Purpose Docetaxel is known to cause eye disorders. In this study, current status of eye disorders caused by docetaxel administration every 3 weeks in Japanese patients was examined. Methods This case-control study targeted patients who were newly administered docetaxel at the Kyoto Okamoto Memorial Hospital between 1 July 2015 and 30 June 2018. Eye disorder occurrence was defined as an event in which the pharmacist confirmed the symptoms in a patient interview and the ophthalmologist diagnosed the disorder. Results Of the 89 subjects, 7 (7.9%) had eye disorders. The symptoms were watering eyes (7.9%), a stye and eye discharge (2.2% each), corneal and conjunctival disorder, visual acuity reduction, and blepharedema (1.1% each). Four patients who presented with watering eyes, eye discharge, or corneal and conjunctival disorder showed improvement with the use of eye drops such as artificial tears. Two patients who presented with a stye showed improvement with the use of oral cefcapene. One patient with mild symptoms showed spontaneous improvement. However, one patient had irreversible visual acuity reduction. The multivariate logistic regression analysis revealed that a cumulative docetaxel dose of ≥300 mg/m2 (odds ratio: 15.50, 95% confidence interval: 1.37–175.00, p = 0.027) and concomitant cyclophosphamide use (odds ratio: 13.20, 95% confidence interval: 1.13–153.00, p = 0.039) were significant risk factors associated with eye disorders. Conclusion In conclusion, it was determined that docetaxel-related eye disorders might be influenced by the cumulative dose of docetaxel and concomitant cyclophosphamide use. In addition, relatively mild symptoms improved with medication.

AbstractElevated concentrations of acylcarnitines have been associated with higher risk of obesity, type 2 diabetes and cardiovascular disease. The aim of the present study was to assess the association between L-carnitine and acylcarnitine profiles, and 2-year risk of incident lower-extremity functional impairment (LEFI). This case–control study is nested in the Seniors-ENRICA cohort of community-dwelling older adults, which included 43 incident cases of LEFI and 86 age- and sex- matched controls. LEFI was assessed with the Short Physical Performance Battery. Plasma L-carnitine and 28 acylcarnitine species were measured. After adjusting for potential confounders, medium-chain acylcarnitines levels were associated with 2-year incidence of LEFI [odds ratio per 1-SD increase: 1.69; 95% confidence interval: 1.08, 2.64; p = 0.02]. Similar results were observed for long-chain acylcarnitines [odds ratio per 1-SD increase: 1.70; 95% confidence interval: 1.03, 2.80; p = 0.04]. Stratified analyses showed a stronger association between medium- and long-chain acylcarnitines and incidence of LEFI among those with body mass index and energy intake below the median value. In conclusion, higher plasma concentrations of medium- and long-chain acylcarnitines were associated with higher risk of LEFI. Given the role of these molecules on mitochondrial transport of fatty acids, our results suggest that bioenergetics dysbalance contributes to LEFI.

Abstract Background Evidence for periconceptional or prenatal environmental risk factors for the development of congenital diaphragmatic hernia (CDH) is still scarce. Here, in a case-control study we investigated potential environmental risk factors in 199 CDH patients compared to 597 healthy control newborns. Methods The following data was collected: time of conception and birth, maternal BMI, parental risk factors such as smoking, alcohol or drug intake, use of hairspray, contact to animals and parental chronic diseases. CDH patients were born between 2001 and 2019, all healthy control newborns were born in 2011. Patients and control newborns were matched in the ratio of three to one. Results Presence of CDH was significantly associated with maternal periconceptional alcohol intake (odds ratio = 1.639, 95% confidence interval 1.101–2.440, p = 0.015) and maternal periconceptional use of hairspray (odds ratio = 2.072, 95% confidence interval 1.330–3.229, p = 0.001). Conclusion Our study suggests an association between CDH and periconceptional maternal alcohol intake and periconceptional maternal use of hairspray. Besides the identification of novel and confirmation of previously described parental risk factors, our study underlines the multifactorial background of isolated CDH.

