RESUMO
OBJECTIVE: To evaluate clinical characteristics impacting surgical outcomes of patients undergoing pars plana vitrectomy (PPV) for complications of proliferative diabetic retinopathy (PDR). DESIGN: Retrospective consecutive observational case series of patients at a large county hospital in Dallas, Texas, from 2014 to 2019. SUBJECTS: Seven hundred thirty-two patients (933 eyes) undergoing PPV for PDR complications. METHODS: Collected data included demographics, surgical indication, adjuvant therapies, intraoperative course, complications, and best corrected visual acuity (BCVA). Patients with < 6 months of follow-up were excluded. Best corrected visual acuity was converted to logarithm of the minimum angle of resolution for analysis. Statistics performed included t test, analysis of variance, and multivariate analyses. MAIN OUTCOME MEASURES: Postoperative BCVA, primary anatomic success rate, and postoperative complications. RESULTS: Three hundred ninety-three patients were male (509 eyes; 54.5%) with an average age of 52 years. Postoperative BCVA at 6 months was significantly different among surgical indications: 0.79 versus 0.77 versus 1.20 (P < 0.0001) for vitreous hemorrhage (VH), vitreomacular interface abnormalities, and tractional retinal detachment (TRD), respectively. Adjuvant preoperative therapy with panretinal photocoagulation (PRP) versus no PRP (0.95 vs. 1.25; P < 0.001) and insulin versus no insulin (0.99 vs. 1.17; P < 0.01) were associated with improved vision. Iatrogenic breaks were associated with decreased postoperative vision (1.40 vs. 0.88; P < 0.001). The primary anatomic success rate for TRD was 85% (495 eyes). Combined TRD/RRD (tractional and rhegmatogenous retinal detachment) was associated with a lower success rate compared with macula-on/macula-off TRD, with odds ratios of 0.36, 0.46, and 0.53, respectively. Patients experiencing recurrent detachment postsurgery had worse preoperative visual acuity (VA) (1.93 vs. 1.63; P < 0.01) and were younger (47.6 vs. 50.0; P = 0.02). Postoperative complications occurred in 699 eyes (75%), with VH (498 eyes, 53%), cataract (465, 50%), and elevated intraocular pressure (149, 16%) being the most common. Two hundred thirty-six eyes (25%) required a second PPV operation. Endophthalmitis (1 eye; <1%) and choroidal detachment (5 eyes; <1%) were rare. CONCLUSIONS: In this retrospective series analyzing surgical outcomes among patients with complications from PDR, vitrectomy led to improved vision on average, with a meaningful proportion of patients receiving additional surgical intervention. Surgical indication, presenting VA, age, and adjuvant therapies appeared to impact outcomes.

RESUMO
BACKGROUND: In 2021, the Nepal national emergency care system's assessment (ECSA) identified 39 activities and 11 facility-specific goals to improve care. To support implementation of the ECSA facility-based goals, this pilot study used the World Health Organization's (WHO) Hospital Emergency Unit Assessment Tool (HEAT) to evaluate key functions of emergency care at tertiary hospitals in Kathmandu, Nepal. METHODS: This cross-sectional study used the standardized HEAT assessment tool. Data on facility characteristics, human resources, clinical services, and signal functions were gathered via key informant interviews conducted by trained study personnel. Seven tertiary referral centers in the Kathmandu valley were selected for pilot evaluation including governmental, academic, and private hospitals. Descriptive statistics were generated, and comparative analyses were conducted. RESULTS: All facilities had continuous emergency care services but differed in the extent of availability of each item surveyed. Academic institutions had the highest rating with greater availability of consulting services and capacity to perform specific signal functions including breathing interventions and sepsis care. Private institutions had the highest infrastructure availability and diagnostic testing capacity. Across all facilities, common barriers included lack of training of key emergency procedures, written protocols, point-of-care testing, and ancillary patient services. CONCLUSION: This pilot assessment demonstrates that the current emergency care capacity at representative tertiary referral hospitals in Kathmandu, Nepal is variable with some consistent barriers which preclude meeting the ECSA goals. The results can be used to inform emergency care development within Nepal and demonstrate that the WHO HEAT assessment is feasible and may be instructive in systematically advancing emergency care delivery at the national level if implemented more broadly.
RESUMO
This project aimed to assess the consistency of hypnotizability over repeated assessments when measured by the Stanford Hypnotic Susceptibility Scale: Form C (SHSS:C), and the Elkins Hypnotizability Scale (EHS) and to contrast score distribution and pleasantness of these scales. University students were administered either the SHSS:C or the EHS twice with a one-week delay by separate experimenters. Test-retest reliability of the EHS and the SHSS:C was r s =.82 (.71-.92) and r s =.66, 95% (.47-.86), respectively (Spearman's correlation). Hypnotizability was comparable at test and retest in the EHS group, SHSS:C scores decreased by the retest. We found that the SHSS:C produced higher scores than the EHS, and the pleasantness of the 2 scales was comparable. Overall, our results supported the reliability of the EHS, while SHSS:C scores were more inconsistent between the 2 assessments. More research is warranted.
