The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased risk for heart failure (HF). Moreover, HF patients wit...h DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.

The report showed commitments made three decades ago to protect the rights of children remain unfulfilled for millions. Violence still affects countless children. Discrimination based on age, gender, disability, sexual orientation and religion harms children worldwide.
The UN Convention on the Ri...ghts of the Child is the most widely ratified international human rights treaty in history. It has prompted substantial investment in children’s health, education and safety and the adoption of laws and policies that recognise the rights of children, particularly in areas where they are vulnerable, including labour exploitation, corporal punishment, alternative care and forced and early marriage.

Loss and damage is an urgent concern, driven by the increasingly harmful effects of climate change. Communities are experiencing new types and forms of climate impact, of higher frequency and intensity, which they are not equipped to handle. These impacts compel vulnerable communities to migrate to ...find alternative livelihoods and ways to survive. But migration generates grave socioeconomic consequences. Through case study analysis from 12 regions in Asia, Africa and the Pacific, this paper explores how climate change-induced migration is creating physical health, mental health and wellbeing issues — both for migrants and the families they leave behind. It then provides recommendations to policymakers on how to strengthen policy, planning and response frameworks to support communities manage health and wellbeing risks created by climate impacts.

The war in Gaza has resulted in many hundreds of spinal cord injuries (SCI), which will have a devastating impact on those injured and their families for the rest of their lives.
The optimal management of SCI requires effective pre-hospital care, early specialized imaging (using CT or MRI) and in... many cases early surgical interventions by a highly specialised neurosurgical team. Surgery requires many hours of use of a sterile operating room environment and supportive critical care capacity, as well as intensive post-operative care – none of which is currently possible due to the ongoing war, destruction, and disruption of health services in Gaza.
An alternative to surgery is conservative management – this requires intensive nursing care under full spinal precautions for many weeks in order to allow for bone and soft tissue healing and prevent further injury to the spinal cord. The patient is unable to move independently in bed during this period. Those caring for the patient need to be able to safely reposition them every 2 hours, and manage all their bowel and bladder care needs. The patient needs good nutrition and hydration at all times, as well as access to medication to support bowel care, manage pain (including neuropathic pain). A caregiver must remain with the patient to be trained to provide ongoing care and assist with daily care.

The article "An Official ATS Workshop Report: Issues in Screening for Asthma in Children" summarizes discussions from a workshop organized by the American Thoracic Society (ATS) on the challenges of asthma screening in children. The report reviews the effectiveness of population-based asthma screeni...ng programs, highlights the limitations of current methods, and discusses case detection as an alternative. It assesses asthma's impact as a public health issue, explores the feasibility of screening tests, and examines the economic and practical challenges. The workshop concludes that broad population-based screening may not be justified without better evidence and targeted efforts to improve follow-up care and treatment access.

Scientists have known for more than half a century that patients could develop resistance to the drugs used to treat them. Alexander Fleming, who is credited with creating the first antibiotic, penicillin, in 1928, cautioned of the impending crisis while accepting his Nobel prize in 1945: “There ...is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant.” Since then antibiotics have proved one of the most effective interventions in human medicine. Sadly, the overuse and misuse of this precious resource have brought us to a global crisis of antimicrobial resistance (AMR). To address this crisis nearly seven decades after Fleming’s lecture the first UN general assembly meeting on drug resistance bacteria was convened in September 2017.

O número de Estados Membros da União Africana a reportarem
casos do COVID-19 está a aumentar e existe uma probabilidade de transmissão comunitária. A OMS modificou recentemente a definição
de caso suspeito do COVID-19, de modo a incluir infecção respiratória aguda grave... e aconselha a testagem de todos os casos de doença respiratória aguda grave (SARI).1 Contudo, muitos Estados Membros ainda não começaram a implementar estas alterações, pois ainda estão a concentrar os esforços na vigilância de indivíduos com histórico de viagem para uma área com transmissão local do COVID-19. Isto significa que os doentes com sintomas semelhantes, mas sem contacto aparente, podem não ser investigados.

The speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

This paper examines determinants of one aspect of sexual behaviour – coital frequency – among 2188 married women in the Central African Re...public using a secondary analysis of data from the Demographic and Health Survey of 1994–95. Female genital cutting (or circumcision) is practised in the Central African Republic and self-reported circumcision status was included in the questionnaire enabling it to be examined as a possible determinant of coital frequency. Multiple logistic regression was used to find a subset of factors independently associated with coital frequency.
Decreased coital frequency was found in those who had longer duration of marriage, those who were not the most recent wife in a polygamous marriage and those who had more surviving children. Coital frequency was higher in more educated women and those not contracepting because they wanted to get pregnant. After adjusting for confounders no association between
female genital cutting and coital frequency was found. The extent to which women can control coital frequency in this culture is not known and fertility desires may override any negative effects of circumcision on sexual pleasure.
It was therefore not possible to draw conclusions about how female genital cutting affects a woman’s desire for sexual intercourse and consequently there is a need to develop research methods further to investigate this question.

