Thousands of patients undergo major esophagectomy surgery in the United States each year, during which all or a portion of the esophagus is removed. A major complication of these surgeries is the occurrence of an irregular heartbeat known as atrial fibrillation (AF), which develops in up to 40% of patients undergoing these procedures. AF is characterized by rapid, irregular, chaotic beating of the two smaller chambers of the heart (the atria), leading to rapid, irregular beating of the two larger chambers (the ventricles). The average time to occurrence of post-surgical AF is 2-3 days following surgery. AF occurring following esophagectomy can result in extremely rapid heart rates, as fast as 150-200 beats per minute, and may be associated with serious consequences, including severely low blood pressure and potentially debilitating stroke. Further, the risk of death following esophagectomy is significantly higher in patients who develop AF compared with those who do not. Therefore, the occurrence of this irregular heartbeat following esophagectomy is associated with severe, potentially life-threatening consequences. Prevention of this irregular heartbeat in these patients may therefore be very important.

Amiodarone is a medication that is known to be effective for prevention and treatment of AF that occurs in patients who have not undergone surgery. In addition, amiodarone has been shown to be effective for prevention of AF following open-chest heart surgery. However, the use of medications for prevention of AF following esophagectomy has not been well studied, and amiodarone has not been studied in a controlled trial for the prevention of AF in this population. In addition, amiodarone is associated with side effects, and it is important to determine the safety of this medication when used in this patient population.
BACKGROUND: Indoleamine-2,3-dioxygenase (IDO) helps orchestrate immune suppression and checkpoint inhibitor resistance in hepatocellular carcinoma (HCC). BMS-986,205 is a novel oral drug that potently and selectively inhibits IDO. This Phase I/II study evaluated the safety and tolerability of BMS-986,205 in combination with nivolumab as first-line therapy in advanced HCC.
METHODS: Adults with untreated, unresectable/metastatic HCC received BMS-986,205 at two dose levels (50-100 mg orally daily) in combination with fixed dose nivolumab (240mg/m2 IV on Day 1 of each 14-day cycle). The primary objective was to determine the safety and tolerability of this combination; secondary objectives were to obtain preliminary efficacy.
RESULTS: Eight patients received a total of 91 treatment cycles in the dose escalation phase. All patients were Child Pugh A and 6 patients had underlying viral hepatitis. In the 6 evaluable patients, no dose-limiting toxicities (DLTs) were observed. The most common treatment-related adverse events (TRAEs) were aspartate transaminase (AST) and alanine transaminase (ALT) elevation (3 patients) and diarrhea, maculopapular rash and increased alkaline phosphatase (2 patients each). Grade 3 events were diarrhea and AST elevation (1 patient), and hyperglycemia and pancreatitis requiring treatment discontinuation (1 patient). No grade 4-5 events occurred. Partial response was observed in 1 patient (12.5%) and stable disease in 3 patients (37.5%), yielding a disease control rate of 50%. Median PFS was 8.5 weeks; median OS was not reached.
CONCLUSION: Combination BMS-986,205 and nivolumab showed a manageable safety profile with durable benefit as first-line therapy in a meaningful subset of advanced HCC patients.
Accurate placement of the double-lumen tube \[DLT\], the commonly used tool to provide one-lung ventilation during thoracic surgery, is a real challenge for the thoracic anesthesiologists. Optimal DLT depth, defined as the blue endobronchial cuff below the carina, would decrease the incidence of obstructing the trachea and the contralateral bronchus (Brodsky). Additionally, deep insertion of the bronchial cuff of the DLT would obstruct the upper lobe bronchus (Brodsky). The careful adjustment of the depth and optimal positioning of the DLT using a flexible fiberoptic bronchoscope need a skilled anesthesiologist to reduce the time to DLT intubation. (Charles D. Boucek et al)

There are several methods have been described to predict the proper depth of DLT insertion. Chow et al. documented the validity of the developed formula based on the clavicular-to-carinal distance of trachea and height in 78% of patients studied. Brodsky et al. demonstrated that a height-and-gender-based formula could predict the depth of DLT insertion. Liu et al. reported an accurate depth of DLT insertion in 90% of patients studied measuring the distance between the vocal cord and carina according to the chest CT.
