Floods, landslides and COVID-19 in the Uttarakhand State, India: Impact of Ongoing Crises on Public Health

The Uttarakhand State, known for its Himalayan Mountains, is a territory in Northern India that is extremely vulnerable to earthquakes, landslides, and floods. Currently, due to the COVID-19 outbreak, India is facing the dual challenge of containing a pandemic and responding to natural disasters. This situation can have a negative impact on the health and the economic development of the region, leading to a long-lasting humanitarian crisis that can disrupt even more, the already overburdened health service. In addition, it can pose serious threats to the wellbeing of the population as it complicates physical distancing and other COVID-19 prevention measures. It is of utmost importance to analyse the impact of floods, landslides, and COVID-19 pandemic on the health system of the Uttarakhand State, and how these crises interact with each other.

Impact of family-based selection on growth performance and immune response of Japanese quail

The present study was aimed to evaluate the growth performance and immune response of three genetic lines of Japanese quails. These lines i.e., selected for 4-week body-weight group (WBS), selected for egg number (EBS), and random-bred control (RBC), were selected for three consecutive generations from a base population of 1125 quails. In total, 2700 four-week-old quails from three selected groups were slaughtered in total of four generations (G0 to G3). Effects of selection and generations as well as their interactions were assessed for growth performance and immune response by applying a two-way analysis of variance. Significant means were compared with Duncan's Multiple Range Test. The statistical analysis showed a significant effect of selection and generations on most of the growth and immune response parameters. WBS in G3 presented significantly higher values of body weight, weight gain, and FCR than RBC and EBS. FCR was better in WBS during G3 than those of EBS and RBC. However, Livability% was highest in RBC while the lowest was noted in G3 of WBS line. Thymus% and spleen% were higher in EBS as compared to RBC and WBS. RBC presented a better B/S ratio and ND titer than those of EBS and WBS. The decreasing trend of ND titer in both lines of WBS and EBS as compared to RBC suggested a decrease in New Castle disease resistance in progressive generations of selection. It was concluded that selection for body weight and egg number has a positive impact on respective traits but negatively affects the immunity in later generations.

Assessment of Knowledge, Attitude, and Practice of Health-Care Workers Towards Hepatitis B Virus Prevention in Kabul, Afghanistan

Background

Hepatitis B virus (HBV) infection is a serious public health issue around the world. Health care workers (HCWs) are at high risk of HBV infection because they have direct contact with HBV infected blood and body fluids in their work.

Objective

The purpose of this study was to evaluate the knowledge, attitude, and practice (KAP) of HCWs towards hepatitis B infection in Kabul, Afghanistan.

Methods

This cross-sectional study was conducted on 502 HCWs, between November 2018 and January 2019 by a simple random sampling method. The data was collected through a self-administered structured questionnaire. Using this questionnaire, demographic characteristics and KAP of HCWs was assessed. In addition, descriptive and inferential analyses was conducted on the collected data using SPSS 16 (SPSS Inc., Chicago, IL, USA).

Results

The overall KAP scores of HCWs were found to be 86.58%, 34.73%, and 61.22%, respectively. Most of the participants correctly recognized the HBV infection. Among the participants, only 77.45% had undergone screening for HBV, and 56.37% had received HBV vaccine (p < 0.0001). Moreover, only 6.77% had completed the three doses of vaccination for HBV. Among the HCWs, the group with higher education level had better knowledge than the group with lower education level. However, the attitude of most of the participants towards HBV prevention was found to be inadequate (53.98%).

Conclusion

This study shows that HCWs in Kabul, Afghanistan are at high risk of HBV infection due to low vaccination coverage and inadequate infection control. Therefore, we strongly encourage providing an accessible and compulsory vaccination program for all HCWs to improve their attitude and awareness towards HBV infection and to achieve effective infection control.

