An introduction to virology
This document provides an overview of virology and viral replication. It begins with an outline of topics to be covered, including the structure and classification of viruses, basic virology, and clinical virology. It then discusses viral structure, noting there are five basic types. Viral replication is summarized in seven steps: adsorption, entry, uncoating, transcription, synthesis of viral components, assembly, and release. Control methods involve knowledge of reservoirs, transmission, inactivation methods, vaccines, antiviral drugs, and drug resistance. Emerging viral diseases and some examples are also mentioned.
Parvo virus
Parvoviruses are the smallest DNA viruses, including human parvovirus B19. B19 is pathogenic in humans, infecting erythroid progenitor cells and causing fifth disease in children characterized by a rash. It can also cause aplastic crisis, hydrops fetalis in fetuses, and chronic anemia in immunocompromised patients. Diagnosis involves detecting IgG and IgM antibodies by ELISA or PCR to detect the virus. There is no treatment, though a vaccine is in clinical trials.

HPV can cause genital warts and cancers, especially cervical cancer. It discusses HPV types, risk factors, progression of cervical disease, and the HPV vaccine Gardasil. Gardasil was found to be highly effective against HPV types 16 and 18 in clinical trials, providing nearly 100% efficacy against precancerous cervical lesions caused by these high-risk HPV types.
Epstein-Barr Virus
The Epstein-Barr virus (EBV) is commonly associated with mononucleosis and is transmitted through saliva. EBV infects 95% of adults worldwide and has been linked to illnesses like mononucleosis in adolescents and cancers like Burkitt's lymphoma and nasopharyngeal carcinoma. EBV is able to immortalize cells and exists in a lifelong latent infection in humans. While most EBV infections are asymptomatic, infection in adolescents can cause mononucleosis with symptoms like fever, lymphadenopathy, and fatigue that typically resolves on its own. EBV reactivation in immunocompromised individuals can also sometimes lead to lymphoproliferative diseases or lymphomas.
Parvoviruses
Parvoviruses are small, non-enveloped viruses with a single-stranded DNA genome. They are significant pathogens in veterinary sciences and are associated with reproductive failure in various host species. The human parvovirus B19 is the only known parvovirus that is pathogenic to humans, infecting and destroying erythrocyte precursor cells. It causes a range of symptoms from none to a mild rash illness called fifth disease. While usually not serious in children, it can cause joint pain in adults and pose a risk to pregnant women.

