Purpose. To study epidemiology, clinical findings and visual prognosis of patients with Fuchs’ Heterochromic Iridocyclitis (FHI).Methods. A retrospective analysis was performed on 158 patients with FHI. Thirty-five patients were observed only once; the remaining 123 had a mean follow-up of 30.7 months (50 of them had a mean follow-up of 63.5 months) and in those we assessed complications, medical and surgical treatment, and long-term visual prognosis.Results. Average age at uveitis diagnosis was 27.2 years and 18.3% of patients were children. Blurred vision (54.5%) and floaters (40.5%) were the most frequent presenting symptoms. Small to medium-sized keratic precipitates (95.6%), iris atrophy (86.8%), and vitreous opacities (91.2%) were the most common signs; the prevalence of cataract and IOP increase was 63.5% and 20.1%, respectively, and their incidence was 0.1 and 0.06 eye/year. Significant risk factor for visual loss was IOP increase at presentation (p=0.02). At final examination 98% of the eye had a visual acuity ≥ 0.6, and topical (p<0.001) and systemic (p<0.001) corticosteroids therapy were used less frequently than before referral.Conclusions. FHI has a good visual prognosis, despite the significant incidence of cataract and glaucoma. A correct and prompt diagnosis might avoid unnecessary therapies and provide excellent visual outcomes.

Intestinal Pseudo Obstruction

Colonic volvulus (CV) is a rare but potentially life-threatening condition with unclear etiopathogenesis. To date, less than 80 pediatric cases have been described. Hirschsprung’s disease (HD) is associated with CV in 17% of cases, representing a significant risk factor. Non-HD CV is an even more complex entity. The aim of this study is to describe a series of patients with CV to accentuate some peculiar aspects of this disease. We performed a retrospective study (period: 2012–2021) collecting information of patients with CV. Data analyzed included: demographics, medical history, presenting symptoms and radiological and surgical details. Eleven patients (12.5 ± 2.8 years; 7F/4M) had CV (eight sigmoid, two transverse colon, one total colon). Five patients had associated anomalies and three had HD. A two-step approach with volvulus endoscopic/radiological detorsion followed by intestinal resection was attempted in eight cases (one endoscopic approach failed). Three patients required surgery at admission. At follow-up, two patients developed recurrent intestinal obstruction, one of whom also had anastomotic stenosis. Colonic volvulus is a challenging condition that requires prompt patient care. A missed diagnosis could lead to severe complications. The evaluation of the patient should include a careful histological examination (searching for HD and alpha-actin deficiency), immunologic and metabolic screening, neurological tests and detection of chronic intestinal pseudo-obstruction (CIPO). Lifelong follow-up is mandatory for the early recognition and treatment of progressive diseases involving the proximal gastrointestinal tract.

Thirty-seven patients with advanced gastroenteropancreatic neuroendocrine tumors (GEPNETs) were treated on a prospective phase II single-center study with 4 cycles of 7.8 GBq 177Lu-octreotate combined with capecitabine and temozolomide chemotherapy (CAPTEM). Each 8-week cycle combined radiopeptide therapy with 14 days of capecitabine (1500 mg/m2) and 5 days of temozolomide (200 mg/m2). The incidence of grade ≥3 hematologic toxicity was analysed. We found that at a median follow-up of 7-years (range 1-10), 6 (16%) patients developed persistent hematologic toxicity (PHT, defined as sustained grade ≥3 hematologic toxicity beyond 36-months follow up) and 3 (8%) developed MDS/AL with a median time-to-event of 46 and 34-months respectively. Estimated cumulative incidence of MDS/AL was 11% (95% CI: 3.45 to 24.01). Development of PHT was the only significant risk factor for secondary (RR, 16; 95% CI: 2.53 to 99.55; p<0.001). The median PFS was 48 months (95% CI: 40.80-55.20) and median OS was 86 months (95% CI: 56.90-115.13). 21 deaths were recorded, including 13 (62%) due to progressive disease and all 3 (14%) patients with MDS/AL. We conclude that 177Lu-octreotate CAPTEM therapy for GEPNETs is associated with a risk of long-term hematologic toxicity. The rising cumulative incidence of MDS/AL >10% mandates for the long-term monitoring of treated patients. However, time to onset is unpredictable and incidence does not correlate with conventional baseline risk factors. Novel methods are required for stratification of prospective patients based on genetic risk.