Electrochemical distinction of neuronal and neuroblastoma cells via the phosphorylation of the cellular extracellular membrane

In this contribution we establish a proof of concept method for monitoring, quantifying and differentiating the extracellular phosphorylation of Human SHSY5Y undifferentiated neuronal cells and neuroblastoma cells by three prominent ectokinases PKA, PKC and Src. Herein it is demonstrated that a combination of different experimental techniques, including fluroesence microscopy, quartz crystal microscopy (QCM) and electrochemistry, can be used to detect extracellular phosphorylation levels of neuronal and neuroblastoma cells. Phosphorylation profiles of the three ectokinases, PKA, PKC and Src, were investigated using fluorescence microscopy and the number of phosphorylation sites per kinase was estimated using QCM. Finally, the phosphorylation of the extracellular membrane was determined using electrochemistry. Our results clearly demonstrate that the extracellular phosphorylation of neuronal cells differs significantly in terms of its phosphorylation profile from diseased neuroblastoma cells and the strength of surface electrochemical techniques in the differentiation process. We reveal that using electrochemistry, the percent compositions of neuronal and neuroblastoma cells can also be identified.

Λ_{c}^{+} Production and Baryon-to-Meson Ratios in pp and p-Pb Collisions at sqrt[s_{NN}]=5.02 TeV at the LHC

The prompt production of the charm baryon Λ_{c}^{+} and the Λ_{c}^{+}/D^{0} production ratios were measured at midrapidity with the ALICE detector in pp and p-Pb collisions at sqrt[s_{NN}]=5.02  TeV. These new measurements show a clear decrease of the Λ_{c}^{+}/D^{0} ratio with increasing transverse momentum (p_{T}) in both collision systems in the range 2<p_{T}<12  GeV/c, exhibiting similarities with the light-flavor baryon-to-meson ratios p/π and Λ/K_{S}^{0}. At low p_{T}, predictions that include additional color-reconnection mechanisms beyond the leading-color approximation, assume the existence of additional higher-mass charm-baryon states, or include hadronization via coalescence can describe the data, while predictions driven by charm-quark fragmentation processes measured in e^{+}e^{-} and e^{-}p collisions significantly underestimate the data. The results presented in this Letter provide significant evidence that the established assumption of universality (colliding-system independence) of parton-to-hadron fragmentation is not sufficient to describe charm-baryon production in hadronic collisions at LHC energies.

Challenges of Conducting Point-Of-Care Testing Operations During The COVID-19 Pandemic In The Municipal Public Health System Based Ambulatory Care And School Health Clinics In New York City

Introduction/Objective

Our New York City Municipal Public Health System based multisite ambulatory clinics and school-based clinics, offer various waived POCT (point of care tests) and provider performed microscopy (PPM). To ensure standardization and quality of POC testing across our health system, our laboratory service conducts system wide centralized implementation, monitoring and oversight of the POCT operations in regard to regulatory compliance, test performance, quality control and training. With the emergence of the COVID-19 infection in the New York City, like all other clinical laboratories, our ambulatory care clinics encountered numerous hurdles and challenges. Here we elaborated the issues that we encountered and how we managed to overcome during the COVID-19 Pandemic.

Methods/Case Report

We categorized the challenges that affected our managers as well as field level laboratory operations and have devised a plane to deal with COVID-19 related predicaments.

Results (if a Case Study enter NA)

Among the staffing issues, staff relocation to the acute care hospital laboratories during the peak of the pandemic caused massive delay or cessation of POCT operations in our ambulatory care clinics. Manual result entry, for COVID-19 testing, at the patient portals due to lack of interface with the reference testing labs, staff shortages and frequent absences due to illness and fatigue were primary issues noted at technical level. Furthermore, there were notable delays in the processing of paper works and new staff recruitments. The lack of and significant delays in the critical laboratory supplies was another major management issue.

Conclusion

Given the vastness and complexity of our multisite ambulatory care network, the COVID -19 pandemic impacted our ambulatory care clinic POCT operation in a very challenging way. However, our timeliness, coordinated interventions, close communications and initiatives handled the obstacles that arose very effectively to the ensure quality of POC testing, patient safety and quality care across our health system.

