A role for nuclear techniques
Antimicrobials play a critical role in the treatment of human and animal (aquatic and terrestrial) diseases, which has led to their widespread application and use. Antimicrobial resistance (AMR) is the ability of microorganisms to stop an antibiotic, such as an antimic...robial, antiviral or antimalarial, from working against them. Globally, about 700 000 deaths per year arise from resistant infections as a result of the fact that antimicrobial drugs have become less effective at killing resistant pathogens. Antimicrobial chemicals that are present in environmental compartments can trigger the development of AMR. These chemicals can also cause antibiotic-resistant bacteria (ARB) to further spread antibiotic resistance genes (ARG) because they may have an evolutionary advantage over non-resistant bacteria.

The extensive use of antimicrobials in human and veterinary medicine in recent years has accelerated the emergence and spread of resistant microorganisms. This situation has been worsened by the lack of investment in developing new effective antibiotics. The severity of the consequences is clear to ...see: it is estimated that each year, drug-resistant infections result in at least 25 000 patient deaths and cost the EU EUR 1,5 billion in healthcare costs and through loss of productivity

HIV infection, due to the immunosuppressant that leads, nowadays constitutes an aggravating factor of endemic tuberculosis. Tuberculosis remains a huge burden to human health, even in the early 21st century. The situation is deteriorating in many countries, particularly because of the synergy with t...he HIV epidemic and the emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR) tuberculosis. The urgent development of new tools that can improve the diagnosis, prevention and/or treatment of tuberculosis and other major mycobacterium diseases depends largely on the progress of basic and applied research. Faced with this situation, there is an urgent need for effective strategies and actions to permanently solve the problem of this endemic disease whose impact is too negative on people’s lives.

Antimicrobial resistance (AMR) is an important public health concern shared by developed and developing countries. In developing countries the burden of infectious diseases is greater and exacerbated by limited access to, and availability and affordability of, antimicrobials required to treat infect...ions caused by AMR organisms. With drugs not listed on the essential drugs list (EDL), problems of increased morbidity, costs of extended hospitalisation and mortality are extremely serious. The problem of susceptibility to and spread of infections caused by multidrug-resistant (MDR) infectious agents is fuelled by factors such as limited access to clean water and sanitation to ensure personal hygiene, malnutrition, and the HIV/TB epidemic.

The global increase of healthcare-associated infections (HAI) presents a growing concern in healthcare worldwide. According to the European Centre for Disease Prevention and Control (ECDC), the annual number of HAI exceeds 2.6million and produces the highest estimated amou...nt of disability-adjust-ed-life-years, surpassing all other reported communicable diseases in the European Union and European Economic Area. Multi-drug-resistant Gram-negative (MDR-GN) bacteria have become increasingly common as a cause for HAI, such as central line-as-sociated bloodstream infections, wound or surgical site infections and catheter-associated urinary tract infections

In Kenya, the bacterial infections that contribute most to human disease are often those in which re-‐sistance is most evident. Examples are multidrug-‐resistant enteric bacterial pathogens such as typhoid, ... diarrhoeagenic Escherichia coli and invasive non-‐typhi salmonella, penicillin-‐resistant Streptococcus pneu-‐moniae, vancomycin-‐resistant enterococci, methicillin-‐resistant Staphylococcus aureus and multidrug-‐re-‐sistant Mycobacterium tuberculosis. Resistance to medicines commonly used to treat malaria is of particu-‐lar concern, as is the emerging resistance to anti-‐HIV drugs. Often, more expensive medicines are required to treat these infections, and this becomes a major challenge in resource-‐poor settings.

Spread of resistance to antimicrobial agents (AMR) does not know national borders and has reached dimensions, which require immediate actions at the national, regional and global levels.
Antibiotic resistance is a natural biological response to improper use of antimicrobial agents (AMA); increasing... number of essential drugs, which become ineffective, contributing to selection, survival and replication of resistant strains of microorganisms. When chosen antimicrobials prove to be ineffective, the second- or third-line drugs need to be used although
in the majority of cases these drugs are more expensive, less safe and not always available.

Solidarity” is an international clinical trial to help find an effective treatment for COVID-19, launched by the World Health Organization and partners.
The Solidarity Trial will compare four treatment options against standard of care, to assess their relative effectiveness against COVID-19. By... enrolling patients in multiple countries, the Solidarity Trial aims to rapidly discover whether any of the drugs slow disease progression or improve survival. Other drugs can be added based on emerging evidence.
Until there is sufficient evidence, WHO cautions against physicians and medical associations recommending or administering these unproven treatments to patients with COVID-19 or people self-medicating with them. WHO is concerned by reports of individuals self-medicating with chloroquine and causing themselves serious harm.

