Introduction: Obesity is a major public health concern. Accurate perception of body weight may be critical to the successful adoption of weight loss behavior. The aim of this study was to determine the accuracy of self-perception of BMI class. Methods: Patients admitted to the acute medical service in one regional hospital completed a questionnaire and classified their weight as: “underweight,” “normal,” “overweight,” or “obese.” Reponses were compared to clinically measured BMIs, based on the WHO Classification. Patients were also questioned about health-related behavior. Data were analyzed via Pearson’s Chi-squared test. Results: Almost 70% of the participating patient population (n = 90) incorrectly perceived their weight category, with 62% underestimating their weight. Only 34% of patients who were overweight and 14% of patients with obesity correctly identified their weight status. Two-thirds of patients who were overweight and one-fifth of patients with obesity considered themselves to be “normal” or “underweight.” Patients with obesity were 6.5-fold more likely to misperceive their weight status. Amongst patients with overweight/obesity, those who misperceived their weight were significantly less likely to have plans to lose weight. Almost 60% had not made any recent health behavior changes. This is one of the first regional Australian studies demonstrating that hospitalized patients significantly misperceive their weight. Conclusion: Patients with overweight/obesity had significantly higher rates of weight misperception and the majority had no intention to lose weight or to undertake any health behavior modification. Given the association between weight perception and weight reduction behavior, it introduces barriers to addressing weight loss and reducing the increasing prevalence of obesity in rural Australia. It highlights that doctors have an important role in addressing weight misperception.

Complex regional pain syndrome type 1 (CRPS-I) is a devastating complication that can occur after limb extremity injuries. The effectiveness of vitamin C in preventing CRPS-I incidence is debatable. Therefore, we conducted a systematic review and meta-analysis to assess the role of vitamin C in CRPS-I prevention and its effect on pain score, functional outcomes and complications rate after wrist, ankle, and foot fractures.We searched Medline, Embase, the Cochrane Library, Clinicaltrial.gov, and Google Scholar from infinity to May 2021 for relevant studies comparing the incidence of CRPS-I with administration of perioperative vitamin C versus placebo after wrist, ankle, and foot fractures. Continuous data such as functional outcomes and pain scores were pooled as mean differences (MD), whist dichotomous variables such as the incidence of CRPS-I and complications were pooled as odds ratios (OR), with 95% confidence interval (CI). Data analyses was done using R software (meta package, version 4.9-0) for Windows.Eight studies, including two quasi-experimental studies, were included. The timeframe for vitamin C administration ranged from 42 to 50 days post-injury and/or surgical fixation and the dosage was either 500 mg or 1000 mg. The results showed that vitamin C was associated with a lower rate of CRPS-I relative to a placebo (OR 0.33, 95% CI [0.17, 0.63]). No significant difference was found between vitamin C and placebo in terms of complications (OR 1.90, 95% CI [0.99, 3.65]), functional outcomes (MD 6.37, 95% CI [-1.40, 14.15]), and pain scores (MD −0.14, 95% CI [-1.07, 0.79]).The findings demonstrate that when compared to placebo, at least 42 days of vitamin C prophylaxis is associated with prevention of CRPS-I following wrist, ankle, and foot fractures, irrespective of vitamin C dosage or fracture type. No significant differences were found with secondary outcomes.

To investigate association between keratoconus and allergic eye diseases, eye rubbing, and atopy.PubMed, Web of Science, Scopus, and Cochrane were searched for relevant published studies from inception to April 2021 without restrictions or filters. We included case-control, cohort, and cross-sectional studies that investigated eye allergy, atopy, or eye rubbing as possible risk factors for KC. Two authors independently screened all titles and abstracts against predefined inclusion and exclusion criteria. This study analysed keratoconus prevalence and risk factors including eye rubbing, family history of keratoconus, atopy, and allergic eye diseases. The National Institute of Health Study Quality Assessment tool was utilised. Pooled data were presented as odds ratio (OR) and 95% confidence intervals (CI). Analysis was conducted using RevMan version 5.3 software.Out of 573 articles, we excluded 161 duplicates than 361 articles by title and abstract screening. The remaining 51 articles underwent full-text screening, and 29 articles were excluded. Twenty-one studies were included in the qualitative synthesis and fifteen for quantitative synthesis. There was no significant association found between KC and allergic eye diseases (OR = 1.03, 95% CI [0.96, 1.11], p = 0.45), eye rubbing (OR = 1.59, 95% CI [0.70, 3.63], p = 0.27), or atopy (OR = 1.08, 95% CI [0.80, 1.44], p = 0.62).No significant association was observed between KC and allergic eye disease, eye rubbing, or atopy. Further prospective studies are needed to clarify and validate these findings.