Abstract Purpose:This study evaluated the incidence rate and risk factors for developing myopia in elementary school students in Chiayi, Taiwan.Methods:This prospective cohort study comprised 1816 students without myopia (grades 1 to 5 in Chiayi County). The students underwent a noncycloplegic ocular alignment examinations using an autorefractometer and completed a questionnaires at baseline and at a 1-year follow-up. A univariate logistic regression was used to assess the effects of the categorical variables on new cases of myopia. A multinomial logistic regression was then conducted. A chi-squared test was used to compare new cases of myopia in terms of ocular alignment. A Cox hazard ratio model was then used to validate factors associated with changes in ocular alignment. A P value of <.05 was considered significant.Results: In 370 participants with new cases of myopia out of 1816 participants, a spherical error of −1.51 ± 0.6 diopters was noted at follow-up. The baseline ocular alignment was not a significant risk factor for developing myopia (exophoria vs orthophoria: OR 1.26, 95% CI 0.97-1.62; other vs. orthophoria: OR 1.15, 95% CI 0.73-1.82). However, new cases of myopia (HR 1.36, 95% CI 1.14-1.61), and baseline ocular alignment (exophoria vs orthophoria: HR 3.76, 95% CI 3.20-4.42; other vs orthophoria: HR 3.02, 95% CI 2.05-4.45) were associated with exophoria at follow-up.Conclusions: This study provided epidemiological data on the incidence of myopia in elementary school students in Chiayi, Taiwan. It also demonstrated that physiological exophoria does not predispose patients to developing myopia.

Obesity is a significant risk factor for both chronic kidney disease and end-stage renal disease. To better understand disease development, we sought to identify novel genes differentially expressed early in disease progression. We first confirmed that mice fed a high-fat (HF) diet exhibit early signs of renal injury including hyperfiltration. We then performed RNA-Seq using renal cortex RNA from C57BL6/J male mice fed either HF or control (Ctrl) diet. We identified 1,134 genes differentially expressed in the cortex on HF vs. Ctrl, of which 31 genes were selected for follow-up analysis. This included the 9 most upregulated, the 11 most downregulated, and 11 genes of interest (primarily sensory receptors and G proteins). Quantitative (q)RT-PCR for these 31 genes was performed on additional male renal cortex and medulla samples, and 11 genes (including all 9 upregulated genes) were selected for further study based on qRT-PCR. We then examined expression of these 11 genes in Ctrl and HF male heart and liver samples, which demonstrated that these changes are relatively specific to the renal cortex. These 11 genes were also examined in female renal cortex, where we found that the expression changes seen in males on a HF diet are not replicated in females, even when the females are started on the diet sooner to match weight gain of the males. In sum, these data demonstrate that in a HF-diet model of early disease, novel transcriptional changes occur that are both sex specific and specific to the renal cortex.

Objectives: Risk factors and outcomes of revision arthroscopic posterior capsulolabral repairare currently not well defined in contact athletes.Evaluation of risk factors for contact athletes who require revision arthroscopic posterior unidirectional capsulolabral repair is needed. Methods: A total of 186 contact athletes’ shoulders that underwent arthroscopic posterior capsulolabral repair at minimum 2 year follow-up were reviewed. Those who required revision surgery were compared with those who did not. Parameters assessed included age, gender, labral and/or capsular injury, level of sport, and return to sport. Glenoid bone width, bone version, labral width, and labral version were also compared. Results: Eleven shoulders required revision surgery (5.9%) at mean 12.0 year follow-up. The only significant risk factor was glenoid bone width (revision=26.4 mm vs. non-revision=29.1 mm, p=0.005). Cartilage version (p=0.676), labral version (p=0.539), and bone version (p=0.791) were not significantly different between groups, nor was labral width (p=0.751). Gender (p=0.326), labral injury (p=0.349), capsule injury (p=0.683), and level of sport (p=0.381) were not significant factors for requiring revision surgery. Both return to sport at the same level (revision=16.7% vs. non-revision=72.1%, p<0.001) and overall return to sport (revision=50% vs. non-revision=93.7%, p<0.001) was significantly worse in the revision group. Of those who had revision surgery, 33.3% stated their original surgery was not worthwhile, which was significantly higher than the 4.5% in the non-revision group (p=0.041). Conclusion: Contact athletes underwent revision arthroscopic posterior capsulolabral repair at an incidence of 5.9% at 12 year follow-up. The only significant risk factor for requiring revision surgery was smaller glenoid bone width. Return to play was significantly worse in those who required revision surgery. This data is essential for patient selection, optimal treatment techniques, and patient education as posterior shoulder capsulolabral repair in contact athletes that require revision has not previously been evaluated.