Ensuring Standardization, Quality Management And Improvement Of Point-Of-Care Testing In The Municipal Public Health System Based Ambulatory Care And School Health Clinics In New York City

Introduction/Objective

Operated under different acute care hospital clinical laboratory limited-service laboratory (LSL) licenses, our New York City five borough spanning multisite ambulatory clinics and school-based clinics have been offering various waived point-of-care tests (POCTs) and provider-performed microscopy (PPM) to the local communities. A wide range of variability existed among the clinics concerning regulatory compliance, test performance, quality control and training. To ensure standardization and quality of POCT across the health system, our laboratory service adopted and implemented a plan for systemwide LSL transfer from the acute care hospitals to ambulatory care laboratory service for centralized implementation, monitoring, and oversight of the POCT operations.

Methods/Case Report

Having over 60 clinics, while transferring the LSLs, we chose multi-site license with ten or more sites on each license and by phase transfer from NYSDOH. Since the commencement of the transfer, system wide our qualified laboratory personnel have been updating and providing standard operating procedures (SOP), performing quality assurance and validation of new tests/devices, providing competency assessments and helping clinical staffs maintain compliance with state and other regulatory agencies.

Results (if a Case Study enter NA)

After the final phase of the transfer and POCT standardization implementation in 63 clinics, currently the clinical staffs performing POCT, get expeditious training and troubleshooting in more timely manner and the providers get the results of the ordered POCTs much faster and more efficiently and overall the quality metrics get improved markedly, indicated by internal audit team.

Conclusion

Even though Implementation of the planned POCT standardization was initially challenging due to the vastness and complexity of our multisite ambulatory care network and later confounded by the COVID -19 pandemic effect but eventually, it helped improve patient care delivery significantly and very effectively. Expectedly, our planned transfer implementation provided standardization and ensured improved quality of POC testing across our health system.

HIV/AIDS among children in Ratodero, Pakistan amidst the COVID-19 pandemic: Challenges, efforts, and recommendations

It is a public health challenge amidst the COVID-19 pandemic that is not being given due importance. The present article looks at the challenges and efforts being made to deal with HIV among children in Ratodero, Pakistan, and addresses measures that can be taken to control the disease in the child population epidemiologically.

Experimental Evidence for an Attractive p-ϕ Interaction

This Letter presents the first experimental evidence of the attractive strong interaction between a proton and a ϕ meson. The result is obtained from two-particle correlations of combined p-ϕ⊕ p[over ¯]-ϕ pairs measured in high-multiplicity pp collisions at sqrt[s]=13  TeV by the ALICE Collaboration. The spin-averaged scattering length and effective range of the p-ϕ interaction are extracted from the fully corrected correlation function employing the Lednický-Lyuboshits approach. In particular, the imaginary part of the scattering length vanishes within uncertainties, indicating that inelastic processes do not play a prominent role for the p-ϕ interaction. These data demonstrate that the interaction is dominated by elastic p-ϕ scattering. Furthermore, an analysis employing phenomenological Gaussian- and Yukawa-type potentials is conducted. Under the assumption of the latter, the N-ϕ coupling constant is found to be g_{N-ϕ}=0.14±0.03(stat)±0.02(syst). This work provides valuable experimental input to accomplish a self-consistent description of the N-ϕ interaction, which is particularly relevant for the more fundamental studies on partial restoration of chiral symmetry in nuclear medium.

Revision of some mensural measurements, food preference, and haematological parameters in breeding pairs of blue rock pigeon, Columba livia sampled from punjab Pakistan

The present study describes the haematological profile, feeding preference, and comparison of morphometric characters of blue rock pigeon (Columba livia) breeding pairs. For this purpose, 25 pairs (25 samples per sex) were sampled through Mist nets from district Okara and Bahawalnagar, Punjab, Pakistan. Birds were then anaesthetized with a combination of ketamine HCL (10 mg/kg) and diazepam (0.2 mg/kg) and subjected to morphometric measurements. 5µL blood also was taken from the jugular vein of each anaesthetized bird for haematological analysis. Few pairs were also dissected to remove gastrointestinal tracts (GITs) for food preferences. Results revealed that there are no significant differences in the haematological parameters and feeding preference of breeding pairs of Columba livia. The gut analysis further revealed, the major portion of gut contents consisted of pea and corn in most of the pairs. Regarding the mensural measurements, significant differences were recorded in the body weight, length of the longest primary feather, and chest circumference, whereas the rest of the studied parameters remain nonsignificant between sexes. So, it is concluded that apart from 3 morphometric parameters (body weight, length of longest primary feather and chest circumference), both sexes are alike in term of morphometry, haematology and food preference.

