Epidemiological and clinical parameters according to the Parker-Palmer Index (PPI) have not been specifically studied as predictors of re-fracture time in patients over 65years old with contralateral hip fracture. The main purpose of this study was to assess whether these parameters could represent a prognostic factor in this population.

This retrospective study included all consecutive patients older than 65years that suffered from a proximal femoral fracture, 31 according to Association for Osteosynthesis/Orthopaedic Trauma Association classification, treated at our unit between Feb 1st 2019 and Feb 1st 2020.

This study enrolled 387 patients. Thirty-seven of them had already incurred a contralateral hip fracture seven males and 30 females. The median time between the first and second hip fractures was 3.5years. This study revealed that increasing age (p = 0.003), male sex (p = 0.029) and a PPI value ≥ 5 between the first and second hip fracture (p = 0.015) are risk factors associated with a contralateral hip fracture in the first three years after the first episode. There were no statistically significant differences regarding anti-osteoporotic therapy and the anatomic site of the first hip fracture episode.

The results of the present study suggest that several risk factors have a crucial role in hip re-fracture time in patients over 65years old.

Herein, we identified a homozygous deletion mutation (507 del C) resulting in a frameshift (N170I) and early stop codon in the fungal binding Dectin-2 receptor, in an immunocompromised patient. The mutated form of Dectin-2 was weakly expressed, did not form clusters at/near the cell surface and was functionally defective. PBMCs from this patient were unable to mount a cytokine (TNF, IL-6) response to A. fumigatus and this first identified Dectin-2-deficient patient succumbed to invasive aspergillosis.Genomic information has a limited dimensionality (number of independent chromosome segments [Me]) related to the effective population size. Under the additive model, the persistence of genomic accuracies over generations should be high when the nongenomic information (pedigree and phenotypes) is equivalent to Me animals with high accuracy. The objective of this study was to evaluate the decay in accuracy over time and to compare the magnitude of decay with varying quantities of data and with traits of low and moderate heritability. The dataset included 161,897 phenotypic records for a growth trait (GT) and 27,669 phenotypic records for a fitness trait (FT) related to prolificacy in a population with dimensionality around 5,000. The pedigree included 404,979 animals from 2008 to 2020, of which 55,118 were genotyped. Two single-trait models were used with all ancestral data and sliding subsets of 3-, 2-, and 1-generation intervals. Single-step genomic best linear unbiased prediction (ssGBLUP) was used to compute genomic estimated breeding values (GEBV). Estimated accuracies were calculated by the linear regression (LR) method. The validation population consisted of single generations succeeding the training population and continued forward for all generations available. The average accuracy for the first generation after training with all ancestral data was 0.69 and 0.46 for GT and FT, respectively. The average decay in accuracy from the first generation after training to generation 9 was -0.13 and -0.19 for GT and FT, respectively. The persistence of accuracy improves with more data. Old data have a limited impact on the predictions for young animals for a trait with a large amount of information but a bigger impact for a trait with less information.

Compliance and tolerance of facemasks for extended periods are legitimate concerns. The goal of this study was to identify the physiologic and symptomatic effects of extended-use N95 filtering facepiece respirator (N95) compared with medical masks. We hypothesized that hospital personnel wearing medical masks alone would report fewer subjective complaints compared with personnel wearing an N95 with or without overlying medical mask.

This was a nonrandomized cohort study of hospital-based healthcare personnel at a single tertiary center wearing a medical mask alone or N95 with or without overlying medical mask during routine clinical activity. Potential subjects were consented and asked to complete a structured survey, including a 10-point Likert scale for subjective symptoms headache, lightheadedness, breathlessness, facial bruising, facial irritation, mental fatigue, physical fatigue, and yawning. Study investigators also obtained vital signs on the participants. Results between subjects wearing a medical mask and subjects wearing an N95 were compared. A sample of 144 subjects, 72 in each mask cohort, was needed to detect a 20% difference in a composite outcome of headache, shortness of breath, or lightheadedness between groups with an alpha of 0.05 and power of 0.8.

We enrolled 72 subjects in each group. There were no differences in baseline demographics. Overall 77% of the cohort reported subjective symptoms while donning a mask. There was no difference in the composite outcome, no difference recorded symptoms except facial bruising, and no difference in physiologic measures between groups.

