Discontinuing semaglutide after weight loss: strategy for weight maintenance and a possible new side effect.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) facilitate weight loss. Weight regain off therapy is concerning. We reported the case of a 35-year-old male prescribed oral semaglutide with 22.7 kg weight loss over 120 days. Herein, we describe the clinical course when discontinuing GLP-1 RA therapy, one approach to maintaining weight loss after discontinuation, and a possible new side effect. At day 120, we continued oral semaglutide 7 mg daily, down from 14 mg, for weight maintenance with subsequent weight regain. We re-increased semaglutide to 14 mg/day with weight re-loss within 1 month and weight maintance for a year. We then discontinued semaglutide; weight loss was maintained for 6 months. The patient reported lactose intolerance ∼13 months before starting semaglutide. During semaglutide therapy, the patient reported worsened lactose intolerance and new gluten intolerance. Food allergy/celiac testing were negative. Intolerances did not improve with semaglutide discontinuation. Six months after semaglutide discontinuation, the patient was diagnosed with small intestinal bacterial overgrowth, possibly worsened by semaglutide. Factors potentially supporting weight maintenance were early drug treatment for new-onset obesity, non-geriatric age, strength training, and diet modification. The case highlights tailoring approaches to maintain weight loss without GLP-1 RAs. Trials are needed to optimize weight maintenance strategies.

Preoperative comorbidities as a predictor of EBWL after bariatric surgery: a retrospective cohort study.

INTRODUCTION: The purpose of this study is to investigate the impact of preoperative comorbidities, including depression, anxiety, type 2 diabetes mellitus, obstructive sleep apnea, hypothyroidism, and the type of surgery on %EBWL (percent estimated body weight loss) in patients 1 year after bariatric surgery. Patients who choose to undergo bariatric surgery often have other comorbidities that can affect both the outcomes of their procedures and the postoperative period. We predict that patients who have depression, anxiety, diabetes mellitus, obstructive sleep apnea, or hypothyroidism will have a smaller change in %EBWL when compared to patients without any of these comorbidities. METHODS AND PROCEDURES: Data points were retrospectively collected from the charts of 440 patients from March 2012-December 2019 who underwent a sleeve gastrectomy or gastric bypass surgery. Data collected included patient demographics, select comorbidities, including diabetes mellitus, obstructive sleep apnea, hypothyroidism, depression, and anxiety, and body weight at baseline and 1 year postoperatively. Ideal body weight was calculated using the formula 50 + (2.3 × height in inches over 5 feet) for males and 45.5 + (2.3 × height in inches over 5 feet) for females. Excess body weight was then calculated by subtracting ideal body weight from actual weight at the above forementioned time points. Finally, %EBWL was calculated using the formula (change in weight over 1 year/excess weight) × 100. RESULTS: Patients who had a higher baseline BMI (p < 0.001), diabetes mellitus (p = 0.026), hypothyroidism (p = 0.046), and who had a laparoscopic sleeve gastrectomy rather than Roux-en-Y gastric bypass (p < 0.001) had a smaller %EBWL in the first year after bariatric surgery as compared to patients without these comorbidities at the time of surgery. Controversially, patients with anxiety or depression (p = 0.73) or obstructive sleep apnea (p = 0.075) did not have a statistically significant difference in %EBWL. CONCLUSION: A higher baseline BMI, diabetes mellitus, hypothyroidism, and undergoing laparoscopic sleeve gastrectomy may lead to lower %EBWL in the postoperative period after bariatric surgery. At the same time, patients' mental health status and sleep apnea status were not related to %EBWL. This study provides new insight into which comorbidities may need tighter control in order to optimize weight loss outcomes after bariatric surgery.

Endoscopic closure techniques of bariatric surgery complications: a meta-analysis.

