The document summarizes the nervous system in humans. It describes the central nervous system as including the brain and spinal cord. The peripheral nervous system has nerve cells with axons that extend through the limbs. The peripheral nervous system has three divisions: somatic, sympathetic, and parasympathetic. Neurons transmit nerve messages while glial cells support and protect neurons. Neurons receive signals at dendrites, transmit signals along axons, and communicate between cells via neurotransmitters at synapses.

i3 Health

i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource. This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and Associate Division Director for Ambulatory Operations The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma. STATEMENT OF NEED Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL. Target Audience Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL). Learning Objectives 1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL 2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults 3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Physiology of Special Chemical Sensation of Taste

MedicoseAcademics

Title: Sense of Taste Presenter: Dr. Faiza, Assistant Professor of Physiology Qualifications: MBBS (Best Graduate, AIMC Lahore) FCPS Physiology ICMT, CHPE, DHPE (STMU) MPH (GC University, Faisalabad) MBA (Virtual University of Pakistan) Learning Objectives: Describe the structure and function of taste buds. Describe the relationship between the taste threshold and taste index of common substances. Explain the chemical basis and signal transduction of taste perception for each type of primary taste sensation. Recognize different abnormalities of taste perception and their causes. Key Topics: Significance of Taste Sensation: Differentiation between pleasant and harmful food Influence on behavior Selection of food based on metabolic needs Receptors of Taste: Taste buds on the tongue Influence of sense of smell, texture of food, and pain stimulation (e.g., by pepper) Primary and Secondary Taste Sensations: Primary taste sensations: Sweet, Sour, Salty, Bitter, Umami Chemical basis and signal transduction mechanisms for each taste Taste Threshold and Index: Taste threshold values for Sweet (sucrose), Salty (NaCl), Sour (HCl), and Bitter (Quinine) Taste index relationship: Inversely proportional to taste threshold Taste Blindness: Inability to taste certain substances, particularly thiourea compounds Example: Phenylthiocarbamide Structure and Function of Taste Buds: Composition: Epithelial cells, Sustentacular/Supporting cells, Taste cells, Basal cells Features: Taste pores, Taste hairs/microvilli, and Taste nerve fibers Location of Taste Buds: Found in papillae of the tongue (Fungiform, Circumvallate, Foliate) Also present on the palate, tonsillar pillars, epiglottis, and proximal esophagus Mechanism of Taste Stimulation: Interaction of taste substances with receptors on microvilli Signal transduction pathways for Umami, Sweet, Bitter, Sour, and Salty tastes Taste Sensitivity and Adaptation: Decrease in sensitivity with age Rapid adaptation of taste sensation Role of Saliva in Taste: Dissolution of tastants to reach receptors Washing away the stimulus Taste Preferences and Aversions: Mechanisms behind taste preference and aversion Influence of receptors and neural pathways Impact of Sensory Nerve Damage: Degeneration of taste buds if the sensory nerve fiber is cut Abnormalities of Taste Detection: Conditions: Ageusia, Hypogeusia, Dysgeusia (parageusia) Causes: Nerve damage, neurological disorders, infections, poor oral hygiene, adverse drug effects, deficiencies, aging, tobacco use, altered neurotransmitter levels Neurotransmitters and Taste Threshold: Effects of serotonin (5-HT) and norepinephrine (NE) on taste sensitivity Supertasters: 25% of the population with heightened sensitivity to taste, especially bitterness Increased number of fungiform papillae

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0). CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Alcohol_Dr. Jeenal Mistry MD Pharmacology.pdf

Dr Jeenal Mistry

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol that is rapidly distributed in the body and brain. Ethanol alters many neurochemical systems and has rewarding and addictive properties. It is the oldest recreational drug and likely contributes to more morbidity, mortality, and public health costs than all illicit drugs combined. The 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) integrates alcohol abuse and alcohol dependence into a single disorder called alcohol use disorder (AUD), with mild, moderate, and severe subclassifications (American Psychiatric Association, 2013). In the DSM-5, all types of substance abuse and dependence have been combined into a single substance use disorder (SUD) on a continuum from mild to severe. A diagnosis of AUD requires that at least two of the 11 DSM-5 behaviors be present within a 12-month period (mild AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria). The four main behavioral effects of AUD are impaired control over drinking, negative social consequences, risky use, and altered physiological effects (tolerance, withdrawal). This chapter presents an overview of the prevalence and harmful consequences of AUD in the U.S., the systemic nature of the disease, neurocircuitry and stages of AUD, comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and pharmacotherapies for AUD.

Novas diretrizes da OMS para os cuidados perinatais de mais qualidade

Prof. Marcus Renato de Carvalho

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva. Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade. Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal. Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural. Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis. É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais. O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada. Recomendamos muito. Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos. Esta publicação só está disponível em inglês até o momento.

ACUTE SCROTUM.....pdf. ACUTE SCROTAL CONDITIOND

DR SETH JOTHAM

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum. There are a number of conditions that present acutely, predominantly with pain and/or swelling A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle. Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction. The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent
