Abstract Immunization is an effective and proven tool for controlling and eliminating life-threatening vaccine preventable infectious diseases. In Ethiopia 5% of childhood mortalities are due to measles. In 2015, 85% of children had received 1 dose of measles vaccine by their second birthday. Despite the availability of a safe and effective vaccine, measles outbreaks secondary to non-vaccination are occurring in southern Ethiopia especially in Yirgachefe district.This study was done to assess the risk factors associated with non-vaccination against measles. A Community-based unmatched case control study was conducted in Yirgachefe district from December 1-31, 2016.Cases were defined as children in the age group of 12- 23 months of age who did not take measles vaccination. The study was done in 6 randomly selected kebeles and cases and controls were selected randomly by probability proportional to size sampling. A structured questionnaire was used for data collection and data was analyzed by using Epi info version 7 and SPSS version 20. Statistical significance was interpreted using Odds ratio with 95% confidence interval and P value <0.05. A total of 320 individuals (107 cases and 214 controls) were approached for interview with a response rate of 93.75%. Of the cases, 57% were males and more than half fall in the 12-18 months age group. Lack of Ante Natal Care follow up (Adjusted Odds Ratio (AOR) =3.57; 95% Confidence Interval (CI): 1.22-10.44), lack of knowledge on the importance of vaccination, who should be vaccinated and if measles is contagious with an AOR and CI of (AOR=6.81; 95% CI: 1.56-29.64), (AOR=4.29; 95% CI: 1.83-10.04) and (AOR=8.97; 95%CI: 3.15-25.58) respectively were independent risk factors. Lack of ANC follow up, lack of knowledge about who should get vaccinated, the importance of vaccination and contagiousness of the disease were identified as risk factors for non-vaccination against measles. Education and awareness about measles and its immunization should be given to the community. Additionally, ANC follow up should also be strengthened.

Study design: Retrosepctive analysis of prospectively collected data from the multicentre Canadian Surgical Spine Registry (CSORN). Objective: Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in North America. Few studies have evaluated return to work (RTW) rates after DCM surgery. Our goals were to determine rates and factors associated with postoperative RTW in surgically managed patients with DCM. Methods: Data was derived from the prospective, multicenter Canadian Spine Outcomes and Research Network (CSORN). From this cohort, we included all nonretired patients with at least 1-year follow-up. The RTW rate was defined as the proportion of patients with active employment at 1 year from the time of surgery. Unadjusted and adjusted analyses were used to identify patient characteristics, disease, and treatment variables associated with RTW. Results: Of 213 surgically treated DCM patients, 126 met eligibility, with 49% working and 51% not working in the immediate period before surgery; 102 had 12-month follow-up data. In both the unadjusted and the adjusted analyses working preoperatively and an anterior approach were associated with a higher postoperative RTW ( P < .05), there were no significant differences between the postoperative employment groups with respect to age, gender, preoperative mJOA (modified Japanese Orthopaedic Association) score, and duration of symptoms ( P > .05). Active preoperative employment (odds ratio = 15.4, 95% confidence interval = 4.5, 52.4) and anterior surgical procedures (odds ratio = 4.7, 95% confidence interval = 1.2, 19.6) were associated with greater odds of RTW at 1 year. Conclusions: The majority of nonretired patients undergoing surgery for DCM had returned to work 12 months after surgery; active preoperative employment and anterior surgical approach were associated with RTW in this analysis.

The purpose of the study was to investigate the natural history of insomnia and its association with depression and mortality. In 1983, 1,870 randomly selected subjects aged 45–65 years answered a questionnaire on sleep and health. Of the 1,604 survivors in 1995, 1,244 (77.6%) answered a new questionnaire with almost identical questions. Mortality data were collected for the 266 subjects that had died during the follow-up period. Chronic insomnia was reported by 36.0% of women and 25.4% of men (χ2 = 9.7; p < .01). About 75% of subjects with insomnia at baseline continued to have insomnia at follow-up. Insomnia in women predicted subsequent depression (odds ratio [OR] = 4.1; 95% confidence interval [CI] 2.1–7.2) but was not related to mortality. In men, insomnia predicted mortality (OR = 1.7; 95% CI 1.2–2.3), but after adjustment for an array of possible risk factors, this association was no longer significant. Men with depression at baseline had an adjusted total death rate that was 1.9 times higher than in the nondepressed men (95% CI: 1.2–3.0).

