Mapping the international health regulations monitoring and evaluation framework: an expert consultation, triangulation crosswalk and quantitative analysis.

The International Health Regulations Monitoring and Evaluation Framework (IHRMEF) includes four components regularly conducted by States Parties to measure the current status of International Health Regulations (IHR) 2005 core capacities and provide recommendations for strengthening these capacities. However, the four components are conducted independently of one another and have no systematic referral to each other before, during or after each process, despite being largely conducted by the same team, country and support organisations. This analysis sets out to identify ways in which IHRMEF components could work more synergistically to effectively measure the status of IHR core capacities, taking into account the country's priority risks.

Transient aphonia following spinal anesthesia during emergency cesarean section: Case report and review of literature.

Subarachnoid block with local anesthetic agents is a well-established anesthesia technique among pregnant females for labor analgesia and cesarian delivery. Although it is considered a reliable and safe technique for both mothers and fetuses, unexpected high or low levels of block may occur due to accidental injection of these agents into different meningeal spaces other than intended. Hypotension, bradycardia, headache, and failed anesthesia are common complications of spinal anesthesia.

HLA-B27 Negative Reactive Monoarthritis of the Hip Joint Triggered by Scrub Typhus: A Case Report.

Unlabelled: Scrub typhus is common in rural Nepal's southern plains, but its diagnosis remains difficult due to a lack of clinical suspicion and poor diagnostic resources. The absence of common manifestations of the condition including eschar might further complicate this problem and may result in treatment delays. We report a case of scrub typhus with the primary presentation of reactive monoarthritis of the left hip joint in a 19-year-old male who presented with difficulty in walking, and pain over the left hip joint.

Hedgehog Autoprocessing: From Structural Mechanisms to Drug Discovery.

Hedgehog (Hh) signaling plays pivotal roles in embryonic development. In adults, Hh signaling is mostly turned off but its abnormal activation is involved in many types of cancer. Hh signaling is initiated by the Hh ligand, generated from the Hh precursor by a specialized autocatalytic process called Hh autoprocessing.

The role of health systems for health security: a scoping review revealing the need for improved conceptual and practical linkages.

Background: Practical links between health systems and health security are historically prevalent, but the conceptual links between these fields remain under explored, with little on health system strengthening. The need to address this gap gains relevance in light of the COVID-19 pandemic as it demonstrated a crucial relationship between health system capacities and effective health security response. Acknowledging the importance of developing stronger and more resilient health systems globally for health emergency preparedness, the WHO developed a Health Systems for Health Security framework that aims to promote a common understanding of what health systems for health security entails whilst identifying key capacities required.

Structure-Activity Relationship of Carbon Nitride Dots in Inhibiting Tau Aggregation.

Due to the numerous failed clinical trials of anti-amyloid drugs, microtubule associated protein tau (MAPT) now stands out as one of the most promising targets for AD therapy. In this study, we report for the first time the structure-dependent MAPT aggregation inhibition of carbon nitride dots (CNDs). CNDs have exhibited great promise as a potential treatment of Alzheimer's disease (AD) by inhibiting the aggregation of MAPT.

Drug delivery of memantine with carbon dots for Alzheimer's disease: blood-brain barrier penetration and inhibition of tau aggregation.

Neurofibrillary tangle, composed of aggregated tau protein, is a pathological hallmark of Alzheimer's disease (AD). The inhibition of tau aggregation is therefore an important direction for AD drug discovery. In this work, we explored the efficacy of two types of carbon dots in targeting tau aggregation, as versatile nano-carriers for the development of carbon dots (CDs)-based AD therapy.

The costs of improving health emergency preparedness: A systematic review and analysis of multi-country studies.

Background: Investing in health emergency preparedness is critical to the safety, welfare and stability of communities and countries worldwide. Despite the global push to increase investments, questions remain around how much should be spent and what to focus on. We conducted a systematic review and analysis of studies that costed improvements to health emergency preparedness to help to answer these questions.

Nanomolar, Noncovalent Antagonism of Hedgehog Cholesterolysis: Exception to the "Irreversibility Rule" for Protein Autoprocessing Inhibition.

Hedgehog (Hh) signaling ligands undergo carboxy terminal sterylation through specialized autoprocessing, called cholesterolysis. Sterylation is brought about intramolecularly in a single turnover by an adjacent enzymatic domain, called HhC, which is found in precursor Hh proteins only. Previous attempts to identify antagonists of the intramolecular activity of HhC have yielded inhibitors that bind HhC irreversibly through covalent mechanisms, as is common for protein autoprocessing inhibitors.

Effects of Aβ-derived peptide fragments on fibrillogenesis of Aβ.

Amyloid β (Aβ) peptide aggregation plays a central role in Alzheimer's disease (AD) etiology. AD drug candidates have included small molecules or peptides directed towards inhibition of Aβ fibrillogenesis. Although some Aβ-derived peptide fragments suppress Aβ fibril growth, comprehensive analysis of inhibitory potencies of peptide fragments along the whole Aβ sequence has not been reported.

Lessons Learned From a Large Cross-Border Field Simulation Exercise to Strengthen Emergency Preparedness in East Africa, 2019.