BACKGROUND: Leaks following bariatric surgery, while rare, are potentially fatal due to risk of peritonitis and sepsis. Anastomotic leaks and gastro-gastric fistulae following Roux-En-Y gastric bypass (RYGB) as well as staple line leaks after sleeve gastrectomy have historically been treated multimodally with surgical drainage, aggressive antibiotic therapy, and more recently, endoscopically. Endoscopic clipping using over-the-scope clips and endoscopic suturing are two of the most common approaches used to achieve full thickness closure. METHODS: A systematic literature search was performed in PubMed to identify articles on the use of endoscopic clipping or suturing for the treatment of leaks and fistulae following bariatric surgery. Studies focusing on stents, and those that incorporated multiple closure techniques simultaneously, were excluded. Literature review and meta-analysis were performed with the PRISMA guidelines. RESULTS: Five studies with 61 patients that underwent over-the-scope clip (OTSC) closure were included. The pooled proportion of successful closure across the studies was 81.1% (95% CI 67.3 to 91.7). The successful closure rates were homogeneous (I2 = 39%, p = 0.15). Three studies with 92 patients that underwent endoscopic suturing were included. The weighted pooled proportion of successful closure across the studies was shown to be 22.4% (95% CI 14.6 to 31.3). The successful closure rates were homogeneous (I2 = 0%, p = 0.44). Three of the studies, totaling 34 patients, examining OTSC deployment reported data for reintervention rate. The weighted pooled proportion of reintervention across the studies was 35.0% (95% CI 11.7 to 64.7). We noticed statistically significant heterogeneity (I2 = 68%, p = 0.04). One study, with 20 patients examining endoscopic suturing, reported rate of repeat intervention 60%. CONCLUSION: Observational reports show that patients managed with OTSC were more likely to experience healing of their defect than those managed with endoscopic suturing. Larger controlled studies comparing different closure devices for bariatric leaks should be carried out to better understand the ideal endoscopic approach to these complications.

Robotics vs Laparoscopy in Foregut Surgery: Systematic Review and Meta-Analysis Analyzing Hiatal Hernia Repair and Heller Myotomy.

BACKGROUND: Laparoscopic surgery remains the mainstay of treating foregut pathologies. Several studies have shown improved outcomes with the robotic approach. A systematic review and meta-analysis comparing outcomes of robotic and laparoscopic hiatal hernia repairs (HHR) and Heller myotomy (HM) repairs is needed. STUDY DESIGN: PubMed, Embase and Scopus databases were searched for studies published between January 2010 and November 2022. The risk of bias was assessed using the Cochrane ROBINS-I tool. Assessed outcomes included intra- and post-operative outcomes. We pooled the dichotomous data using the Mantel-Haenszel random effects model to report odds ratio (OR) and 95% confidence intervals (95% CIs) and continuous data to report mean difference (MD) and 95% CIs. RESULTS: Twenty-two comparative studies enrolling 196,339 patients were included. Thirteen (13,426 robotic, 168,335 laparoscopic patients) studies assessed HHR outcomes, while nine (2,384 robotic, 12,225 laparoscopic patients) assessed HM outcomes. Robotic HHR had a non-significantly shorter length of hospital stay (LOS) [MD -0.41 (95% CI -0.87, -0.05)], fewer conversions to open [OR 0.22 (95% CI 0.03, 1.49)], and lower morbidity rates [OR 0.76 (95% CI 0.47, 1.23)]. Robotic HM led to significantly fewer esophageal perforations [OR 0.36 (95% CI 0.15, 0.83)], reinterventions [OR 0.18 (95% CI 0.07, 0.47)] a non-significantly shorter LOS [MD -0.31 (95% CI -0.62, 0.00)]. Both robotic HM and HHR had significantly longer operative times. CONCLUSIONS: Laparoscopic and robotic HHR and HM repairs have similar safety profiles and perioperative outcomes. Randomized controlled trials are warranted to compare the two methods, given the low to moderate quality of included studies.

Association of Common Foods with Inflammation and Mortality: Analysis from a Large Prospective Cohort Study.