Objectives The objective was to evaluate factors associated with euthanasia in an animal shelter in Kitchener-Waterloo, Ontario, Canada. Methods Data from 3737 cats admitted to the shelter between January and December 2011 were evaluated. Results Overall, 1989/3737 (53%) of admitted cats were euthanized. Male cats had greater odds of being euthanized than females (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.29–2.05; P <0.001) and surrendered cats were more likely to be euthanized than strays (OR 38.0, 95% CI 14.8–97.69; P <0.001). Black cats were more likely to be euthanized than cats of another color (OR 1.45, 95% CI 1.16–1.80; P <0.001). Cats that spent >5 days in the shelter were more likely to be euthanized than those that spent <5 days in the shelter (OR 1.57, 95% CI 1.25–1.97; P <0.001). Cats that spent >20 days in the shelter were less likely to be euthanized than those that spent <5 days in the shelter (OR 0.26, 95% CI 0.19–0.34; P <0.001). Age, an age quadratic term, neuter status and interactions among these variables were statistically significant; the odds of unneutered animals being euthanized was high and relatively stable across age groups, but in neutered animals the odds of being euthanized increased with age before plateauing in older cats. Conclusions and relevance With >50% of the cats admitted to the shelter in 2011 euthanized, it is important to understand the contributing risk factors that predispose shelter cats to euthanasia and what changes can be made to the shelter system and in owner education to lower the incidence of euthanasia.

Background and objectives: Vulvovaginal candidiasis is known to be a global issue of concern due to its association with economic costs, sexually transmitted diseases, and the escalation of genital tract infections.  This study aimed to determine the prevalence, species distribution and risk factors associated with Candida species causing vulvovaginal candidiasis. Subjects and Methods:  Non-pregnant women attending routine antenatal visits at Al-Olaifi-Family Center in Sana'a were enrolled in a cross-sectional study conducted from June 2018 to March 2019. Laboratory work was carried out at the National Center of Public Laboratories (NCPHL). Vaginal swabs were sampled from participants after oral consent was obtained. The swabs were inoculated in Sabouraud glucose agar supplemented with chloramphenicol and incubated at 37°C for 24 to 48 h under aerobic conditions in order to perform a fungal culture. Candida species were determined by culturing on HiCrome Candida differential Agar at 35°C for 48 h to produce species-specific colours. Data on demographic, clinical, and risk factors were collected in a pre-designed questionnaire. Results:  A total of 190 non-pregnant women were included. The prevalence of VVC was 22.1%. Candida albicans accounted for 16.3% and non-Candida albicans accounted for 5.8% of the isolates, mainly C. glabrata (3.2%), C. rugosa (1.05%), C. lipolytica (1.05%), and C. dubliniensis (0.53%). When VVC risk factors were considered, there were significant risk factors with age group 30-34 years (33.3%, odds ratio=2.1) and age group  ≥35 years (62.5%, odds ratio=10.3), residence in a rural area (39.5 %, OR=3.3), negative emotions (30.2%, OR=2.3), underwear replacement over 1 day (29.3%, OR=4.2), impure cotton underwear (29.4%, OR=4.9), while Condom use and vulvar cleaning before or after sexual life were found to be highly significant protective factors against VVC (p=0.008, 0.03, respectively). Conclusions: Guidelines for the management of VVC syndrome in Yemen should be revised to include a protocol specifically for women over 30 years of age. VVC undoubtedly poses a significant threat to women's reproductive health. Risk factors for VVC are varied, and include ages, health habits, history of the disease, and other aspects. It is necessary to take appropriate measures to avoid risk factors and to help reduce the prevalence of VVC among women of childbearing age.                    Peer Review History: Received: 3 May 2021; Revised: 23 June; Accepted: 30 June, Available online: 15 July 2021 Academic Editor: Dr. Ali Abdullah Al-yahawi, Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Objectives: Pediatric sinus surgery is indicated for a wide range of sinonasal and skull base pathologies, but it is most commonly performed for recalcitrant chronic rhinosinusitis or complicated acute sinusitis. The authors aim to report medical risk factors of morbidity and mortality following inpatient sinus surgery in the pediatric population. Methods: Using data from the Kids’ Inpatient Database from 2003 to 2012, patients with International Classification of Diseases, Ninth Revision, procedure codes for primary sinus surgery were identified. Mixed-effect multivariable logistic regression was used to identify risk factors of inpatient postoperative morbidity and mortality. Results: The final sample included a weighted estimate of 4965 pediatric patients. The rates of inpatient morbidity and mortality were 6% and 1%, respectively. Respiratory complications (2.5%) were the most prevalent postoperative adverse events. The most prevalent comorbidities were chronic sinusitis (59.8%), acute sinusitis (27.8%), and cystic fibrosis (26.4%). Compared with patients who did not experience any morbidity, patients with inpatient morbidity had higher rates of pneumonia, mycoses, and nasal or paranasal benign neoplasm ( P < .05). The odds of inpatient morbidity and mortality were highest for patients with leukemia (odds ratio, 2.74; 95% confidence interval, 1.59-4.72; P < .001) and mycoses (odds ratio, 15.84; 95% confidence interval, 6.45-38.89; P < .001), respectively. Conclusions: This study is the first to report the national comorbidity burden and risk factors for postoperative adverse events following inpatient sinus surgery. Knowledge of the comorbidities and independent factors associated with morbidity and mortality will help in directing preoperative optimization and counseling. Level of Evidence: 2c

