An Unexpected Discovery: Postmenopausal Pyloric Endometriosis.

Endometriosis is a benign, estrogen-dependent condition, usually occurring in menstruating and, rarely, in postmenopausal women, in which endometrial glands and stroma grow ectopically outside the uterus. Most often, ectopic endometrial tissue is found within the pelvis and nearby structures. However, endometrial tissue within the upper gastrointestinal tract is very rare and can be a source of bleeding and abdominal pain. Here, we report a case of a 71-year-old postmenopausal woman with hematochezia and diffuse abdominal pain, who was found to have pyloric endometriosis, the pathogenesis of which we will briefly explore.

Representation of Racial Minorities in the United States Colonoscopy Surveillance Interval Guidelines.

BACKGROUND/AIMS: Clinical guidelines should ideally be formulated from data representative of the population they are applicable to; however, historically, studies have disproportionally enrolled non-Hispanic White (NHW) patients, leading to potential inequities in care for minority groups. Our study aims to evaluate the extent to which racial minorities were represented in the United States Colorectal Cancer Surveillance Guidelines. METHODS: We reviewed US guidelines between 1997 and 2020 and all identified studies cited by recommendations for surveillance after a baseline colonoscopy with no polyps, adenomas, sessile serrated polyps, and hyperplastic polyps. We analyzed the proportion of studies reporting race, and among these studies, we calculated the racial distribution of patients and compared the proportion of Non-NHW patients between each subtype. RESULTS: For all guidelines, we reviewed 75 studies encompassing 9,309,955 patients. Race was reported in 24% of studies and 14% of total patients. Non-NHW comprised 43% of patients in studies for normal colonoscopies, compared with 9% for adenomas, 22% for sessile serrated polyps, and 15% for hyperplastic polyps. For the 2020 guidelines, we reviewed 33 studies encompassing 5,930,722 patients. Race was reported in 15% of studies and 21% of total patients. Non-NHW comprised 43% of patients in studies for normal colonoscopies, compared with 9% for tubular adenomas. Race was not cited for any other 2020 guideline. CONCLUSION: Racial minorities are significantly underrepresented in US Colorectal Cancer Surveillance Guidelines, which may contribute to disparities in care. Future studies should prioritize enrolling a diverse patient population to provide data that accurately reflects their population.

Text recycling: Self-plagiarism in scientific writing.

To further the progress of scientific research and expand the literature, authors and editors share a common goal of producing and reviewing innovative publications. However, as publication rates increase, so does the amount of detected plagiarism, including self-plagiarism. This concept, also referred to as text recycling, is defined as the repurposing of one's own previously published work in new publications without referencing the original source. There are advocates both for and against versions of text recycling, but without a universal protocol for authors and editors of what constitutes self-plagiarism, there is no strict standard among journals as to what is unethical. The advent of online text duplication detection software has been increasingly used by journals to assure that all published work is novel, but challenges remain. Converging on standardized guidelines would be beneficial with regard to text recycling and improving author education and the promotion of active communication between journals and authors during the submission process if confusion arises.

Benign oral mucosal lesions: Clinical and pathological findings.

A diverse spectrum of benign oral mucosal lesions exists, presenting as either isolated oral findings or in association with dermatologic conditions. Oral lesions can closely resemble one another; therefore, it is important for clinicians to be able to recognize their distinctive features, to be able to recognize benign versus malignant disease, and to recognize when obtaining a biopsy specimen is warranted. The first article in this continuing medical education series reviews oral anatomy, the clinical attributes of several benign lesions of the oral cavity, and appropriate management and therapeutic modalities.

Premalignant and malignant oral mucosal lesions: Clinical and pathological findings.

The second article in this continuing medical education series discusses the clinical and histopathologic features of common premalignant and malignant lesions of the oral cavity. It is imperative for dermatologists to be able to appropriately recognize suspicious lesions, determine the need to obtain a biopsy specimen, counsel, and refer patients presenting with premalignant or malignant conditions. Given the higher rates of mortality and morbidity of oral mucosal malignancies because of late diagnosis, appropriate treatment with multidisciplinary care in a timely manner is essential to patients with these neoplasms.

Cardiometabolic profiles of adolescents and young adults exposed to the World Trade Center Disaster.

BACKGROUND AND OBJECTIVE: Few studies have examined the possible cardiometabolic consequences of World Trade Center-related exposures on children who lived and/or attended school near the disaster site. Our objective was to compare cardiometabolic profiles of participants in the World Trade Center Health Registry (WTCHR) with a matched comparison group. METHODS: We evaluated WTCHR enrollees who resided in New York City and were born between September 11, 1993 and September 10, 2001, and a matched comparison group. We assessed exposure to dust cloud, home dust, as well as traumatic exposure, and associations with blood pressure, arterial wall stiffness, body mass index (BMI), total cholesterol, triglycerides, HDL, and LDL. RESULTS: A total of 402 participants completed the study, 222 in the comparison group and 180 in the WTCHR group. In multivariable regression analysis, after adjusting for relevant confounders we detected a weak association between participation in the WTCHR group and lower BMI (-1.12kg/m2, 95% CI -2.11, -0.12; p = 0.03), which became non-significant after adjusting for multiple comparisons. With respect to traumatic and psychosocial exposures, the only association that persisted in our multivariable model, below our predefined level of significance, was between post-traumatic stress disorder and higher BMI (2.06kg/m2, 95% CI 0.37, 3.74; p = 0.02). CONCLUSIONS: Our findings do not support an association between self-reported exposures to the WTC disaster and adverse cardiometabolic profile. However, further longitudinal studies may better inform the full extent of WTC-related conditions associated with exposure to the disaster.