The Global Health Expenditure Report delves into the intricate landscape of global economies and health systems. This year, it focuses on health spending in 2022, the third year of the COVID-19 pandemic. It shows how countries around the world responded to the health and economic shocks of the pande...mic from a financial perspective. It also considers what the future may hold as countries emerge from the pandemic. Although it is still too early to gauge whether the COVID-19 pandemic has altered long-term trends in health spending, spending appears to have peaked and is now at or below its long-term rising trend in most country income groups. Additionally, to mark the 25th anniversary of the World Health Organization’s (WHO) Health Expenditure Tracking Program, the report reviews the program’s achievements and envisions a path forward. As the program’s lead technical agency, WHO is committed to working closely with partners to support countries in tracking health spending and sustaining the Global Health Expenditure Database and the Global Health Expenditure Report as global public goods.

Most foreign aid comes in one of two forms: either we pay a person or an institution today in exchange for delivering some beneficial activity in the future, or we observe something bad happen to them and then give them support to recover from it. This kind of aid is simple to design and deliver,
b...ut in the former case has limits in how sharply it incentivizes success and effort from a range of actors and in the latter case leads to the inefficient and undignified “begging bowl” approach to humanitarian financing. In what follows, I identify a broad family of alternative approaches, which
can loosely be grouped together as “contractually contingent financing,” and explain why they are still relatively underused.

Acute Radiation Syndrome (ARS) (sometimes known as radiation
toxicity or radiation sickness) is an acute illness caused by
irradiation of the entire body (or most of the body) by a high dose
of penetrating radiation in a very short period of time (usually ... a
matter of minutes). The major cause of this syndrome is depletion
of immature parenchymal stem cells in specific tissues. Examples of
people who suffered from ARS are the survivors of the Hiroshima
and Nagasaki atomic bombs, the firefighters that first responded
after the Chernobyl Nuclear Power Plant event in 1986, and some
unintentional exposures to sterilization irradiators.

Schistosomiasis, which is the second most important parasitic infection after malaria in terms of its socioeconomic impact, is responsible for the loss of an estimated 4.5 million disability-adjusted life years (DA...LYs) worldwide. Schistosomiasis, including both intestinal and urinary forms of the disease, occurs in 78 countries across the globe. An estimated 240 million people are infected, with more than 779 million living at risk globally. The majority of those infected and those at risk for infection live in low-income countries, and approximately 80% of the morbidity occurs in impoverished communities and households in sub-Saharan Africa. Within Uganda, 91 of the 134 districts are endemic for intestinal schistosomiasis caused by Schistosoma mansoni, and the eastern region, especially along Lake Victoria, has one of the highest S. mansoni burdens worldwide. Schistosoma haematobium is only endemic in the five districts of the Lango region in northern Uganda.

The goal of this course is to provide participants with the foundational skills needed to begin the development, implementation and ongoing improvement of a congenital anomalies surveillance programme, in particular for countries with limited resources. It focuses on the methodology needed to devel...op either population-based or hospital based surveillance programmes.
A set of congenital anomalies will be used as examples throughout this course. The specific examples used are typically severe enough that they would probably be captured within the first few days after birth, have a significant public health impact and, for some of them, have the potential for primary prevention.

Buruli ulcer is a chronic, progressive skin disease caused by infection with Mycobacterium ulcerans. It is currently considered to be one of the neglected tropical diseases; less common than tuberculosis but more common than leprosy. The initial lesion is a painless subcutaneous nodule, usually less... than 5 cm diameter and adherent to skin. The nodule typically breaks down centrally after days to weeks forming an ulcer with undermined edges. Thus, the external appearance of the ulcer underestimates the true size of the affected area. The patient remains well and there is no pain unless secondary bacterial infection occurs. Other forms of M. ulcerans disease include a firm plaque lesions that behaves in the same way as the nodule or an oedematous lesion that is more aggressive and extends rapidly resulting in a very large ulcer.
Any age group can be affected by Buruli ulcer diseases, but the incidence peaks at 5 to 15 years. Ulcers are most frequently on the limbs but can be on the trunk or head, sometimes with catastrophic consequences such as loss of sight or loss of breast or genital tissue. Healing close to a joint can result in contracture, and sometimes there is so much tissue destruction on a limb that amputation is unavoidable. Occasionally osteomyelitis occurs in bone adjacent to a skin lesion but involvement of other organs is rare. Disseminated disease with HIV has been reported.
