The efficacy of segmentectomy for inner small-sized non-small-cell lung cancer (NSCLC) remains unknown. We aimed to elucidate whether segmentectomy for inner small-sized NSCLC, defined using novel three-dimensional measuring method, yields feasible oncological outcomes compared to segmentectomy for outer lesions.

We retrospectively analyzed patients with small-sized (<2cm) cN0 NSCLC who underwent segmentectomy between January 2007 and December 2020. Tumor centrality ratio, which was measured by using three dimensional reconstruction software, was evaluated, with the location of tumor origin confirmed pathologically. Cases with a ratio below and above 2/3 were allocated to the 'Inner group' and 'Outer group', respectively. Oncological outcomes were compared between the two groups.

Our cohort was divided into the 'Inner group' (n=75) and 'Outer group' (n=127). The proximal distance from a tumor exceeded 20 mm in all cases. Tumor centrality ratio was associated with the pathological origin of a tumor. The rate of unforeseen positive lymph node metastasis was significantly higher in the 'Inner group' (p=0.04). There were no significant differences in the 5-year recurrence free survival (RFS; 91% versus 87%, p=0.67). Univariate analysis identified age, consolidation/tumor ratio, the presence of ground-glass-opacity (GGO) and lymphovascular invasion, but not tumor centrality, as significant prognostic factors for RFS. In the multivariate analysis, the presence of GGO and lymphovascular invasion remained significant.

Regarding oncological outcomes, segmentectomy with a safety proximal distance could be feasible, even for inner small-sized NSCLC. Tumor invasiveness, not tumor centrality, may influence tumor recurrence. (242 words).

Patients after heart transplantation are at increased risk for malignancy secondary to immunosuppression and oncogenic viral infections. M3541 Most common amongst children is post-transplant lymphoproliferative disorder (PTLD), occurring in 5-10% of patients. We utilized a national database to examine incidence and risk factors for post-transplant malignancy.

The United Network for Organ Sharing (UNOS) database was queried for pediatric (<18 years) heart transplant recipients from 10/1987-10/2019. Kaplan-Meier analysis was performed to assess freedom from malignancy post-transplant. Cox regression was performed to generate hazard ratios (HR [95% CI]) for risk of malignancy development.

Of 8,581 pediatric heart transplant recipients, 8.1% developed malignancy over median follow-up time of 6.3 years, with PTLD compromising the majority (86.4%) of diagnosed cancers. The incidence of PTLD development was 1.3% and 4.5% at one and five years. Older age at the time of transplant was protective against the developts, does not seem to increase post-transplant malignancy, nor does the most commonly used calcineurin inhibitor tacrolimus.
Meta-analytic comparison of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) versus percutaneous gallbladder drainage (PT-GBD) for acute cholecystitis (AC) brings the risk of spurious results if too few studies are included. Trial sequential analysis (TSA) can overcome this, providing information about its credibility.

Comparative studies between EUS-GBD, using lumen-apposing metal stents (LAMSs), and PT-GBD for AC until July 2021 were used for conventional meta-analysis and TSA, which allowed the use of monitoring boundaries and the estimation of the required information size (RIS) needed to prove credibility.

Four studies accrued 535 patients. Technical success was in favor of PT-GBD (relative risk [RR] 0.967; p=0.036) but TSA estimated that 1663 participants would be needed to avoid type 1 error (false positive). Clinical success was similar (RR, 0.965; p=0.146), and TSA supported the absence of any demonstrable superiority of one therapy, rather than a type 2 error (false negative). EUS-Gs additional studies.
Endoscopist recommendations around repeating colonoscopy after inadequate bowel cleanliness have not been fully described. Our aim was to evaluate the timing of recommendations for repeat colonoscopy after inadequate bowel preparation using a large, national colonoscopy registry.

We performed a cross-sectional analysis of all outpatient screening and surveillance colonoscopies among adults age 50 to 75 reported in the GI Quality Improvement Consortium (GIQuIC) from 2011 to 2018. The primary outcome was a recommendation to repeat colonoscopy within 1 year. Secondary outcomes included recommendations based on indication of colonoscopy and colonoscopy findings, and predictors of a recommendation to follow-up within 1 year.

There were 260,314 colonoscopies with inadequate bowel preparation performed at 672 different sites by 4,001 endoscopists. Of these, 31.9% contained a recommendation for follow-up within 1 year. This did not differ meaningfully by examination indication. The severity of colonoscopy findings influenced the recommendations for follow-up (within 1 year in 84.0% of cases with adenocarcinoma, 51.8% with any advanced lesion, and 23.2% with 1-2 small adenomas). Younger age, more severe pathology, location in the Northeast, and performance by an endoscopist with an adenoma detection rate ≥25% were associated with recommendations for follow-up within 1 year.

