Participatory Mathematical Modeling Approach for Policymaking during the First Year of the COVID-19 Crisis, Jordan.

We engaged in a participatory modeling approach with health sector stakeholders in Jordan to support government decision-making regarding implementing public health measures to mitigate COVID-19 disease burden. We considered the effect of 4 physical distancing strategies on reducing COVID-19 transmission and mortality in Jordan during March 2020-January 2021: no physical distancing; intermittent physical distancing where all but essential services are closed once a week; intermittent physical distancing where all but essential services are closed twice a week; and a permanent physical distancing intervention. Modeling showed that the fourth strategy would be most effective in reducing cases and deaths; however, this approach was only marginally beneficial to reducing COVID-19 disease compared with an intermittently enforced physical distancing intervention. Scenario-based model influenced policy-making and the evolution of the pandemic in Jordan confirmed the forecasting provided by the modeling exercise and helped confirm the effectiveness of the policy adopted by the government of Jordan.

The Behaviour of Stratified Fabrics of Aramid Fibres under Stabbing Conditions.

This paper presents research on several factors influencing the stabbing behaviour of stratified panels made of aramid fabric Twaron® SRM509 Teijin Aramid BV (Arnhem, The Netherlands). The inputs in the test campaign were the number of layers, the impact energy, and the sample size. Tests were performed on small samples (130 mm × 130 mm) on an Instron® CEAST 9350 drop-tower impact system (Norwood, MA, USA) and on larger samples (400 mm × 400 mm) using a test installation with the same values of the impact energy. Knife type S1 was used, with the geometry recommended in NIJ Standard 0115.00 Stab Resistance of Body Armor SEM, and macro photography investigations revealed the failure mechanisms of panel, layers and fibres. A very important conclusion of this study regarding the stabbing performance of fabric Twaron® SRM 509 in particular, but also in general for panels for body protection is that a research study could start on small size samples, with an accurately instrumented machine, in order to establish the influence of significant factors of stab resistance (energy level, number of layers in a panel, etc.), as these samples are less expensive and less time consuming, but the study should be continued to examine larger size samples. The obtained data are useful for the prototype.

Migrant health during public health emergencies: The Ebola crisis in Uganda.

The Ebola virus diseases (EVD) declared in Uganda in September 22, 2022, has spread to seven districts by early November, with a total of 131 confirmed cases and 48 deaths. Public health emergency response in Uganda deserves a specific and tailored approach due to the current population composition, which accounts to around 1.4 million refugees and asylum seekers. Indeed, Uganda is a potential example of how increased international connectivity has resulted in forced migration with profound impacts on global health. In consideration of the vulnerability of refugees and migrants due to poor living, housing, and working conditions, inclusive policies are even more critical during public health emergencies. Inclusivity lessons learned from COVID-19 in several settings, such as access to treatment and vaccination for all individuals regardless of nationality, residence, and legal status, would be critical to ensure wellbeing of migrants, refugees and host communities.

Risk as catalyst for positive change: lessons learnt from public health readiness for cholera in Jordan.

This case study highlights how a looming health crisis was leveraged as drivers for positive change for the health sector, in line with the health security agenda. In Jordan, several authorities are mandated by law to manage health emergencies. Following the declaration of outbreaks of cholera in Iraq, Lebanon and Syria, health authorities in Jordan called for a series of emergency meetings during September 2022 to discuss implications around travel and trade as well as shared waters. WHO was part of the consultations and provided guidance on the application of the International Health Regulations 2005. As the risk for cholera importation persisted, the Ministry of Health assumed its leadership role for the overall health sector response while the Jordanian Center for Disease Control assumed a coordinating function. Roles and responsibilities were enshrined in the National Cholera Preparedness and Response Plan. In consideration of the vulnerability of refugee camps and settlements towards Cholera, the existing Jordan humanitarian coordination platforms such as the Health Sector Working Group were used to share information and to coordinate activities. A whole-of-government risk assessment during December 2022 was complemented by a field visit at Zaatari refugee camp. This helped assess the risk and readiness for a cholera outbreak in Jordan and informed priority activities, such as the establishment of a national risk communication and community engagement working group as well as training on case management.

Chronic hyponatremia in patients with proximal femoral fractures after low energy trauma: A retrospective study in a level-1 trauma center.

INTRODUCTION: We evaluated the prevalence and influence of chronic hyponatremia in patients with low energy trauma. We also investigated the influence of medication and diseases on hyponatremia. MATERIAL AND METHODS: This retrospective study included 314 cases of proximal femoral fracture due to low energy trauma. Patients were treated in the University Medical Center Goettingen within 3 years. Hyponatremia was defined as serum sodium <135 mmol/L at admission. RESULTS: Overall, 15.6% of patients in the low energy trauma group had hyponatremia. Among patients older than 80 years, women showed distinctly higher rates of hyponatremia (female: 16.4%; male: 5.9%). In contrast only 4.7% of patients who underwent elective hip arthroplasty showed hyponatremia. Patients on sartanes and aldosterone antagonists showed significantly higher rates of hyponatremia. Alcoholism was significantly associated with hyponatremia. CONCLUSIONS: We confirmed a high prevalence of chronic hyponatremia in patients with fractures due to low energy trauma. Our data underscore chronic hyponatremia as a contributing factor to hip fractures. Women older than 80 have a higher risk of developing hyponatremia. Sartanes, aldosterone antagonists, and alcohol disease are associated with hyponatremia. Treating hyponatremia may decrease the risk of fracture after low energy trauma. Therefore, physicians of different specialties should focus on treatment of chronic hyponatremia to reduce the fracture rate associated with low energy trauma.
