Background/UNASSIGNED:Hypertension is increasingly prevalent in Uganda and its clinical management remains suboptimal across the country. Prior research has elucidated some of the factors contributing to poor control, but little is known about providers' approaches to hypertension management and perceptions of barriers to care. This is particularly true in private health care settings - despite the fact that the private sector provides a substantial and growing portion of health care in Uganda. Objective/UNASSIGNED:Our exploratory, pragmatic qualitative study aimed to examine the factors affecting the quality of hypertension care from the perspective of providers working in an urban, private hospital in Uganda. We focused on the organizational and system-level factors influencing providers' approaches to management in the outpatient setting. Methods/UNASSIGNED:We conducted interviews with 19 health care providers working in the outpatient setting of a 110-bed, private urban hospital in Kampala, Uganda. We then coded the interviews for thematic analysis, using an inductive approach to generate the study's findings. Findings/UNASSIGNED:Several themes emerged around perceived barriers and facilitators to care. Providers cited patient beliefs and behaviors, driven in part by cultural norms, as a key challenge to hypertension control; however, most felt their own approach to hypertension treatment aligned with international guidelines. Providers struggled to collaborate with colleagues in coordinating the joint management of patients. Furthermore, they cited the high cost and limited availability of medication as barriers. Conclusions/UNASSIGNED:These findings offer important strategic direction for intervention development specific to this Ugandan context: for example, regarding culturally-adapted patient education initiatives, or programs to improve access to essential medications. Other settings facing similar challenges scaling up management of hypertension may find the results useful for informing intervention development as well.

BACKGROUND:Correct interpretation of the prepubescent female genital examination is a critical skill; however, physician skill in this area is limited. OBJECTIVE:To complement the bedside learning of this examination, we developed a learning platform for the visual diagnosis of the prepubescent female genital examination and examined the amount and rate of skill acquisition. PARTICIPANTS AND SETTING/METHODS:Medical students, residents, and fellows and attendings participated in an on-line learning platform. METHODS:This was a multicenter prospective cross-sectional study. Study participants deliberately practiced 158 prepubescent female genital examination cases hosted on a computer-based learning and assessment platform. Participants assigned the case normal or abnormal; if abnormal, they identified the location of the abnormality and the specific diagnosis. Participants received feedback after every case. RESULTS:We enrolled 107 participants (26 students, 31 residents, 24 fellows and 26 attendings). Accuracy (95 % CI) increased by 10.3 % (7.8, 12.8), Cohen's d-effect size of 1.17 (1.14, 1.19). The change in specificity was +16.8 (14.1, 19.5) and sensitivity +2.4 (-0.9, 5.6). It took a mean (SD) 46.3 (32.2) minutes to complete cases. There was no difference between learner types with respect to initial (p = 0.2) or final accuracy (p = 0.4) scores. CONCLUSIONS:This study's learning intervention led to effective and feasible skill improvement. However, while participants improved significantly with normal cases, which has relevance in reducing unnecessary referrals to child protection teams, learning gains were not as evident in abnormal cases. All levels of learners demonstrated a similar performance, emphasizing the need for this education even among experienced clinicians.

PURPOSE/OBJECTIVE:Reports suggest that up to 50% of women with hormone receptor-positive (HR+) breast cancer (BC) do not complete the recommended 5 years of adjuvant endocrine therapy (AET). We examined the impact of an outreach program at Kaiser Permanente Northern California (KPNC) on adherence and discontinuation of AET among patients who initiated AET. METHODS:We assembled a retrospective cohort of all KPNC patients diagnosed with HR+, stage I-III BC initiating AET before (n = 4287) and after (n = 3580) implementation of the outreach program. We compared adherence proportions and discontinuation rates before and after program implementation, both crude and adjusted for age, race/ethnicity, education, income, and stage. We conducted a pooled analysis of data from six Cancer Research Network (CRN) sites that had not implemented programs for improving AET adherence, using identical methods and time periods, to assess possible secular trends. RESULTS:In the pre-outreach period, estimated adherence in years 1, 2, and 3 following AET initiation was 75.2%, 71.0%, and 67.3%; following the outreach program, the estimates were 79.4%, 75.6%, and 72.2% (p-values < .0001 for pairwise comparisons). Results were comparable after adjusting for clinical and demographic factors. The estimated cumulative incidence of discontinuation was 0.22 (0.21-0.24) and 0.18 (0.17-0.19) at 3 years for pre- and post-outreach groups (p-value < .0001). We found no evidence of an increase in adherence between the study periods at the CRN sites with no AET adherence program. CONCLUSION/CONCLUSIONS:Adherence and discontinuation after AET initiation improved modestly following implementation of the outreach program.

