ABSTRACT

Background: The significant health development achieved in Palestine last decades has been lost, in Gaza particularly. This requires fundamental health system reform and rebuilding, including health workforces. Strengthening health workforces involves essential elements: leadership, finance, policy, education, partnership, and management. The current unprecedented catastrophe in Gaza and overall instability in Palestine show the utmost necessity for rethinking and reforming all pillars of the already collapsed health system, including the workforce. Health Workforce Accreditation and Regulation (HWAR) standardizes healthcare evaluations, representing a critical research area in Palestine due to limited existing knowledge. Objective: This study aims to enhance understanding of the HWAR in Palestine, and identify gaps and weaknesses, thereby enhancing the HWAR's development and optimization. Methods: This qualitative study used an inductive approach to explore the landscape of HWAR. Data were collected from October to November 2019, when 22 semi-structured in-depth interviews - were conducted with experts, academics, leaders, and policymakers purposely selected from government, academia, and non-governmental organization sectors. Data analysis, namely, thematic and ground theory, was performed using Excel and MS programs. Findings: The study revealed an absence of transparent governance and ineffective communication within HWAR systems. National policies and guidelines are problematic, with HWAR mechanisms fractured and needing reform. Licensing for healthcare workers hinges on local education, while monitoring and evaluation of HWAR are deficient. Some institutions adhere to HWAR standards, yet widespread updates and applications are necessary. Coordination among educational, accreditation, and practice sectors is non-systematic. Adequate human resources exist, but we need to improve HWAR management. Operational and political challenges limit HWAR, leading to a focus on immediate responses over sustainable system integration. Conclusion: Boosting HWAR is critical for Palestine, especially after the ongoing conflict and humanitarian crisis that led to the dysfunction of the entire health system facilities. A collaborative strategy across sectors is needed to improve governance and outcomes. It is essential to foster strategic dialogue among academia, regulatory entities, and healthcare providers to enhance the HWAR system. Further study on HWAR's effectiveness is recommended.

ABSTRACT

BACKGROUND: Fully endoscopic or endoscope-controlled approaches are essentially keyhole approaches in which rigid endoscopes are the sole visualization tools used during the whole procedure. At the early attempts of endoscope-assisted cranial surgery, it was noted that rigid endoscopes enabled overcoming the problem of suboptimal visualization when small exposures are used. The technical specifications and design of the currently available rigid endoscopes are associated with a group of unique features that define the endoscopic view and lay the basis for its superiority over the microscopic view during brain surgery. Fully endoscopic resection of intraparenchymal brain tumors is a minimally invasive approach that is not routinely practiced by neurosurgeons, with a few major series published so far. Unfamiliarity with the technique, steep learning curve, and concerns about inadequate exposure and decreased visibility may explain this fact. The majority of the purely endoscopic resections for intraparenchymal brain lesions are performed nowadays through tubular retractor systems. In very limited instances, however, the fully endoscopic technique is performed without tubular retractors. In this chapter, we elaborate on the surgical technique and nuances of the fully endoscopic nontubular retractor approach for intraaxial tumors. METHODS: From a prospective database of endoscopic procedures maintained by the senior author, clinical data, imaging studies, and operative charts and videos of cases undergoing fully endoscopic excision for intraaxial brain tumors were retrieved and analyzed. The pertinent literature was also reviewed. RESULTS: The surgical technique of the fully endoscopic nontubular retractor approach for intraaxial tumors was formulated. CONCLUSION: The endoscopic technique has many advantages over the conventional procedures. In our hands, the technique has proven to be feasible, efficient, and minimally invasive with excellent results.

ABSTRACT

Obesity-related joint pain is a common and debilitating condition that significantly impacts the quality of life, primarily due to the excess weight straining the joints. This results in inflammation and degeneration, which can cause pain, stiffness, and difficulty moving. We aimed to comprehensively review the literature discussing surgical interventions for obesity-related joint pain. We searched across databases (PubMed, Scopus, and Cochrane Library) to identify studies published between 2000 and 2023 that assessed surgical interventions for obesity-related joint pain. This review highlights the complex interplay of mechanical, inflammatory, and metabolic factors contributing to joint pain in obese individuals, highlighting both surgical and non-surgical interventions. Non-surgical interventions include weight loss, exercise, physical therapy, and medications. Surgical interventions include bariatric surgery and joint replacement surgery. Bariatric surgery significantly reduces body weight and improves the quality of life outcomes; however, multiple studies have found no improvement or worsening of joint pain post-surgery. Total joint arthroplasty has demonstrated good improvement in pain and function outcomes based on recent meta-analyses, although risks of complications are higher in obese patients. The treatment choice for obesity-related joint pain depends on the individual patient's circumstances. Non-surgical interventions are usually the first line of treatment. However, if these interventions are not effective, surgical interventions may be an option.