Physical inactivity is a significant risk factor for childhood obesity. Preventing obesity in the early years reduces the risk of developing chronic health conditions later. Early childhood education and care (ECEC) services are important settings to establish good preschooler physical activity behaviors. This natural experiment investigated the influence of ECEC outdoor physical environment upgrade on preschoolers’ physical activity (aged 2–5 years). Centers implemented upgrades without researcher input. Physical activity was measured by 7-day accelerometry for intervention (n = 159; 6 centers) and control (n = 138; 5 centers) groups. ECEC outdoor space was assessed using a modified Environment and Policy Assessment and Observation (EPAO) Instrument. Key outcomes were measured at baseline and 6–12 months follow-up. Fixed sandboxes, balls, portable slides, portable floor play equipment (e.g., tumbling mats), and natural grassed areas were positively associated with activity levels; fixed tunnels and twirling equipment were negatively associated with activity levels (all p < 0.05). Post-upgrade portable play equipment (balls, twirling equipment, slides, floor play equipment) increased intervention preschoolers’ moderate-vigorous physical activity (MVPA) levels compared to control (p < 0.05). Intervention preschoolers were more active than control at follow-up (58.09 vs. 42.13 min/day increase in total physical activity; 30.46 vs. 19.16 min/day increase in MVPA (all p < 0.001)). Since few preschoolers meet daily activity recommendations while at ECEC, the findings may help ECEC providers to optimize outdoor physical environments and encourage more active play among preschoolers.

ABSTRACTBackgroundResearch on the overlap between attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) in males has provided useful information on the etiology, correlates, course, and nosology of this co-morbid condition. However, it is unclear how these results extend to females. Our aim was to examine the predictors, clinical characteristics, and functional outcome of CD in a sample of female youth with and without ADHD.MethodWe conducted a blind, 5-year prospective longitudinal study of girls with (n=140) and without (n=122) ADHD, aged 6–18 years at baseline. At the 5-year follow-up, 123 (88%) and 112 (92%) of the ADHD and control children respectively were reassessed at a mean age of 16·7 years. Psychiatric disorders were assessed using blind structured diagnostic interviews.ResultsBaseline ADHD was a significant risk factor for lifetime CD throughout childhood and adolescence [hazard ratio (HR) 5·8, 95% confidence interval (CI) 2·9–11·5, p<0·001]. Among ADHD girls, childhood-onset (<12 years) CD was predicted by paternal antisocial personality disorder (ASPD), while adolescent-onset CD (⩾12 years) was predicted by family conflict. In addition, lifetime CD significantly predicted academic, psychiatric and sexual behavior problems in girls with ADHD at follow-up.ConclusionsADHD is a significant risk factor for CD in girls. CD is associated with increased risk for academic, psychiatric and sexual behavior problems compared to ADHD girls without CD. Given that the therapeutic approaches indicated by ADHD and CD differ, these findings highlight the importance of improved efforts aimed at early identification and treatment of CD in girls with ADHD.

