Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

Protection from a Single Dose of HPV Vaccine A major public health impact from IARC studies of vaccine efficacy.
While epidemiological data for type 1 diabetes (T1D) in low/middle-income countries, and particularly low-income countries (LICs) including Liberia is lacking, prevalence in LICs is thought to be increasing. T1D care in LICs is often impacted by challenges in diagnosis and management. These challeng...es, including misdiagnosis and access to insulin, can affect T1D outcomes and frequency of severe complications. Despite the severe nature of T1D and growing burden in subSaharan Africa, little is currently known about the impact of T1D on patients and caregivers in the region. Methods We conducted a qualitative study consisting of interviews with patients with T1D, caregivers, providers, civil society members and a policy-maker in Liberia to better understand the psychosocial and economic impact of living with T1D, knowledge of T1D and selfmanagement, and barriers and facilitators for accessing T1D care.

Diabetes is a major public health problem in the Americas and worldwide, demanding special attention and integrated response. It is estimated that more than 62 million adults are living with diabetes in the Americas. The projections show that diabetes prevalence will continue to increase to at least... 2025. Its steady rise has been mainly due to the high prevalence of risk factors, especially overweight/obesity and physical inactivity.

One of the main aims of the WHO Global Initiative for Childhood Cancer and the CureAll Americas framework is to strengthen centers of excellence and promote the training of the health workforce, especially pediatric oncology nurses, specialized in nursing care for children and adolescents with cance...r and their families. These health personnel provide compassionate, non traumatic, complex, continuous, ethical, conscious patient- and family-centered care in order to meet the physical, emotional, psychosocial, and cultural needs of the people involved. This publication is aimed at health administration teams, hospital management teams, and professional pediatric oncology nursing groups. Its objective is to identify, systematize, and consolidate available evidence on the scope of pediatric oncology nursing practice in Latin America and the Caribbean based on core competencies, in order to incorporate them into clinical practice, teaching, and research. The preparation process included a systematic review aimed at finding the best evidence on this subject. Patient- and family centered care and the conceptual model of competencies for teenagers and young adults with cancer, developed by the Teenage Cancer Trust with the support of the Royal College of Nursing, were the theoretical foundations supporting the systematization of recommendations.

The article explores the underlying factors influencing unhealthy diets and sedentary lifestyles among adolescents in Kilifi County, Kenya. Using a qualitative approach, the study involved interviews and focus group discussions with adolescents, stakeholders, and young adults. Key findings include a... preference for unhealthy, carbohydrate-rich, and sugary foods over traditional and nutritious options, exacerbated by factors like low socioeconomic status, urbanization, and poor farming practices.
Sedentary behavior, such as gambling and extensive technology use, was prevalent, often replacing physical activity. Protective factors like school attendance, community-based services, and parental engagement were identified as mitigating risks. The study highlights the importance of ecological intervention strategies targeting intrapersonal, interpersonal, and community factors to address unhealthy behaviors and promote better health outcomes in adolescents.

Introduction Pharmacovigilance (PV) systems to monitor drug and vaccine safety are often inadequate in sub-Saharan
Africa. In Malawi, a PV enhancement initiative was introduced to address major barriers to PV.
Objective The objective of this initiative was to improve reporting of adverse events (A...Es) by strengthening passive safety
surveillance via PV training and mentoring of local PV stakeholders and healthcare providers (HCPs) at their own healthcare
facilities (HCFs).
Methods An 18-month PV training and mentoring programme was implemented in collaboration with national stakeholders,
and in partnership with the Ministry of Health, GSK and PATH. Two-day training was provided to Expanded Programme on
Immunisation coordinators, identified as responsible for AE reporting, and four National Regulatory Authority representa-
tives. Abridged PV training and mentoring were provided regularly to HCPs. Support was given in upgrading the national
PV system. Key performance indicators included the number of AEs reported, transmission of AE forms, completeness of
reports, serious AEs reported and timeliness of recording into VigiFlow.
Results In 18 months, 443 HCPs at 61 HCFs were trained. The number of reported AEs increased from 22 (January 2000 to
October 2016) to 228 (November 2016 to May 2018), enabling Malawi to become a member of the World Health Organization
Programme for International Drug Monitoring. Most (98%) AE report forms contained mandatory information on reporter,
event, patient and product, but under 1% were transmitted to the national PV office within 48 h.
Conclusion Regular PV training and mentoring of HCPs were effective in enhancing passive safety surveillance in Malawi,
but the transmission of reports to the national PV centre requires further improvement.

Medical devices are used for the prevention, diagnosis and treatment of illness and diseases and for rehabilitation. WHO developed guidance on medical device donation in 2011, which has been now reviewed, with new evidence, new references on considerations for medical device solicitation and provisi...on, risks associated with inappropriate donations, the responsibilities of donors and recipient, and the steps they should follow before, during and after a donation. It includes three sections: description of major problems that may be faced during the donation process, listing of best practices for donors and recipients and addressing situations requiring special attention. It also has three annexes for further reading: the criteria for the acceptability of a donation, literature review on donations of medical devices between 2010 and 2023 and a flyer. This document is intended to improve the quality of medical devices donations, including medical equipment, single-use medical devices and in-vitro diagnostics, to provide maximum benefit to all stakeholders. The considerations can be used to develop institutional or national policies and regulations for medical devices donations. This document is intended for use by any organization, expert or practitioner involved in the donation, procurement, management of medical devices, including health workers, biomedical engineers, health managers, policymakers, donors, nongovernmental organizations and academic institutions.
