the value of changing chemoradiotherapy sequence, replacing 5-fluorouracil with capecitabine, and altering fractionation for patients with advanced nasopharyngeal carcinoma.

BACKGROUND: A current recommendation for the treatment of patients with locoregionally advanced nasopharyngeal carcinoma (NPC) is conventional fractionated radiotherapy (RT) with concurrent cisplatin followed by adjuvant cisplatin and 5-fluorouracil (PF). This randomized NPC-0501 trial evaluated the therapeutic effect of changing to an induction-concurrent sequence or accelerated-fractionation sequence, and/or replacing 5-fluorouracil with capecitabine (X). METHODS: Patients with American Joint Committee on Cancer/International Union Against Cancer stage III to stage IVB NPC initially were randomly allocated to 1 of 6 treatment arms (6-arm full-randomization cohort). The protocol was amended in 2009 to permit centers to opt out of randomization regarding fractionation (3-arm chemotherapy cohort). RESULTS: A total of 803 patients were accrued (1 of whom was nonevaluable) from 2006 to 2012. Based on the overall comparisons, neither changing the chemotherapy sequence nor accelerated fractionation improved treatment outcome. However, secondary analyses demonstrated that when adjusted for RT parameters and other significant factors, the induction-concurrent sequence, especially the induction-PX regimen, achieved significant improvements in progression-free survival (PFS) and overall survival. Efficacy varied among different RT groups: although no impact was observed in the accelerated-fractionation group and the 3-arm chemotherapy cohort, a comparison of the induction-concurrent versus concurrent-adjuvant sequence in the conventional-fractionation group demonstrated a significant benefit in PFS (78% vs 62% at 5 years; P = .015) and a marginal benefit in overall survival (84% vs 72%; P = .042) after adjusting for multiple comparisons. Comparison of the induction-PX versus the adjuvant-PF regimen demonstrated better PFS (78% vs 62%; P = .027) without an increase in overall late toxicity. CONCLUSIONS: For patients irradiated using conventional fractionation, changing the chemotherapy sequence from a concurrent-adjuvant to an induction-concurrent sequence, particularly using induction cisplatin and capecitabine, potentially could improve efficacy without an adverse impact on late toxicity. However, further validation is needed for confirmation of these findings.

Low-Interventional Approaches to Intrapartum Care: Hospital Variation in Practice and Associated Factors.

INTRODUCTION: Despite evidence supporting the safety of low-interventional approaches to intrapartum care, defined by the American College of Obstetricians and Gynecologists as "practices that facilitate a physiologic labor process and minimize intervention," little is known about how frequently such practices are utilized. We examined hospital use of low-interventional practices, as well as variation in utilization across hospitals. METHODS: Data came from 185 California hospitals completing a survey of intrapartum care, including 9 questions indicating use of low- versus high-interventional practices (eg, use of intermittent auscultation, nonpharmacologic pain relief, and admission of women in latent labor). We performed a group-based latent class analysis to identify distinct groups of hospitals exhibiting different levels of utilization on these 9 measures. Multivariable logistic regression identified institutional characteristics associated with a hospital's likelihood of using low-interventional practices. Procedure rates and patient outcomes were compared between the hospital groups using bivariate analysis. RESULTS: We identified 2 distinct groups of hospitals that tended to use low-interventional (n = 44, 23.8%) and high-interventional (n = 141, 76.2%) practices, respectively. Hospitals more likely to use low-interventional practices included those with midwife-led or physician-midwife collaborative labor management (adjusted odds ratio [aOR], 7.52; 95% CI, 2.53-22.37; P < .001) and those in rural locations (aOR, 3.73; 95% CI, 1.03-13.60; P = .04). Hospitals with a higher proportion of women covered by Medicaid or other safety-net programs were less likely to use low-interventional practices (aOR, 0.96; 95% CI, 0.93-0.99; P = .004), as were hospitals in counties with higher medical liability insurance premiums (aOR, 0.53; 95% CI, 0.33-0.85; P = .008). Hospitals in the low-intervention group had comparable rates of severe maternal and newborn morbidities but lower rates of cesarean birth and episiotomy compared with hospitals in the high-intervention group. DISCUSSION: Only one-quarter of hospitals used low-interventional practices. Attention to hospital culture of care, incorporating the midwifery model of care, and addressing medical-legal concerns may help promote utilization of low-interventional intrapartum practices.