Introduction: Sleep duration has been regarded as a potential risk factor for cardiovascular disease and stroke. Short sleep duration is linked with higher stroke incidence, and mortality. Moreover, and paradoxically, long sleep duration is also reported to be positively associated with stroke incidence. However, the impact of sleep duration on the intracerebral hemorrhage (ICH) risk remains unclear. Hypothesis: We assessed the relationship between sleep duration and the risk of ICH. Methods: We performed a nationwide, multicenter matched case-control study to investigate the risk factors for hemorrhagic stroke, using patients from 33 hospitals in Korea. We enrolled a total of 490 patients with ICH and 980 age- and sex-matched controls. We obtained information regarding sleep, sociodemographic factors, lifestyle, and medical history before ICH onset, using qualified structured questionnaires. Sleep duration was categorized as ≤5, 6, 7, 8, and ≥9 hours. We chose sleep duration of 7 h as the reference duration. Results: The included patients were mostly male (58.2%) with a mean age of 57 years. The number of subjects with long sleep duration, more than 8 h, was significantly greater in the ICH group than in the control group (≥8 h, 30.4% vs. 22.6%, P = 0.002). Compared to 7 h, long sleep duration participants tended to be older, be more hypertensive, and be more likely to have blue collar jobs, lower education levels, and poorer marital status (i.e., unmarried or divorced/separated). After controlling for confounding factors, we found that longer sleep duration was independently associated with the risk of ICH in a dose-response manner (8 h: Odds ratio, 1.44; confidence interval, 1.01-2.07; ≥9 h: Odds ratio, 2.60; confidence interval, 1.50–4.49). Conclusions: In conclusion, our study suggested that long sleep duration is positively related to ICH risk in a dose-dependent manner. In this context, our data might suggest that sleep duration is a modifiable risk factor for ICH.

Study Design: Retrospective case control study. Objectives: Adjacent-level ossification development (ALOD) is a distinct form of adjacent segmental degeneration that has been recognized to occur after anterior cervical discectomy and fusion (ACDF). It is unclear whether ACDF with plate versus standalone has an effect on rates of ALOD. This retrospective case-control study aims to assess the rate of ALOD in a large series of patients undergoing ACDF with and without plate and factors causing ALOD. Methods: Data was collected for patients undergoing ACDF from January 2009 to July 2016. Data collected was from multiple centers and included demographic data, surgical data, radiological imaging at time of surgery, and serial follow-up imaging. The radiology for ALOD was independently reviewed. Cohorts were divided into ACDF with plate (Group P = plate) and ACDF without plate (Groups S = standalone) and outcomes were compared. Results: There were 260 patients with 138 (53%) in Group P and 122 (47%) in Group S. ALOD was observed in 15.3% of patients overall, 29% in group P and 2.8% in group S ( P < .001). Following multivariate adjustment, statistically significant association was found between use of plate and ALOD (odds ratio = 12.8, 95% confidence interval = 3.52-45.45, P < .001). Plate-to-disc distance <5 mm was significantly associated with ALOD (odds ratio = 13.5, 95% confidence interval = 3.83-47.62, P < .001). Conclusion: The use of anterior plate with ACDF was associated with ALOD. Plate-to-disc distance <5 mm was significantly associated with ALOD even after adjustment for confounding factors. We conclude utilization of standalone cages or cages with plate with more than 5 mm distance from adjacent disc to minimize ALOD.

Abstract The high frequency of α+-thalassemia in malaria-endemic regions may reflect natural selection due to protection from potentially fatal severe malaria. In Africa, bearing 90% of global malaria morbidity and mortality, this has not yet been observed. We tested this hypothesis in an unmatched case-control study among 301 Ghanaian children with severe malaria and 2107 controls (62% parasitemic). In control children, α+-thalassemia affected neither prevalence nor density of Plasmodium falciparum. However, heterozygous α+-thalassemia was observed in 32.6% of controls but in only 26.2% of cases (odds ratio [OR], 0.74; 95% confidence interval [CI], 0.56-0.98). Protection against severe malaria was found to be pronounced comparing severe malaria patients with parasitemic controls (adjusted OR in children &lt; 5 years of age, 0.52; 95% CI, 0.34-0.78) and to wane with age. No protective effect was discernible for homozygous children. Our findings provide evidence for natural selection of α+-thalassemia in Africa due to protection from severe malaria.

Background/objectives Venous ulcers carry psychological and high financial burden for patients, causing depression, pain, and limitation of mobility. The study aimed to identify factors associated with an increased risk of venous ulceration in patients with varicose veins in Armenia. Methods A case-control study design was utilized enrolling 80 patients in each group, who underwent varicose treatment surgery in two specialized surgical centers in Armenia during 2013–2014 years. Cases were patients with varicose veins and venous leg ulcers. Controls included patients with varicose veins but without venous leg ulcers. Data were collected using interviewer-administered telephone interviews and medical record abstraction. Multiple logistic regression analysis was used to identify the risk factors of venous ulceration. Results There were more females than males in both groups (72.5% of cases and 85.0 % of controls). Cases were on average older than controls (53.9 vs. 39.2 years old, p ≤ 0.001). After adjusting for potential confounders, the estimated odds of developing venous ulcer was higher in patients with history of post thrombotic syndrome (odds ratio = 14.90; 95% confidence interval: 3.95–56.19; p = 0.001), with higher average sitting time (odds ratio = 1.32 per hour of sitting time; 95% confidence interval: 1.08–1.61; p = 0.006), those with reflux in deep veins (odds ratio = 3.58; 95% confidence interval: 1.23–10.31; p = 0.019) and history of leg injury (odds ratio = 3.12; 95% confidence interval: 1.18–8.23; p = 0.022). Regular exercise in form of walking (≥5 days per week) was found to be a protective factor from venous ulceration (odds ratio = 0.26; 95% confidence interval: 0.08–0.90; p = 0.034). Conclusion We found that reflux in deep veins, history of leg injury, history of post thrombotic syndrome, and physical inactivity were significant risk factors for venous ulceration in patients with varicose veins, while regular physical exercise mitigated that risk. Future studies should investigate the relationships between the duration and type of regular exercise and the risk of venous ulceration to make more specific recommendations on preventing ulcer development.