BACKGROUND Takotsubo cardiomyopathy is characterized by a transient left ventricular dysfunction without obstructive coronary artery disease that mimics an acute myocardial infarction. The electrocardiogram findings of Takotsubo cardiomyopathy usually present with ST-segment elevation or depression, T-wave inversion, left bundle branch block or high-grade atrioventricular block. CASE REPORT This is a report of a case of a 58-year-old male diagnosed with Takotsubo cardiomyopathy that occurred in the setting of an acute asthma exacerbation and psychiatric exacerbation with novel electrocardiogram findings of right bundle branch block. Transthoracic echocardiogram showed a preserved ejection fraction with left ventricular apical ballooning and hyperkinesis of the basal segments. The nuclear stress test showed a fixed perfusion defect at the apical segment, but the patient refused further testing such as coronary angiography. The patient was managed medically, and a repeat echocardiogram done after 8 weeks from discharge showed a complete resolution of the apical ballooning. CONCLUSIONS It is important to recognize that patients with psychiatric illness and asthma exacerbation are predisposed to develop Takotsubo cardiomyopathy. It is also reasonable to suspect Takotsubo cardiomyopathy in the presence of new electrocardiogram findings aside from those typically seen in acute myocardial infarction, especially if it is associated with apical ballooning.

Many orthodontists working on patients with cleft lip and palate (CLP) have shown great enthusiasm for presurgical infant orthopedics (PSIO) to improve surgical outcomes with minimal intervention. Even though every clinician aims to use the best treatment modality for their patients, PSIO effects can be confounded by surgical type and timing of the primary repair, as is discussed in many studies. In such cases, one should be cautious when evaluating the particular outcomes for patients with CLP since it is difficult to differentiate the sole effect of an individual surgical or orthodontic intervention. As with any treatment methodology, nasoalveolar molding (NAM) has both benefits and limitations. Commonly cited concerns with NAM, and PSIO in general, include increased cost, increased burden of care, and a negative impact on maxillary growth. However, NAM cannot be deemed as having apparent long-term negative or positive effects on skeletal or soft tissue facial growth, based on previous studies. A review of the literature suggests that NAM does not alter skeletal facial growth when compared with the samples that did not receive PSIO. Nevertheless, the published studies on NAM show evidence of benefits to the patient, caregivers, the surgeon, and society. These benefits include documented reduction in severity of the cleft deformity prior to surgery and as a consequence improved surgical outcomes, reduced burden of care on the care givers, reduction in the need for revision surgery, and consequent reduced overall cost of care to the patient and society.

Background/UNASSIGNED:Conventionally, endoscopic ultrasound-guided fine-needle aspiration and biopsy (EUS-FNA)/EUS-FNB) has been used for tissue diagnosis of upper gastrointestinal (GI) subepithelial tumors (SETs). However, deep biopsy (DB) via endoscopic submucosal dissection (ESD) is emerging as an alternative technique, given the inadequate tissue sampling with EUS-FNA/EUS-FNB. Our aim was to conduct a systematic review and meta-analysis to report the overall diagnostic yield of DB via ESD for upper GI SETs. Methods/UNASSIGNED:PubMed, Cochrane Library and Web of Science databases were searched to identify studies (from commencement to Oct 2017) that reported the DB via ESD technique for diagnosis of upper GI SETs. The primary outcome of interest was the method's overall diagnostic yield and the secondary outcome was to the occurrence of complications. The meta-analysis was performed using the DerSimonian and Laird random-effects model. Results/UNASSIGNED:=0%) respectively. Data regarding major bleeding and perforation rates were not reported in 2 studies. Substantial heterogeneity was observed in our meta-analysis. Conclusion/UNASSIGNED:DB via ESD is an effective and safe procedure for diagnosing upper GI SETs. Further multicenter randomized controlled trials are needed to validate these findings.
