The main objective of this study was to compare the clinical and histological results of synthetic bone substitutes used in maxillary sinus floor augmentation. A systematic review and meta-analysis was performed by searching the PubMed/MEDLINE, Scopus, and Cochrane databases for studies of the success of endosseous dental implant, implant failure, peri-implant marginal bone loss, newly formed bone, and residual bone graft material. After the search, 10 randomized clinical trials were included, with 4 studies ranging from low to unclear risk of bias were used for meta-analysis, comparing biphasic calcium phosphate (BCP) and deproteinized bovine bone (DBB). A greater amount of residual graft material (mean difference [MD]: -4.80 mm; 95% CI: -9.35 to -0.26; P = .040) was found in the DBB group. No other statistically significant differences were found between BCP and DBB for the remaining outcomes. Our results suggested that BCP can be considered a suitable alternative to DBB in maxillary sinus floor augmentation due to its clinical and histological results.

Importance: Sensitivity to environmental stress and adversity may influence lung cancer risk, highlighting a critical link between psychosocial factors and cancer etiology.
Objective: To evaluate whether genetically estimated sensitivity to environmental stress and adversity is associated with lung cancer risk.
Design, Setting, And Participants: Data were obtained from a genome-wide association study identifying 37 independent genetic variants strongly associated with sensitivity to environmental stress and adversity and a cross-ancestry genome-wide meta-analysis from the International Lung Cancer Consortium.

Background: Interest in noninvasive treatment of basal cell carcinoma (BCC) has been increasing. For superficial BCC, it has been demonstrated that imiquimod cream, 5%, has high long-term efficacy, but for nodular BCC (nBCC), long-term evidence is sparse.
Objectives: To evaluate whether superficial curettage (SC) followed by imiquimod cream, 5%, is noninferior to surgical excision (SE) in nBCC after 5 years of treatment.

Exaggerated neuronal excitation by glutamate is a well-known cause of excitotoxicity, a key factor in numerous neurodegenerative disorders. This study examined the neurotoxic effect of monosodium glutamate (MSG) in the brain cortex of rats and focused on assessing the potential neuroprotective effects of omega-3 polyunsaturated fatty acids (ω-3 PUFAs). Four groups of adult male rats (n = 10) were assigned as follows; normal control, ω-3 PUFAs (400 mg/kg) alone, MSG (4 mg/g) alone, and MSG plus ω-3 PUFAs (4 mg/g MSG plus 400 mg/kg ω-3 PUFAs).

Current guidelines to prevent hepatocellular carcinoma (HCC) by chronic hepatitis B virus (HBV) infection are based on risk assessments that include age, sex, and virological and biochemical parameters. The study aim was to investigate the impact of predictive markers on long-term outcomes. The clinical outcomes of 100 patients with chronic hepatitis B were investigated 30 years after a baseline assessment that included liver biopsy.

Cardiac amyloidosis (CA) is an infiltrative disease that results from the deposition of amyloid fibrils in the myocardium, resulting in restrictive cardiomyopathy. The amyloid fibrils are predominantly derived from two parent proteins, immunoglobulin light chain (AL) and transthyretin (ATTR), and ATTR is further classified into hereditary (ATTRv) and wild-type (ATTRwt) based on the presence or absence, respectively, of a mutation in the transthyretin gene. Once thought to be a rare entity, CA is increasingly recognized as a significant cause of heart failure due to improved clinical awareness and better diagnostic imaging.
