Exploring the coping strategies of women after self-immolation: A qualitative study

BACKGROUND

Women confront a slew of issues following self-immolation, and it is crucial to examine how women react after self-immolation and live with their scars. Therefore, this study was conducted with the aim of exploring the coping strategies of Kurdish women following self-immolation using a qualitative methodology.

METHODS

The conventional content analysis approach was used in this qualitative investigation. Semi-structured face-to-face and phone interviews were conducted with 26 Kurdish women who had self-immolated and were chosen using purposeful sampling and snowballing for this study. To reinforce the research, Guba and Lincoln's trustworthiness criteria were fulfilled.

RESULTS

The data analysis yielded 2 categories, 11 subcategories, and 85 initial codes. Positive coping is one of the categories and subcategories (spirituality, rebuilding their body, psychological rehabilitation, hiding the scars, restoring self-confidence, changing the lifestyle, forming a new life) 2- Negative coping (separation from society, neglecting the body and mind, violence and aggression, staying in the past).

CONCLUSION

Using the capacity of religious organizations to help victims of self-immolation, providing appropriate conditions and facilities to heal the scars caused by self-immolation, and facilitating access to counseling services can provide the conditions for women to better adapt after self-immolation.

Gefitinib derivatives and drug-resistance: A perspective from molecular dynamics simulations

Epidermal-growth factor receptor (EGFR) is a transmembrane tyrosine kinase (TK) with a significant role in cell survival. EGFR is upregulated in various cancer cells and known as a druggable target. Gefitinib is a first-line TK inhibitor used against metastatic non-small cell lung cancer (NSCLC). Despite initial clinical response, a conserved therapeutic effect could not be achieved due to the occurrence of resistance mechanisms. Point mutations in EGFR genes are one of the major causes of rendered tumor sensitivity. To aid in the development of more efficient TKIs, chemical structures of prevailing drugs and their target binding patterns are very important. The aim of the present study was to propose synthetically-accessible gefitinib congeners with enhanced binding fitness to clinically frequent EGFR mutants. Docking simulations of intended molecules identified 1-(4-(3-chloro-4-fluorophenylamino)-7-methoxyquinazolin-6-yl)-3-(oxazolidin-2-ylmethyl) thiourea (23) as a top-binder structure inside G719S, T790 M, L858R and T790 M/L858R-EGFR active sites. Superior docked complexes were subjected to the entire 400 ns molecular dynamics (MD) simulations. Analysis of data revealed the stability of mutant enzymes upon binding to molecule 23. All mutant complexes with the exception of a T790 M/L858R-EGFR, were majorly stabilized through cooperative hydrophobic contacts. Pairwise analysis of H-bonds proved Met793 as the conserved residue with stable H-bond participations as hydrogen bond donor (Frequency 63-96%). Amino acid decomposition analysis confirmed the probable role of Met793 in complex stabilization. Estimated binding free energies indicated the proper accommodation of molecule 23 inside target active sites. Pairwise energy decompositions of stable binding modes revealed the energetic contribution of key residues. Although wet lab experiments are required to unravel the mechanistic details of mEGFR inhibition, MD results provide structural basis for those events that are difficult to address experimentally. The outputs of the current study may assist to design small molecules with high potency to mEGFRs.

Coxiella burnetii Pathogenesis: Emphasizing the Role of the Autophagic Pathway

Coxiella burnetii (C. burnetii), the etiological agent of the Q fever disease, ranks among the most sporadic and persistent global public health concerns. Ruminants are the principal source of human infections and diseases present in both acute and chronic forms. This bacterium is an intracellular pathogen that can survive and reproduce under acidic (pH 4 to 5) and harsh circumstances that contain Coxiella-containing vacuoles. By undermining the autophagy defense system of the host cell, C. burnetii is able to take advantage of the autophagy pathway, which allows it to improve the movement of nutrients and the membrane, thereby extending the vacuole of the reproducing bacteria. For this method to work, it requires the participation of many bacterial effector proteins. In addition, the precise and prompt identification of the causative agent of an acute disease has the potential to delay the onset of its chronic form. Moreover, to make accurate and rapid diagnoses, it is necessary to create diagnostic devices. This review summarizes the most recent research on the epidemiology, pathogenesis, and diagnosis approaches of C. burnetii. This study also explored the complicated relationships between C. burnetii and the autophagic pathway, which are essential for intracellular reproduction and survival in host cells for the infection to be effective.