Some dietary patterns are associated with inflammation, while others lower inflammation and improve health. However, many people cannot follow a complete, healthy diet. Therefore, this study's aim was to identify specific foods associated chronic inflammation and mortality. The study used Multi-Ethnic Study of Atherosclerosis (MESA) research materials from the NHLBI Biologic Specimen and Data Repository Information Coordinating Center. Three plant-based and three animal-based MESA food categories were chosen based on perceived availability in the western diet. The assessed food categories were avocado, ham, sausage, eggs, greens, and broccoli. Inflammatory markers assessed were interleukin-6 (IL-6), fibrinogen antigen, C-reactive protein, D-Dimer, interleukin-2, matrix metalloproteinase 3, necrosis factor-a soluble receptors, oxidized LDL (oxLDL), and total homocysteine. The primary outcome was the multivariable association of foods and inflammatory markers with all-cause mortality. All inflammatory makers, except oxLDL, were associated with mortality in univariate analysis. The effect was largest with IL-6 and D-dimer. The category of broccoli had the most consistent association in univariate analyses with lower inflammation and lower mortality odds. Low and high broccoli consumption versus no consumption were associated with lower mortality odds in the multivariable models with IL-6 and D-dimer. Consumption of the MESA-defined food category "broccoli" (i.e., broccoli, cabbage, cauliflower, brussels sprouts, sauerkraut, and kimchee) was associated with lower inflammation and lower mortality odds. These findings should be validated in randomized controlled trials testing a "food is medicine" approach to identify which, if any, of these foods may have potential as an herbal therapeutic for chronic inflammation.

Minding the gap: towards a shared clinical reasoning lexicon across the pre-clerkship/clerkship transition.

Teaching and learning of clinical reasoning are core principles of medical education. However, little guidance exists for faculty leaders to navigate curricular transitions between pre-clerkship and clerkship curricular phases. This study compares how educational leaders in these two phases understand clinical reasoning instruction. Previously reported cross-sectional surveys of pre-clerkship clinical skills course directors, and clerkship leaders were compared. Comparisons focused on perceived importance of a number of core clinical reasoning concepts, barriers to clinical reasoning instruction, level of familiarity across the undergraduate medical curriculum, and inclusion of clinical reasoning instruction in each area of the curriculum. Analyses were performed using the Mann Whitney U test. Both sets of leaders rated lack of curricular time as the largest barrier to teaching clinical reasoning. Clerkship leaders also noted a lack of faculty with skills to teach clinical reasoning concepts as a significant barrier (p < 0.02), while pre-clerkship leaders were more likely to perceive that these concepts were too advanced for their students (p < 0.001). Pre-clerkship leaders reported a higher level of familiarity with the clerkship curriculum than clerkship leaders reported of the pre-clerkship curriculum (p < 0.001). As faculty transition students from the pre-clerkship to the clerkship phase, a shared understanding of what is taught and when, accompanied by successful faculty development, may aid the development of longitudinal, milestone-based clinical reasoning instruction.

The emergence of MedTok: a qualitative analysis of popular medical TikTok videos.

Social media is increasingly being used by the public as a medium for health information. Unfortunately, misinformation has become widely available on these sites, often being provided using content that is designed to be more popular and engaging, and it is difficult for the public to differentiate between what is true and what is false. TikTok is one of these platforms and has been rapidly growing over the last few years. As an increasing number of people look to TikTok for their health information, it is important that quality information is accessible and popular on the platform. We conducted a review of TikTok videos using the top 10 videos to show when searching for 13 common conditions. Characteristics of both the creator and video were recorded and analyzed. Videos on conditions commonly diagnosed younger were commonly produced by younger creators with the condition, often based on their own experiences. Conversely, videos on conditions commonly diagnosed older were commonly produced by healthcare professionals providing educational information. Though for conditions affecting older individuals healthcare professionals may be able to create didactic, educational videos, for those affecting younger individuals, it may be beneficial to partner with younger creators, or "influencers," to produce more viral content. Further studies may expand on these ideas to encompass more facets of healthcare. As this study did not analyze the quality of the information in the videos, future research should also focus on determining the quality of popular content on TikTok and other social media platforms.

Significant tumor compression of the middle cerebellar peduncle is associated with worse facial nerve outcomes and lower extent of resection in surgery for medium-sized vestibular schwannomas - A radiographic analysis of a case series.

