Abstract CONTEXT One of the risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is postulated to be vitamin D deficiency. To understand better the role of vitamin D deficiency in the disease course of COVID-19, we undertook a retrospective case-control study in the North West of England (NWE). OBJECTIVE To examine whether hospitalisation with COVID-19 is more prevalent in individuals with lower vitamin D levels. METHODS The study included individuals with results of serum 25-hydroxyvitamin D (25[OH]D) between 1 st April 2020 and 29th January 2021. Patients were recruited from two districts in NWE. The last 25(OH)D level in the previous 12 months was categorised as ‘deficient’ if less than 25 nmol/L and ‘insufficient’ if 25-50 nmol/L. RESULTS 80,670 participants were entered into the study. Of these, 1,808 were admitted to hospital with COVID-19, of whom 670 died. In a primary cohort, median serum 25(OH)D in participants who were not hospitalised with COVID-19 was 50.0 [interquartile range, IQR 34.0-66.7] nmol/L versus 35.0 [IQR 21.0-57.0] nmol/L in those admitted with COVID-19 (p <0.005). There were similar findings in a validation cohort (median serum 25(OH)D 47.1 [IQR 31.8-64.7] nmol/L in non-hospitalised versus 33.0 [IQR 19.4-54.1] nmol/L in hospitalised patients). Age-, sex- and seasonal variation-adjusted odds ratios for hospital admission were 2.3-2.4 times higher among participants with serum 25(OH)D <50 nmol/L, compared to those with normal serum 25(OH)D levels, without any excess mortality risk. CONCLUSIONS Vitamin D deficiency is associated with higher risk of COVID-19 hospitalisation. Widespread measurement of serum 25(OH)D and treating any unmasked insufficiency or deficiency through testing may reduce this risk.

The aim of this retrospective case-control study is to determine a possible correlation between breathing mode and craniofacial morphology. The study was carried out in the Department of Pedodontics,Iuliu Hatieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania. The sample comprised 80 patients, age between 6 and 13 years, which were divided in two groups based on respiratory pattern: control group composed of 38 nasal breathing children and case group composed of 42 oral breathing children. Three quantitative craniofacial parameters were measured from the frontal and lateral photos: facial index, lower facial height ratio and upper lip ratio. The statistical analysis showed a significant higher facial index (p=0.006*) and an increase lower facial height (p=0.033*) for the oral breathers group. No differences in facial morphology were found between genders and age groups, when comparing the data between the same type of respiratory pattern children. Spearman�s rho Correlation show a significant positive correlation (p=0.002*) between facial index and lower facial height and a significant negative correlation between facial index and upper lip (p=0,005*). Long faces children are more likely to develop oral breathing in certain conditions, which subsequently have a negative effect on increasing the lower facial height by altering the postural behavior of mandible and tongue.

Stroke is a major cause of disability worldwide, and balance impairments are common disabling factors in patients with stroke, leading to falls. Thus, the study objectives were as follows: (i) To find the prevalence of balance impairment among patients with stroke. (ii) To find out the factors associated with balance impairment in patients with stroke. This cross-sectional retrospective case control study involved eighty-one post stroke patients with a mean age of 58.36 ± 14.06, recruited from six hospitals, who underwent an assessment of balance, walking speed, depression and isometric strength of the ankle and knee. These patients were later categorized into subjects with good balance (<45) in the Berg balance scale (BBS) and those with poor balance (≥45), as cases and controls, to assess the factors associated with balance impairment using binary logistic regression. The prevalence of balance impairment among patients with stroke was 48.1%. The reduction in power of knee flexors (OR = 0.858), knee extensors (OR = 0.880) and ankle dorsiflexors (OR = 0.820) was found to be significantly associated with balance impairment, along with speed (OR = 1.187 (95% CI = 1.100, 1.280)), depression (OR = 1.331 (95% CI = 1.055–1.679)) and activities of daily living (OR = 0.313 (95% CI = 0.150–0.650)). In summary, around half of the patients with stroke exhibited balance impairments, with females being more prone.