A prospective clinical study of Primo-Lacto: A closed system for colostrum collection.

BACKGROUND: Colostrum is the first nutritional liquid that comes out of the breast during lactation. Colostrum collection can be challenging due to the small volume produced, and because breast pumps are not designed for colostrum collection. Besides pumping colostrum, the generally accepted practice is to use any available container to hand-express colostrum. Transfer between containers may lead to contamination, higher chance of infection and loss of colostrum. Our aim was to understand if a dedicated colostrum collection system (Primo-Lacto, Maternal Life, LLC, Palo Alto, CA) is more effective than standard hospital practice. METHODS: Mothers who delivered preterm infants < 34 weeks gestation and mothers with non-latching infants were approached within 24 hours of delivery. Surveys were distributed to participating patients (n = 67), and nurses or lactation consultants (n = 89). Mothers compared ease of use, their confidence level and satisfaction with the amount collected during standard practice vs. the colostrum collection system. Nurses or lactation consultants compared ease of use, differences in colostrum loss and time invested collecting. Quantitative data were analyzed using the Wilcoxon signed rank test and qualitative data were analyzed with grounded theory methods. RESULTS: For mothers, ease of use and confidence were significantly better when they used the colostrum collection system than when they used the standard collection procedure, and this difference was true for both hand and pump expression (p<0.01). Nurses and lactation consultants perceived that ease of use was better, and percent of colostrum lost was significantly less with the colostrum collection system for both hand and pump expression. The collection times were not significantly different between the colostrum collection system and standard practice. CONCLUSION: The colostrum collection system is a tool to help facilitate successful colostrum collection and improve the experience both for clinicians and patients.

Transcutaneous bilirubinometer use and practices surrounding jaundice in 150 California newborn intensive care units.

OBJECTIVES: Transcutaneous bilirubin measurements (TcBs) provide a noninvasive method for screening infants for hyperbilirubinemia and have been used extensively in term and late preterm newborns in well baby nurseries, offices, and outpatient clinics. Several studies have also demonstrated the utility of TcBs as a screening tool for infants > 28 weeks' gestation and their ability to reduce the need for blood sampling. The objectives of this study are to identify how often TcBs are used among California Newborn Intensive Care Units (NICUs) in preterm, late preterm and term infants, and other aspects of jaundice management. METHODS: We conducted a survey on TcB use and practices relating to jaundice management in 150 California NICUs between April and October 2016. RESULTS: TcB screening is routinely used in 28% (42/150) of NICUs. Only 7% (11/150) of NICUs use TcB in preterm infants < 28 weeks. Practice varied similarly across NICU levels of care. Among the subset of NICUs that responded to questions related to phototherapy and screening practices, prophylactic phototherapy was used in 38% (23/59) and 90% (55/61) screened for glucose-6-phosphate dehydrogenase deficiency based on race, ethnicity, and/or family history. CONCLUSION(S): Despite studies validating the accuracy of TcB in preterm infants > 28 weeks, only 28% of California NICUs routinely use TcB devices. TcB screening in infants < 28 weeks gestation is not widely used and no recommendation can be made in this regard until there is more experience with its application using a standardized protocol in these infants and on a large scale.

Concurrent-Adjuvant Chemoradiation Therapy for Stage III-IVB Nasopharyngeal Carcinoma-Exploration for Achieving Optimal 10-Year Therapeutic Ratio.