BACKGROUND AND OBJECTIVE: Optimizing the extent of resection (EOR) and facial nerve outcomes (FNO) remain a challenge in medium to large vestibular schwannomas (VS). Currently, tumor size has been the only consistently reported factor predicting FNO and EOR. Here, we sought to evaluate whether the degree of the tumor's compression on the middle cerebellar peduncle (PC) influences FNO and EOR in medium to large VS. METHODS: This retrospective case series included 99 patients who underwent surgical resection of their VSs from 2014 to 2022. Preoperative MR imaging was used to measure the degree of PC. Patient medical records were queried to determine the EOR and FNO. RESULTS: Patients with unfavorable FNO (HB 3 +) immediately post-op had significantly greater PC than those with favorable FNO (19.9 vs. 15.4 mm, P = .047). This significance was not observed at the last follow-up but there was a trend. When medium-sized tumors (15-30 mm) were analyzed separately, patients with unfavorable FNO immediate post-op and at last follow-up had significantly greater PC than their favorable counterparts (14.1 vs 8.7 mm). Significantly greater PC was also observed in patients who underwent subtotal resection (20.7 mm) compared to near (14.3 mm) and gross total resection (10.8 mm). Multivariate analyses confirmed these findings in medium-sized tumors, but not large-sized tumors. CONCLUSION: The degree of PC as measured on preoperative imaging can predict FNO and EOR in medium-sized vestibular schwannomas. Medium-sized tumors with > 15 mm of PC likely will have worse FNO and lower EOR.

Pelvic Incidence as a Predictor of Proximal Junctional Failure in Patients Undergoing Anterior Column Realignment with Anterior Longitudinal Ligament Release to Restore Lordosis in Adult Spinal Deformity: A Retrospective Cohort Study.

OBJECTIVE: To identify variables that may contribute to the development of proximal junctional failure (PJF) in patients with long lumbo-sacral and thoraco-lumbo-pelvic constructs undergoing anterior column realignment (ACR) with anterior longitudinal ligament release (ALLR). METHODS: Data of patients with adult spinal deformity who underwent ACR with ALLR at L3-4 were collected retrospectively from medical records and a prospectively maintained spine research database between 2016 and 2022. RESULTS: Eleven (41%) developed PJF at a mean of 24 ± 21 months from the index surgery. The cohort was then divided into 2 groups for analysis, 13 subjects in the high pelvic incidence (PI) group (defined as PI ≥ 55°) and 14 subjects in the low PI group (defined as PI < 55°). Visual Analog Scale for back pain and Oswestry Disability Index decreased from 9.5 to 2.1 and 61 to 10 in the high PI group, and from 8.9 to 2.4 and 60.9 to 10.3 in the low PI group, respectively. PI (P = 0.004), sacral slope (P = 0.005), and postoperative PI-lumbar lordosis mismatch (P = 0.02) were found to be significant predictors of PJF. The receiver operator curve revealed a cutoff PI value ≤ 53° (95% confidence interval: 52°-64°), below which the risk of PJF becomes significantly higher in patients undergoing ACR with ALLR at L3-4. CONCLUSIONS: PI may be a predictor of PJF and highly correlates with ACR-ALLR levels. In patients undergoing L3-4 ACR-ALLR, a PI value of ≤53° is associated with a significantly elevated risk of PJF. Preoperative planning of ACR-ALLR level based on normal sagittal alignment in otherwise healthy individuals may mitigate the risk of PJF development in patients with adult spinal deformity treated with ACR-ALLR.

Hernia repair in the bariatric patient: a systematic review and meta-analysis.

BACKGROUND: Repair options for ventral hernias in bariatric patients include performing a staged approach in which bariatric surgery is performed before definitive hernia repair (BS-first), a staged approach in which hernia repair is performed before bariatric surgery (HR-first), or a concomitant approach. OBJECTIVES: This meta-analysis aims to determine which surgical approach is best for bariatric patients with hernias. SETTING: PubMed, CENTRAL, and Embase databases. METHODS: A comprehensive search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to screen for all studies that focused on outcomes of patients who underwent both hernia repair and bariatric surgery, either simultaneously or separately. Exclusion criteria included hiatal and inguinal hernia studies, case reports, and case series. RESULTS: 27 studies fit our inclusion criteria after identifying 1584 studies initially. Seven comparative studies were included, enrolling 8548 staged patients (6458 BS-first) and 3528 concomitant patients. A total of 7 single-arm staged studies and 13 single-arm concomitant studies were also included. Data on hernia recurrence, mesh infection, reoperation, surgical site infections, seroma, bowel complications, and mortality were abstracted. The concomitant approach was associated with decreased odds of experiencing surgical site infections, reoperation, and seromas. The staged approach (BS-first) was associated with decreased odds of mesh infection. The single-arm studies suggest a lower incidence of hernia recurrence in a staged BS-first approach than in a concomitant approach. CONCLUSIONS: The data suggest a concomitant approach is appropriate for hernias that the surgeon feels do not require mesh, while the staged (BS-first) approach is more appropriate if the hernia requires mesh placement.

Breastfeeding Ability After Breast Reductions: What does the Literature Tell us in 2023?

INTRODUCTION: Reduction mammaplasties are routinely performed on women of child-bearing age, yet there still exists some uncertainty regarding a patient's ability to breastfeed following the procedure. This is due to inconsistent definitions of "successful" breastfeeding, a variety of pedicles implemented, and inadequate follow-up in the published literature. Our aim was to summarize the current data and provide clear recommendations for counseling patients on expected breastfeeding outcomes following reduction mammaplasty. METHODS: A systematic review and meta-analysis in accordance with the PRISMA guidelines was conducted. We included papers that reported proportion of breastfeeding ability following reduction mammaplasty. RESULTS: We identified 33 papers that met our inclusion criteria. We found that women who undergo reduction mammaplasty are at a 3.5 times increased odds of not being able to breastfeed compared to controls. Overall, reduction mammaplasty patients have a breastfeeding success rate of 62%. The breastfeeding success rate for patients with inferior pedicles was 64%, superior pedicles was 59%, and lateral pedicles was 55%. No conclusions could be drawn regarding medial, central, vertical, and horizontal pedicles on breastfeeding ability. CONCLUSION: Current data suggest that women undergoing reduction mammaplasty have an increased odds of unsuccessful breastfeeding when compared to similar women who have not undergone the procedure. Based on the current literature, pedicle type does play a role in rate of breastfeeding success, although there is a need for further research on the aforementioned pedicles. Physicians should be aware of the likelihood of successful breastfeeding following reduction mammaplasty so that patients can be more thoroughly counseled prior to a decision for surgery.

Reliability of Electronic Health Records in Recording Veterans' Tobacco Use Status.

INTRODUCTION: The prevalence of tobacco use in the Veteran population and among Veterans Health Administration patients remains high, resulting in significant health and economic consequences. This problem has generated many tobacco research studies and clinical interventions, which often rely upon tobacco use status data previously recorded in electronic health records (EHR). Therefore, the consistency and reliability of these data are critical. The Veterans Health Administration uses an extensive EHR system where tobacco use status can be documented either as free text (FT) or as health factors (HF). The current literature assessing the reliability of HF and FT data is limited. This analysis evaluated the agreement between HF and FT tobacco use status data. MATERIALS AND METHODS: This retrospective study included Veterans who underwent coronary revascularization and had tobacco use statuses recorded as both HF and FT. These statuses were categorized as "Current," "Former," or "Never." The closest recorded status to the index date (date of revascularization procedure) for each subject in both datasets was chosen, and Cohen's kappa statistic was calculated to measure the agreement between HF and FT. Implausible tobacco use status changes within each dataset were quantified to assess trustworthiness. Agreement between HF and FT data was first measured for all subjects (n = 1,095), which included those who had implausible status changes in either dataset and then measured again for subjects (n = 770) without any implausible status changes in either dataset. This study was exempt from institutional review board review. RESULTS: Overall, 14.3% and 17.7% of all subjects had implausible tobacco use status changes in HF and FT data, respectively. For all subjects (n = 1,095), including those with implausible data, there was "moderate" agreement between HF and FT data (kappa = 0.49; 95% CI, 0.44-0.53). For subjects without implausible data (n = 770), the strength of agreement between HF and FT data was "good" (kappa = 0.64; 95% CI, 0.59-0.69). CONCLUSIONS: Agreement between HF and FT data that document the tobacco use statuses of Veterans varied because of implausible data. HF data had fewer implausible tobacco use statuses, but FT data were recorded more frequently. Although HF and FT data can be reasonably relied upon to determine the tobacco use statuses of Veterans, researchers and clinicians must be aware of implausible data and consider methods to overcome this limitation. Future studies should investigate the ways of improving the consistency of EHR documentation by health care providers and benchmark HF and FT data against a gold standard like biochemical verification to determine accuracy.