Object The authors conducted a study to investigate the long-term natural history of unruptured intracranial aneurysms and the predictive risk factors determining subsequent rupture in a patient population in which surgical selection of cases was not performed. Methods One hundred forty-two patients with 181 unruptured aneurysms were followed from the 1950s until death or the occurrence of subarachnoid hemorrhage or until the years 1997 to 1998. The annual and cumulative incidence of aneurysm rupture as well as several potential risk factors predictive of rupture were studied using life-table analyses and Cox's proportional hazards regression models including time-dependent covariates. The median follow-up time was 19.7 years (range 0.8–38.9 years). During 2575 person-years of follow up, there were 33 first-time episodes of hemorrhage from previously unruptured aneurysms, for an average annual incidence of 1.3%. In 17 patients, hemorrhage led to death. The cumulative rate of bleeding was 10.5% at 10 years, 23% at 20 years, and 30.3% at 30 years after diagnosis. The diameter of the unruptured aneurysm (relative risk [RR] 1.11 per mm in diameter, 95% confidence interval [CI] 1–1.23, p = 0.05) and patient age at diagnosis inversely (RR 0.97 per year, 95% CI 0.93–1, p = 0.05) were significant independent predictors for a subsequent aneurysm rupture after adjustment for sex, hypertension, and aneurysm group. Active smoking status at the time of diagnosis was a significant risk factor for aneurysm rupture (RR 1.46, 95% CI 1.04–2.06, p = 0.033) after adjustment for size of the aneurysm, patient age, sex, presence of hypertension, and aneurysm group. Active smoking status as a time-dependent covariate was an even more significant risk factor for aneurysm rupture (adjusted RR 3.04, 95% CI 1.21–7.66, p = 0.02). Conclusions Cigarette smoking, size of the unruptured intracranial aneurysm, and age, inversely, are important factors determining risk for subsequent aneurysm rupture. The authors conclude that such unruptured aneurysms should be surgically treated regardless of their size and of a patient's smoking status, especially in young and middle-aged adults, if this is technically possible and if the patient's concurrent diseases are not contraindications. Cessation of smoking may also be a good alternative to surgery in older patients with small-sized aneurysms.

Many victims, victim advocates, and even law enforcement believe that protective orders are “just a piece of paper,” suggesting that they do not work or are not effective. This study examined protective order effectiveness by following 210 women for 6 months after obtaining a protective order. There are four main themes that were identified from the study results. First, protective orders were not violated for half of the women in the sample during the 6-month follow-up period. Second, even among those who experienced violations, there were significant reductions in abuse and violence. Third, overall, women were less fearful of future harm from the PO partner at the 6-month follow-up, and a vast majority felt the protective order was fairly or extremely effective. Fourth, stalking emerges as a significant risk factor for protective order violations, sustained fear, and lower perceived effectiveness of the protective order. Implications for practice and future research are discussed.

Purpose In the general population, increased adiposity is a significant risk factor for colorectal cancer (CRC), but whether obesity has similar effects in those with hereditary CRC is uncertain. This prospective study investigated the association between body mass index and cancer risk in patients with Lynch syndrome (LS). Patients and Methods Participants with LS were recruited to the CAPP2 study, in which they were randomly assigned to receive aspirin 600 mg per day or aspirin placebo, plus resistant starch 30 g per day or starch placebo (2 × 2 factorial design). Mean intervention period was 25.0 months, and mean follow-up was 55.7 months. Results During follow-up, 55 of 937 participants developed CRC. For obese participants, CRC risk was 2.41× (95% CI, 1.22 to 4.85) greater than for underweight and normal-weight participants (reference group), and CRC risk increased by 7% for each 1-kg/m2 increase in body mass index. The risk of all LS-related cancers in obese people was 1.77× (95% CI, 1.06 to 2.96; P = .03) greater than for the reference group. In subgroup analysis, obesity was associated with 3.72× (95% CI, 1.41 to 9.81) greater CRC risk in patients with LS with MLH1 mutation, but no excess risk was observed in those with MSH2 or MSH6 mutation (P = .5). The obesity-related excess CRC risk was confined to those randomly assigned to the aspirin placebo group (adjusted hazard ratio, 2.75; 95% CI, 1.12 to 6.79; P = .03). Conclusion Obesity is associated with substantially increased CRC risk in patients with LS, but this risk is abrogated in those taking aspirin. Such patients are likely to benefit from obesity prevention and/or regular aspirin.