Gene and protein expression profiles of selected molecular targets mediating electrophysiological function in pgc-1-alpha deficient murine ventricles

Background

The risk of cardiac arrhythmias increases significantly in patients with metabolic disorders such as obesity and diabetes mellitus. The mechanisms linking metabolic conditions and electrophysiological changes underlying cardiac arrhythmias remain poorly understood. Central to the energetic abnormalities characterising these conditions is mitochondrial dysfunction. Peroxisome proliferator activated receptor-γ (PPARγ) coactivator-1 (Pgc-1) regulate mitochondrial biogenesis and function. Their expression is impaired in metabolic disorders. Murine Pgc-1α−/− hearts replicate disrupted mitochondrial function and model the associated pro-arrhythmic electrophysiological abnormalities.

Purpose

To explore the molecular mechanisms underlying the pro-arrhythmic electrophysiological changes in the Pgc-1α−/− murine model of mitochondrial dysfunction.

Methods

Ventricular tissue samples were obtained from aged (&gt;12 months) wild-type (WT) and homozygous Pgc-1α−/− mice. Quantitative PCR was used to examine transcription of 60 genes underlying cardiac tissue excitability, western blotting was used to examine expression of proteins relating to cardiac conduction velocity, and histological analysis was used to examine cardiac tissue fibrotic change.

Results

qPCR analysis implicated downregulation of genes related to Na+-K+ ATPase activity (Atp1b1), surface Ca2+ entry (Cacna1c), action potential repolarisation (Kcnn1), autonomic function (Adra1d, Adcy4, Pde4d, Prkar2a), and morphological properties (Myh6, Tbx3) in murine Pgc-1α−/− ventricles. Western blotting revealed reduced NaV1.5 but normal Cx43 expression. Histological analysis revealed increased tissue fibrosis in the Pgc-1α−/− ventricles.

Conclusions

These results identified molecular mechanisms underlying previously reported electrophysiological abnormalities such as impaired ventricular activation and reduced conduction velocity in arrhythmic substrate associated with Pgc-1 deficiencies. Results also correlated with earlier findings including functional effects of elevated Ca2+ concentrations. The present findings clarify possible mechanisms by which mitochondrial dysfunction affects electrophysiological function and identify potential pharmacological targets for anti-arrhythmic therapy.

543 Improving the Management of Acute Ureteric Colic in A Multi-Centre District General Hospital: A Closed-Loop Audit

Introduction

The British Association of Urological Surgeons (BAUS) released guidance in 2018 regarding the optimum management of acute ureteric colic: a condition which can present as a surgical emergency. Our aim was to review the current practice at our hospital in diagnosing and managing acute ureteric colic and ultimately, implement sustainable change to address any areas of limitations.

Method

The following data was retrospectively collected for of all patients admitted with acute ureteric colic: investigations performed, medications administered, details of surgical intervention and follow-up. 1st Cycle: March 2017 to February 2018. Intervention: Teaching sessions delivered to staff (including doctors and nurses) in the A&E and urology department. 2nd Cycle: January 2019 to December 2019.

Results

268 patients presented to A&E with ureteric colic – 18% increase from previous year. On admission: 60.4% of patients had serum calcium checked, 97.7% had a CT KUB performed within 24 hours and 67.2% were given NSAIDs; this is a 20.4%, 0.4% and 5.2% increase from the previous year, respectively. Only 31.3% of patients had an acute surgical intervention. The average wait time for clinic follow-up was reduced to 41 days following departmental education, but only 26.4% of patients were seen within the BAUS advised 4-week timeframe.

