In this study, we examined whether combining neoadjuvant chemotherapy (NAC) and/or concurrent chemotherapy (CC) with intensity-modulated radiotherapy (IMRT) improved survival in patients with stage II nasopharyngeal carcinoma (NPC). Two hundred forty-two stage II NPC patients were enrolled between May 2008 and April 2014 and received radical IMRT with simultaneous integrated boost technique using 6 MV photons; some patient groups also received chemotherapy every 3 weeks for 2-3 cycles. The median follow-up duration was 69 months for all patients. At the last follow-up, 18 patients had experien

The 2019 Coronavirus Disease (COVID-19) has become an unprecedented public crisis. We retrospectively investigated the clinical data of 197 COVID-19 patients and identified 88 patients as disease aggravation cases. Compared with patients without disease aggravation, the aggravation cases had more comorbidities, including hypertension (25.9%) and diabetes (20.8%), and presented with dyspnoea (23.4%), neutrophilia (31.5%), and lymphocytopenia (46.7%). These patients were more prone to develop organ damage in liver, kidney, and heart (P < 0.05). A multivariable regression analysis showed that adv

Background: Chronotype is the pattern of the circadian rhythm that allows an individual to optimize times of sleep and activity. It has been observed that chronotypes may associate with some conditions and diseases, including obesity. It is not known, however, whether chronotypes determine the effectiveness of weight loss regimens. Therefore, in the present study, we compared the outcomes of a 3-week moderate calorie restriction undertaken by individuals with obesity under the same controlled hospital conditions. Methods: A total of 131 participants with obesity (median BMI 40.0) were studied.

Cardiovascular toxicity is the most common cause of fatality in the first 24 hours of poisoning with aluminium phosphide (AlP). Most often manifesting itself in cardiac dysrhythmias. The aim of this study was to evaluate the benefits of amiodarone prophylaxis against cardiac dysrhythmia in 46 patients with acute AlP poisoning. They were divided in two groups of 23: one receiving amiodarone and the other not (control). The treatment group received amiodarone prophylaxis in the initial intravenous bolus dose of 150 mg, followed by a drip of 1 mg/min for six hours and then of 0.5 mg/min for eight

Abstract Co-pathology is frequent in Lewy body disease, which includes clinical diagnoses of both Parkinson’s disease and dementia with Lewy bodies. Measuring concomitant pathology in vivo can improve clinical and research diagnoses and prediction of cognitive trajectories. Tau PET imaging may serve a dual role in Lewy body disease by measuring cortical tau aggregation as well as assessing dopaminergic loss attributed to binding to neuromelanin within substantia nigra. We sought to characterize 18F-PI-2620, a next generation PET tracer, in individuals with Lewy body disease. We recruited 141 p

Short-chain fatty acids (SCFAs) are metabolites derived from the fermentation of dietary fibre by gut bacteria. SCFAs function as essential regulators of host-microbiome interactions by participating in numerous physiological and pathological processes within the gastrointestinal (GI) tract. In recent years, the depletion of SCFAs has been increasingly linked to the pathogenesis of GI diseases. In this review, we summarize the current understanding of the therapeutic mechanisms of SCFAs in GI diseases, including inflammatory bowel disease, irritable bowel syndrome, metabolic dysfunction-associ

Abstract Nociceptive pain is a cardinal feature of traumatic and inflammatory bone diseases. However, whether and how nociceptors actively regulate the immune response during bone regeneration remains unclear. Here, we found that neutrophil-triggered nociceptive ingrowth functioned as negative feedback regulation to inflammation during bone healing. A unique Il4ra + Ccl2 high neutrophil subset drove intense postinjury TRPV1 + nociceptive ingrowth, which in return dissipated inflammation by activating the production of pro-resolving mediator lipoxin A4 (LXA4) in osteoblasts. Mechanistically, os

Vitamin D, long recognized for its essential role in calcium-phosphate balance and bone health, has increasingly been identified as a pleiotropic regulator of metabolic, cardiovascular, and renal function. Deficiency of vitamin D is widespread worldwide and has been linked to a higher risk of insulin resistance, type 2 diabetes, atherosclerosis, hypertension, and chronic kidney disease. Meta-analyses suggest that each 10 nmol/L (≈4 ng/mL) increase in serum 25-hydroxyvitamin D [25(OH)D] is associated with about a 4% lower risk of type 2 diabetes, whereas other analyses indicate an approximately

Much is known about the use, benefits, and side-effects, of clozapine in treatment resistant schizophrenia (TRS). However, why clozapine is more effective than other antipsychotics in TRS remains unclear. This paper addresses this question. TRS patients show glutamate abnormalities, and clozapine has widespread effects on glutamate. However, these actions have not been proven different to those of other antipsychotics. Immune dysfunction is also reported in TRS, and clozapine has anti-inflammatory actions, but these have not been correlated with clinical improvement. Currently, there is much i
