Decontamination of medical devices plays an important role in the prevention of health care-associated infections. It includes cleaning, disinfection and/or sterilization. The processes involved in decontamination are complex, require specific infrastructure and equipment, and involve several sequen...tial steps that need to be performed correctly – from device collection and receipt by the decontamination unit to processing, storage and distribution throughout the facility. Quality control procedures (such as validation) at each step of the decontamination process are of the utmost importance to ensure the correct functioning of the equipment and processes. This aide-memoire presents a concise overview of important advice and key elements at a glance.

The Democratic Republic of Timor-Leste has the highest TB incidence rate in the South East Asian Region - 498 per 100,000, which is the seventh highest in the world. In Timor-Leste TB is the eighth most common cause of death.
The salient observations are as follows:
In 2018, 487 (12.5%) of the... 3906 notified TB patients were tested for RR-TB and only 12 lab confirmed RR-TB patients were initiated on standard MDR-TB treatment of 20-months duration, (a 3-fold increase in RR-TB detection compared with 2017). This amounts to treatment coverage of only 17% of 72 estimated MDR/RR-TB among notified TB patients (3906) and 5% of 240 estimated incident MDR-TB patients as compared to 62% treatment coverage of 6300 incident drug sensitive TB patients estimated in TLS. The treatment success in the 2016 annual cohort of 6 MDR-TB patients has been reported at 83%. 80% of TB patients know their HIV Status with around 1% TB-HIV co-infection, 37/ 77 (48%) TB-HIV Co-infection Detected. Of the 387 PLHIV currently alive on ART, exact status on TB screening and testing is unknown. % of PLHIV newly enrolled in HIV care who received IPT is not known.
In 2018, the mortality rate for TB was 94 deaths per 100,000 people (1200 per annum) in TL with an increasing mortality trend (Figure 1), despite TB services being available for nearly two decades.
A survey of catastrophic costs due to TB (2016) highlights that 83% of TB patients are reported to be facing catastrophic costs due to the disease. This is the highest rate in the world.

The provision of safe and efficacious blood and blood components for transfusion or manufacturing use involves a number of processes, from the selection of blood donors and the collection, processing and testing of blood donations to the testing of patient samples, the issue of compatible blood and ...its administration to the patient. There is a risk of error in each process in this “transfusion chain” and a failure at any of these stages can have serious implications for the recipients of blood and blood products. Thus, while blood transfusion can be life-saving, there are associated risks, particularly the transmission of bloodborne infections.
Screening for transfusion-transmissible infections (TTIs) to exclude blood donations at risk of transmitting infection from donors to recipients is a critical part of the process of ensuring that transfusion is as safe as possible. Effective screening for evidence of the presence of the most common and dangerous TTIs can reduce the risk of transmission to very low levels.

La fourniture de sang et de produits sanguins sûrs et efficaces pour la transfusion ou la fabrication d’autres produits sanguins fait intervenir un certain nombre de processus, allant de la sélection des donneurs de sang et de la collecte, au traitement et au dépistage des dons de sang ainsi qu...’à l’analyse des échantillons des malades, à la délivrance de sang compatible et à son administration au patient. Il existe un risque d’erreur à chaque étape de la « chaîne de transfusion », et une défaillance à une quelconque de ces étapes peut avoir des conséquences graves pour les receveurs du sang ou des produits sanguins. Si la transfusion sanguine peut sauver des vies, elle comporte aussi des risques, en particulier la transmission des infections par le sang.
Le dépistage des infections transmissibles par transfusion (ITT) en vue d’exclure les dons de sang présentant un risque de transmettre une infection du donneur aux receveurs est une étape critique du processus visant à garantir au mieux la sécurité des transfusions. Un dépistage efficace des agents transmissibles par le sang les plus courants et les plus dangereux peut réduire le risque de transmission à des niveaux très faibles.

Personne ne se rend dans un établissement de soins de santé pour tomber malade. On s’y rend pour aller mieux, pour accoucher, pour se faire vacciner. Cependant, des centaines de millions de gens sont confrontés à un risque accru d’infection ...quand ils se font soigner dans des établissements de santé où les services de première nécessité font défaut, y compris les services d’approvisionnement en eau, d’assainissement et d’hygiène (WASH) et les services de gestion des déchets médicaux. Non seulement l’absence de services WASH dans les établissements de santé compromet la sécurité sanitaire des patients et leur dignité, mais il peut éventuellement exacerber la propagation d’infections résistant aux antimicrobiens et compromettre les efforts faits en vue de l’amélioration de la santé maternelle et infantile.

This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector. The flagellate mainly colonizes the intestinal tract of the insect. The effect of triatomines on trypanosomes is indicated by susceptibility and refractoriness phenom...ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.

Cardiovascular disease is a major cause of disability and premature death throughout the world, and contributes substantially to the escalating costs of health care. The underlying pathology is atherosclerosis, which develops over many years and is usually advanced by the time symptoms occur, genera...lly in middle age. Acute coronary and cerebrovascular events frequently occur suddenly, and are often fatal before medical care can be given. Modification of risk factors has been shown to reduce mortality and morbidity in people with diagnosed or undiagnosed cardiovascular disease.
This publication provides guidance on reducing disability and premature deaths from coronary heart disease, cerebrovascular disease and peripheral vascular disease in people at high risk, who have not yet experienced a cardiovascular event. People with established cardiovascular disease are at very high risk of recurrent events and are not the subject of these guidelines. They have been addressed in previous WHO guidelines.
Several forms of therapy can prevent coronary, cerebral and peripheral vascular events. Decisions about whether to initiate specific preventive action, and with what degree of intensity, should be guided by estimation of the risk of any such vascular event. The risk prediction charts that accompany these guidelinesb allow treatment to be targeted accord-
ing to simple predictions of absolute cardiovascular risk.
Recommendations are made for management of major cardiovascular risk factors through changes in lifestyle and prophylactic drug therapies. The guidelines provide a framework for the development of national guidance on prevention of cardiovascular disease that takes into account the particular political, economic, social and medical circumstances.

Infectious diseases are constantly in transition. New diseases develop, known dis-eases become widespread or reemerge, and occasionally a disease is eradicated.Infectious diseases such as HIV, tuberculosis, and cholera are significant causes ofillness and death in many parts of the world. Health car...e personnel are on thefront lines, helping to protect their clients from infectious diseases and treatingthem when infections occur. During the course of their work, health care person-nel perform clinical procedures or other activities that can expose both them andtheir clients to potentially infectious microorganisms. Many of their clients aresick and thus may be more susceptible to infections or may have infections thatcan be transmitted to others. Fortunately, all staff working at health care facilities can perform simple proce-dures to minimize risk—to themselves and clients—and reduce the spread ofinfections. These practices can be integrated at minimal cost into the routineworkday at clinics and hospitals around the world. This reference booklet isspecifically designed for use at all levels of the health care system, from thelargest hospitals to the smallest dispensaries or health posts, in settings whereresources are scarce. This booklet, which was first published in 1999, has now been updated. Whilemost practices remain the same, there have been a few important changes—forexample, in recommendations related to hand hygiene and standard precautions.Nonetheless, this booklet continues to present practical recommendations forsimple and relatively low-cost procedures that can be implemented anywhere,with basic supplies and little to no high-technology equipment.