BACKGROUND: Women show increased prevalence and severity of migraine compared to men. Whether small molecule calcitonin gene-related peptide receptor (CGRP-R) antagonists (i.e., gepants) and monoclonal antibodies targeting either the CGRP-R or the CGRP peptide might show sexually dimorphic outcomes for acute and preventive therapy has not been established.
METHODS: We conducted a subpopulation analysis of available published data from FDA reviews to evaluate potential sex differences in the response rates of ubrogepant, rimegepant and zavegepant for acute migraine therapy. Available data from FDA reviews of erenumab, fremanezumab, galcanezumab and eptinezumab, approved CGRP-R and CGRP monoclonal antibodies and of atogepant were examined for prevention outcomes based on patient sex. Preventive outcomes were analyzed separately for patients with episodic migraine and chronic migraine.
RESULTS: In women, the three approved gepants produced statistically significant drug effects regardless of dose tested on the FDA mandated co-primary endpoints, the proportion of patients achieving two-hour pain-freedom and the proportion of patients free of their most bothersome symptom at two hours post-dose. In women, the average placebo-subtracted two-hour pain-freedom proportion was 9.5% (CI: 7.4 to 11.6) and the average numbers needed to treat was 11. The free from most bothersome symptom at two hours outcomes were also significant in women. The gepant drugs did not reach statistically significant effects on the two-hour pain-freedom endpoint in the men, with an average drug effect of 2.8% (CI: -2.5 to 8.2) and an average number needed to treat of 36. For freedom from most bothersome symptom at two hours post-dose endpoint, differences were not significant in male patients. The treatment effect in each of the gepant studies was always numerically greater in women than in men. In evaluation of prevention outcomes with the antibodies or atogepant using the change from the specified primary endpoint (e.g., monthly migraine days), the observed treatment effect for episodic migraine patients almost always favored drug over placebo in both women and men. For chronic migraine patients the treatment effects of antibodies were similar in men and women and always favored the drug treated group.Conclusion/Interpretation: Small molecule CGRP-R antagonists are effective in acute migraine therapy in women but available data do not demonstrate effectiveness in men. CGRP-targeting therapies are effective for migraine prevention in both male and female episodic migraine patients but possible sex differences remain uncertain. In male and female chronic migraine patients, CGRP/CGRP-R antibodies were similarly effective. The data highlight possible differential effects of CGRP targeted therapies in different patient populations and the need for increased understanding of CGRP neurobiology in men and women.
This invention pertains to the discoveries that orexin and/or CRF increase NMDAR (N-methyl-D-aspartate receptor)-mediated currents at excitatory synapses onto a subset of dopamine cells in the ventral tegmental area (VTA) in the mammalian brain. The orexin effect can be blocked by an orexin receptor type 1(OXRl). The CRF effect can be blocked by a CRF receptor 2 (CRF-R2) antagonist or by an inhibitor of the CRF-binding protein (CRF-BP). Methods are provided that exploit these discoveries to modulate NMDAR-mediated currents in vivo and in vitro and to screen for modulators (upregulators or downregulators) of NMDA-mediated currents. In vivo methods include the use of modulators of the orexin and CRF pathways to of mitigate a symptom of substance abuse. The invention also provides methods and compositions for co-administration of modulators that act via the orexin and CRF pathways.
A male patient in his 30s presented with complaints of acute abdominal pain, black stools and red-coloured urine. CT revealed thrombi in the splenic and left renal veins, leading to infarctions. An endoscopy displayed scalloping of the duodenal folds, indicative of intestinal malabsorption syndrome (IMS). Histopathological examination confirmed IMS. Due to the presence of intravascular haemolysis, haemoglobinuria and thrombotic complications, paroxysmal nocturnal haemoglobinuria (PNH) was suspected and subsequently confirmed by flow cytometry. Thus, a diagnosis of classic PNH with IMS and thrombotic complications was established. This unique case highlights the coexistence of PNH and IMS, resembling the complement hyperactivation, angiopathic thrombosis and protein-losing enteropathy disease, suggesting potential shared pathophysiology.