ABSTRACT

Global health governance is a strategic priority for the World Health Organization (WHO), and the public health surveillance system (PHSS) is a fundamental element of the global health governance structure to timely identify emerging diseases and guide global public health decisions and actions. This analysis explores the overall landscape of global health governance, with a specific focus on the PHSS to understand whether the existing governance landscape facilitates or undermines the WHO's ability to formulate and implement global health policies and initiatives. To achieve this, the existing evidence was reviewed, and synthesized with the experts' perspectives. It is reported that fragmentation is the main drawback of the global health governance landscape, necessitating reorganization and restructuring. The disintegration of PHSS at the global, regional and local levels is associated with a lack of leadership, misalignment with global health priorities, imbalance in coverage of surveillance systems, inadequate innovative technology and digitalization, and fragmented data and information systems. The fragmentation and disintegration of global health governance undermine the effectiveness of the WHO's global health strategic directions and programmes and hinder its ability to govern and guide the global, regional and national public health emergency response. Strategic rethinking of the WHO's governance is essential because strong governance and leadership lead to a robust, aligned and effective PHSS.

ABSTRACT

One of the most common inborn errors in fatty acid ß oxidation (FAO) is a very long-chain acyl-coenzyme A dehydrogenase (VLCAD) deficiency. It is autosomal recessive. The enzyme used in the first phase of FAO is VLCAD. The enzyme is responsible for ß oxidation spiral pathway's initial step, the dehydrogenation process of long-chain fatty acyl-CoA. The phenotypes include hypoglycemia, hepatomegaly, cardiomyopathy, and occasionally abrupt mortality. Most VLCAD deficiencies in newborns are now detected during the neonatal period due to the development of newborn screening programs. Mitochondrial DNA depletion syndromes (MTDPS) are one of the rarest metabolic disorders. It is an autosomal recessive disease caused by defects in genes necessary for the maintenance of mitochondrial DNA (mtDNA). One of these FBXL4 (F-box and leucine-rich repeat protein 4) variants causes encephalomyopathic mtDNA depletion syndrome 13 (MTDPS13), which presents as a failure to thrive, severe global developmental delay, hypotonia, early infantile onset of encephalopathy, and lactic acidosis. We report here the case of a Saudi infant born to consanguineous parents who presented to us with severe failure to thrive, profound neurodevelopmental delays, and facial dysmorphic features. Whole-exome sequencing (WES) showed the infants had MTDPS13. The FBXL4 variant c.1698A > G p. (Ile566Met) has previously been described as a disease that causes developmental delay and lactic acidosis, and another variant has also been detected in the patient. The ACADVL variant c.134C > A p. (Ser45*) has previously been described to cause VLCAD deficiency. A comprehensive literature review showed our patient to be the first case of MTDPS13 and VLCAD reported to date worldwide.

ABSTRACT

Background: Meningiomas are mostly benign and slow-growing neoplasms of the central nervous system. Spinal meningiomas account for up to 45% of all intradural spinal tumors in adults and up to 25%-45% of all spinal tumors. Spinal extradural meningiomas are rare and may be easily confused with malignant neoplasms. Case description: A 24-year-old woman was presented to our hospital with paraplegia and loss of sensation in the T7 dermatome and lower body. MRI findings showed T6-T7 right-sided intradural extramedullary and extradural lesion, measuring 1.4 cm × 1.5 cm × 3 cm, extending to the right foramen, compressing the spinal cord, and displacing it to the left. Hyperintense lesion on T2 and hypointense lesion on T1 were observed. The patient reported improvement after surgery and during follow-up. We recommend maximizing the decompression during surgery to achieve better clinical outcome. Extradural meningiomas represent 5% of all meningiomas; therefore, having an intradural on top of extradural meningioma with extraforaminal extensions makes this a unique and rare case. Conclusion: Meningiomas can be easily missed in diagnosis depending on imaging and the pathognomonic pattern it represents, which can mimic other pathologies, such as schwannomas. Therefore, surgeons should always suspect their patient having a meningioma even if the pattern is not typical. Moreover, preoperative preparation, such as navigation and defect closure, must be taken in case it turns out be a meningioma instead of the presumed pathology.