Safety and efficacy of anti-BCMA CAR-T cell therapy in older adults with multiple myeloma: A systematic review and meta-analysis.

INTRODUCTION: Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor T-cell (CAR-T) therapy is transforming the care of patients with relapsed/refractory multiple myeloma (MM). Unfortunately, despite being a disease of older adults these patients remain under-represented in most pivotal clinical trials. We performed a systematic review and proportion meta-analysis of prospective clinical trials and observational studies of anti-BCMA CAR-T therapy in patients with MM with the aim to determine the efficacy and safety of this therapy in older adults (≥65 years). MATERIALS AND METHODS: We searched the Pubmed, Scopus, Web of Science (WOS), Ovid, Embase, CENTRAL, and CINAHL databases through September 9, 2022 and abstracts from the American Society of Hematology (ASH) Annual Meeting 2022. Primary outcome measures included overall response rate (ORR), rates of cytokine release syndrome (CRS), and immune cell-effector-associated neurotoxicity syndrome (ICANS). study was registered with PROSPERO (study number: CRD42022334287). RESULTS: After screening 2218 references, 14 studies were included for data extraction, with a total of 558 patients, 26.2% (n = 146) of whom were older adults. The pooled ORR amongst this population was 93%, which was comparable to the ORR of 86% amongst younger patients. In older adults, the rates of CRS (any grade) and grade ≥ 3 were 95% and 21%, respectively. For younger patients, the pooled rate of CRS (any grade) and grade ≥ 3 CRS was 91% and 20%, respectively. The rate of ICANS (any grade) in older adults was 15%, which was higher than that observed in those <65 years. CONCLUSION: Older adults experience comparable outcomes to younger patients with anti-BCMA CAR-T therapy, albeit with numerically higher rates of neurotoxicity.

Predictors of endobronchial forceps utilization for inferior vena cava filter retrieval: when snare retrieval fails.

BACKGROUND: Endobronchial forceps are commonly used for complex IVC filter removal and after initial attempts at IVC filter retrieval with a snare have failed. Currently, there are no clear guidelines to help distinguish cases where primary removal should be attempted with standard snare technique or whether attempts at removal should directly be started with forceps. This study is aimed to identify clinical and imaging predictors of snare failure which necessitate conversion to endobronchial forceps. METHODS: Retrospective analysis of 543 patients who underwent IVC filter retrievals were performed at three large quaternary care centers from Jan 2015 to Jan 2022. Patient demographics and IVC filter characteristics on cross-sectional images (degree of tilt, hook embedment, and strut penetration, etc.) were reviewed. Binary multivariate logistic regression was used to identify predictors of IVC filter retrieval where snare retrieval would fail. RESULTS: Thirty seven percent of the patients (n = 203) necessitated utilization of endobronchial forceps. IVC filter hook embedment (OR:4.55; 95%CI: 1.74-11.87; p = 0.002) and strut penetration (OR: 56.46; 95% CI 20.2-157.7; p = 0.001) were predictors of snare failure. In contrast, total dwell time, BMI, and degree of filter tilt were not associated with snare failure. Intraprocedural conversion from snare to endobronchial forceps was significantly associated with increased contrast volume, radiation dose, and total procedure times (p < 0.05). CONCLUSION: IVC filter hook embedment and strut penetration were predictors of snare retrieval failure. Intraprocedural conversion from snare to endobronchial forceps increased contrast volume, radiation dose, and total procedure time. When either hook embedment or strut penetration is present on pre-procedural cross-sectional images, IVC filter retrieval should be initiated using endobronchial forceps. LEVEL OF EVIDENCE: Level 3, large multicenter retrospective cohort.

