Chemotherapy uses drugs to treat diseases like cancer throughout the body. Antibiotics are classified based on their spectrum of activity, mechanism, and source. Penicillin is a natural antibiotic while semisynthetic penicillins are derived from it. They are further classified based on properties like resistance to penicillinase. Broad spectrum antibiotics treat a wide range of bacteria while narrow spectrum antibiotics treat specific types. Chemotherapy drugs are also classified into groups like beta-lactams, quinolones, and others based on their structure and antimicrobial activity.
The medical term for tumor (or) cancer is Neoplasm, Which means a relatively autonomous growth (or) un corodinated cell proliferation of body tissue.The branch of medicine which deals with the excessive study of neoplasm (tumor) and its development diagnosis and treatment is called “Oncology.”
The term cancer was translated from a Latin word carcino i.e. Crab by celsus.
For the first time Hippocrates coined the Greek word Karkinos i.e. (crab/cray fish) for malignant breast cancer
Agents used to treat such abnormal cell productions are known as anti neoplastic agents.they are 1.Alkylating agents:-
Nitrogen mustards
Cyclophosphamide
Meclorethamine
2.Antimetabolites:-

Skin sensitivity may develop with Penicillin or streptomycin causing rashes.
Serious toxic effect may occur due to streptomycin on the vestibular & auditory nerve causing vertigo & deafness
Drug Resistance: Many bacteria soon develops resistance to particular drug after a period of treatment, so that the bacteria will not respond to the same drug for example tubercle bacillus develops resistance to streptomycin quickly.
Super infection: The antibiotics given by mouth kill the normal bacteria inhibiting the alimentary canal and permits the over growth of other insensitive organisms which can cause serious complications. Eg. Fungus cause thrush which may go to the lungs with fatal results.
Hypersensitivity Reaction: Chemotherapeutic agents can cause Hypersensitivity reactions from mild rashes to serve anaphylactic shock. Eg. Penicillin & Sulphonamides.
Vitamin Deficiency: Alteration in vitamin formation and absorption from the bowel take place . So there is deficiency of Vitamin B complex and Vitamin K.
Anemia: In susceptible persons chloramphenicol may produce Aplastic anemia or agranulocytosis. (Action must be taken through proper history about previous drug reaction before administering penicillin sulphonamide and cephalosporin

antibiotics are necessary to treat infections and chemotherapeutic agents are also used for this purpose. Chemotherapeutic agents are also used in the treatment of cancers. These therapeutic agents have limitations, specific action and a set mode of action. We can say that they are selective. The antibiotics are natural as well as synthetic in nature and have specificity for action against the microorganisms. Chemotherapeutic agents are chemical in nature and are synthesised in labs. They are less selective in action.

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
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.

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.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...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