Tobacco harm reduction in Afghanistan: a recipe for improving smokers' health

Tobacco Harm Reduction (THR) offers a promising approach to addressing the significant burden of smoking in Afghanistan. Over three million Afghans smoke daily, making it a leading cause of preventable deaths in the country. While the previous Afghan government implemented various tobacco cessation policies and strategies, these measures were only partially effective in reducing the number of smokers or smoking-related deaths. In 2021, community-based initiatives in Kabul and Herat started advocating for Tobacco Harm Reduction (THR) as a novel, realistic, and practical approach proven to promote smoking abstinence and minimize tobacco harm. However, implementing THR strategies in Afghanistan faces numerous challenges, including a lack of governmental support, funding issues, unfavorable market conditions, the high cost-effectiveness of THR products, and misconceptions about these products. To effectively promote THR in Afghanistan and overcome these challenges, it will be necessary to implement THR policies that support THR products for smokers, regulate the market for these products, produce them locally with healthcare professional oversight, conduct more engaging advocacy campaigns, and secure domestic sponsors.

Strengthening rural surgery in the Philippines: Essential in achieving universal health care

The Lancet Commission on Global Surgery (LCoGS) launched Global Surgery 2030 to address the surgical services inequities with a bias toward low‐income and middle‐income countries like the Philippines. The same inequity is observed particularly when it comes to the urban‐rural divide. With more than half of the population living in rural areas, access to surgery becomes a major challenge that further impedes the much‐needed health of an economically productive workforce. The Universal Health Care [UHC] Act (RA 11332) of 2019 ensures that all Filipinos have access to quality, cost‐effective, promotive, preventive, curative, rehabilitative, and palliative health services without causing a financial burden. Recognizing the provision of essential surgery, in the context of primary healthcare is important. It should be accessible, continuous, comprehensive, and coordinated at the time of need – parallel to the principle of primary health care. Driven by this concept and experiences, the authors conceptualized and presented the Philippine Rural Surgery model for future development and implementation. This is envisioned to provide essential surgery among local rural primary health care settings that is universal, accessible, cost‐effective and safe. As this is still new in the Philippines, we proposed tenets and recommendations based on WHO Health System Strengthening building blocks to guide stakeholders in creating formal plans towards institutionalization under the principles of UHC. Such access to surgical service in the context of a unique socio‐demography of the Philippines would be essential in attaining the parameters and provisions set by the UHC Act.

COVID-19 AND INSECURITY IN NORTHERN NIGERIA

Northern Nigeria is currently facing a twin crisis of both COVID-19 and insecurity. They have made it difficult for the people to follow government containment efforts to control the pandemic and also have impacted on the socioeconomic and health aspects of the society. We have discussed on the impact of insecurity amid COVID-19 in Northern Nigeria. It is opined that if the insecurity in Northern Nigeria is not tackled, it will expose the region to more escalation of cases and deaths. Thus, it is recommended that proactive steps should be implemented by all stakeholders concerned to tackle insecurity, particularly the government to revive the security architecture, provide an environment for training and retraining of all security personnel and enhancing intelligence gathering to pave the way for resolving this issue.

High-intensity interval training improves fat oxidation during submaximal exercise in active young men

This study aimed to examine the effects of four-weeks high-intensity interval training (HIIT) on fat oxidation responses during submaximal exercise in active young men. For this purpose, 20 active young men (who participated in the exercise three times per week) were divided into two groups, including a training group (age: 19.3±0.48 years, V̇O2peak 2.9±0.35 l/min, n=10) and a control group (age: 19.7±0.67 years, V̇O2peak 2.7±0.26 l/min, n=10). The training group performed high-intensity interval training for three sessions per week. Specifically, each session included 8-11 intensive cycling efforts comprising of 60 s duration. A 75 s low pedalling rate (30 W) was used as an active recovery between the intervals. Furthermore, a V̇O2peak test was performed prior to, at the end of two weeks and after the training period. Also, a 60 min constant cycling protocol was performed at ~60% V̇O2peak, in addition to the V̇O2peak test, before and after the training protocol. To assess plasma free fatty acids and glucose, blood samples were taken during a 60-min aerobic exercise prior to and following the training period. An increase (17.8%) in V̇O2peak was observed for the HIIT group after the training period compared to the control group (P<0.05). The HIIT group performed the 60 min sub-maximal exercise test at a lower percentage of V̇O2peak, and decreases in the respiratory exchange ratio were greater in the HIIT group than in the control group (P<0.05). Compared to the pre-test values and control group results, the HIIT group used less carbohydrate and more lipid oxidation during submaximal exercise (P<0.05). The present study’s results indicate that short-term low volume HIIT can increase aerobic capacity and fat oxidation during submaximal exercise.

Current Status and Structure Activity Relationship of Privileged Azoles as Antifungal Agents (2016-2020)

Fungal infections have major contribution to the infectious related deaths in recent century. The issue has gotten worse with the advent of immunity impairing conditions such as HIV epidemic. Eukaryote nature of fungal pathogens leads to harder eradication than bacterial infections. Given the importance of the problem, considerable efforts have been put on the synthesis and biological assessment of azole-based chemical scaffolds and their bioisosteres. The emergence of validated macromolecular targets within different fungal species inspires structure-based drug design strategies toward diverse azole-based agents. Despite of advantageous features, emergence of drug-resistant fungal species restrict the applicability of current azoles as the first-line antifungal agents. Consequently, it appears advisable to elucidate SARs and chemical biodiversity within antifungal azoles. Current contribution was devoted to a brief look at clinically applied drugs, structure-based classification of azole antifungals and their structure activity relationships (SARs). Reviewed molecules belong to the antifungal structures that were reported throughout 2016-2020.

COVID-19 denial in Turkmenistan veiling the real situation

Coronavirus disease 2019 (COVID-19) emerged in late 2019, with the first case identified in Wuhan City, Hubei Province, China, on 12 December 2019. In order to perceive the comprehensive impact of this pandemic, we have to know that misinformation and denials about COVID-19 have surely exacerbated its diffusion and hindered the response against it. Turkmenistan remains one of the very few countries in the world that lacks reports about emerging cases of the novel coronavirus. Turkmen authorities claim that they have adopted all attainable measures required in order to combat the virus, asserting that COVID-19 has yet to reach their country. Despite the government's reported absence of COVID-19 in the country, rumors, media reports and independent sources suggest the spread of the pandemic in Turkmenistan. By mid-June 2020, the outbreak was referred to as being serious with patients suffering extreme health risks, and following its state of disrepair and unethical practices, many of those anticipated to be COVID-19 infected tend to suffer at home, discouraging any interaction with the healthcare system. The civil society in Turkmenistan, for the time being, takes full part of the government's duty in the process of informing and educating the public regarding the COVID-19 pandemic, and endeavors to keep the government and WHO accountable for behaving in such repressive ways that could lead to rather preventable loss of human life in Turkmenistan. Yet, efforts hang fire before unveiling the real situation, and Turkmenistan's government owning up to the negations and roaming speculations, not only regarding the coronavirus crisis, but every public-related issue itself.

The daunting task of fighting HIV in Afghanistan: Current evidence and future recommendations

The human immunodeficiency virus (HIV), like any other disease, has created great worry in Afghanistan. The country's slew of issues has paved the way for HIV to spread and go unchecked. International groups have banded together to stop the virus's spread since the first case was confirmed in Afghanistan. The cumulative effects of international collaboration have aided in the reduction of cases and improved awareness. Because of their injection use, a large portion of the country's population has been classified as a vulnerable category for HIV infection. Awareness campaigns and international collaboration should be implemented to further limit the spread of HIV.

War Experience, Daily Stressors and Mental Health Among the Inter-taliban Generation Young Adults in Northern Afghanistan: A Cross-Sectional School-Based Study

OBJECTIVES

The specific objectives of the study are to examine the mental health (depression and anxiety) of the first generation of post-Taliban government and compare these measures with its preceding generation, and to assess war experience of the first generation of post-Taliban government. We also wanted to assess the daily stressors and their contribution to the mental health, and to assess mental health as a result of war experiences and daily stressors with respect to demographic measures such as sex, marital status, age, mother's age, birth order, and ethnicities.

METHODS

In a cross-sectional design, 621 high school students, were randomly selected to participate in the study to assess war experience, daily stressors, and mental health among the first generation of young adults under post-Taliban government.

