5.17.11.hpv in males
Researchers in Austria examined foreskin tissue from 133 males who underwent circumcision and found:
1) Low-risk HPV genotypes were present in 18.8% of samples and high-risk HPV in 9.77% of samples.
2) The presence of subclinical HPV in males suggests vaccinating boys prior to puberty could help prevent HPV transmission through sexual contact.
3) HPV vaccination for girls is accepted medical practice for preventing HPV infection and cervical cancer, but this study provides novel evidence that vaccinating boys too may help reduce HPV spread.

This document discusses cervical carcinoma and prospects for primary prevention. It summarizes that cervical cancer is the second most common cancer in women worldwide, caused over 99% of the time by human papillomavirus (HPV) infection. Screening methods like Pap smears have been effective in developed countries but are too expensive for low-resource areas. The document explores more affordable options like visual inspection with acetic acid (VIA) and prospects for an HPV vaccination to help developing countries prevent cervical cancer.
Human Papiiloma Virus
Human papilloma virus (HPV) is a DNA virus that can cause warts and is linked to certain cancers. There are over 100 types of HPV that can infect humans. HPV types 16 and 18 are highly carcinogenic and associated with cervical and other cancers. HPV is transmitted through skin-to-skin contact, usually during sexual activity. While most HPV infections do not cause symptoms and resolve on their own, some types can cause genital warts or warts in the throat. The HPV E6 and E7 proteins contribute to cancer development by degrading tumor suppressor proteins. Vaccines targeting the HPV L1 protein show promise in preventing HPV infection and reducing cancer rates.

1. Cervical cancer is a major health issue in India, accounting for 23% of new cervical cancer cases and 25% of cervical cancer deaths worldwide.
2. Human papillomavirus (HPV) infection causes cervical cancer, with vaccination providing 98-100% efficacy against HPV types.
3. Screening and vaccination can help prevent cervical cancer, but coverage in India remains low due to cost and lack of national programs.

This document summarizes two recent discoveries related to DNA: 1) Researchers discovered 22 new types of HPV virus in "virus-negative" genital wart samples through DNA sequencing. This shows DNA sequencing can identify unknown virus types and improve diagnoses. 2) Scientists discovered the NEIL1 enzyme, which marks errors in single-strand DNA before replication to stop errors from persisting. Understanding these DNA repair and replication mechanisms could help develop new cancer and genetic disease treatments. The student believes both discoveries can expand medical knowledge and help diagnose and treat various diseases.
Molecular Biology on Cancer and HIV
The documents discuss new combination therapies to treat breast cancer and HIV. A Boston study found a combination of epigenetic and protease inhibitor drugs effectively inhibited growth and increased death of breast cancer cell lines. Scientists also discovered a safer method of using zinc finger nuclease proteins to disrupt specific genes as an alternative to experimental HIV gene therapy, reducing risks of viral incorporation into cellular DNA or excessive off-target DNA cuts. The new therapies offer hope for developing more effective and safer treatments for breast cancer and HIV.

Cervical cancer
Cervical cancer is the fourth most common cancer in women globally, with over 500,000 new cases occurring in 2012. Certain strains of human papillomavirus (HPV), such as HPV-16 and HPV-18, are the primary cause of cervical cancer. HPV works by degrading tumor suppressor proteins and disrupting cell cycle regulation through its E6 and E7 proteins. Regular Pap smear screening can detect pre-cancerous lesions and reduce cervical cancer deaths by up to 80% by allowing for early treatment. Risk factors for cervical cancer include early age of first sexual intercourse, multiple sexual partners, low socioeconomic status, smoking, and HIV/AIDS.
Tumour markers
Tumor markers are substances produced by tumor cells or the body's response to tumors that can be detected in blood, urine, or tissue. They can be used to screen for cancers, help diagnose cancer when the primary site is unknown, stage cancers, determine prognosis, and monitor treatment effectiveness. The most widely accepted tumor markers are prostate-specific antigen for prostate cancer screening and alpha-fetoprotein plus ultrasound for screening for hepatocellular carcinoma in endemic areas. Elevated levels of markers like gastrin and insulin are diagnostic for certain neuroendocrine tumors.
Poster Outline (1)
The document summarizes a study examining whether the titer of autoantibodies against SELENBP1 changes as hens develop ovarian cancer tumors. The study found no significant difference in the percent change of optical density (OD) values between hens that developed ovarian cancer tumors and normal hens. While the hypothesis was that antibody titer would decrease as tumors developed, the titer remained fairly constant. However, other studies from Rush University suggest SELENBP1 autoantibodies may still have potential as an ovarian cancer biomarker. Further experiments are needed to draw definitive conclusions.

This document discusses risk factors for breast cancer. It notes that family history of breast cancer, personal history of breast cancer, genetic alterations like mutations in BRCA1 and BRCA2 genes, early age of first menstruation, late age of first childbirth or fewer children, hormone replacement therapy, obesity after menopause, and alcohol consumption can increase a woman's risk. It also provides details on BRCA1 and BRCA2 genes which normally help repair DNA damage but mutations can increase cancer risk.

This document discusses the issue of cancer overdiagnosis and overtreatment. It notes that improved screening technologies are detecting more cancers, but not all of these cancers pose a health risk or need treatment. Some experts argue for changing how indolent or slow-growing cancers are defined and classified to reduce overtreatment. They propose distinguishing cancers that will likely progress from those that will not, in order to tailor treatment approaches and avoid unnecessary procedures. Large datasets on cancer genetics and behaviors are needed to better stratify and predict cancer risks and outcomes.

