Background: It has been reported that general adiposity in adulthood and early adulthood, and greater height may increase the risk of almost all types of lympho-haematopoietic cancers while a study done in MD Anderson found that obesity and adult weight gain are independent risk factors for CML however no study evaluated the role of obesity in the disease progression while more studies investigate the impact of translocation types. Method: We conducted a retrospective analysis of the files of 37 patients being treated in our center for CML in chronic phase (CMP-CP) with known BCR-ABL1 breakpoints, Results: patients’ management and response assessment was done based on ELN 2013 guidelines. Analysis is done based on two main groups, obese vs normal BMI, and then based on BCR-ABL1 transcripts: e13a2 vs e14a2. Although the number of cases is limited, in the patient-cohort studied an e14a2 BCR-ABL1 transcript type / normal body weight was associated with an inferior outcome when compared to e13a2 transcript / obesity groups Conclusion: our finding suggest the need to enlarge the series to better evaluate a potential role of altered metabolism and/or specific transcripts in the response to TKI in CML.

Treatment Of Obesity

Over the past few decades there has been a significant increase in the prevalence of obesity in both children and adults. Obesity is a disease that has reached epidemic levels on a global scale. The development of obesity is associated with both environmental and genetic factors. Recent studies indicate that intestinal microorganisms play an important function in maintaining normal body weight. One of the objectives in the gut microbiota research is to determine the role it plays and can it be a reliable biomarker of disease risk, including the predisposition to obesity. This article discusses (1) the role of prebiotics and gut microbiota in maintaining a healthy body weight and (2) potential influence on the gut microbiota in the prevention and treatment of obesity.

Transcript Type

Objective It is debatable whether BCR-ABL1 transcript type has an impact on outcome of treatment of patients with CML, and it is not widely studied whether body weight influences response to treatment. In this study, we tried to find out if any of these factors has an impact on response to treatment and outcome. Methodology We conducted a retrospective analysis of the files of 79 patients being treated in our center for CML with known BCR-ABL1 breakpoints, and patients’ management and response assessment was done based on ELN 2013 guidelines. The analysis was performed based on two main groups, obese vs. normal BMI, and then based on BCR-ABL1 transcripts: e13a2 vs. e14a2. Cumulative incidence of MMR, CCyR, and DMR were estimated using the Kaplan–Meier survival curve method, and comparisons between groups were performed by the Log-rank/Gray test methods. Results/conclusion In the patient-cohort studied, there was no statistically significant difference in molecular response between patients with CML based on body weight or transcript type although patients in the obesity group achieved higher and faster MMR with no statistical significance.

В настоящий момент проблема СOVID-19 приводит к развитию и обострению сердечно-сосудистой патологии, сопровождающейся изменениями гемодинамики. Цель исследования - оценка зависимости изменений гемодинамики у пациентов с COVID-19 от алиментарно-конституционального ожирения. Методика. Исследование выполнено у 73 пациентов обоего пола с внебольничной полисегментарной вирусно-бактериальной пневмонией на фоне СOVID-19. Пациенты были разделены на 3 группы по индексу массы тела. В 1-ю группу вошли пациенты без избытка массы тела, 2-ю составили пациенты с избыточной массой тела, 3-ю - с ожирением 1 степени. Использован комплекс аппаратно-программного неинвазивного исследования центральной гемодинамики методом объемной компрессионной осциллометрии «КАП ЦГ осм- «Глобус» (Россия). Результаты. У пациентов с СOVID-19, страдающих ожирением I степени (30,0 - 34,9 кг/м2). выявлено статистически значимое снижение сердечного индекса относительно лиц с нормальной массой тела (на 10,8%, p=0,010). Пациенты с избытком массы тела имели более высокое диастолическое давление (на 10,5%, p=0,011) Показатель периферического сосудистого сопротивления у пациентов с СOVID-19 без избыточной массы тела был на 16.5% ниже, чем у пациентов с ожирением 1 степени. Удельное периферическое сопротивление сосудов у пациентов 1-й группы было на 10.3% меньше, чем у пациентов с избыточной массой тела. Податливость сосудистой стенки у пациентов 1-й группы была ниже на 22.5%, чем у пациентов с СOVID-19 и ожирением 1 степени. Заключение. У пациентов с внебольничной полисегментарной вирусно-бактериальной пневмонией на фоне СOVID-19 при ожирении 1 степени и избыточной массе тела выявляются значимые изменения гемодинамики относительно больных с нормальной массой тела. Background: Obesity is one of the most common causes of comorbidities worldwide. During the COVID-19 pandemic, development and increasing severity of cardiovascular disorders associated with hemodynamic changes has become increasingly relevant. Aims: The study aimed to evaluate the hemodynamic changes in COVID-19 patients depending on the severity of their exogenous constitutional obesity. Methods. 73 male and female patients with community-acquired polysegmental pneumonia of viral and bacterial origin associated with COVID-19 were enrolled in the study. The patients were allocated to three groups depending on the value of their body mass index (BMI). Group 1 included patients with normal body weight; Group 2 included overweight patients, and Group 3 included patients with grade 1 obesity (BMI 30.0-34.9 kg/m2). The measurements were performed using a technique of volumetric compression oscillometry on a non-invasive hemodynamic monitoring system KAP CG osm (Globus, Russia). Results. COVID-19 patients with grade 1 obesity (BMI 30.0-34.9 kg/m2) demonstrated a statistically significant 10.8% decrease in the cardiac index compared to patients with normal body weight (p=0.010). Overweight patients had 10.5% higher diastolic blood pressure (p=0.011). Peripheral vascular resistance (PVR) in COVID-19 patients with normal body weight was 16.5% lower than in patients with grade 1 obesity. PVR adjusted for body surface area in patients with normal body weight was 10.3% lower than in overweight patients. The compliance of the vascular wall in Group 1 patients was 22.5% lower than in COVID-19 patients with grade 1 obesity. Conclusion. COVID-19 patients with community-acquired, polysegmental pneumonia of viral and bacterial origin demonstrate significant hemodynamic changes compared to patients with normal body weights.

