Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

This document describes the acute management of AV block.
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.

3. Men’s fertility potential depends on
female factors
• Assessment of tests and treatments for the male is
challenging due to inconsistent endpoints and the
observation that many of these endpoints are
dependent upon and measured from the female
partner.
• Ideally, the endpoint for fertility trials should be "live
birth or cumulative live birth (WHO, 2021)
8. Limitations of WHO Guideline
• 5 percentile and time-to-pregnancy (TTP) concept
• Not true reference values but recommends
acceptable levels.
• Day to day variation
• Functional ability of the sperms?
9. Sperm DNA
Fragmentation (SDF)
Infertile men with:
• Repeated IUI or IVF failure
• Recurrent spontaneous
miscarriages (ESHRE, 2018)
• Previous low fertilization,
cleavage or blastulation rate
• Varicocele with
normozoospermia
• Advanced male age (>40 y)
Significance of SDF
• Live birth after IUI/ IVF/
ICSI- ?
• Oocytes can repair the
damaged DNA
• Lack of standardization
• Lack of definitive treatment

• Grade 1: palpable during
Valsava manoeuvre, but not
otherwise.
• Grade 2: palpable at rest, but
not visible.
• Grade 3: visible at rest
25. Surgery for Varicocele
(EUA, 2018)
• Grade 3 varicocele
• Ipsilateral testicular atrophy
• Pain
• Abnormal semen parameters
• No other fertility factors in the couple
26. In couples seeking fertility with ART, varicocele repair
• may offer improvement in semen parameters
• may decrease level of ART needed
27. Cryptorchidism in adults (EUA, 2018)
• In adulthood, a palpable undescended
testis should NOT be removed because it
still produces testosterone.
• Correction of B/L cryptorchidism, even in
adulthood, can lead to sperm production in
previously azoospermic men
• Perform testicular biopsy at the time of
orchidopexy in adult- to detect germ cell
neoplasia in situ

35. Role Of Medical Therapy
(EUA, 2018, ASRM, 2020)
Hypogonadotropic
hypodonadism
•hCG 2000-5000 IU 3 times a week
•If hCG alone cannot restore spermatogenesis, FSH is
added 75-150 IU 3 times a week
•Serum testosterone and semen analysis every 1–2 months
•Usual time to recover 6 – 12 months (may take 24
months)
•Natural conception vs ART?
Idiopathic Male
infertility
CC
Tamoxifen
Letrozole
hCG
All empirical
Evidences?
Testosterone
supplementation
Strongly CONTRAINDICATED
Feedback inhibition on FSH, LH→ secondary
hypogonadism
Aromatase
inhibitors (Letrozole,
Anastrozole)
If T:E2 ratio <10 (T- ng/dl, E2- pg/ml)
36. Stories of Hypo/Hypo
• Delayed puberty
• Anosmia

•Nonfunctioning Pituitary macroadenoma →
Endoscopic surgery H/P Lymphocytic hypophysitis
•Started hCG f/b hMG by endocrinologist
•Sperm conc 1-2/ hpf
• 17 yr age, sudden testicular atrophy
• B/L testes 6 cc each

• may improve live birth rates
• clinical pregnancy rates may also increase.
• Overall, there is no evidence of increased risk of
miscarriage, however antioxidants may give more
mild gastrointestinal upsets
• Subfertilte couples should be advised that overall, the
current evidence is inconclusive.
40. • In some studies, AS was found to be
beneficial in reversing OS-related sperm
dysfunction and improving pregnancy rates.
• Still debatable due to the heterogeneity in
study designs and the multifactorial genesis of
infertility.
41. TMSC PR/CYCLE
10–20 million 18.29%
5–10 million 5.63%
<5million 2.7%
Guven et al, 2008;Abdelkader & Yeh, 2009
Hamilton etral., 2015
Criteria TMSC Treatment
Pre wash TMSC > 5 million IUI
Pre wash TMSC 1 - 5 million IVF
Pre wash TMSC <1 million ICSI
Male factor- IUI, IVF or ICSI?
42. TMSC <5 mil/ml and IUI
• Counsel before IUI
1. Double Ejaculate Kucuc et al., 2004; Oritz et al., 2016
2. “Trial IUI”- Post wash- IMSC Ombelet et al., 2014
3. IMSC >1 mil/ml → Further IUI
4. IMSC <1 mil/ml → ICSI
45. FNAC- role?
• Isolated foci of
spermatogenesis
ASRM, 2020
• Consider TESA in
indeterminate cases- NOT
NECESSARY
FSH >7.6 <7.6
Testicular long axis (cm) <4.6 >4.6
89% chance of NOA 96% chance of OA
57. Medical Therapy in Idiopathic
Azoospermia
• To improve the chance
of sperm retrieval
(Alkandari and Zini, 2021; Kumar,
2021; Holtermann et al., 2022).
• Sometimes, can lead to
appearance of sperms in
the ejaculate (Alkandari and
Zini, 2021; Kumar, 2021).
• hCG
• FSH
• CC
• Tamoxifen
• Letrozole
• Antioxidants??

63. Non-targeted investigations ?
• Delayed puberty
• Testo 100.86. FSH 28.33. LH 13.65. E2 27.83
• Testosterone injection started at puberty - sec sex charac, voice, genital size
improved
• MRI pitutary microadenoma
• GH, TSH, Cortisol, PRL, - all normal
64. Targeted female investigations
• If no risk factors for
tubal block- 3 cycles of
IUI, then tubal patency
test
• If risk factors- tubal
patency first
•Ovaries
•Tubes- IUI or IVF/ICSI?
66. 1. Meticulous semen analysis in a standard laboratory
2. Physical examination and rational investigations
3. Avoid non-evidence based drugs for long time
4. Antioxidants- May be useful in mild problem
5. Antioxidants- Not reliable in severe problem
6. Donor sperm is NOT the only solution
7. IUI or IVF/ICSI- depends on the overall assessment
