To infer the causality between obesity and fracture and the difference between general and abdominal obesity, a prospective study was performed in 456,921 participants, and 10,142 participants developed an incident fracture with follow-up period of 7.96 years. A U-shape relationship was observed between BMI and fracture, with the lowest risk of fracture in overweight participants. 

Molar pregnancy is the most common type of gestational trophoblastic disease. Several recent reports have described changes in the clinical representation, the incidence and the diagnostic sensitivity of molar pregnancy. These changes could be due to widespread use of transvaginal ultrasound and beta-hCG testing in the management of routine first-trimester investigations. This is a retrospective study of 144 women diagnosed with partial or complete mole at a regional medical center during 2007-2020.

The association of vitiligo with psoriasis is inconsistent in the current literature. Assess the bidirectional association between vitiligo and psoriasis.

The association of autoimmune bullous diseases (AIBDs) with thyroid disorders remains to be profoundly investigated. Evaluates the epidemiological association between six AIBDs and thyroid disorders.

Promoting healthy lifestyle is key to tackling lifestyle-induced diseases, yet many doctors feel unskilled and medical schools lack its inclusion in their curricula. The impact of a novel elective lifestyle course is described, where students provided 3 months' coaching to at-risk patients.

Limited data exist regarding the significance of peripheral arterial disease (PAD) in patients with acute coronary syndrome (ACS). We evaluated 16,922 consecutive ACS patients who were prospectively included in a national ACS registry. The co-primary endpoint included 30 days major adverse cardiovascular event (MACE) (re-infarction, stroke, and/or cardiovascular death) and 1-year mortality.

Changing patterns of vaccine breakthrough can clarify vaccine effectiveness. Compares breakthrough infections during a SARS-CoV-2 Delta wave vs unvaccinated inpatients, and an earlier Alpha wave.

Pulmonary hypertension (PHT) may complicate heart failure with reduced ejection fraction (HFrEF) and is associated with a substantial symptom burden and poor prognosis. Sildenafil, a phosphodiesterase-5 (PDE-5) inhibitor, might have beneficial effects on pulmonary haemodynamics, cardiac function and exercise capacity in HFrEF and PHT. Determines the safety, tolerability, and efficacy of sildenafil in patients with HFrEF and indirect evidence of PHT.

The use of medical cannabis (MC) to treat cancer-related symptoms is rising. However, there is a lack of long-term trials to assess the benefits and safety of MC treatment in this population. In this work, we followed up prospectively and longitudinally on the effectiveness and safety of MC treatment.

Symptoms related to abnormalities in gastrointestinal tract motility and functions are very common in the general population, affecting both pediatrics and adults, from both sexes [...]. Editorial

Heart failure (HF) affects >6 million adults in the United States1 and 26 million worldwide2, at a cost of over $30 billion in the United States alone3. Pulmonary congestion is the predominant factor leading to hospitalisation for HF patients, and also is a major contributor to poor outcomes after hospital discharge. A need exists for a simple, non-invasive approach to detecting worsening pulmonary congestion at an early stage for the management of HF patients. In the context of pulmonary congestion, it has been proposed that the fluid overload may be detected by distinctly altered phonation patterns.

Despite intensive efforts, there is no effective remedy for COVID-19. Moreover, vaccination efficacy declines over time and may be compromised against new SARS-CoV-2 lineages. Therefore, there remains an unmet need for simple, accessible, low-cost and effective pharmacological anti-SARS-CoV-2 agents. ArtemiC is a medical product comprising artemisinin, curcumin, frankincense and vitamin C, all of which possess anti-inflammatory and anti-oxidant properties. The present Phase II placebo-controlled, double-blinded, multi-centred, prospective study evaluated the efficacy and safety of ArtemiC in patients with COVID-19. 

It is important to define the accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis of Warthin tumor (WT). This systematic review and meta-analysis evaluated the accuracy of FNAC in the diagnosis of WT in the parotid gland and WT growth rate.

Cleft lip and/or cleft palate are a common group of birth defects that further classify into syndromic and non-syndromic forms. The syndromic forms are usually accompanied by additional physical or cognitive abnormalities. Isolated cleft palate syndromes are less common; however, they are associated with a variety of congenital malformations and generally have an underlying genetic etiology. A single report in 2019 described a novel syndrome in three individuals, characterized by cleft palate, developmental delay and proliferative retinopathy due to a homozygous non-sense mutation in the LRRC32 gene encoding glycoprotein A repetitions predominant (GARP), a cell surface polypeptide crucial for the processing and maturation of transforming growth factor β (TGF-β). We describe a patient who presented with cleft palate, prenatal and postnatal severe growth retardation, global developmental delay, dysmorphic facial features and progressive vitreoretinopathy.

In 1966, Andreasen and Hjørting-Hansen were the first to describe a relationship between tooth resorption and dental trauma. However, Andreasen's original classification did not include other resorptive processes which have since been identified. Numerous articles have been published suggesting new terminology and definitions for tooth resorption. A uniform language with universally accepted terminology is crucial to eliminate the multiplicity of terms and definitions which only cause confusion within the profession. An electronic literature search was carried out in the PubMed database using the following keywords for articles published in English: "root resorption," "inflammatory root resorption," "replacement resorption," "cervical resorption," "trauma," "ankylosis," "surface resorption," and "internal resorption." The search also included textbooks and glossaries that may not have surfaced in the online search. This was done to identify articles related to tooth resorption and its etiology in dentistry. The aim of this review was to present the history that has led to the variety of terms and definitions for resorption.