The Impact

The NLSY97 data were used to explore the patterns of developmental trajectories of body weight in adolescence and how they affected the likelihood of college completion in young adulthood among 2,275 youths aged 13 and 14 in Wave 1. A strong weight trajectory gradient was found for rates of college completion. The study further explored the role of non-cognitive traits in the association between weight trajectories and college attainment. Non-cognitive traits were found to partially mediate the impact of certain weight trajectories on the likelihood of college completion. Some moderating effects of conscientiousness were also found. The findings from the gender and weight trajectory interaction terms showed that a stronger negative impact of weight trajectory on college completion is only observed for women in the late-teen-onset overweight group. This study highlights the importance of using a longitudinal weight measure and the role of non-cognitive traits in adolescent obesity research.

The Impact

Acute lymphoblastic leukemia (ALL) with t(4;11)(q21;q23) - KMT2A-AFF1 is associated with a poor prognosis. The impact of KMT2A rearrangements other than t(4;11) is uncertain and the benefit of allogeneic stem cell transplant (HSCT) is unclear. We reviewed adult patients with ALL treated at our institution from 1984 to 2019 and identified 50/1102 (5%) with KMT2A rearrangement: 42 (84%) with t(4;11)/KMT2A-AFF1 and 8 (16%) with other gene partners. The median age was 45 years old (range, 18 - 78 years); median white blood cell count was 109.0 x 109/L (range, 0.5 - 1573.0). The complete remission (CR) rate was 88% and the rate of measurable residual disease negativity by flow cytometry at CR was 41% (76% overall during follow-up). At the last follow-up, 14 patients were alive. The 5-year overall survival (OS) rate was 18% (95% CI, 9 - 35%) with no difference between t(4;11) and other KMT2A rearrangements (p=0.87). In a 4-month landmark analysis, the 5-year OS rate was 32% (95% CI, 14 - 70%) in patients who underwent HSCT versus 11% (95% CI, 3 - 39) in others (p=0.10). Our study confirms the poor prognosis of ALL with any KMT2A rearrangement and the role of HSCT in these patients.