Poor Oral Health Linked with Higher Risk of Alzheimer's Disease.

Alzheimer's disease (AD) is a multifactorial neurodegenerative disease characterized by cognitive and behavioral changes in older adults. Emerging evidence suggests poor oral health is associated with AD, but there is a lack of large-scale clinical studies demonstrating this link. Herein, we used the TriNetX database to generate clinical cohorts and assess the risk of AD and survival among >30 million de-identified subjects with normal oral health (n = 31,418,814) and poor oral health (n = 1,232,751). There was a greater than two-fold increase in AD risk in the poor oral health cohort compared to the normal oral health group (risk ratio (RR): 2.363, (95% confidence interval: 2.326, 2.401)). To reduce potential bias, we performed retrospective propensity score matching for age, gender, and multiple laboratory measures. After matching, the cohorts had no significant differences in survival probability. Furthermore, when comparing multiple oral conditions, diseases related to tooth loss were the most significant risk factor for AD (RR: 3.186, (95% CI: 3.007, 3.376)). Our results suggest that oral health may be important in AD risk, regardless of age, gender, or laboratory measures. However, more large-scale cohort studies are necessary to validate these findings and further evaluate links between oral health and AD.

A Retrospective Cohort Study Assessing the Impact of Statin Therapy on Hospital Length of Stay and Inpatient Mortality in COVID-19 Patients.

Background: Coronaviruses, known for their crown-like appearance, cause mild gastrointestinal and respiratory diseases. Some cause outbreaks of respiratory diseases, most recently, SARS-CoV-2, the coronavirus disease 2019 (COVID-19). Individuals with COVID-19 are reported to be in both arterial and venous prothrombotic states. In addition to a lipid-lowering effect, statin also has an anti-inflammatory effect, which addresses one of the underlying causes of thrombosis. An in-silico study revealed that statins could directly interact with the main protease enzyme of SARS-CoV-2 and prevent infectivity. Due to these pleiotropic properties, statins may positively impact the outcome of hospitalized patients with COVID-19 infections. Methods: A total of 26 445 acute COVID-19-infected patients were included in this study. Patients were stratified based on home statin use status: no statins, high-intensity statins (atorvastatin 40-80 mg daily and rosuvastatin 20-40 mg daily), and low-to-moderate intensity statins (all other statins). A multivariate generalized linear model and logistic regression were used to predict the hospital length of stay and inpatient mortality, respectively. Results: The hospital length of stay was compared between low-intensity and high-intensity statin use against no statin therapy. The length of stay was 3.88 days (95% CI, 3.56-4.20; P < .0001) longer among patients with low-dose statin therapy compared to patients without. The length of stay was 4.77 days (95% CI, 4.42-5.13; P <.0001) longer among patients with high-intensity statin therapy than those without. The odds of in-hospital mortality decreased by 24% (OR, 0.76; 95% CI, 0.76-0.97) among those with high-dose statin therapy compared to patients without (P = .02). There was no statistical significance between the low-dose statin group and the no statin group for inpatient mortality. Conclusion: Hospitalized COVID-19 patients on statin therapy, regardless of intensity, are more likely to have a longer length of stay. There may be a mortality benefit in using high-intensity statin in acute COVID-19-infected patients. The results of this study are insufficient to recommend statin therapy for inpatient COVID-19 treatment. However, patients with significant cardiovascular comorbidities, where statins are indicated, should be on these medications, especially amidst the COVID-19 pandemic. Randomized controlled trials are needed to assess the potential in-hospital benefit of statin therapy on COVID-19 patients.

A meta-analysis and systematic review of endovascular thrombectomy versus medical management for acute basilar artery occlusion.

