ABSTRACT
Pharmaceutical supply chains have become increasingly complex due to the shift of manufacturing and critical operations to Asia. U.S. pharmaceutical dependency on foreign sole-source production of essential materials imposes vulnerability affecting the entire industry and national health systems from interruption by exposure to natural events and man-made threats, both accidental and criminal as well as political. Sector vulnerabilities stem from complex regulatory landscape, difficulties for enforcement of quality standards at foreign facilities, single-source supply chain resulting from limited sourcing options, increasing shipping distance exposure to both natural events and complicated by maritime chokepoints. Periodic and chronic shortages of many essential products across therapeutic categories have been significant for more than a decade. The Covid-19 crisis aggravated some of these long-standing issues and made the systemic vulnerabilities publicly evident. The combination of limited capacity to exercise control over essential commodities, the long-term trend of outsourcing, with the politicization of business relationships causes the entire pharmaceutical industrial sector to be internationally dependent, creating numerous potentials for systemic failure.
Why is the orphan drug area receiving increasing attention? In this presentation you will find the primary reasons explained.

Availability of essential medicines in Hungary (2017)Arete-Zoe, LLC
This report analyzes availability of essential medicines as defined in the World Health Organization (WHO) Essential List Medicines (Report of the WHO Expert Committee) in Hungary. The WHO list of essential medicines contains most effective and safe medicines needed to meet the most important needs in health systems and is frequently used by countries to create their own national lists. Without these drugs, some conditions will not be able to receive optimal therapy. Availability gap represents serious public health concern. Expert Committee of the World Health Organization selects Essential Medicines Lists in accordance with approved procedures. The Committee evaluates the scientific evidence on the basis of the comparative effectiveness, safety and cost-effectiveness of the medicines.

Pharmacovigilance: Regulators’ Perspective on Proactive Risk Management, Chal...Bhaswat Chakraborty
The prescription drug sales have been growing globally at a rate of 12-20%, which is lucrative by any standards, especially when top companies’ total sales are approaching 25-40 billion USD a year. Such market forces create tremendous pressure on one side on the drug sponsors to launch their product as early as possible, and on the other hand on the significantly regulators to decide on the product safety for approval with a tremendous time constraint. In such a scenario, drug regulatory authorities in US, Europe and elsewhere have renewed their mandate to fortify the “safety” regulations so that the drugs released to the market are highly safe and effective. The FDA Amendment Act, 2007 (FDAAA) have now authorized FDA to significantly increase the user fees for safety initiatives and evaluations. The FDA initiatives include its authority to ask from a drug sponsor a Risk and Evaluation Mitigation Strategy (REMS) with a detailed risk minimization action plan. FDA can now require the sponsor to develop a comprehensive safety surveillance system as well. For each new drug, FDA will now also establish an internal committee for a safe use of this drug in pediatric population. Similar approaches and authorities have also been given to European drug regulatory agencies.
This presentation will take you through the current proactive risk management approaches used or proposed by the prominent regulatory agencies for both pre- and post- market safety surveillance of new drug and new drug products. It will also discuss the challenges and collaborative efforts of both regulators and industry to work with a multidisciplinary safety management system to identify and assess the risk signals as early as possible in drug development process. Further it will discuss the reporting and evaluation of this data such that it helps pre-market approval of the safest possible product and a transparent post-market surveillance plan.

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.
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!
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.

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.
9. Vioxx safety data manipulated In Sep 2004 Merck publicly announced its voluntary withdrawal of the drug vioxx a 2.5 billion $ seller from the market worldwide. Drug companies has been found to have suppressed and manipulated certain critical data that misled the regulatory body — U.S.FDA.