A minority of colonoscopies with inadequate bowel preparation are recommended to be repeated within 1 year, which may have implications for potential missed lesions. Further understanding of reasons driving recommendations is an important next step to improving guideline-concordant colonoscopy practice.

Mental health conditions during delivery hospitalizations are not well characterized.

This study aimed to characterize the prevalence of maternal mental health condition diagnoses and associated risk during delivery hospitalizations in the United States.

The 2000 to 2018 National Inpatient Sample was used for this repeated cross-sectional analysis. Delivery hospitalizations of women aged 15 to 54 years with and without mental health condition diagnoses, including depressive disorder, anxiety disorder, bipolar spectrum disorder, and schizophrenia spectrum disorder, were identified. Temporal trends in mental health condition diagnoses during delivery hospitalizations were determined using the National Cancer Institute's Joinpoint Regression Program to estimate the average annual percent change with 95% confidence intervals. The trends in chronic conditions associated with mental health condition diagnoses, including asthma, pregestational diabetes mellitus, chronic hypertension, obesity, and substance use condition diagnoses increased significantly throughout the study period. Mental health condition diagnoses were associated with other underlying chronic health conditions and a modestly increased risk of a range of adverse outcomes. The findings suggested that mental health conditions are an important risk factor in adverse maternal outcomes.
Opportunistic bilateral salpingo-oophorectomy (BSO) is often offered to patients undergoing benign hysterectomy to prevent ovarian cancer, but the magnitude of risk reduction obtained with BSO in this population remains unclear, and must be weighed against potential risks of ovarian hormone deficiency.

To quantify the relative and absolute risk reduction in ovarian cancer incidence and death associated with BSO at the time of benign hysterectomy.

We performed a population-based cohort study of all adult women (>20 years) undergoing benign hysterectomy from 1996 to 2010 in Ontario, Canada. Patients with ovarian pathology, prior breast/gynecologic cancer, or evidence of genetic susceptibility to malignancy were excluded. Inverse probability of treatment weighted Fine & Gray subdistribution hazard models were used to quantify the effect of BSO on ovarian cancer incidence and death, while accounting for competing risks and adjusting for demographic characteristics, gynecologic conditions, and comorbi hysterectomy. Population-average risk estimates derived in this study should be balanced against other potential implications of BSO in order to inform practice guidelines, patient decision-making, and surgical management.
BSO results in a significant absolute reduction in ovarian cancer among women undergoing benign hysterectomy. Population-average risk estimates derived in this study should be balanced against other potential implications of BSO in order to inform practice guidelines, patient decision-making, and surgical management.Food selectivity has been shown to be more persistent and severe in children with Tourette syndrome (TS) compared to their typically developing peers. The current study aimed to examine differences in food selectivity, food neophobia and Avoidant Restrictive Food Intake Disorder (ARFID)-associated behaviours, between adults with and without TS. Fifty-three adults diagnosed with TS were compared to 53 neurotypical adults and completed the following measures online Adult Eating Behaviour Questionnaire (AEBQ), Nine-Item Avoidant/Restrictive Food Intake disorder screen (NIAS), Food Neophobia Scale (FNS) and the Sensory Perception Quotient (SPQ). Higher levels of food avoidant behaviours, in terms of food fussiness, food neophobia and ARFID-associated behaviours, were identified in adults with TS compared to adults without TS. While heightened sensory sensitivity failed to predict food fussiness, greater sensitivity to taste was found to be predictive of food neophobia in TS. These are the first findings to suggest that food avoidant behaviours are more prevalent for adults with TS and signal a need to address health implications.Bromodomains are a group of structurally diverse proteins characterized as readers of post-translational modifications. They bear unique structural topology and are known to have diverse cellular functions. As epigenetic readers of histone acetylation, bromodomains appear to have both physiological and pathological implications. Among the various types of bromodomain-containing proteins, BRD2 and BRD4 proteins are expressed ubiquitously and act as critical regulators of the cell cycle in normal mammalian cells. Therefore, they are increasingly involved in the process of oncogenesis. Bromodomains are the emerging novel epigenetic targets for the treatment of cancer. Various small molecules are proposed to target the bromodomain proteins as the readers of acetyl-lysine residues. In recent years, inhibiting the interaction of acetyl-lysine residues and bromodomain proteins on chromatin has served as an interesting target to regulate the expression of various pathological genes, including BCL-2, MYC, and NF-κB. The review summarizes bromodomains as potential targets in cancer and various bromodomain inhibitors in the early stages of the clinical trial.