ABSTRACT

The Revised National Community Health Services Policy (2016-2021) (RNCHSP) and its programme implementation, the Liberian National Community Health Assistant Programme (NCHAP), exhibit a critical gender imbalance among the Community Health Assistants (CHAs) as only 17% are women. This study was designed to assess the gender responsiveness of the RNCHSP and its programme implementation in five counties across Liberia to identify opportunities to improve gender equity in the programme. Using qualitative methods, 16 semi-structured interviews were conducted with policymakers and 32 with CHAs, other members of the community health workforce and community members. The study found that despite the Government of Liberia's intention to prioritize women in the recruitment and selection of CHAs, the planning and implementation of the RNCHSP were not gender responsive. While the role of community structures, such as Community Health Committees, in the nomination and selection of CHAs is central to community ownership of the programme, unfavourable gender norms influenced women's nomination to become CHAs. Cultural, social and religious perceptions and practices of gender created inequitable expectations that negatively influenced the recruitment of women CHAs. In particular, the education requirement for CHAs posed a significant barrier to women's nomination and selection as CHAs, due to disparities in access to education for girls in Liberia. The inequitable gender balance of CHAs has impacted the accessibility, acceptability and affordability of community healthcare services, particularly among women. Strengthening the gender responsiveness within the RNCHSP and its programme implementation is key to fostering gender equity among the health workforce and strengthening a key pillar of the health system. Employing gender responsive policies and programme will likely increase the effectiveness of community healthcare services.

ABSTRACT

BACKGROUND: The health research system (HRS) is an important national priority that requires a systematic and functional approach. Evaluating the HRS of Iran as a developing country and identifying its challenges reveals the stewardship-related role in how the whole system is operating well. This study aims to assess the HRS in terms of stewardship functions and highlight the enhancement points. METHODS: This study was carried out between March 2020 and April 2021 using a systematic review and meta-synthesis of evidence to examine the Iranian HRS stewardship challenges and interview 32 stakeholders, using a critical case sampling and snowballing approach which included both semi-structured and in-depth interviews. The interviewees were selected based on criteria covering policy-makers, managers, research bodies and nongovernmental organizations (NGOs) in health research-related fields like higher education, research, technology, innovation and science. All data were analysed using content analysis to determine eight main groups of findings under three levels: macro, meso, and micro. RESULTS: Analysis of the findings identified eight main themes. The most critical challenges were the lack of an integrated leadership model and a shared vision among different HRS stakeholders. Their scope and activities were often contradictory, and their role was not clarified in a predetermined big picture. The other challenges were legislation, priority-setting, monitoring and evaluation, networking, and using evidence as a decision support base. CONCLUSIONS: Stewardship functions are not appropriately performed and are considered the root causes of many other HRS challenges in Iran. Formulating a clear shared vision and a work scope for HRS actors is critical, along with integrating all efforts towards a unified strategy that assists in addressing many challenges of HRS, including developing strategic plans and future-oriented and systematic research, and evaluating performance. Policy-makers and senior managers need to embrace and use evidence, and effective networking and communication mechanisms among stakeholders need to be enhanced. An effective HRS can be achieved by redesigning the processes, regulations and rules to promote transparency and accountability within a well-organized and systematic framework.