This tool is designed to help governments, partners, and other stakeholders to estimate potential requirements for essential supplies to respond to the current pandemic of COVID-19. Although it gives users with an estimation of the number of cases, this calculator is not an epidemiological calculato...r.
The focus of this tool is to forecast essential supplies: it includes estimation of personal protective equipment, diagnostic equipment, biomedical equipment for case management, essential drugs for supportive care, and consumable medical supplies.
The COVID-19 ESFT tool is intended to be complimentary to the Health Workforce tools (Adaptt and the Workforce Estimator). Both tools use the same base clinical attack rate ranges and classify health workforce using ILO ISCO codes, but their outputs are intentionally different due to their primary focus.

The internationally recognized criteria for diagnosis of neurocysticercosis include a requirement for neuroimaging techniques, such as computerized tomography (CT) and/or magnetic resonance imaging (MRI), ideally supported by serology. These facilities are not available in all settings, especially i...n rural areas of low-income countries, making it difficult to identify and treat patients. Additionally, there is controversy about the role, type and duration of anthelmintic, antiinflammatory and antiepileptic drug (AED) treatments for different forms of neurocysticercosis.
These guidelines were developed to assist health-care providers in appropriate, evidence-based management of parenchymal neurocysticercosis. The guidelines do not address other forms of neurocysticercosis and do not include management of extraparenchymal disease (including cysticerci in the cerebral ventricles or subarachnoid space). The aim of the guidance is to improve decision-making to ensure appropriate patient care and to avoid misdiagnoses and inappropriate treatment of patients with neurocysticercosis.

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

RESULTS: Between 76 and 97% of the PHCS offered RMCAH services before the lockdown. Except in antenatal, delivery and adolescent care, there was a decline of between 2 and 6% in all the services during the lockdown and up to 10% decline after the lockdown with variation across and within States. Dur...ing the lockdown. Full-service delivery was reported by 75.2% whereas 24.8% delivered partial services. There was a significant reduction in clients' utilization of the services during the lockdown, and the difference between States before the pandemic, during, and after the lockdown. Reported difficulties during the lockdown included stock-out of drugs (25.7%), stock-out of contraceptives (25.1%), harassment by the law enforcement agents (76.9%), and transportation difficulties (55.8%). Only 2% of the PHCs reported the availability of gowns, 18% had gloves, 90.1% had hand sanitizers, and a temperature checker was available in 94.1%. Slightly above 10% identified clients with symptoms of COVID-19.
CONCLUSIONS: The large proportion of PHCs who provided RMCAH services despite the lockdown demonstrates resilience. Considering the several difficulties reported, and the limited provision of primary protective equipment more effort by the government and non-governmental agencies is recommended to strengthen delivery of sexual and reproductive health in primary health centres in Nigeria during the pandemic.

In the face of rapid increases in the number of hospitalizations due to COVID-19 in Latin America and the Caribbean, coupled with shortages of human and material resources, including medical equipment and gases, there is a need to redesign models of care in the Region to optimize available resources... and ensure that more patients receive the quantity and quality of oxygen they need. Oxygen is included in the World Health Organization’s list of essential medicines and is used to care for patients at all levels of integrated health services networks. The efficacy of oxygen use in the treatment of patients with respiratory conditions caused by COVID-19 has been demonstrated, but there is great opportunity to improve the effectiveness of its use if it is used in a rational, sustainable, and safe way. Bearing in mind that the efficacy of a health technology is measured by its benefit under actual conditions of use, practical actions can be taken to improve the use of medical oxygen and avoid oxygen shortages. A drug is considered to be used rationally when patients receive it according to their clinical needs, in doses appropriate to their individual needs, for an appropriate period, and at a low cost to them and their community. By providing instruction on the rational use of oxygen and promoting it, negative repercussions can be avoided, such as loss of efficacy as a result of activities related to oxygen storage, distribution, and administration. Rational use of oxygen also involves controlling waste due to leaks in storage and distribution systems, use of gas at incorrect pressures, use of incorrectly adjusted flowmeters, and disconnections, among other problems. Another aspect to consider is the provision of adequate technical support for all oxygen production systems, in terms of maintenance and calibration, availability of electrical energy, and specific knowledge about these systems. For these reasons, a set of guidelines has been put together for the development of an efficient management system to deal with situations of oxygen scarcity, both now and in the future.

The larval stage of the parasite Taenia solium can encyst in the central nervous system causing neurocysticercosis, which is the main cause of acquired epilepsy in the countries in which the parasite is endemic. Endemic areas are those with the presence (or likely presence) of the full life cycle of... Taenia solium. The parasite is most prevalent in poor and vulnerable communities in which pigs roam free, open defecation is practiced, basic sanitation is deficient, and health education is absent or limited. Several tools are available for the control of Taenia solium. Preventive chemotherapy for Taenia solium taeniasis, which is directed at the adult tapeworm, is one of them. Other tools focus on pig management, pig vaccination and treatment, sanitation and hygiene, and community education. Three potential drugs—niclosamide, praziquantel, and albendazole—have been considered for use for preventive chemotherapy in Taenia solium taeniasis control programs through mass drug administration or targeted chemotherapy. In this Guideline, we provide recommendations for preventive chemotherapy in Taenia solium-endemic areas using niclosamide, praziquantel, or albendazole, including at which dose and in which population groups.