OBJECTIVE: Acute basilar artery occlusion (BAO) is a devastating neurologic event. As endovascular thrombectomy (EVT) became more prevalent for anterior circulation strokes, investigations were conducted in the posterior circulation. Its success in improving outcomes compared to standard medical therapy (SMT) after BAO has been debated. METHODS: We conducted a systematic review and meta-analysis of all randomized controlled trials (RCTs) and observational cohort studies evaluating EVT compared to SMT in acute BAO. We queried PubMed, Embase, and Cochrane for studies. Primary outcome was good functional outcome at 90 days (modified Rankin scale (mRS) ≤ 3). We analyzed studies for risk of bias (ROB) and calculated pooled risk ratios (RRs), odds ratios (ORs), and mean differences (MDs) with 95% confidence intervals (95%CI) using the random effects model for our primary outcome and secondary positive outcomes and harms. RESULTS: We identified four RCTs (991 patients randomized) and three cohort studies (1030 patients treated in-trial) that fit inclusion criteria. Three RCTs had low ROB, one had serious ROB. One cohort study had high ROB, one had moderate ROB, and one had low ROB. EVT was statistically significantly more associated with good functional outcome than SMT in RCTs (RR=1.54, 95%CI=1.16-2.04, p = 0.003) and trended towards significance in cohort studies (RR=2.64, 95%CI=0.87-8.00, p = 0.09). Mean mRS at 90 days was lower in EVT patients in RCTs (MD=-0.65, 95%CI=-1.07--0.22, p = 0.003) though not cohort studies (MD =-0.84, 95%CI=-2.48-0.79, p = 0.31). Symptomatic intracerebral hemorrhage (sICH) was statistically significantly associated with EVT in RCTs (OR=6.36, 95%CI=2.24-18.07, p < 0.001) and statistically non-significantly in cohort studies (OR=4.51, 95CI=1.00-20.33, p = 0.05). Mortality at 90 days was statistically lower with EVT than with SMT in both RCTs (OR=0.76, 95%CI=0.65-0.88, p < 0.001) cohort studies (OR=0.36, 95%CI=0.26-0.50, p < 0.001) CONCLUSION: EVT is associated with greater rates of good functional outcomes and lower rates of death and disability despite higher rates of periprocedural sICH.

Feasibility of Anti-reflux Gastric Bypass for Massive Paraesophageal Hernia in Obese Patients With Gastroesophageal Reflux Disease.

Background The objective of this study is to demonstrate the safety and feasibility of anti-reflux gastric bypass (ARGB) as a treatment for symptomatic massive paraesophageal hernias (PEH) in the obese population. Both gastroesophageal reflux disease (GERD) and PEH are particularly prevalent in the obese patient population, and obesity adversely affects the long-term outcomes of all anti-reflux procedures. Methods This is a single-center, retrospective review of 17 obese adults who underwent ARGB for the treatment of massive PEH between September 2019 and December 2021. Massive PEH was defined as >5 cm in a singular direction, and obesity as BMI ≥30 kg/m2. Patients without preoperative diagnostic testing were excluded. We reviewed and analyzed patient demographic data, postoperative symptom resolution, weight loss, and complications using descriptive statistics, change from baseline, and comparison of proportions. Results Sixteen of the 17 subjects were female. The median age was 48, and the median BMI was 39.10 kg/m2 (30.0-49.3 kg/m2). The average PEH size on imaging was 6.48 (H) x 6.25 (W) cm. The resolution of heartburn was 93.8% (p<0.001), and the resolution of nausea and vomiting was 80.0%. The mean postoperative length of follow-up was 9.12 months. Median excess body weight loss percentages at one, three, six, and 12 months were 16.43% (p<0.001), 35.92% (p<0.001), 40.64% (p=0.001), and 58.58% (p<0.01), respectively. Five patients experienced adverse events requiring additional intervention or hospitalization. There were no symptomatic hernia recurrences or mortality. Conclusion This study demonstrates that ARGB is feasible and potentially effective in treating symptomatic massive paraesophageal hernias in the obese patient population. Further investigation is needed to determine efficacy and long-term outcomes compared to standard surgical repair.