PURPOSE: This is an updated combined analysis of 2 randomized studies (NPC-9901 and NPC-9902 trials) to evaluate the 10-year outcome attributed to the addition of concurrent-adjuvant chemotherapy for advanced locoregional nasopharyngeal carcinoma (NPC). PATIENTS AND METHODS: Eligible patients with stage III-IVB nonkeratinizing NPC were randomly assigned to radiation therapy alone (RT: 218 patients) or chemoradiation therapy (CRT: 223 patients) using 3 cycles of cisplatin (100 mg/m2) concurrent with RT, followed by 3 cycles of cisplatin (80 mg/m2) and fluorouracil (1000 mg/m2/day for 4 days). All of the patients were irradiated with conventional fractionation to ≥66 Gy. The median follow-up was 13.9 years. RESULTS: Intention-to-treat analysis confirmed that the CRT group achieved significant improvement in 10-year failure-free rate (FFR: 62% vs 52%, P = .016), progression-free survival rate (PFS: 56% vs 44%, P = .008), and overall survival rate (OS: 60% vs 50%, P = .044). There was no significant increase in overall late toxicity rate (51% vs 48%, P = .34) or noncancer deaths (19% vs 16%, P = .52). Exploratory studies showed no difference in disease control between 2 or 3 cycles of concurrent cisplatin; however, patients given 3 concurrent cycles had a significant increase in hearing impairment (40% vs 24%, P = .017). Only those who continued to receive 2 or more cycles of adjuvant cisplatin-fluorouracil achieved significant improvement in distant control (73% vs 65%, P = .037) and maximal survival gain. CONCLUSION: The addition of concurrent cisplatin plus adjuvant cisplatin-fluorouracil could significantly improve overall survival and disease control without incurring a significant increase in late toxicity or noncancer deaths. Exploratory analyses suggested that both the concurrent and the adjuvant phases contributed to tumor control. Furthermore, the number of concurrent cycles could be reduced from 3 to 2 cycles in order to achieve a similar survival benefit without incurring an excessive increase in hearing impairment. This is a useful hypothesis that warrants further validation.

The Role of Vitamin D Receptor Polymorphisms in Predicting the Response to Therapy for Nonmuscle Invasive Bladder Carcinoma.

PURPOSE: Clinical and pathological predictors of bladder carcinoma recurrence and progression are relatively well defined. However, there is a paucity of genetic data specifically on the association of single nucleotide polymorphisms in specific genes for predicting recurrence and progression following immunotherapy. The VDR gene was found to regulate the immunomodulatory effects of vitamin D and it enhances the innate immunity system. We evaluated 3 VDR single nucleotide polymorphisms and their predictive role on the response to immunotherapy. MATERIALS AND METHODS: Patients with bladder cancer at intermediate-high risk who underwent post-transurethral resection intravesical bacillus Calmette-Guérin in Singapore and Hong Kong from 1995 to 2014 were recruited for analysis. We evaluated 3 VDR single nucleotide polymorphisms using polymerase chain reaction. Kaplan-Meier survival curves and relationships with outcomes were analyzed by multivariable Cox regression. RESULTS: A total of 338 predominantly Chinese patients were included in study. Individuals carrying the VDR genotype Bsm A/G were significantly associated with lower time to recurrence after bacillus Calmette-Guérin therapy (p <0.001). On multivariable analysis the HR of recurrence in patients with the Bsm A allele was 3.95 times that in patients without the allele (p = 0.037). Patients with the VDR GATC subhaplotype were 3.05 times more likely than patients with other subhaplotypes to experience recurrences (p = 0.003). Study limitations include the small sample size and the lack of information on previous bacillus Calmette-Guérin vaccine exposure and on vitamin D levels. CONCLUSIONS: Our findings in this study suggest that various VDR single nucleotide polymorphisms are associated with recurrences after bacillus Calmette-Guérin immunotherapy. Further functional studies should be performed to elucidate the significance of the VDR gene in the management of bladder cancer and the potential therapy implications.