ABSTRACT

Translating research into clinical practice is a global priority because of its potential impact on health services delivery and outcomes. Despite the ever-increasing depth and breadth of health research, most areas across the globe seem to be slow to translate relevant research evidence into clinical practice. Thus, this review sought to synthesise existing literature to elucidate the barriers and facilitators to the translation of health research into clinical practice. A systematic review of reviews approach was utilised. Review studies were identified across PubMed, Scopus, Embase, CINAHL and Web of Science databases, from their inception to 15 March 2021. Searching was updated on 30 March 2022. All retrieved articles were screened by two authors; reviews meeting the inclusion criteria were retained. Based on the review type, two validated tools were employed to ascertain their quality: A Measurement Tool to Assess Systematic Reviews-2 and International Narrative Systematic assessment. The framework synthesis method was adopted to guide the analysis and narrative synthesis of data from selected articles. Ten reviews met the inclusion criteria. The study revealed that the translation of new evidence was limited predominantly by individual-level issues and less frequently by organisational factors. Inadequate knowledge and skills of individuals to conduct, organise, utilise and appraise research literature were the primary individual-level barriers. Limited access to research evidence and lack of equipment were the key organisational challenges. To circumvent these barriers, it is critical to establish collaborations and partnerships between policy makers and health professionals at all levels and stages of the research process. The study concluded that recognising barriers and facilitators could help set key priorities that aid in translating and integrating research evidence into practice. Effective stakeholder collaboration and co-operation should improve the translation of research findings into clinical practice.

ABSTRACT

The Health Workforce Accreditation and Regulation (HWAR) is a key function of the health system and is the subject of increasing global attention. This study provides an assessment of the factors affecting the Palestinian HWAR system, identifies existing gaps and offers actionable improvement solutions. Data were collected during October and November 2019 in twenty-two semi-structured in-depth interviews conducted with experts, academics, leaders, and policymakers purposely selected from government, academia, and non-governmental organizations. The overall perceptions towards HWAR were inconsistent. The absence of a consolidated HWAR system has led to a lack of communication between actors. Environmental factors also affect HWAR in Palestine. The study highlighted the consensus on addressing further development of HWAR and the subsequent advantages of this enhancement. The current HWAR practices were found to be based on personal initiatives rather than on a systematic evidence-based approach. The need to strengthen law enforcement was raised by numerous participants. Additional challenges were identified, including the lack of knowledge exchange and salary adjustments. HWAR in Palestine needs to be strengthened on the national, institutional, and individual levels through clear and standardized operating processes. All relevant stakeholders should work together through an integrated national accreditation and regulation system.

ABSTRACT

As decolonisation awareness and activism amplifies in the mainstream masses and within academic realms across a variety of fields, the time is right to converge parallel movements to decolonise the fields of global health and evaluation by restructuring relations of dependency and domination reified through the "foreign gaze"1 or "white gaze." We conducted a review of relevant records with the following inclusion criteria-they define or advocate for the decolonisation of global health evaluation or explicate methods, policies or interventions to decolonise global health evaluation published by advocates of the decolonisation movement from both fields. These records were derived following a systematic article search by the lead autthor on Google, Google Scholar, NewsBank, and PubMed using the following keywords: "decolonising" and "global health," "evaluation," or "global health evaluation" replicating a digital search strategy utilized by scoping reviews across a variety of topics. Because the topic of interest is nascent and still emerging, the date range was not restricted. The lead author screened abstracts retrieved from the search. In total, 57 records, ranging in publication date from 1994 to 2020, were selected and charted for this review. We reviewed these records to identify socio-ecological factors that influence the decolonisation of global health evaluation, such as decolonising minds; reorienting funders and reforming funding mechanisms; and investing in sustainable capacity exchange. In doing so, we reflected on our positionality as well as our internalisation and potential reinforcement of colonial relations in the process of reporting our results. In the context of turmoil and transition due to the COVID-19 pandemic, our scoping review offers a starting point to embark on a journey first to transform and decolonise global health evaluation and then to achieve the greater goal of equity and justice.

