Hank introduces us to biogeochemical cycles by describing his two favorites: carbon and water. The hydrologic cycle describes how water moves on, above, and below the surface of the Earth, driven by energy supplied by the sun and wind. The carbon cycle does the same... for carbon!

The ongoing COVID-19 pandemic presents an exceptional and unprecedented challenge for competent authoritiesa with responsibilities for national food safety control systemsb to continue conducting routine functions and activities in accordance with national regulations... and international recommendations. In many countries, competent authority staff are largely working from home, teleworking being the normal practice, and all face-to-face meetings cancelled or rescheduled as teleconferences. It is challenging to maintain, without interruption, routine activities such as the inspection of food business operations, certifying exports, control of imported foods, monitoring and surveillance of the safety of the food supply chain, sampling and analysis of food, managing food incidents, providing advice on food safety and food regulations for the food industry, and communicating on food safety issues with the public.

The sixteenth meeting of the Strategic and Technical Advisory Group for Neglected Tropical Diseases (STAG-NTD) was held as a hybrid meeting, 27–28 September 2022.
Dr Ren Minghui, Assistant Director-General, Universal Health Coverage/Communicable and Noncommunicable Diseases, welcomed participan...ts to the meeting. He said the World Health Organization’s Department of Control of Neglected Tropical Diseases (WHO/NTD) was in a state of transition. Following the death of the late esteemed Director Dr Mwelecele Ntuli Malecela earlier in the year, Dr Gautam Biswas had taken over as Acting Director but would soon retire; the appointment of a new Director was under way. Owing to rotation of STAG-NTD members, this would be the last meeting for some and the first meeting for several new participants. The work however would continue with the same commitment. Discussions over the next two days would focus on critical issues regarding recovery of NTD services following the disruptions caused by coronavirus disease (COVID-19), which had impacted many health services worldwide. He looked forward to receiving the advice and guidance of STAG-N

For the molecular diagnosis of Chagas disease by real-time PCR (polymerase chain reaction), optimization of diagnostic accuracy is desirable. The detection limit of real-time PCR assays for the diagnosis of Trypanosoma cruzi in human serum is affected by various influences including the choice of th...e nucleic acid extraction assay. In this study, three nucleic acid extraction assays were compared regarding their influence on the sensitivity of a T. cruzi-specific real-time PCR with 62 reference sera containing T. cruzi target DNA (deoxyribonucleotide acid). More than 95% of the positive sera were correctly identified after all three nucleic acid extraction strategies with a detection rate ranging from 96.8% (60/62) for the worst assay to 100% (62/62) for the best one. A matched pairs analysis for the comparison of the cycle threshold (Ct) values obtained with the 59 reference samples with positive real-time PCR results after all three nucleic acid extraction schemes indicated differences in a range of about 3 Ct steps. Summarized, all three compared nucleic acid extraction schemes were basically suitable for T. cruzi-specific PCR from serum with some minor differences. However, in the case of low quantities of circulating parasite DNA in the serum of a patient with Chagas disease, even minor effects can make a difference in the individual diagnosis.

On 6 February at 4:17 am, a 7.8 degrees magnitude earthquake struck southern Turkey near Syria’s
northern border. The US Geological Survey said the earthquake was centered about 33 km (20 miles)
from Gaziantep, a major city and provincial capital. Tremors were felt as far away as Lebanon, Greece...,
Palestine, and the island of Cyprus. Another big earthquake was felt on the same day at around 1:24
pm local time, largely in the same affected areas. Aftershocks will continue to shake the area as fault
lines adjust to such a huge initial tremor. There’s even a risk—albeit a small one—of an aftershock
bigger than the original quake.

Monitoring financial protection and utilization of health services in Mongolia 2009-2018 is based on national representative household socioeconomic surveys. The study finds that between 2009 and 2018, despite ambitious health reforms, the incidence of catastrophic health spending and impoverishing ...spending at the relative poverty line have increased. These increases were mainly driven by out-of-pocket spending on medicines and inpatient care. In the same period, inequity in access to and utilization of health services remained constant among population groups. Evidence suggests health financing policies need to be further strengthened to make progress towards universal health coverage. Continuous tracking of out-of-pocket payments and service utilization to inform policymaking is needed.

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.

Paying for performance (P4P) provides financial incentives for providers to increase the use and quality of care. P4P can affect health care by providing incentives for providers to put more effort into specific activities, and by increasing the amount of resources available to finance the delivery ...of services. This paper evaluates the impact of P4P on the use and quality of prenatal, institutional delivery, and child preventive care using data produced from a prospective quasi-experimental evaluation nested into the national rollout of P4P in Rwanda. Treatment facilities were enrolled in the P4P scheme in 2006 and comparison facilities were enrolled two years later. The incentive effect is isolated from the resource effect by increasing comparison facilities’ input-based budgets by the average P4P payments to the treatment facilities. The data were collected from 166 facilities and a random sample of 2158 households. P4P had a large and significant positive impact on institutional deliveries and preventive care visits by young children, and improved quality of prenatal care. The authors find no effect on the number of prenatal care visits or on immunization rates. P4P had the greatest effect on those services that had the highest payment rates and needed the lowest provider effort. P4P financial performance incentives can improve both the use of and the quality of health services. Because the analysis isolates the incentive effect from the resource effect in P4P, the results indicate that an equal amount of financial resources without the incentives would not have achieved the same gain in outcomes.

Cognitive deficits in schizophrenia can massively impact functionality and quality of life, furthering the importance of cognitive training. Despite the development of the field in Europe and in the United States, no programmes have been developed and tested in developing countries. Different cultur...al backgrounds, budget restrictions, and other difficulties may render treatment packages created in high income countries difficult for adoption by developing nations. We performed a pilot double-blind, randomized, controlled trial in order to investigate the efficacy and feasibility of an attention and memory training programme specially created in
a developing nation. The intervention used simple, widely available materials, required minimal infrastructure, and was conducted in groups.The sample included seventeen stable Brazilians with schizophrenia. Sessions were conducted weekly during five months. The cognitive training group showed significant improvements in inhibitory control and set-shifting over time. Both groups showed improvements in symptoms, processing speed, selective attention, executive function, and long-term visual memory. Improvements were found in the control group in long-term verbal memory and concentration. Our findings reinforce the idea that cognitive training in schizophrenia can be constructed using simple resources and infrastructure, facilitating its adoption by developing countries, and it may improve cognition.

Seit über einem Jahr hat die Corona-Pandemie große Veränderungen für alle Menschen in nahezu jedem Lebensbereich herbeigeführt. Geflüchtete in (Erst-) Aufnahmeeinrichtungen und Gemeinschaftsunterkünften sind in besonderem Maße von der Pandemie betroffen, da die vorgefundenen Wohnbedingungen ...einen kaum ausreichenden Schutz zulassen. Obwohl gerade die Bewohner*innen von Sammelunterkünften dem Virus stark ausgesetzt sind, hat diese Gruppe nicht ausreichend Beachtung und Schutz gefunden. Ergriffene Maßnahmen wie etwa Kollektiv- oder auch Kettenquarantänen haben die Lebensbedingungen der Bewohner*innen noch weiter erschwert, mit gravierenden Auswirkungen auf das Asylverfahren, Gesundheit, Beruf, Ausbildung und Schule und so letztendlich auch auf ihre soziale Teilhabe.