AbstractObjectives:This study aimed to determine the prevalence of vestibular dysfunction in the Singaporean elderly and its association with presbyacusis, age and other associated risk factors.Methods:A cross-sectional study was undertaken in a tertiary otorhinolaryngology department and the community. Healthy adults aged 40 years and above who participated in the institution's community presbyacusis screening programme were invited to participate. The main outcome measures including pure tone audiometry and vestibular assessment were obtained using a modified Clinical Test of Sensory Interaction on Balance.Results:The prevalence of vestibular dysfunction and presbyacusis in the study population of 216 participants was 30.1 per cent (95 per cent confidence interval, 24.0 to 36.2 per cent) and 55.6 per cent (95 per cent confidence interval, 49.0 to 62.2 per cent), respectively. The median age was 60 years (range, 40–86 years). The adjusted odds ratio for vestibular dysfunction increased by 6.2 per cent with every year of life (p < 0.05), and by 3.14 times in the presence of presbyacusis (p < 0.05). After adjusting for age and presbyacusis, diabetes (n = 30), hypertension (n = 85), hypercholesteraemia (n = 75), cardiac disease (n = 14), stroke (n = 7) and smoking (n = 55) were associated with an increased odds ratio for vestibular dysfunction which did not reach statistical significance (p > 0.05).Conclusion:Vestibular dysfunction is independently associated with ageing and presbyacusis. Further research into the benefits of additional screening for vestibular dysfunction in elderly presbyacusis patients is warranted.

Goats can be infected by multiple groups of external and internal parasites. Haemonchus spp. are among abomasal parasites that can result in higher mortality and several considerable economic losses in goats. Early detection of parasites and better understanding of the major risk factors associated with infection are among the main strategies for controlling the infection. Considering this, information on hemonchosis in goats from Egypt, and the contribution of goats in the maintenance of the epidemiological foci of the disease is limited. This study investigated the prevalence of Haemonchus species among 240 abomasum samples collected during postmortem examination of goat carcasses from Assiut Governorate, Egypt. Moreover, the association of the major risk factors to describe the epidemiological pattern of the disease was explored. This study demonstrated that 16.66% of abomasa samples harbored Haemonchus species. Additionally, age, sex, and sampling season were the most significant risk factors associated with infection. Following the variable factors under study, goats aged 1 year or older were at higher risk, with an infection rate of 22.14% (31 of 140), than those younger than 1 year (9%) [p = 0.008; odds ratio (OR) = 2.87; 95% confidence interval (CI), 1.30–6.35]. The infection rate was 25% (19 of 76) in males and 12.8% (21 of 164) in females [p = 0.024; odds ratio (OR) = 2.26; 95% confidence interval (CI), 1.13–4.53]. Moreover, the exposure to infection was higher in summer (22.22%) than in winter (8.33%) (p = 0.007; odds ratio (OR) = 0.318; 95% confidence interval (CI), 0.139–0.725). More importantly, three species of the parasite—Haemonchus contortus, Haemonchus placei, and Haemonchus longistipes—were identified for the first time, and the confirmation of the identification and morphological characterization of the worms was performed using light microscopy and SEM. Collectively, this study reveals interesting epidemiological, morphological, and morphometric findings associated with the occurrence of hemonchosis among goats in Egypt. This study suggests further research for exploring the major circulating species of the parasite in Egypt, which is mandatory for controlling the disease.

AbstractObjectivesTo establish the prevalence of hypocalcaemia following laryngectomy and demonstrate that total thyroidectomy is a risk factor.MethodsA retrospective cohort study was conducted that included all patients who underwent total laryngectomy from 1st January 2006 to 1st August 2017. Exclusion criteria were: pre-operative calcium derangement, previous thyroid or parathyroid surgery, concurrent glossectomy, pharyngectomy, or oesophagectomy.ResultsNinety patients were included. Sixteen patients had early hypocalcaemia (18 per cent), seven had protracted hypocalcaemia (8 per cent) and six had permanent hypocalcaemia (10 per cent). Exact logistic regression values for hypocalcaemia following total thyroidectomy compared to other patients were: early hypocalcaemia, odds ratio = 15.5 (95 per cent confidence interval = 2.2–181.9; model p = 0.002); protracted hypocalcaemia, odds ratio = 13.3 (95 per cent confidence interval = 1.5–117.1; model p = 0.01); and permanent hypocalcaemia, odds ratio = 22.7 (95 per cent confidence interval = 1.9–376.5; model p = 0.005).ConclusionThis is the largest study to investigate the prevalence of hypocalcaemia following laryngectomy and the first to include follow up of longer than three months. Total thyroidectomy significantly increased the risk of hypocalcaemia at all time frames and independent of other variables.