RESULTS

The participants had 17.37 ± 0.9 mean years of ages, 94.8% of them were unmarried. Poor mental health was significantly associated with higher exposure to war, but not with the age of participants (P = 0.08). There was no association between war experiences and the age and ethnicity of our participants (p = 0.9, p = 0.7). Age differences were negligible for daily stressors too (P = 0.07). Daily stressors scores were higher for female than male students (P = 0.02). The majority of young adults surveyed, declared themselves in agreement with statements such as the security situation in Afghanistan makes me frustrated (56%), air pollution as a concern (41%), and not having anyone to talk about what is in their heart (28.8%). Gender differences were highly significant for mental health, as appraised by both The Hopkins Symptoms Checklist (HSCL) -depression and HSCL-anxiety. Girls presented higher rates of depression, anxiety, and daily stressors than boys, and boys presented higher rates of war experiences than girls.

CONCLUSION

War experience, daily stressors, and mental health were irrelevant with age, ethnicity and marital status. Factor such as being the first-born child of the family, higher reported war experiences, and daily stressors all negatively impact mental health. Alongside war and its direct effects, the existing socio-cultural context must be considered as a potential factor mediating the mental health of girls in Afghanistan.

Posterior First and Second Cervical Vertebrae Fusion by Screw Fixation Technique using the Modern Pre-fabricated Template Method on Cadaver Samples

Introduction

C1 lateral mass and C2 pedicular screws insertion are used for C1-C2 posterior fusion. Fluoroscopy Guided technique is routinely used for screw placement but it is associated with risk of injury to spinal cord and vertebral artery. 3D printing has developed rapidly in the fields of medicine. It is helpful in improving precise treatment and used for instrumentation in spine. We want to evaluate the accuracy of C1 lateral mass screws and C2 pedicle screws insertion by Pre-Fabricated Template made by three-dimensional (3D) printing.

Materials and methods

Five cervical samples were obtained from cadavers. Based on fine-cut CT scan 3D-images reconstructed and the path of the screws designed by special software. A template produced by 3D-printer from 3D images. After printing the templates, they were fixed on the relevant vertebra in the operation room and based on the template path, C1 lateral mass screw and C2 pedicular screws were inserted. Placement of the screws was evaluated using CT scans post-operatively.

Results

A total of 14 screws were inserted by above-mentioned method. After evaluation with CT scans none of the screws were entered in the spinal canal. Two screws had vertebral artery canal perforation with less than 50% breach. Violation was judged as noncritical and would probably not have resulted in injury to vertebral artery.

Conclusions

The accuracy of C1 lateral mass screw and C2 pedicle screw insertion is acceptable with pre-fabricated template and can provide a useful aid for screw placement.

Sex Workers Should Be Included in COVID-19 Vaccination Efforts

As the COVID-19 pandemic takes its toll on citizens across the globe, more people turn to sex work for survival. Because sex work is inherently physical and intimate, sex workers become defenseless against the virus and act as a bridge for transmitting the virus to their clients and society. Often, sex workers are the victims of violence and homelessness, and are devoid of health-care facilities, including HIV treatment, and are frequently exposed to a large number of individuals as dictated by the nature of their work. Their survival instincts would drive them to take part in their usual job to earn money, despite added health risks, to survive and feed their families. Worldwide, sex workers do not fully benefit from the COVID-19 responses, particularly in health, social, and economic aid assistance and services. Hence, it is essential to include this vulnerable population in the COVID-19 vaccination programs to halt the further spread of the virus.

Bhutan's COVID-19 Vaccination Efforts and the Evolution of COVID-19 Cases in the Aftermath

The COVID-19 pandemic is continuing to ravage countries across the world. It has displaced families and impacted economies around the world. Our fight against the pandemic is never ending, but COVID-19 vaccines offer unique promises and opportunities to win this war. As more and more vaccines are approved for use, many countries including Bhutan have started vaccinating their population against the SARS-CoV2 disease. Bhutan has fully vaccinated 61.5% of its people and 11.2% partially including children aged between 12 and 17 years. The country used many strategies to increase vaccine accessibility and availability such as government's exhaustive efforts to secure enough vaccine doses, careful preparations, use of international partners, and integration of its tradition and culture for wider vaccine acceptance. The protection from vaccines coupled with other public health measures has helped keep the number of COVID-19 cases to a manageable number without straining its health system too much. The success story is a "beacon of hope for the region" as the world looks to rebuild itself from this long exhausting fight against the COVID-19 pandemic.