The subject matter disclosed herein is generally directed to detecting and modulating novel gene signatures for the treatment and prognosis of cancer. The novel gene signatures predict overall survival in cancer and can be targeted therapeutically. Specifically, disclosed is a resistance program identified by a comprehensive single-cell profiling study in melanoma patients, which was validated in two large validation cohorts. Using a large-scale in silico prediction, CDK4/6 inhibitors were identified as a class of drugs that may reverse this resistance program. These predictions were validated in melanoma cell lines, patient-derived co-culture models, and melanoma in vivo models, which show that the combination of abemaciclib and immune checkpoint blockade (ICB) overcome intrinsic drug resistance. The present invention provides for detecting an immunotherapy resistance signature and modulating the signature with CDK4/6 inhibition. Also provided is a novel phased immunotherapy and CDK4/6 inhibitor combination therapy regimen.
Positive fluid status has been consistently associated with worse prognosis in critically ill adult patients. Daily and cumulative fluid balance (FB) is a routine nursing activity in intensive care unit (ICU). In view of the potential for errors in the calculation of FB totals and the problem of accounting for insensible fluid losses, measurement of body weight (BW) changes is an alternative non-invasive method commonly used for estimating body fluid status. Its accuracy over FB assumes a one kilogram change in BW equates to a one liter gain or loss in body fluid volume. However, observational studies showed poor agreement between those measurements, particularly among individuals staying more than a week in ICU possibly due to muscle and fat loss as well as bone demineralization. The objective of the study is to compare the measurements of FB and BW over time and to assess correlation with ICU mortality.
Initially, an oral dose of 25 mg/day should be tried in children aged 6 and older. Medication should be given one hour before bedtime. If a satisfactory response does not occur within one week, increase the dose to 50 mg nightly in children under 12 years; children over 12 may receive up to 75 mg nightly. A daily dose greater than 75 mg does not enhance efficacy and tends to increase side effects. Evidence suggests that in early night bedwetters, the drug is more effective given earlier and in divided amounts, i.e., 25 mg in midafternoon, repeated at bedtime. Consideration should be given to instituting a drug free period following an adequate therapeutic trial with a favorable response, Dosage should be tapered off gradually rather than abruptly discontinued; this may reduce the tendency to relapse. Children who relapse when the drug is discontinued do not always respond to a subsequent course of treatment.

A dose of 2.5 mg/kg/day should not be exceeded, ECG changes of unknown significance have been reported in pediatric patients with doses twice this amount.

The safety and effectiveness of Imipramine hydrochloride tablets, USP as temporary adjunctive therapy for nocturnal enuresis in children less than 6 years of age has not been established.
PURPOSE: The purpose of this study was to study the effects of the severity of preoperative bone marrow oedema (BME) on the postoperative short-term outcomes following bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLTs) and to propose a new metric that combines volume and signal density to evaluate BME.
METHODS: Sixty-five patients with symptomatic OLTs (<100 mm2) and preoperative BME, who received BMS in our institution from April 2017 to July 2021 with follow-ups of 3, 6 and 12 months, were analysed retrospectively. The area, volume and signal value of the BME were collected on preoperative magnetic resonance imaging. The enroled patients were divided into two groups according to the BME index (BMEI), which was defined as the product of oedema relative signal intensity and the relation of oedema volume to total talar volume. Visual analogue scale, American Orthopedic Foot and Ankle Society (AOFAS), Tegner, Foot and Ankle Ability Measure (FAAM)-activities of daily living (ADL) and Sports scores were assessed before surgery and at each follow-up. The relationship between the scores and the volume, relative signal intensity and BMEI was explored.
RESULTS: Sixty-five patients with preoperative BME were divided into the mild (n = 33) and severe (n = 32) groups based on the BMEI. A significant difference was found for each score with the general linear model for repeated measures through all follow-up time points (p < 0.001). For the preoperative and 12-month postoperative changes of the enroled patients, 53 patients (81.5%) exceeded the minimal clinically important difference of AOFAS and 26 (40.0%) exceeded that of FAAM-sports in this study. The mild group showed significantly more improvement in AOFAS scores at 12 months (89.6 ± 7.0 vs. 86.2 ± 6.2) and FAAM-ADL scores at 6 months (83.6 ± 7.6 vs. 79.7 ± 7.7) and 12 months (88.5 ± 8.5 vs. 84.4 ± 7.7) than the severe group (p < 0.05). No significant difference of all the scores between the groups was found at 3 months. No significant correlation was found in each group between BMEI and clinical outcomes.