There are two HPV vaccines, Cervarix and Gardasil, that help protect against types of HPV that can cause health problems including cervical cancer. Cervarix helps prevent cervical cancer and precancers caused by HPV types 16 and 18. Gardasil helps protect against 4 types of HPV that cause about 90% of genital warts cases and 75% of cervical cancer cases. Both vaccines are given as a series of shots over 6 months but do not prevent all HPV types or treat existing HPV infections or cancers. Common side effects include pain, swelling and fever at the injection site.
Recent updates in hpv vaccines
This document discusses cervical cancer and HPV in India. It notes that India accounts for 27% of new cervical cancer cases and deaths worldwide despite having only 16% of the global population. It is estimated that over 365 women will die from cervical cancer daily in India by 2025. HPV is the main cause of cervical cancer and certain HPV types are also associated with other cancers. The document discusses HPV vaccines as the primary prevention for HPV-related diseases and recommends routine vaccination of girls aged 9-12 years along with catch-up vaccination up to age 26. It provides details on the available HPV vaccines and their efficacy, safety and recommended dosage schedules.
HPV
O HPV é um vírus transmitido sexualmente que pode causar verrugas genitais e aumentar o risco de câncer do colo do útero. Existem vários tipos de HPV, sendo os do tipo 16 e 18 responsáveis por mais de 80% dos casos de câncer do colo do útero. A prevenção inclui vacinação e exames periódicos, enquanto o tratamento depende do tipo e local da lesão.
Type-specific detection of human papillomaviruses in a followed-up French cohort
This study used the Roche line blot assay to genotype HPV in cervical samples from 59 French women over time. It found that persistent infection with HPV-16 was most strongly associated with progression to high-grade lesions. While double or multiple infections were common, they were not clearly linked to increased risk of disease progression. The results confirm the role of persistent HPV-16 infection in cervical disease and suggest that co-infection status alone may not be a strong prognostic factor. Further studies with this assay could expand understanding of HPV epidemiology and disease.
Vaginal Thrush
The document discusses thrush and vaginitis. Common symptoms include itching, discharge, burning during urination, discomfort during sex, and rash. Symptoms are caused by infections like thrush, bacterial vaginosis, and trichomoniasis that lead to vaginal inflammation. Other causes can include steroid creams, douching, and contraceptives. Many women misdiagnose themselves and do not seek proper testing and treatment, promoting recurrent infections and resistance. The key is to obtain an accurate diagnosis through a home test or clinic before proceeding with treatment.
Human papillomavirus
Human Papillomarius is caused by human papillomavirus (HPV), which are viruses that infect the skin and mucous membranes. Some HPV infections cause no symptoms, while others cause warts on the skin or genitals that in some cases can develop into cancer. HPV is transmitted through anal, oral, or vaginal sex with an infected person. Prevention methods include abstaining from sex or using protection. Treatment involves prescription medications to remove visible warts.
Atypical facial pain
Atypical facial pain describes a type of chronic dull pain that may affect one or both sides of the face and is not associated with nerve distributions. It has no clear underlying cause. Management involves eliminating potential systemic or local causes, counseling, and cognitive behavioral therapy or antidepressant therapy to address pain beliefs and anxiety. Cognitive behavioral therapy aims to help patients restructure thoughts about their pain and change avoidance behaviors through relaxation, distraction, and activity.
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.
Mukokutan kandidiasis
Candidiasis is a fungal infection caused by Candida species, usually Candida albicans. It can affect the mucous membranes, skin, nails, GI tract, and organs systemically. Candidiasis is found worldwide and can affect people of all ages with predisposing factors like chronic diseases, pregnancy, antibiotics, and high temperature/humidity. Symptoms vary depending on the infected site, such as white patches in the mouth (oral thrush), skin cracks at the mouth corners (perleche), white vaginal discharge (vulvovaginitis), penile plaques (balanitis), and lesions in immunocompromised patients (chronic mucocutaneous candidiasis).
Natural history and pathogenesis of hpv
The document summarizes the natural history and pathogenesis of HPV. It discusses the worldwide burden of cervical cancer, phylogenetic classification of HPV, and the viral lifecycle within host cells. Persistent infection with high-risk HPV types is required for progression from normal cervical epithelium to pre-cancerous lesions and eventually invasive cervical cancer, with the contribution of additional genetic mutations and external cofactors over long periods of time.

HPV is a double stranded DNA virus that can cause warts and cancers. It is categorized into low-risk HPVs that cause warts and high-risk HPVs linked to cancers like cervical cancer. HPV is commonly transmitted sexually and globally infects about 11.7% of people. Persistent infection with high-risk HPV types can lead to cancer through viral proteins that inactivate tumor suppressor genes. While most HPV infections clear naturally, vaccination is recommended to prevent infection and cancer.
HPV and Cervical Cancer
Cervical cancer is a major health problem, but HPV vaccination and screening can reduce rates. HPV is transmitted sexually and can cause cervical cancer. The vaccine protects against high-risk HPV types 16 and 18, which cause most cancers. Northern Ireland has high HPV vaccination rates. While the vaccine reduces cancer risk, screening is still needed since the vaccine does not protect against all HPV types and cannot help women already infected. In the future, screening may shift to HPV testing as prevalence decreases due to vaccination.
56.0 Human Pappiloma.ppt
Human papillomavirus (HPV) is a virus that can cause warts or lead to cancer. There are over 100 types of HPV, with some causing common warts and others linked to cancers like cervical cancer. HPV is very common and spread through skin-to-skin contact, most often during sex. Persistent infection with high-risk HPV types can cause precancerous lesions and cancers over many years if left untreated. Diagnosis involves clinical exams, testing for HPV DNA, and biopsies. Treatment options depend on the infection but may include cryotherapy, medications, or surgery. Vaccines for HPV types 16 and 18 can prevent most cervical cancers if given before exposure to the virus.
Hpv vaccine
HPV (human papillomavirus) is extremely common, with 80% of sexually active people contracting a strain at some point. It causes various cancers and genital warts. While most HPV infections clear on their own, persistent infections increase cancer risk. Vaccines target high-risk HPV strains responsible for 70% of cervical cancers. They provide sustained, high-level immunity for at least 4.5 years with minimal side effects. Screening and vaccination can significantly reduce HPV-related cancers globally.

The document discusses two syndromes - complex regional pain syndrome (CRPS) and postural orthostatic tachycardia syndrome (POTS) - that some young women reported developing after receiving HPV vaccines. The European Medicines Agency reviewed the evidence and found no causal relationship between the HPV vaccines and the syndromes. They determined the rates of the syndromes were not significantly different between vaccinated groups and the general population. The conclusion was that CRPS and POTS are not linked to HPV vaccinations, and that all HPV vaccines remain safe and effective.