CERVICAL CANCER & ITS PREVENTION
Welcoming remarks by Dr Osborne E Nyandiva on Symposium: Cervical cancer and its prevention
Co-Presenter Dr Giama. We are happy to present to you this very crucial discussion on Cancer.
Cervical cancer is a type of cancer that develops in a woman's cervix (the entrance to the womb from the vagina).
Cancer of the cervix often has no symptoms in its early stages. If you do have symptoms, the most common is unusual vaginal bleeding, which can occur after sex, in between periods or after the menopause.

Early Gender Blood Test have the power to unmask the hidden truth of cancer. Early Gender Blood Tests possess the remarkable ability to unveil the concealed secrets of cancer, shedding light on this enigmatic disease and potentially revolutionizing our understanding of it. These innovative tests have the potential to reveal vital insights that may lead to more effective detection and treatment strategies, offering hope to those affected by this formidable adversary.
Hpv Cause For Disease
HPV is one of the most common viruses transmitted through sexual activity. It can cause cervical cancer by inserting its DNA into host cells. For decades, the cause of cervical cancer was unknown, but research in the 1930s first linked viruses to wart growth in rabbits. Later work in the 1990s definitively confirmed HPV as the necessary cause of cervical cancer through case-control and cohort studies showing those with HPV had a much higher risk. Specific HPV strains like types 16 and 18 are strongly associated with cervical cancer development.

Karyometry Identifies a Distinguishing Fallopian Tube Epithelium Phenotype in...ANALYTICAL AND QUANTITATIVE CYTOPATHOLOGY AND HISTOPATHOLOGY
This study aimed to use karyometry to detect nuclear abnormalities in fallopian tube epithelium from women at high risk for ovarian cancer compared to low risk women. Karyometry involves high-resolution imaging and quantitative analysis of nuclear features too small to be seen by the human eye. The study found distinct deviations in nuclear features and signatures in fallopian tubes from high risk women carrying BRCA1/2 alterations compared to normal risk women. Specifically, measures of pixel optical density heterogeneity and very dark stained pixels showed a statistically significant shift, identifying an abnormal morphometric phenotype in high risk women. The results suggest karyometry may help detect early changes and improve ovarian cancer screening.Cervical cancer pp
Screening modalities like the Pap test and HPV test can help detect abnormal or precancerous cervical cells. The Pap test screens for cell changes and is recommended starting at age 21 and every 3 years. The HPV test screens specifically for the human papillomavirus, which can cause cell changes. For women over 30, both tests may be used. Certain groups like those without insurance can access free screening services. While screening is important, both false positives and false negatives can occur with the Pap test. Multiple organizations provide guidelines around cervical cancer screening.

Treatment options depend on age and test results but aim to remove visible warts or abnormal cells.
Pni and nmsc
Incidental perineural invasion (PNI) is identified on histopathology in clinically asymptomatic patients. Clinical PNI presents with sensory or motor changes or radiographic evidence of PNI. Management of PNI requires diagnosis, evaluation of extent, consideration of other high-risk tumor features, and treatment. For incidental PNI in basal cell carcinoma (BCC), Mohs micrographic surgery (MMS) or standard surgery with adjuvant radiation therapy provide similar cure rates of around 90% at 5 years. For squamous cell carcinoma (SCC) with incidental PNI, features such as nerve size, extent of invasion, and presence of other high-risk features determine whether adjuvant radiation therapy is recommended after MMS. Clinical P
Cervical Cancer 101
Cervical cancer is caused by persistent HPV infection in the cervix. HPV is very common and spread through skin to skin genital contact. While most HPV infections go away on their own, persistent infections can lead to cervical cancer if not addressed. Regular Pap screening can detect pre-cancerous cells early so they can be treated before they develop into cancer. Prevention strategies include HPV vaccination, smoking cessation, condom use, and limiting sexual partners. Abnormal Pap results may require further tests like colposcopy or biopsies. Early cervical cancer is highly curable, especially when caught through regular screening.

Screening modalities like the Pap test and HPV test can help detect abnormal cervical cells that could become cervical cancer if left untreated. The Pap test screens for cell changes and is recommended starting at age 21 and every 3 years. The HPV test screens specifically for the human papillomavirus that can cause cell changes, and is often used along with the Pap test for women over 30. Certain groups like low-income women may be able to access free screening services. While screening helps detect cervical cancer early, tests can sometimes provide false positives or negatives, so guidelines recommend less frequent screening to avoid unnecessary procedures. Factors like multiple sex partners or smoking can increase cervical cancer risk for some populations.
Biology
There have been a few reported cases where individuals were infected with HIV but then eliminated the virus from their body after a year or two with no detectable virus. Some experts believe these individuals may have succeeded in curing their HIV infection. Certain genes may provide some people with natural protection against HIV. By studying these genes, researchers hope to find ways to protect others. Some individuals exposed to HIV show signs of immune response to the virus but do not become infected, suggesting their immune system eliminated the virus upon exposure. Many people may have the ability to destroy a limited number of HIV particles, preventing infection from small exposures.
Laboratory diagnosis of cancer
Laboratory diagnosis of cancer involves cytology, histopathology, and other techniques. Fine needle aspiration cytology (FNAC) is a simple, rapid, and economical technique to obtain cells for cancer diagnosis. It has high accuracy but loses tissue architecture. Histopathology examines diseased tissue microscopically and macroscopically. Cancer is graded based on cell differentiation and staged based on tumor size, lymph node involvement, and metastasis. Immunohistochemistry aids in cancer classification and detection of molecules with prognostic value.

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