Field simulation exercises (FSXs) require substantial time, resources, and organizational experience to plan and implement and are less commonly undertaken than drills or tabletop exercises. Despite this, FSXs provide an opportunity to test the full scope of operational capacities, including coordination across sectors. From June 11 to 14, 2019, the East African Community Secretariat conducted a cross-border FSX at the Namanga One Stop Border Post between the Republic of Kenya and the United Republic of Tanzania.

Operationalisation of consensual One Health roadmaps in countries for improved IHR capacities and health security.

The COVID-19 pandemic is a devastating reminder that mitigating the threat of emerging zoonotic outbreaks relies on our collective capacity to work across human health, animal health and environment sectors. Despite the critical need for shared approaches, collaborative benchmarks in the International Health Regulations (IHR) Monitoring and Evaluation Framework and more specifically the Joint External Evaluation (JEE) often reveal low levels of performance in collaborative technical areas (TAs), thus identifying a real need to work on the human-animal-environment interface to improve health security. The National Bridging Workshops (NBWs) proposed jointly by the World Organisation of Animal Health and World Health Organization (WHO) provide opportunity for national human health, animal health, environment and other relevant sectors in countries to explore the efficiency and gaps in their coordination for the management of zoonotic diseases.

Long-Range Proton Transport in Films from a Reflectin-Derived Polypeptide.

Protein- and peptide-based proton conductors have been extensively studied because of their important roles in biological processes and established potential for bioelectronic device applications. However, despite much progress, the demonstration of long-range proton transport for such materials has remained relatively rare. Herein, we fabricate, electrically interrogate, and physically characterize films from a reflectin-derived polypeptide.

Simulation exercises and after action reviews - analysis of outputs during 2016-2019 to strengthen global health emergency preparedness and response.

Background: Under the International Health Regulations (2005) [IHR (2005)] Monitoring and Evaluation Framework, after action reviews (AAR) and simulation exercises (SimEx) are two critical components which measure the functionality of a country's health emergency preparedness and response under a "real-life" event or simulated situation. The objective of this study was to describe the AAR and SimEx supported by the World Health Organization (WHO) globally in 2016-2019.

Methods: In 2016-2019, WHO supported 63 AAR and 117 SimEx, of which 42 (66.

Information Disorder Syndrome and Its Management.

Many of us may be unknowingly suffering from information disorder syndrome. It is more prevalent due to the digitized world where the information flows to every individual's phone, tablet and computer in no time. Information disorder syndrome is the sharing or developing of false information with or without the intent of harming and they are categorized as misinformation, disinformation and malinformation.

Health security capacities in the context of COVID-19 outbreak: an analysis of International Health Regulations annual report data from 182 countries.

Background: Public health measures to prevent, detect, and respond to events are essential to control public health risks, including infectious disease outbreaks, as highlighted in the International Health Regulations (IHR). In light of the outbreak of 2019 novel coronavirus disease (COVID-19), we aimed to review existing health security capacities against public health risks and events.

Methods: We used 18 indicators from the IHR State Party Annual Reporting (SPAR) tool and associated data from national SPAR reports to develop five indices: (1) prevent, (2) detect, (3) respond, (4) enabling function, and (5) operational readiness.

Joint external evaluation of the International Health Regulation (2005) capacities: current status and lessons learnt in the WHO African region.

The International Health Regulations (IHR, 2005) are an essential vehicle for addressing global health security. Here, we report the IHR capacities in the WHO African from independent joint external evaluation (JEE). The JEE is a voluntary component of the IHR monitoring and evaluation framework.

Membrane Pore Formation by Peptides Studied by Fluorescence Techniques.

Pore formation in cellular membranes by pathogen-derived proteins is a mechanism utilized by a set of microbes to exert their cytotoxic effect. On the other hand, the host cells have developed a defense mechanism to produce antimicrobial peptides to kill the pathogens by a similar, membrane perforation mechanism. Furthermore, certain endogenous proteins or peptides kill the parent cells through membrane permeabilization.

Structure of amyloid β in lipid environment and cholesterol-dependent membrane pore formation.

The amyloid β (Aβ) peptide and its shorter variants, including a highly cytotoxic Aβ peptide, exert their neurotoxic effect during Alzheimer's disease by various mechanisms, including cellular membrane permeabilization. The intrinsic polymorphism of Aβ has prevented the identification of the molecular basis of Aβ pore formation by direct structural methods, and computational studies have led to highly divergent pore models. Here, we have employed a set of biophysical techniques to directly monitor Ca-transporting Aβ pores in lipid membranes, to quantitatively characterize pore formation, and to identify the key structural features of the pore.

Development of a Costed National Action Plan for Health Security in Pakistan: Lessons Learned.

In order to assess progress toward achieving compliance with the International Health Regulations (2005), member states may voluntarily request a Joint External Evaluation (JEE). Pakistan was the first country in the WHO Eastern Mediterranean Region to volunteer for and complete a JEE to establish the baseline of the country's public health capacity across multiple sectors covering 19 technical areas. It subsequently developed a post-JEE costed National Action Plan for Health Security (NAPHS).
