Reviewing essential public health functions in the Eastern Mediterranean Region post COVID-19 pandemic: a foundation for system resilience.

The COVID-19 pandemic exposed vulnerabilities in many health systems worldwide with profound implications for health and society. The public health challenges experienced during the pandemic have highlighted the importance of resilient health systems, that can adapt and transform to meet the population's evolving health needs. Essential public health functions (EPHFs) offer a holistic, integrated and sustainable approach to public health by contributing to achieving several health priorities and goals. In recent years, there has been a focused effort to conceptualise and define the EPHFs. In this paper, we describe the collaborative approach undertaken by the WHO Eastern Mediterranean Region (EMR) and UK Health Security Agency and present the findings and results of the revised EPHFs, in view of lessons learnt from the COVID-19 pandemic and the current priorities for countries across the EMR. This included conducting a desktop review, a gap and bottleneck analysis and stakeholder consultation to arrive at the revised EPHF model including four enablers and nine core functions, including a new function: public health services. The EPHFs will offer countries a complementary and synergistic approach to strengthen health systems and public health capacities and contribute to the region's ability to effectively respond to future health challenges and emergencies. By focusing on the EPHFs, countries can work towards ensuring health security as an integral goal for the health system besides universal health coverage, thus strengthening and building more resilient and equitable health systems.

Hepatoprotective effect of methanolic extract of Iris florentina L. on paracetamol-induced liver toxicity in rats.

Despite of plethora of research on hepatoprotective potential of medicinal plants, there is still need to discover potential plants with hepatoprotective activity. Iris florentina L. is a medicinal plant with traditional claims but ignored investigation regarding its hepatoprotective effects. The current study is aimed to investigate the hepatoprotective potential of I. florentina L. methanolic extract on paracetamol (PCM)-induced liver injury. The phytochemical and HPLC screening was done which showed the presence of potential constituents including flavonoids and phenols. For investigating the hepatoprotective effect of I. florentina L. methanolic extract, rats were given five different treatments for seven consecutive days. The normal control (group 1) was administered with normal saline, group 2 (Diseased) received paracetamol and group 3 (Standard) was given silymarin as reference drug. In group 4 and 5 (Treated), I. florentina L. methanolic extract (250 and 500mg/kg) were administered. Different serum biomarkers and histopathological studies were performed to assess the recovery caused by PCM in comparison to diseased group. The treatment of I. florentina methanolic extract significantly improve the serum biomarkers and restored the hepatic injury towards normal, indicating the hepatoprotective potential. Thus, we can conclude that I. florentina have significantly reversed the damage caused by paracetamol in hepatotoxic rat model due to their potential phytochemical constituents.

National outbreak of Pseudomonas aeruginosa associated with an aftercare solution following piercings, July to September 2016, England.

We report a national Pseudomonas aeruginosa outbreak from a common source following piercings between July and September 2016 in England. The multi-agency outbreak investigation included active case finding, microbiological testing of environmental samples and case specimens including Variable Number Tandem Repeat (VNTR) typing and a retrospective cohort study. Overall, 162 outbreak cases (29 confirmed, 14 probable and 119 possible) and 14 non-outbreak cases were identified; all confirmed cases had ear piercings (93% cartilage). Outbreak cases were predominantly female (95%) and had a median age of 18 years (interquartile range: 13-56 years). Nineteen outbreak cases required surgery under general anaesthetic The same outbreak VNTR type (11,3,5,3,3,3,6,4,7) was isolated from bottles of an aftercare solution from a single manufacturer and in specimens from confirmed cases who attended eight different piercing studios supplied with this product. In the cohort study, use of aftercare solution was associated with becoming a case (aOR: 4.60, 95% confidence interval: 1.65-12.90). Environmental, microbiological and epidemiological investigations confirmed that contamination during production of aftercare solution was the source of this national outbreak; highlighting challenges in the regulation of a cosmetic products used in the piercing industry and that guidance on piercing aftercare may need to be reviewed.

Emergence of a multidrug-resistant (ASSuTTm) strain of Salmonella enterica serovar Typhimurium DT120 in England in 2011 and the use of multiple-locus variable-number tandem-repeat analysis in supporting outbreak investigations.

In summer 2011, two outbreaks of a unique, multidrug-resistant strain of Salmonella enterica serovar Typhimurium phage type 120 (DT120) occurred mainly in the Midlands, England. The first outbreak occurred among guests attending a wedding in July 2011 ('Wedding outbreak'), followed by a more geographically dispersed outbreak in August and September 2011 ('Midlands outbreak'). Fifty-one cases were confirmed. Detailed epidemiological and environmental health investigations suggested that pork was the most likely source of both outbreaks. All human samples and one pork sample showed the specific multiple-locus variable-number tandem-repeat analysis (MLVA) profile 3-11-12-NA-0211, with at most two loci variations. Trace-back investigations suggested a link to a butcher's shop and a pig farm in the East Midlands. The investigations highlight the utility of molecular analysis (MLVA) in supporting epidemiological investigations of outbreaks caused by S. Typhimurium DT120. Safe handling and cooking of pork by food business operators and consumers are key interventions to prevent future outbreaks.