Food security and COVID-19 in Afghanistan: a two-sided battlefront

Food security is a major element for the sustainability, stability and development of a country. However, despite fundamental efforts in fighting poverty, Afghanistan continues to struggle with food insecurity with a large proportion of its population living below the poverty line. With extreme climates, protracted conflict, and now COVID-19, food insecurity has become rampant and is on the rise in the country. Efforts have been reinforced to mitigate this issue, but a spate of obstacles which seems not to come to an end, has contributed to the deterioration of the situation. With the collaboration and efforts of international organizations, there remains a glimmer of hope to potentially reduce the gravity of the food insecurity in the country. This paper aims to highlight the efforts of Afghanistan in alleviating food insecurity with a focus on the impact of COVID-19 on this issue. It also presents recommendations that may help ameliorate the country’s food security status during and after the pandemic.

Accelerating Indonesian COVID-19 vaccination rollout: a critical task amid the second wave

Coronavirus disease-19 (COVID-19) has been spreading in every part of the world, putting nations at risk with its pandemic status, including Indonesia. COVID-19 vaccine has been deemed as one of the most effective interventions to date for mitigating the spread and mortality from COVID-19. Responding to the situation, the Government of Indonesia (GOI) has allocated the means necessary to procure and distribute COVID-19 vaccines; placing into consideration the unique context of the country, recently categorized as a middle-income country and archipelagic with a population over 270 million. This article aims to present the challenges associated with the distribution of COVID-19 vaccination as well as recommendations to mitigate them, to ensure a timely and effective COVID-19 vaccination program in Indonesia.

COVID-19 Vaccination Efforts: Is Afghanistan Prepared?

A country’s preparedness for a prompt and successful implementation of vaccination programs plays a pivotal role in disease control and prevention. As it stands now, Afghanistan seems to be ill-prepared to embrace a successful implementation of the COVID-19 vaccination program because of a spate of challenges. These include, but are not limited to, the insufficient number of vaccinators, a dearth of fully integrated functioning cold chain, challenging geographical barriers, cultural issues, insecurity, and protracted conflict. The COVID-19 infodemic along with vaccine mistrust in the country will lead to a pervasive public vaccine hesitancy in Afghanistan, which will present serious obstacles to the COVID-19 immunization efforts. The politicization of the Ministry of Public Health (MoPH) and the complaints of embezzlement and misuse of the pandemic aid have already eroded public trust during the pandemic. To ensure a large-scale and equitable distribution of COVID-19 vaccines, the cold chain infrastructure should be strengthened, and the immunization personnel trained. Antivaccination propaganda and misinformation should be tackled with effective communication approaches and effective community engagement, which consider culturally relevant messages appropriate to the culture and people. The allegations of corruption should be addressed to revive public trust in public health interventions, including COVID-19 vaccination.

Moderate grazing is the best measure to achieve the optimal conservation and soil resource utilization (case study: Bozdaghin rangelands, North Khorasan, Iran)

The study of the variability of physical and chemical factors of soil due to different intensities of livestock grazing can help in the management and maintenance of soil and vegetation. Accordingly, the effect of livestock grazing intensities on soil properties and vegetation in Bozdaghin rangelands of North Khorasan province was investigated. To investigate the effect of different livestock grazing intensities, Three 5-hectare plots in the study area were determined under different treatments (ungrazed (UG), moderate grazing (MG), and heavy grazing (HG)), and the effect of three grazing intensities on vegetation and soil physicochemical and erodibility properties (SPEP) was evaluated. The soil sampling process was performed at depths of 0-15, 15-30 cm and SPEP including soil saturation moisture (SSM), soil texture (percentage of clay, sand, and silt), absorbable potassium (K), electrical conductivity (EC), soil organic matter (SOM), absorbable phosphorus (P), acidity (pH), and bulk density were evaluated, and Soil Erodibility Index (SEI) was calculated by implementing the modified clay ratio relation. To assess the impact of various grazing intensities on all measured characteristics, multivariate analysis of variance (MANOVA) and Duncan tests were utilized to compare the means and their grouping. The results showed that HG compared to MG causes worrying consequences in the first soil depth. Also with increasing grazing intensity, plant production percentage (P < 0.05) and vegetation density (P < 0.01) decreased, and the amount of bare soil (P < 0.01) increased. Also, with increasing grazing intensity, the amount of pH, EC, clay, saturated moisture, and N decreased (P < 0.01), but the amount of silt, sand, K, P, calcium (Ca), lime, and SOM increased (P < 0.01). UG improves soil quality, MG intensity causes optimal conservation and utilization of soil resources, and HG intensity causes severe changes in rangeland soil properties. In areas with MG intensity, due to the increase of the percentage of vegetation (an increase of SOM and prevents the direct impact of raindrops on the soil aggregates) and as a result improvement of soil structure and texture, an increase of water infiltration, and decrease of runoff, and the rate of soil erodibility and water erosion, the rangeland soil decreases and results in sustainable production. This results in optimal conservation and utilization of soil resources. So to sustainably exploit and balance the conservation of biodiversity, livestock production, and soil carbon and nitrogen management, MG is recommended.