Serum perfluoroalkyl substances and cardiometabolic consequences in adolescents exposed to the World Trade Center disaster and a matched comparison group.

BACKGROUND: Large amounts of various chemical contaminants, including perfluoroalkyl substances (PFASs), were released at the time of the World Trade Center (WTC) disaster. Thousands of children who lived and/or attended school near the disaster site were exposed to these substances but few studies have examined the possible consequences related to these exposures. OBJECTIVES: To examine the relationship of PFASs serum levels with cardiometabolic profile in children and adolescents enrolled in the World Trade Center Health Registry (WTCHR) and a matched comparison group. METHODS: We evaluated WTCHR enrollees who resided in New York City and were born between September 11, 1993 and September 10, 2001, and a matched comparison group consisting of individuals who were ineligible for WTCHR participation upon distance of their home, school or work from the WTC and lack of participation in rescue and recovery activities. Matching was based on date of birth, sex, race, ethnicity, and income. We assessed exposure to PFASs, as measured by serum levels and association with cardiometabolic profile as measured by arterial wall stiffness, body mass index, insulin resistance, fasting total cholesterol, HDL, LDL and triglycerides. RESULTS: A total of 402 participants completed the study and serum samples were analyzed from 308 participants, 123 in the WTCHR group and 185 in the comparison group. In multivariable regression analysis, after adjusting for relevant confounders, we observed a significant, positive association of perfluorooctanoic acid (PFOA) with triglycerides (beta coefficient=0.14, 95% CI: 0.02, 0.27, 15.1% change), total cholesterol (beta coefficient=0.09, 95% CI: 0.04, 0.14, 9.2% change), and LDL cholesterol (beta coefficient=0.11, 95% CI: 0.03, 0.19, 11.5% change). Perfluorohexanesulfonic acid levels were associated with decreased insulin resistance (beta coefficient=-0.09, 95% CI: -0.18, -0.003, -8.6% change); PFOA and perfluorononanoic acid were associated with increased brachial artery distensibility. CONCLUSIONS: This research adds to our knowledge of the physical health impacts in a large group of children exposed to the WTC disaster. Abnormal lipid levels in young adults might be an early marker of atherosclerosis and cardiovascular diseases and our findings highlight the importance of conducting longitudinal studies in this population.

Reported maladaptive decision-making in unipolar and bipolar depression and its change with treatment.

Mood disorder patients frequently experience difficulty making decisions and may make sub-optimal decisions with adverse life consequences. However, patients' styles for decision-making when ill and after treatment have received little study to date. We assessed healthy controls (HC, n = 69) and patients with major depressive disorder (MDD, n = 61) or bipolar disorder (BP, n = 26) in a current major depressive episode using the Melbourne Decision-making Questionnaire. A subset of participants was re-evaluated after completing six weeks of pharmacotherapy. HC demonstrated significantly greater use of the healthy vigilance style, and significantly lower use of maladaptive decision-making styles, than the MDD and depressed BP patients. After six weeks of treatment, neither the MDD nor BP patients reported meaningful improvements in the vigilance style of decision-making, but scores on most maladaptive decision-making styles declined. BP patients who remitted reported significantly lower buckpassing and procrastination scores than healthy controls. Among MDD patients, however, the maladaptive passive buckpassing style of decision-making did not significantly diminish. For MDD patients, reported decision-making styles may remain impaired even after achieving remission. Among BP patients, low levels of adaptive vigilance decision-making may be a trait component of the illness, whereas for MDD patients, reported maladaptive passive decision-making styles are persistent.

Serum perfluoroalkyl substances in children exposed to the world trade center disaster.

The World Trade Center (WTC) disaster released large amounts of various chemical substances into the environment, including perfluoroalkyl substances (PFASs). Yet, no studies have examined exposures in children living or attending schools near the disaster site. We measured serum PFASs in WTC Health Registry (WTCHR) respondents who were ≤8 years of age on September 11, 2001 and a sociodemographically-matched comparison group. We also examined the relationship of PFASs levels with dust cloud exposure; home dust exposure, and with traumatic exposure, the latter to take into account differences related to possible mental health consequences and associated behavioral problems. Serum samples, collected between 2014 and 2016, were analyzed from 123 WTCHR participants and from 185 participants in the comparison group. In the WTCHR group, median perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) levels were 1.81ng/mL and 3.72ng/mL, respectively. Controlling for sex, caloric intake, race/ethnicity, and date of birth, significant increases among WTCHR participants compared with the matched comparison group were detected for perfluorohexanesulfonate (0.23ng/mL increase or 0.24log unit increase, p=0.006); PFOS (0.86ng/mL increase or 0.16log unit increase, p=0.011); PFOA (0.35ng/mL increase or 0.18log unit increase, p<0.001); perfluorononanoic acid (0.12ng/mL increase or 0.17log unit increase, p=0.003); perfluorodecanoic acid (0.06ng/mL increase or 0.42log unit increase, p<0.001); and perfluoroundecanoic acid (0.03ng/mL increase or 0.32log unit increase, p=0.019). Stronger associations were identified for home dust exposures and traumatic exposures than dust cloud. These findings highlight the importance of conducting longitudinal studies in this population to assess possible cardiometabolic and renal consequences related to these exposures.