ABSTRACT

Objectives: Over the last 2 decades, the World Health Organization (WHO) has proposed a global strategy and initiatives to establish a Health Research System (HRS) focusing on Health Research Quality and Standardization (HRQS), Health Research Knowledge Transfer and Dissemination (HRKTD), and Health Research Translation and Utilization into Health Care Decisions and Policies (HRTUDP). Despite the increase in health research productivity over the past several decades, HRS Capacity (HRSC) in Palestine and in the Middle East and North Africa (MENA) region has rarely been objectively evaluated. This study aims at eliciting the perceptions of HRS performers in Palestine in order to understand the status of HRSC, identify gaps, and generate policies and solutions capable of strengthening HRSC in Palestine. Methods: Key informants from three sectors, namely government, academia, and local and international organizations, were selected purposively based on different sampling methods: criterion, critical case, snowball, and homogeneous sampling. Fifty-two in-depth interviews with key informants and a total of fifty-two individuals, participating in six focus groups, were conducted by the principal investigator in Palestine. Data were analyzed by using MAXQDA 12. Results: The overall pattern of the Palestinian HRSC is relatively weak. The key findings revealed that while HR productivity in Palestine is improving, HRQS is at an average level and quality guidelines are not followed due to paucity of understanding, policies, and resources. HRKTD is a central challenge with both a dearth of conceptualization of translational science and inadequate implementation. The factors related to inadequate HRKTD include lack of awareness on the part of the researchers, inadequate regulatory frameworks and mechanisms for both communication and collaboration between and among researchers and policy-makers and clinicians, and lack of availability of, and credibility in, systematized and reliable HR data. Despite the limited knowledge translation, in general, HRTUDP is not considered an essential decision-making methodology mainly due to the lack of interface between knowledge producers (researchers) and users (policymakers), understanding level, HR credibility and availability of applied research, and governance, resources, and political fluctuations. Recommendations to strengthen HRS in Palestine include: a consolidated research regulatory framework and an effective capacity strengthening strategy overseen by Palestinian authorities; the promotion of HRQS and concepts and practices of translational science; and, most importantly, the use of findings for evidence-based policies and practice. Conclusion: Strengthening HRSC is both an imperative step and an opportunity to improve the Palestinian health system and ensure it is based on research evidence and knowledge. Building a successful HRS characterized by capacities of high-quality research and well-disseminated and translated knowledge is a prerequisite to effective health systems and services. This can be achieved by political commitment to support such strengthening, a consolidated leadership and governance structure, and a strong operational capacity strengthening strategy.

ABSTRACT

Technological innovation has a significant role in improving health systems (HSs) and achieving universal health coverage (UHC). The World Health Organization (WHO) has declared resolutions on Health Technology Assessment (HTA) and other global organizations emphasized on HTA systems to achieve the Sustainable Development Goals (SDGs). HTA is a modern multidisciplinary decision-making framework linking knowledge and policymaking by assessing the medical, social, economic, organizational, and ethical effects, and/or impacts within health and social systems. The research significance lies in the growing need for HTA at these moments than ever as it is seen as an essential development approach to tackle the current global challenges and pandemics, particularly in developing countries. The research aims to comprehensively evaluate and understand HTA systems concerning the level of knowledge about HTA, current HTA structure, practices, application, capacity, gaps, and solutions. The project starts in January 2021 and ends in January 2022 and will be carried out in seven countries: Canada, Switzerland, Brazil, Lebanon, Jordan, Palestine, and Tanzania. A mixed-methods, quantitative and qualitative, along with a literature review will be applied. In each country, ten HTA-associated institutions will complete an adapted electronic survey, developed by the WHO, and ten key-informants selected purposively from the government, academia, NGOs, and private sectors to participate in ten individual in-depth interviews. One government representative from each country will participate in one expanded inter-country workshop. Excel, IBM Statistical Package for the Social Sciences (SPSS), and MAXQDA software programs will be used for data management and analysis. The research will form cutting-edge evidence not only for the seven countries, but also for the global, regional, and national endeavors with regards to opening a room for HTA best application and optimization. It will reveal lessons learned, determine gaps, and build a well-enabled and institutionalized HTA for better UHC, health systems, and multi-sectoral development.

ABSTRACT

The COVID-19 pandemic is considerably the biggest global health challenge of this modern era. Spreading across all regions of the world, this corona virus disease has disrupted even some of the most advanced economies and healthcare systems. With an increasing global death toll and no near end in sight, questions on the efficacy of global response mechanisms, including the role and relevancy of global health institutions, have emerged. Using a reflexive content analytic approach, this study sheds light on some of these questions, underscoring the disconnect between science, policymaking, and society. Global health funding approaches; politicization of the pandemic, including political blame gaming; mistrust of government and other institutions; and a lack of robust accountability measures are some of the pandemic response obstacles. However, COVID-19 has also presented an opportunity for a collaboration that may potentially solidify global solidarity. A pandemic response built on strategic global health diplomacy, vaccine diplomacy, and science diplomacy can spur both political and economic benefits, advancing development, health security, and justice. The virus thrives and flourishes in face of political divisions and lack of cooperation. While the current global crisis has exacerbated the existing social injustices in societies, national unity and global solidarity is essential to winning the fight against the COVID-19 pandemic.