A critical review of biogas production and usage with legislations framework across the globe

This review showcases a comprehensive analysis of studies that highlight the different conversion procedures attempted across the globe. The resources of biogas production along with treatment methods are presented. The effect of different governing parameters like feedstock types, pretreatment approaches, process development, and yield to enhance the biogas productivity is highlighted. Biogas applications, for example, in heating, electricity production, and transportation with their global share based on national and international statistics are emphasized. Reviewing the world research progress in the past 10 years shows an increase of ~ 90% in biogas industry (120 GW in 2019 compared to 65 GW in 2010). Europe (e.g., in 2017) contributed to over 70% of the world biogas generation representing 64 TWh. Finally, different regulations that manage the biogas market are presented. Management of biogas market includes the processes of exploration, production, treatment, and environmental impact assessment, till the marketing and safe disposal of wastes associated with biogas handling. A brief overview of some safety rules and proposed policy based on the world regulations is provided. The effect of these regulations and policies on marketing and promoting biogas is highlighted for different countries. The results from such studies show that Europe has the highest promotion rate, while nowadays in China and India the consumption rate is maximum as a result of applying up-to-date policies and procedures.

Community distribution of oxygen: a unique COVID-19 intervention

The rapid spread of COVID-19 around the world has exposed some long-standing deficiencies in health systems, particularly in environments with low financial and medical resources. Most patients ill with COVID-19 require oxygen and supportive therapy for survival as there remains no conclusively established curative therapy. Following a number of critical research work and drawing from a millennia-long evolution of medical practice, respiratory support has been identified as a paramount intervention to ensure lives are saved when supportive care is required, and oxygen is an essential commodity to achieve this. This letter focuses on the numerous means for oxygen delivery to health facilities and in turn the end users and expands on the importance of innovation to improve oxygen supply. We describe a community distribution system with a telemedicine structure that can be leveraged for oxygen delivery.

Rethinking 'Bacha Bazi', a culture of child sexual abuse in Afghanistan

The global pandemic appears to be a never ending challenge. With the authorities' reach shrinking, we can assume that Bacha Bazi is celebrated more than before. Perpetrators not only harass individuals but also put public health in peril by organizing gathering and parties. With both individual and public health and rights at stake, this pandemic could also be a chance to contain Bacha Bazi practices. It may be early to say this and we definitely need to collect more information before we reach any conclusion, but most importantly, we, from healthcare workers and youth workers to policymakers, need to take action. Awareness is the spark of our mobilization. As citizens we can be more critical towards traditions involving any kind of abuse. As healthcare workers, we can be alert when treating boys, adolescents and young adults. We can probably spot a hidden case of abuse and refer the victim accordingly. As citizens we can support policymakers who are committed to take action against harassment of this, and any other, kind and this can also be a crucial chance to address the shadows haunting our societies once and for all.

Food Security and COVID-19 in Africa: Implications and Recommendations

Before the COVID-19 pandemic ravaged Africa, a large percentage of Africans were already affected by poverty and food insecurity. The pandemic wreaked havoc on their already unfavorable situation. The direct and indirect impacts of COVID-19 included but not limited to illness and deaths of food systems' workers, interruption of food supply chains, unemployment, depreciation of currency value, and disruption of social protection programs. COVID-19 will lead to further economic fallout. Thus, the situation needs careful observation and timely intervention to safeguard the vulnerable African communities. Although Africa has sought ways to lessen the dire impact of the pandemic on food security, short-term solutions should include and enhance social and economic relief initiatives such as monetary intervention and social safety net. Considering a balance between health benefits of COVID-19 restrictions and their economic implications, the African countries, at the regional level, must preserve open and efficient social protection programs and cross-border supply and distribution networks for agricultural inputs. Africa's medium- and long-term strategies for improving food security should include improving and diversifying its agricultural productivity and production of key food commodities. This will reduce Africa's dependence on importation of these key commodities, and will help the continent address underlying economic vulnerabilities and better manage food, pandemic, and/or health-related crises affecting food security in the long term.

