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!

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.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

26. Failure to Output
• Occurs when no PM spike is present
• This may be due to battery failure, lead fracture,
a break in lead insulation, oversensing (inhibiting),
poor lead connection at the take-off from the PM,
and "cross-talk" (when A output is sensed by a V
lead in a dual-chamber PM).
Transvenous Pacemaker
27. Failure to Capture
A spike not followed by either a V complex
- lead fracture
- lead dislodgement
- elevated PM threshold
- MI at the lead tip
- certain AADs (eg, flecainide)
- metabolic abnormalities (hyper-k+
, acidosis, alkalosis)
- cardiac perforation
- poor lead connection at the take-off from the
generator
- improper amplitude or pulse width settings.
Transvenous Pacemaker
28. Sensing
• Definizione
- capacità del PM di percepire un segnale elettrico
intrinseco, in funzione dell’ampiezza, dello Slew-rate,
della frequenza del segnale e della posizione degli
elettrodi.
• Sensibilità programmata
- Indica il minimo segnale intracardiaco che il PM
percepisce per attivare la risposta del PM
(inibito o triggerato).

35. Oversensing
• When a PM incorrectly senses electrical activity
and is inhibited from correctly pacing.
• This may be due to muscular activity (particularly
oversensing of the diaphragm or pectoralis
muscles), electromagnetic (EM) interference, or
lead insulation breakage.
Transvenous Pacemaker
37. Undersensing
• When a PM incorrectly misses intrinsic
depolarization and paces despite intrinsic activity.
• This may be due to poor lead positioning, lead
dislodgment, magnet application, low battery
states, or MI.
• Management is similar to that for other types of
failures.
Transvenous Pacemaker
38. • A final category of PM failures is termed operative
• This includes malfunction due to mechanical
factors, such as PNX, pericarditis, infection, skin
erosion, hematoma, lead dislodgment, and venous
thrombosis.
• Treatment depends on the etiology.

Transcutaneous PM (TCP)
44. Access Pacer (Green) mode
The Pacer mode is accessed by
turning the Selector Switch
counter-clockwise
• Milliamps are the type of current
which are utilized in this mode
• No AED capability or
ANALYZE button can be used in
this mode
Transcutaneous PM (TCP)
45. Pacer Mode
• Pacer markers (PPM) indicate
the rate set to attempt to capture
the ventricle
• Default settings of 70 PPM and
0 mA are displayed upon access
of Pacer Mode
• To increase or decrease pacer
marker (PPM) turn the Pacer
Rate Dial
Transcutaneous PM (TCP)
46. Pacer Mode: Output Dial
• Turn the Pacer Output dial to
adjust the level of discharged
milliamps.
• If capture is achieved, the PPM
will have a wide complex
reflecting ventricular
contraction following the thin
PPM rate marker
Transcutaneous PM (TCP)
47. Pulse Duration
• Pulse duration is the time of impulse stimulation.
• Early TCPs used short (1-2 ms) duration impulses.
Such impulses resembled the action potential (AP)
and preferentially stimulated skeletal muscle.
• In contrast, cardiac muscle APs are much longer,
requiring 20-40 msec to reach maximum.
Transcutaneous PM (TCP)
48. Current
• Using a longer pulse duration and larger electrodes
permits pts to tolerate higher applied current.
• 100 mA of current applied over an average (50 Ώ
resistance) chest for 20 ms will deliver 0.1 J. This is
well below the 1-2 J required to cause an
uncomfortable tingling sensation in the skin.
• The force of skeletal muscle contraction, not the
electric current, determines TCP discomfort. Current
TCPs are capable of delivering up to 140-200 mA
tolerably.
Transcutaneous PM (TCP)
49. Definition of Capture:
Electrical and Mechanical
• Electrical capture: Every PPM
(pacer rate indicator) is followed
by a larger complex (QRS) which
indicates ventricular contraction
• Mechanical capture: When an
associated pulse is created with
the electrical capture. Pulse rate
should be PPM rate
• Once electrical and mechanical
capture has been confirmed, dial
the mA up 10% from capture
threshold as a safety margin
Transcutaneous PM (TCP)
50. Pacing Mode:
Ability to Perform 3 Types of Ventricular Pacing
1.) Demand Pacing:
Most frequent form of ventricular pacing. The PPM is set above
patient’s rate (or lack thereof) and the Pacer Output dial is turned to
increase the mA in attempt to obtain capture and pace the ventricles.
2.) Stand-by Pacing:
Setting the PPM and Pacer output at a back-up rate less than a
patient’s intrinsic heart rate. The PPM will initially be set above the
patients heart rate and pacer output (mA) is increased to achieve 100%
capture. The PPM is then decreased to desired rate below the patients
intrinsic heart rate. Should the HR drop, the stand-by pacer will
initiate impulses and begin to pace.
Transcutaneous PM (TCP)
51. 3.) Asynchronized Pacing:
Rarely used. This form of pacing is performed when no ECG electrodes can be
placed due to burns, trauma or interference. The async on/off softkey button is
pressed and aysnc mode is displayed. No PPM or electrical capture will be
seen on the screen. Mechanical capture will only be proven by palpating a
pulse if one is achieved