Abstract Attention (i.e., task relevance) and expectation (i.e., signal probability) are two critical top-down mechanisms guiding perceptual inference. Attention prioritizes processing of information that is relevant for observers’ current goals. Prior expectations encode the statistical structure of the environment. Research to date has mostly conflated spatial attention and expectation. Most notably, the Posner cueing paradigm manipulates spatial attention using probabilistic cues that indicate where the subsequent stimulus is likely to be presented. Only recently have studies attempted to dissociate the mechanisms of attention and expectation and characterized their interactive (i.e., synergistic) or additive influences on perception. In this review, we will first discuss methodological challenges that are involved in dissociating the mechanisms of attention and expectation. Second, we will review research that was designed to dissociate attention and expectation in the unisensory domain. Third, we will review the broad field of crossmodal endogenous and exogenous spatial attention that investigates the impact of attention across the senses. This raises the critical question of whether attention relies on amodal or modality-specific mechanisms. Fourth, we will discuss recent studies investigating the role of both spatial attention and expectation in multisensory perception, where the brain constructs a representation of the environment based on multiple sensory inputs. We conclude that spatial attention and expectation are closely intertwined in almost all circumstances of everyday life. Yet, despite their intimate relationship, attention and expectation rely on partly distinct neural mechanisms: while attentional resources are mainly shared across the senses, expectations can be formed in a modality-specific fashion.

The role of beta-endorphin in the development of several obesity syndromes was examined. Adult female hooded rats received ventromedial hypothalamic lesions, dorsolateral tegmental lesions, parasagittal hypothalamic knife cuts, intraventricular 5,7-dihydroxytryptamine, ovariectomy, control surgery, or were deprived to 75% of normal body weight. Dose-dependent suppression of food intake by the opiate antagonist naloxone (0.5, 1.8, 6.8, or 25.0 mg/kg, ip) was measured during once-daily 4-h food access periods. No difference was found among the groups at any dose. Pituitary beta-endorphinlike immunoreactivity (BELI) was substantially decreased in knife-cut rats, but was unaltered by other treatments. Obesity had no effect on BELI. In another experiment, rats made obese by prolonged maintenance on palatable foods had elevated pituitary BELI levels. Feeding mechanisms involving opioid peptides do not appear to be of etiological significance in the syndromes examined.

Background: The recommendations for routine preoperative esophagogastroduodenoscopy (EGD) in patients qualified for bariatric surgeries are still a matter of debate. The aim of this study was to analyze the pathologies on preoperative EGD in patients qualified for bariatric surgeries. Materials and Methods: This study included 222 patients, divided into two groups. The obesity group consisted of patients with obesity (BMI ≥ 40 kg/m2), for whom EGD was a routine part of the preparation for laparoscopic sleeve gastrectomy (LSG). The control group of patients with normal body weight (BMI) qualified for EGD because of gastrointestinal ailments. Results: Regarding preoperative EGD in patients qualified for bariatric surgeries, we analyzed the prevalence of endoscopic pathologies in various gastrointestinal tract segments. Patients with obesity were shown to present with esophageal pathologies significantly more often than persons in the control group (n = 23, 20.91% vs. n = 12, 10.91%, p = 0.042). The odds ratio of esophageal pathologies in patients with obesity versus the control group equaled 2.15 (95%CI: 1.01–4.59). In turn, the odds ratio of duodenal pathologies in patients from the control group was 3.31 (95%Cl: 1.16–9.47), which means that persons from this group were approximately three times more likely to be diagnosed with those pathologies compared to obese patients. Moreover, patient sex was a significant predictor of duodenal pathologies, with an odds ratio of 4.03 (95%CI: 1.53–10.61). Conclusions: Preoperative EGD can identify a broad spectrum of pathologies in obese patients, which suggests a routine examination before bariatric surgery.

Autophagy is a highly regulated multi-step process that occurs at the basal level in almost all cells. Although the deregulation of the autophagy process has been described in several pathologies, the role of autophagy in cancer as a cytoprotective mechanism is currently well established and supported by experimental and clinical evidence. Our understanding of the molecular mechanism of the autophagy process has largely contributed to defining how we can harness this process to improve the benefit of cancer therapies. While the role of autophagy in tumor resistance to chemotherapy is extensively documented, emerging data point toward autophagy as a mechanism of cancer resistance to radiotherapy, targeted therapy, and immunotherapy. Therefore, manipulating autophagy has emerged as a promising strategy to overcome tumor resistance to various anti-cancer therapies, and autophagy modulators are currently evaluated in combination therapies in several clinical trials. In this review, we will summarize our current knowledge of the impact of genetically and pharmacologically modulating autophagy genes and proteins, involved in the different steps of the autophagy process, on the therapeutic benefit of various cancer therapies. We will also briefly discuss the challenges and limitations to developing potent and selective autophagy inhibitors that could be used in ongoing clinical trials.