Objective.Groin wound infection (GWI) after femoral artery catheterization is unusual. However, several reports of GWI associated with the use of a Perclose device appear in the surgical literature.Design.A case-control study.Setting.We pooled 23 cases and 83 controls from a university hospital and a community medical center.Patients.A case was defined as a patient who developed a GWI after a femoral artery catheterization. At the university hospital, 3 controls were randomly selected from the at-risk population and matched to each case by time of procedure only (within 2 weeks). At the community medical center, 4 controls were selected and matched to each case by time of procedure (within 2 weeks), sex, and age (within 5 years).Results.We considered several covariates, including age, sex, body mass index, medical conditions, Perclose use, hematoma formation, and antithrombotic therapy. In a multivariate model, only hematoma formation (odds ratio, 68.8; 95% confidence interval, 12.1-391.4) and glycoprotein IIb/IIIa platelet inhibitor therapy (odds ratio, 6.1; 95% confidence interval, 1.1-33.6) were statistically significant predictors of GWI; Perclose use (odds ratio, 0.9; 95% confidence interval, 0.2-3.7) was not a statistically significant predictor of GWI. However, most of the hematomas (15/17) formed after procedures during which a Perclose device was used.Conclusion.Perclose use did not have any additional effect on GWI risk beyond the effect that hematoma formation had.

An increased incidence of domestic hepatitis A without any obvious source of infection in Sweden and a small outbreak in late spring 2001 led to the undertaking of a case-control study. Consumption of imported rocket salad was clearly associated with disease (odds ratio 9.1, 95% confidence interval 1.5 to 69). The importation of vegetables from countries where hepatitis A is endemic to countries where this disease is not endemic continues to be a public health problem.

The aim of the present study was to assess atypical changes in urothelial cells among petroleum station workers. This is a case control study, investigating 300 participants by cytological methods. Of the 300 participants, 150 were cases (exposed to petroleum products) and 150 were controls (non-exposed). Full voided urine was obtained and was cytologically assessed. Cytological atypia was identified in nine (6%) out of the 150 cases and could not be identified in 141/150 (94%) of the cases, whereas, in the control group, cytological atypia was recognized in four (2.7%) of the 150 controls and could not be identified in 146/150 (97.3%). The risk associated with petroleum product exposure, the odds ratio (OR), and 95% confidence interval (CI) was 2.33 (0.7015–7.7378), P = 0.1673. Exposure of petroleum station workers to petroleum products increases the risk of urothelial atypical changes, which may progress to precancerous and cancerous changes.

Objective To investigate the association between smoking and orofacial clefts in the United Kingdom. Design Case-control study in which the mother's exposure to tobacco smoke was assessed by a structured interview. Setting Scotland and the Manchester and Merseyside regions of England. Participants One hundred ninety children born with oral cleft between September 1, 1997, and January 31, 2000, and 248 population controls, matched with the cases on sex, date of birth, and region. Main Outcome Measure Cleft lip with or without cleft palate and cleft palate. Results There was a positive association between maternal smoking during the first trimester of pregnancy and both cleft lip with or without cleft palate (odds ratio 1.9, 95% confidence interval 1.1 to 3.1) and cleft palate (odds ratio 2.3, 95% confidence interval 1.3 to 4.1). There was evidence of a dose-response relationship for both types of cleft. An effect of passive smoking could not be excluded in mothers who did not smoke themselves. Conclusion The small increased risk for cleft lip with or without cleft palate in the offspring of women who smoke during pregnancy observed in this study is in line with previous evidence. In contrast to some previous studies, an increased risk was also apparent for cleft palate. In these U.K. data, there was evidence of a dose-response effect of maternal smoking for both types of cleft. The data were compatible with a modest effect of maternal passive smoking, but the study lacked statistical power to detect or exclude such an effect with confidence. It may be useful to incorporate information on the effects of maternal smoking on oral clefts into public health campaigns on the consequences of maternal smoking.