The effect of lutein and Urtica dioica extract on in vitro production of embryo and oxidative status in polycystic ovary syndrome in a model of mice

BACKGROUND

Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrinopathies in women during the reproductive age. Herbal medicines are used increasingly alone or in supplement with chemical medicines for the treatment of different diseases and dysfunctions. This study was aimed to evaluate the effects of lutein and nettle (Urtica dioica) extract on the biochemical parameters and the reproductive function in the PCOS model of mice.

METHODS

Following the induction of PCOS by dehydroepiandrosterone (DHEA), the mice (n = 98) were randomly assigned into seven groups, each consisting of fourteen mice; the groups were included control group (received solvent), PCOS group (received 6 mg/100 g B.W/day IP, DHEA for 21 days), PCOS+ Nettle extract (200 and 400 mg/kg), PCOS+ Lutein (125 and 250 mg/kg), and PCOS+ NL (200 mg/kg nettle extract and 125 mg/kg lutein). The nettle extract and lutein were administrated using gavage for 30 consecutive days after PCOS induction. Malondialdehyde (MDA), total antioxidant capacity (TAC), and estrogen were measured in serum, ovary, and uterus samples by the ELISA method. The total number of oocytes, oocyte quality, fertilization rate, 2-cell blastocyst, and arrested embryos (type I, type II, and type III) were also investigated.

RESULTS

A combination treatment of the nettle and lutein produced the lowest concentration of MDA in comparison to other groups which affected by the PCOS. The lowest level of TAC was observed in the PCOS group without treatment. The number of oocytes, oocyte quality, fertilization rate, and 2-cell blastocyst were significantly higher in the control group, but the lowest values were observed in the PCOS group without any treatment.

CONCLUSIONS

The most favorable findings include improving antioxidant capacity, oocyte and embryo quality were observed in the PCOS+ 125 L group.

The calculated responses against COVID-19 in Namibia

COVID-19 has spread to many countries and infected a vast number of people around the world. Namibia is not spared from this disease. On the early days of the pandemic in Namibia, the government instituted a four-stage strategy--from a full lockdown in Stage One with gradual relaxation of restrictions in Stage Two and ending with Stage Four. This was proven to be effective since the number of daily new cases were minimal by the time the restrictions were lifted in Stage Four, which allowed many non-essential businesses to resume, and borders to reopen. However, following this, the cases jumped in an alarming pace. The situation was also exacerbated partly by obliviousness of the people to restrictions due to their economic issues. At present, the government struggles to bring the situation back under control. Thus, the government reintroduced new restrictions to mitigate the situation. The country is facing paucity of facilities like personal protective equipment (PPE), health workers, intensive care unit (ICU) equipment and testing kits. To avoid further explosion of cases, Namibia needs to determine relaxation of restrictions based on the indicators of the situation of COVID-19. Assistance to the population and addressing insufficiency of facilities by the government through innovative solutions are of utmost importance in tussling the virus.

Long-term grazing exclosure: implications on water erosion and soil physicochemical properties (case study: Bozdaghin rangelands, North Khorasan, Iran)

Grazing exclosure (GE) is used to improve rangelands in the dry area of the world, so it is important to investigate its effects on soil physicochemical and erodibility properties. This study was conducted to evaluate the effect of long-term GE on the physicochemical and erodibility properties of soil and vegetation as compared with open grazing (OG) areas in Bozdaghi region of North Khorasan province, Iran. Soil and vegetation data were sampled from two sites in the grazing exclosure and the open grazing in early autumn in a randomized complete block design with three replications. Therefore, in each area (GE and OG), three transects of 500-m length and 200-m intervals) were set up. Along each transect, five soil samples were taken at the depths of 0-15 and 15-30 cm in a random-systematic method (15 soil samples in each area) and transferred to the laboratory. In the laboratory, some soil physicochemical properties such as saturation percentage, soil texture (clay, silt, and sand), bulk density, porosity, percentage of soil organic matter (SOM), total nitrogen (TN), exchangeable sodium, potassium, pH, and electrical conductivity (EC) were measured and Soil Erodibility Index (SEI) was calculated by using the modified clay ratio relation. After installing the transects (with a length of 50 m) in three blocks in each area, the parameters of species composition and canopy cover were investigated by the linear-contact method. Data analysis was performed by using an independent t test on Statistical Package for Social Sciences (SPSS) v. 23 software. The results indicate that the application of GE in the Bozdaghi area has a significant positive effect on soil physicochemical properties (P < 0.05). Also, the application of GE has increased the amount of SOM and TN in the surface layer of the soil by about twice as much as the OG pastures. Due to these changes, during 20 years in the GE area, the effects of GE can be positively assessed. According to the obtained results, especially the positive changes in vegetation and the soil physicochemical and erodibility properties, it is recommended to execute the GE plan in the study area.