All about the Human Papillomavirus
Human papillomavirus (HPV) is the most common sexually transmitted infection. Most HPV infections are asymptomatic but persistent infections can cause various cancers like cervical cancer. HPV is transmitted through direct skin-to-skin contact, usually during sexual activity. While vaccination can prevent HPV infection, screening is still important for cervical cancer prevention as HPV vaccines do not protect against all cancer-causing HPV types. Current guidelines recommend cervical cancer screening every 3-5 years depending on age and test type for average-risk individuals.
HPV
1) The document discusses HPV vaccines for adolescents, recommending vaccination at ages 11-12 to protect against cancers caused by HPV. It describes three HPV vaccines that protect against different HPV types.
2) HPV is very common and can cause various cancers as well as genital warts. While most infections resolve, persistent infections can lead to cancer.
3) HPV vaccines have been found to be very safe and effective in clinical trials and in decreasing HPV-related infections and diseases in vaccinated populations.
Hpv
The document provides information on HPV vaccines for clinicians. It recommends HPV vaccination for girls and boys at ages 11-12 to protect against cancers caused by HPV. It discusses that HPV is a common virus that can cause cancers, and three HPV vaccines (bivalent, quadrivalent, 9-valent) protect against types of HPV that cause cancers. It provides safety and effectiveness information about the vaccines and dosing schedules.
Human papillomavirus infection and cervical cancer.
Cervical cancer is caused by sexually acquired infections with certain types of HPV. Two HPV types (16 and 18) cause 70% of cervical cancers and pre-cancerous cervical lesions. There is also evidence linking HPV with cancers of the anus, vulva, vagina, penis, and oropharynx
Hpv and early carcinoma cervix
Cervical cancer is the second most common cancer in women worldwide and is caused primarily by certain strains of the human papillomavirus (HPV). HPV is very common and spreads through sexual contact. While most HPV infections cause no symptoms and go away on their own, persistent infections with high-risk HPV types can cause normal cervical cells to become precancerous and develop into cancer over time if not treated. Screening for HPV and abnormal cervical cells through Pap tests and HPV tests is important for early detection and prevention of cervical cancer.
Cervix
This document summarizes the anatomy, histology, and pathologies of the uterine cervix. It discusses the normal cervix epithelium and how cervical inflammation and infections can cause conditions like cervicitis. Precancerous lesions like cervical intraepithelial neoplasia are often caused by human papillomavirus infection and can progress to invasive cervical cancer if left undetected and untreated. Screening methods like the Pap test aim to detect these early lesions to prevent cervical cancer.
Cervical Cancer
Cervical Cancer is common worldwide , ranking 3rd among all malignancies for women.
Second leading cause of cancer death.
Most of these cancers stem from infection with the Human Pappiloma Virus (HPV).

Cancer cervix screening
This document discusses cervical cancer screening. It begins with the epidemiology of cervical cancer, noting it is the 3rd most common gynecologic cancer in the US but 2nd most common in countries without screening. Risk factors include early sexual activity, multiple partners, HPV infection, and low socioeconomic status. Screening with Pap tests has reduced cervical cancer rates by 70% in the US. The document then discusses screening guidelines, techniques for Pap tests, interpreting results, HPV vaccination, and screening special populations like immunocompromised women.
CERVICAL CANCER presentation for the clinic
Cervical cancer is a leading cause of cancer deaths in women worldwide. It is caused by human papillomavirus (HPV) infection and can be prevented through HPV vaccination and screening. Early detection through tests like visual inspection with acetic acid helps detect pre-cancerous lesions early on so they can be treated before the cancer develops further. Treatment depends on the stage of cancer and may involve surgery, radiation therapy, or chemotherapy, with the goal of curing early-stage cancer or palliatively treating advanced stages.

Mandible fx-slides-040526
Mandible fractures are common facial injuries that can be treated with either closed or open reduction methods depending on the severity and location of the fracture. Closed reduction using maxillomandibular fixation is preferred for non-displaced or favorable fractures in children and adults. Open reduction with rigid internal fixation using plates, screws, or external fixation is used for displaced, unfavorable, or comminuted fractures. Condylar fractures may be treated with closed reduction for children but often require open reduction in adults due to higher risk of complications from malunion. Immediate postoperative mobilization after open reduction has been shown to have similar outcomes to traditional maxillomandibular fixation.

Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.#cALL# #gIRLS# In Dehradun ꧁❤8107221448❤꧂#cALL# #gIRLS# Service In Dehradun W...

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).
Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