CONCLUSION: The severity of the preoperative BME negatively affected short-term clinical outcomes following arthroscopic BMS for OLTs. Worse clinical outcomes were shown at postoperative 6 and 12 months in patients with a high preoperative BMEI, which could be a favourable parameter for assessing the severity of BME and assist in developing personalised rehabilitation plans and determining the approach and timing of surgery.
LEVEL OF EVIDENCE: Level III.
Almost one-half of adults have hypertension, and blood pressure is poorly controlled in a third of patients despite the use of multiple drugs, likely because of mechanisms that are not affected by current treatments. Hypertension is linked to oxidative stress; however, common antioxidants are ineffective. Hypertension is associated with inactivation of key intrinsic mitochondrial antioxidant, superoxide dismutase 2 (SOD2), due to hyperacetylation, but the role of specific SOD2 lysine residues has not been defined. Hypertension is associated with SOD2 acetylation at lysine 68, and we suggested that deacetylation mimetic mutation of K68 to arginine in SOD2 inhibits vascular oxidative stress and attenuates hypertension. To test this hypothesis, we have developed a new deacetylation mimetic SOD2-K68R mice. We performed in vivo studies in SOD2-K68R mice using angiotensin II (ANG II) model of vascular dysfunction and hypertension. ANG II infusion in wild-type mice induced vascular inflammation and oxidative stress and increased blood pressure to 160 mmHg. SOD2-K68R mutation completely prevented increase in mitochondrial superoxide, abrogated vascular oxidative stress, preserved endothelial nitric oxide production, protected vasorelaxation, and attenuated ANG II-induced hypertension. ANG II and cytokines contribute to vascular oxidative stress and hypertension. Treatment of wild-type aortas with ANG II and cytokines in organoid culture increased mitochondrial superoxide twofold, which was completely prevented in aortas isolated from SOD2-K68R mice. These data support the important role of SOD2-K68 acetylation in vascular oxidative stress and pathogenesis of hypertension. We conclude that strategies to reduce SOD2 acetylation may have therapeutic potential in the treatment of vascular dysfunction and hypertension.NEW & NOTEWORTHY Essential hypertension is associated with hyperacetylation of key mitochondrial antioxidant SOD2; however, the pathophysiological role of SOD2 acetylation has not been defined. Our animal study of angiotensin II hypertension model shows that deacetylation mimetic SOD2-K68R mutation prevents pathogenic increase in vascular mitochondrial superoxide, abrogates vascular oxidative stress, preserves endothelial nitric oxide, protects endothelial-dependent vasorelaxation, and attenuates hypertension. These data support the important role of SOD2-K68 acetylation in vascular oxidative stress and the pathogenesis of hypertension.
PURPOSE:To obtain a hair tonic, containing an extract of peppermint (Mentha piperita L.) and having excellent alopecia preventing and hair growing effects. CONSTITUTION:This hair tonic contains an extract prepared by extracting a leaf or the whole herb of peppermint with a solvent (e.g. hot water-ethanol) as an active ingredient in an amount of 0.005-20-wt.% expressed in terms of a dried substance in the total amount of the hair tonic. Combinations of the extract of the peppermint further with an anionic surfactant and a surfactant having nitrogen in the molecule other than the anionic surfactant; the extract of the peppermint with an amphoteric surfactant, a semipolar surfactant and a nonionic surfactant having nitrogen in the molecule and the extract of the Shiraia bumbusicola with an amine oxide provide an excellent hair tonic. The hair tonic is prepared into a form applicable to the exodermis such as a liquid, an emulsion or an ointment, directly applied to or sprayed on the skin and percutaneously administered. The daily dose thereof is 0.01-100mg/kg.