Understanding the Slow COVID-19 Trajectory of Cambodia

COVID-19 has resulted in large number of mortalities across the globe. However, Cambodia has recorded low number of COVID-19 cases with no death. A number of factors buttress the accuracy of this phenomenon such as significant support from international health partners, culture of wearing a face mask when sick, timely response of Cambodia’s neighbouring countries, and the compliance of the general public to the restrictions. Cambodia started to take stringent measures and augmented efforts to initiate policies and plans to curb the spread of the virus, including but not limited to: closure of inbound and outbound borders, shutting down of schools, and banning religious activities, gatherings and meetings, with more than 50 people. Another source of success of Cambodia is extensive mass testing, complemented with contact tracing. A strategy called “box in” the virus was introduced. Healthcare workers were trained to help in contact tracing and detection at the community level. Measures enacted so far has helped Cambodia control the pandemic. Other countries could adopt and adapt to the policies and best practices of Cambodia. However, possibilities of new waves of the pandemic may affect the country, thus, the Cambodian government needs to be cautious when lifting restrictions to avoid explosion of new cases.

South Sudan: a young country's fight against COVID-19

COVID-19 is a highly infectious disease that has started to creep into African countries including South Sudan. Following confirmation of the first few cases, the government enacted preventive measures to curb community transmission. However, daunting challenges deter these precautionary measures. Just after two years the country took its independence from Sudan, civil conflicts sparked and continue to overburden and undermine the fragile healthcare system. The conflicts have caused disruption of health services, destruction of health facilities, death and migration of health workers, displacements of a huge number of people. This scenario continues while the country is grappling with the pandemic. Other concerning issues include: insufficient COVID-19 testing capacity, limited medical and personal protective equipment and an inadequate number of health workers which leave the country ill-equipped in the battle against the pandemic. Non-compliance of COVID-19 prevention protocols by the general public due to high rate of poverty and social stigma contribute to the spread of the virus. The current situation in South Sudan make evident that there is a need for an immediate ceasefire by the warring sides so the available health services including COVID-19 efforts, are not disrupted to ensure the safety of all. The government needs to further build the capacity of its health sector with the cooperation of its international health allies to be able to provide its citizens with the health services they need.

Polio Amidst COVID-19 in Pakistan: What are the Efforts Being Made and Challenges at Hand?

Poliomyelitis, a crippling viral disease, has been affecting many children in Pakistan despite the numerous efforts that have been taken to curb its spread. The COVID-19 pandemic has halted mass polio vaccination campaigns globally, including Pakistan, resulting in a resurgence of new cases. Pakistan managed to flatten the COVID-19 curve from July to October that made three immunization drives possible, but the COVID-19 cases are on the rise again which can again complicate the polio situation in the country if left unmonitored. The efforts of Pakistan have been effective with no significant rise in polio cases in 2020 as compared with 2019. We discuss the numerous challenges faced by the polio eradication program in Pakistan. To help eliminate polio, Pakistan needs to enhance its efforts in the struggle against polio with the same zeal and stringency used to flatten the curve of COVID-19 in these challenging times.

Drug shortage crisis in Sudan in times of COVID-19

Sudan is witnessing severe drugs, medicines, and medical supplies shortages, which present a major impediment to the provision of emergency healthcare services. Drug insecurity in Sudan is as a result of several accumulated factors, primarily due to worsening economic condition, inappropriate pricing policy, privatization of the pharmaceutical sector, poor manufacturing and weak weak weregulatory system. These could threaten patient health through replacement of highly efficacious medicines with less effective alternatives and by impacting the scheduling of urgent medical operations and procedures. Drug and medicine shortages are of catastrophic impact especially amid the current epidemic of COVID-19 where these are salient needs. Efforts should be quickly directed to ensure immediate access to pharmaceutical products and other essential health commodities. Effective policies on drug importation, production, pricing, and distribution should be established to avoid the consequences of an impending crisis.
