Swine flu is a respiratory disease. It is caused by the influenza viruses that infect the respiratory tract of pigs. It can lead to symptoms such as a barking cough, decreased appetite, nasal secretions, and listless behaviour; the virus can be transmitted to humans. The Swine flu vaccination or H1N1 vaccination is crucial to provide immunity against swine flu.

Bacteria of the genus Salmonella are highly adapted for growth in both humans and animals and cause a wide spectrum of disease.
The growth of S. Typhi and S. Paratyphi is restricted to human hosts, in whom these organisms cause enteric (typhoid) fever.
The remaining serotypes (non-typhoidal Salmonella or NTS) can colonize the gastrointestinal tracts of a broad range of animals, including mammals, reptiles, birds and insects.

ABSTRACT- INTRODUCTION- HIV/AIDS pandemic is responsible for the resurgence of Tuberculosis worldwide,
resulting in increased morbidity and mortality. Co-infection with HIV infection leads to difficulty in both the diagnosis
and treatment of Tuberculosis, increased risk of death, treatment failure and relapse.
OBJECTIVE- The present study highlights the correlation of Pulmonary Tuberculosis in HIV positive cases and its
association with CD4 count.
MATERIAL & METHODS- A total of 72 known case of HIV were screened for tuberculosis infection by clinical
examination, radiology & ZN staining.
RESULTS AND CONCLUSIONS- From our study 60 (83.33%) were diagnosed as tuberculosis and 12 (16.67%) were
negative. More common HIV infection in case of male 48 (66.67%). Out of 60 tuberculosis infection 53 (88.33%) were
diagnosed as Pulmonary Tuberculosis and 7 (11.67%) were diagnosed as Extrapulmonary Tuberculosis. The result of
study emphasizes that co-infection of tuberculosis in HIV/AIDS patient is a concern. There is direct correlation between
CD4 counts depletion and Pulmonary Tuberculosis in HIV/AIDS patients.
Key-words- Pulmonary Tuberculosis, HIV, AIDS, CD4 count
The 2009 flu outbreak in humans is due to a new strain of influenza A virus subtype H1N1 that derives in part from human influenza, avian influenza, and two separate strains of swine influenza.
The new virus has made the jump from pigs to humans and has demonstrated it can also pass from human to human. This is why it is demanding so much attention from health authorities. The virus passes from human to human like other types of flu, either through coughing, sneezing, or by touching infected surfaces, although little is known about how the virus acts on humans.

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
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.

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.

Major Antigenic Change, Forming new sub-type (Subtype A + Subtype B –> New Subtype), One or Two Viruses are Involved, Occurs once in a time, May jump from one species to another (animal-human), Large change in nucleotides of RNA, Occurs as a results of genome reassortment between difference subtypes, An antigenic change which results in drastic or dramatic alternation in HA (hemagglutinin) or NA (neuraminidase) subtypes, Occurs only in Influenza Virus A, Give rise to pandemics, which occurs irregularly and unpredictably.

Sometimes anigenic shifts takes place in different years randomly
Haemagglutinin causes red blood cells to clump together and binds the virus to the infected cell. Neuraminidase are a type of glycoside hydrolase enzyme which help to move the virus particles through the infected cell and assist in budding from the host cells.