ABSTRACT

BACKGROUND: Anterior cruciate ligament injuries are commonly seen in orthopedic surgery practice. Although anterior cruciate ligament reconstruction (ACLR) has come a long way, the causes of failure have yet to be fully understood. OBJECTIVE: The aim of this study was to investigate whether or not the intraoperative 4-strand hamstring autograft diameter does in fact influence the failure rates of ACLR. METHODS: Retrospective intraoperative data were collected from ACLR patients from the only tertiary center available in Kuwait. Patients who underwent ACLR from 2012 to 2018 for isolated ACL injuries were included in this study, allowing for a 24 month follow-up period The cohorts were categorized into 3 groups: patients with graft size≤8mm, 2, patients with graft sizes≥8mm with 4-strands and patients with graft sizes≥8mm with 4-strands or more. ANOVA analysis was applied to address group differences between mean graft size and strand numbers and subsequently the failure rates for each group. In addition, the Mann-Whitney U test was used to investigate the relationship between revision and initial ACL graft size. RESULTS: Out of the 711 out of 782 patients were included in this study. Only 42.6% of the patients did not need more than 4-strands to achieve an 8mm sized autograft. The patients who had autografts≤8mm in this study accounted for 17.1% of the population. About 7.2% of these patients required revision surgery. Patients with a 4-strand autograft size that was less than 8mm were 7.2 times more at risk for ACLR failure (RR=7.2, 95% CI: 6.02; 8.35, p=0.007). CONCLUSIONS: There is a significant correlation between 4-strand autograft diameter size and the need for ACLR revision surgery. LEVEL OF EVIDENCE: IV case series.

ABSTRACT

Hydraulic fracturing using water-soluble polymers has been extensively used to enhance the productivity of oil and gas wells. However, the production enhancement can be significantly impaired due to polymer residue generated within the proppant pack in the created fractures. This work describes an approach to establish a suitable fracturing fluid cleanup process by characterizing broken polymer residues generated from the use of different gel breaker types. Commonly used gel breakers such as inorganic oxidizers (bromate and persulfate salts), specific enzymes, and acids were evaluated in this work. The influence of each gel breaker was examined using High-Pressure/High-Temperature (HP/HT) rheometer, aging cells, zeta potential, Gel Permeation Chromatography (GPC), and Environmental Scanning Electron Microscope/Energy Dispersive X-ray Spectroscopy (ESEM/EDS). Experiments were performed on a carboxymethylhydroxypropyl guar (CMHPG) fracturing fluid at temperatures up to 300 °F. The developed GPC methodology showed that the size of the broken polymer chains was mainly dependent on the type of gel breakers used. Moreover, laboratory tests have revealed that some gel breakers may negatively influence the performance of polymeric clay stabilizers. Additionally, this work showed damaging precipitations that can be generated due to the interactions of gel breakers with H2S.

ABSTRACT

BACKGROUND: The World Health Organization has proposed a global strategy to build a robust Health Research System Resources and Infrastructural Capacity (HRSRIC). Despite the growing research productivity, HRSRIC in Palestine has rarely been investigated. AIMS: To analyse perceptions of health research system performers to understand the status of HRSRIC, identify its gaps, and propose policy solutions to strengthen HRSRIC. METHODS: This qualitative study targeted 3 health sectors: government, academia, and local and international organizations. Fifty-two in-depth interviews and 6 focus group discussions were conducted with key informants who were selected purposively. Data were analysed using MAXQDA 12. RESULTS: Despite the availability of competent personnel, the overall HRSRIC, such as human and financial resources, and facilities, forms a central challenge. HR financing is limited, unsustainable, and flows from external and individual sources. The public and private funds are largely in shortage with resources misallocation and donors' conditionality. HR quality is moderate while knowledge transfer and translation are not well conceptualized and inappropriately performed. Lack of governance, coordination, HRSRIC strategy, resource allocation, systematic and reliable data, evidence-informed culture, and environmental impacts are the main common gaps. CONCLUSIONS: The overall status of HRSRIC in Palestine is still lacking and major challenges persist where the pace of strengthening efforts is steady. There is an emphasis that strengthening HRSRIC is an imperative step and real investment opportunity for building a successful health research system. Political commitment, consolidated leadership structure, operational capacity building strengthening strategy, resources mobilization, and sovereignty are key requirements.