Our prior Stage III Randomized Clinical Trial (n=1496) evaluating ethnic differences in response to brief intervention showed that, compared to non-Latinxs Whites, Latinxs were more likely to reduce alcohol use in response to standard brief alcohol interventions that are not adapted to be culturally responsive (NA-BMI) versus treatment as usual1. In Stage I Community Based Participatory Research (Stage I CBPR), we developed a culturally informed brief motivational intervention (CI-BMI) which adopts a harm reduction approach and focuses on reducing alcohol problems and increasing treatment utilization 2. Through a flexible core approach, CI-BMI introduces substantial modifications to standard brief alcohol interventions to be culturally responsive and is theoretically grounded in self-determination theory (SDT)3-5. The result of Stage I CBPR was CI-BMI which 1) leverages cultural values and strengths while addressing the process of acculturation and acculturative stress; 2) is explicitly designed to meet the basic psychological needs of autonomy, relatedness, and competence by supporting autonomy to enhance autonomous motivation to change drinking behavior; and 3) focuses on harm reduction. Our Stage I CBPR (n=87) demonstrated that CIBMI is feasible and acceptable in pretesting in a Level I Trauma Center5. We hypothesize that CI-BMI will lead to increased engagement in protective drinking behaviors, fewer alcohol problems as well as reduce barriers to help seeking and increase treatment utilization among underserved, non-treatment seeking Latinxs who engage in at risk drinking and are seriously injured. The proposed Stage II Efficacy Trial of CI-BMI will randomize 600 Latinxs admitted to a Level I Trauma Center at University Medical Center in El Paso, Texas to either NA-BMI or CI-BMI conducted by research staff from The University of Texas El Paso. Following admission for medical treatment of an injury, eligible Latinx patients will be those who screen positive for drinking at the time of their injury or engage in at risk drinking. The primary aims of the proposed study are to

1) test the efficacy of CI-BMI in comparison to NA-BMI on alcohol related harm reduction behaviors, alcohol problems, barriers to help seeking and treatment utilization among non-treatment seeking Latinxs and 2) examine the theoretically informed mechanism of behavior change based on SDT including providing autonomy support to meet the basic psychological needs that enhance autonomous motivation. Because the psychological processes underlying the intrasession mechanisms of change remain poorly understood, CI-BMI based on SDT will significantly advance the science and practice of brief interventions6. In addition, planned secondary data analysis will assess the influence of multi-dimensional acculturation/enculturation orientations and acculturative stress on alcohol related outcomes. The results of this study will lead to a theoretically informed and culturally response brief motivation intervention with enhanced generalizability to effectively address alcohol related health disparities and treatment inequities among non-treatment seeking Latinxs.
Diabetes and cancer are two prevalent disorders, pose significant public health challenges and contribute substantially to global mortality rates, with solely 10 million reported cancer-related deaths in 2020. This review explores the pathological association between diabetes and diverse cancer progressions, examining molecular mechanisms and potential therapeutic intersections. From altered metabolic landscapes to dysregulated signaling pathways, the intricate links are delineated, offering a comprehensive understanding of diabetes as a modulator of tumorigenesis. Cancer cells develop drug resistance through mechanisms like enhanced drug efflux, genetic mutations, and altered drug metabolism, allowing them to survive despite chemotherapeutic agent. Glucose emerges as a pivotal player in diabetes progression, and serving as a crucial energy source for cancer cells, supporting their biosynthetic needs and adaptation to diverse microenvironments. Glycation, a non-enzymatic process that produces advanced glycation end products (AGEs), has been linked to the etiology of cancer and has been shown in a number of tumor forms, such as leiomyosarcomas, adenocarcinomas, and squamous cell carcinomas. Furthermore, in aggressive and metastatic breast cancer, the receptor for AGEs (RAGE) is increased, which may increase the malignancy of the tumor. Reprogramming glucose metabolism manifests as hallmark cancer features, including accelerated cell proliferation, angiogenesis, metastasis, and evasion of apoptosis. This manuscript encapsulates the dual narrative of diabetes as a driver of cancer progression and the potential of repurposed antidiabetic drugs as formidable countermeasures. The amalgamation of mechanistic understanding and clinical trial outcomes establishes a robust foundation for further translational research and therapeutic advancements in the dynamic intersection of diabetes and cancer.