Most medical mask and N95 users reported symptoms during mask use. However, there was no difference in the symptom proportion or severity in either user.

The corresponding heterogeneity in underlying patho-mechanisms of the disease has resulted in an impetus towards an endotype-driven management of AD. We propose a practical approach that is based on classifying AD patients into intrinsic and extrinsic phenotypes and their corresponding underlying endotypes. This approach aims to provide a practical method that integrates recent understanding of AD pathogenesis for a targeted endotype-driven management of AD.

Practice guidelines advise caution on the use of metformin in patients with type 2 diabetes mellitus with chronic kidney disease (CKD). This review aims to examine the evidence for the benefits and risks of metformin use in patients with T2DM and CKD.

The Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials and PubMed were searched; the references of selected papers were hand searched. Systematic reviews, randomised controlled trials, cohort studies, case series and case-control studies were included. The full text of selected articles was reviewed. The outcomes studied were all-cause mortality, cardiovascular complications, lactic acidosis and worsening of renal function. Recommendations were graded according to the Scottish Intercollegiate Guidelines Network system.

A total of 139 unique articles were identified, 14 of which met the inclusion criteria and were selected for full-text review. Four cohort studies reported an association between metformin use and improved all-cause mortality in CKD stage 4 and better. Two cohort studies reported improved cardiovascular outcomes with metformin use. Four cohort studies, 1 case series and 1 case-control study reported no significant association between metformin use and an increased risk of lactic acidosis in CKD. There is a moderate level of evidence to support reduced mortality, improved cardiovascular outcomes and a low risk of lactic acidosis with metformin use in patients with T2DM and with CKD stage 4 and above.

Existing recommendations to restrict metformin use in diabetes patients with CKD need to be reviewed in light of emerging evidence supporting its overall benefits in these patients.

Primary healthcare providers play a crucial role in educating their patients on chronic disease self-management (CDSM). this website This study aims to evaluate CDSM competency and satisfaction in patients receiving their healthcare from public or private healthcare providers.

A cross-sectional household study was conducted in a public housing estate using a standardised questionnaire to interview Singaporeans and permanent residents aged 40 years and above, who were diagnosed with at least 1 of these chronic diseases hyperlipidaemia, hypertension or diabetes mellitus. CDSM competency was evaluated with the Partners In Health (PIH) scale and a knowledge based questionnaire. Satisfaction was evaluated using a satisfaction scale.

In general, the 420 respondents demonstrated good CDSM competency, with 314 followed up at polyclinics and 106 by general practitioners (GPs). There was no significant difference between patients of polyclinics and GPs in CDSM competency scores (mean PIH score 72.9 vs 75.1, P=0.563), hypertension knowledge scores (90.9 vs 85.4, P=0.16) and diabetes knowledge scores (84.3 vs 79.5, P=0.417), except for hyperlipidaemia knowledge scores (78.6 vs 84.7, P=0.043). However, respondents followed up by GPs had higher satisfaction rates than did those followed up at polyclinics (odds ratio 3.6, confidence interval 2.28-5.78). Favourable personality of the doctors and ideal consultation duration led to higher satisfaction in the GP setting. A longer waiting time led to lower satisfaction in the polyclinic group.

Polyclinics and GPs provide quality primary care as evidenced by high and comparable levels of CDSM competency. Redistribution of patients from public to private clinics may result in improvements in healthcare service quality.

Flexible bronchoscopic intubation (FBI) is an important technique in managing an anticipated difficult airway, yet it is rarely performed and has a steep learning curve. We aim to evaluate if the integration of virtual reality gaming application into routine FBI training for emergency department doctors would be more effective than traditional teaching methods.

We conducted a randomised controlled trial to compare self-directed learning using the mobile application, Airway Ex* in the intervention group versus the control group without use of the mobile application. All participants underwent conventional didactic teaching and low-fidelity simulation with trainer's demonstration and hands-on practice on a manikin for FBI. Participants randomised to the intervention arm received an additional 30 minutes of self-directed learning using Airway Ex, preloaded on electronic devices while the control arm did not. The primary outcome was time taken to successful intubation.

Forty-five physicians (20 junior and 25 senior physicians) were enrolled, with male predominance (57.