Conclusions

Re-audit showed distinct improvement in the management of acute ureteric colic. Thus, departmental education strategies have had a positive impact. It is recommended that the reservation of one daily elective theatre slot for an emergency operation and a computerised clinic booking system will further optimise our management in line with BAUS guidance.

Morphometric measurements and carcass characteristics of Black Australorp, Naked Neck, and Rhode Island Red crossbreds under alternative production systems

The present trial explained the effect of alternative production systems on growth, morphometric and carcass traits of four different chicken genotypes. The second generation of two genotypes RNN (Rhode Island Red × Naked Neck) and BNN (Black Australorp × Naked Neck) obtained by two self-crosses (RNN × RNN = RR and BNN × BNN = BB) and two reciprocal crosses (RNN × BNN = RB and BNN × RNN = BR) were evaluated in three alternative production systems (conventional cages, enriched cages, and aviary). At the 6th week of age after sexing, a total of 600 birds, comprising 150 from each crossbred with a total of 300 pullets and 300 cockerels were divided into conventional cages, enriched cages, and aviary systems having 200 birds in each.Birds were organized into 3×4 factorial arrangements under Completely Randomized Design (3 production systems × 4 genotypes × 2 sexes × 25 birds = 600 birds). Regarding genotypes, RB and BR males showed higher (p < 0.01) carcass yield, drumstick weight, breast weight, and thigh weight than BB and RR genotypes. Females of BR genotype showed higher (p < 0.01) breast weight, thigh weight and drumstick weight. As far as production systems are concerned, higher (p < 0.01) liver weight, heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight were observed in the males reared in enriched cages compared with conventional cages and aviary system. Females reared in enriched cages showed higher (p < 0.01) heart weight, breast weight, intestinal weight, drumstick weight, and thigh weight when compared with those reared in conventional cages and aviary. It is concluded that chickens (both sexes) of BR and RB genotypes had better morphological measurements and carcass traits than those of RR and BB genotype chickens. Among alternative production systems, chickens reared in enriched cages had better traits than those of reared in conventional cages and aviary during the growing phase.

Antiviral and antiretroviral drug shortages amidst COVID-19: How Africa is struggling

Antiviral drugs are of paramount importance in the accomplishment of the vision of zero new cases of COVID-19 globally, through sustainable retaliation against viral diseases. However, several challenges currently exist in Africa which include insufficient infrastructure, deteriorating health systems, and rising costs of healthcare delivery with concomitant rising inequity with regards to access to health services amid the COVID-19 pandemic. The pandemic itself has stimulated an increased use of phytotherapy in Africa as a result of essential drug shortages that have been attributed to a plethora of contributing factors such as travel restrictions, reduced per capita income as well as increased expenditure on transport. As a result, the paucity of antiviral along with antiretroviral drugs used to combat COVID-19 as well as several other endemic viral diseases in Africa has created a worrisome state. This article therefore discusses and aims to underscore the causes, effects, and implications of antiviral and antiretroviral shortages amid COVID-19 in Africa.

Body composition, growth performance and enzyme activities of Labeo rohita fed different commercial fish feeds

We have evaluated the effects of different fish feeds on the body composition, growth, and enzyme activities of Labeo rohita (Rohu). In total, 240 fishes between the average weights of 24.77±2.15g were studied. The treatments were applied in a completely randomized design, with 4 treatments of 60 fishes each. Treatments consisted of four different fish feeds [Oryza (T1), AMG (T2), Aqua (T3), and Supreme (T4)]. Body composition, growth performance, and enzyme activities were evaluated. There was a significant variation in performance of fishes fed with different type of feed; as fishes having Oryza feed showed the highest weight gain, specific growth rate (SGR), and best feed conversion ratio (FCR) as compared to other groups that were considered to be significant (P ≤ 0.05). High net weight gain was obtained in T4 when compared with T2 and T3. FCR value of T4 was less than T1 but higher than T2, T3 and T2, which showed the lowest values. The specific growth rate was recorded as average in T4, but T2 led a high SGR than T3. Similarly, crude protein level and digestive enzymes activity was recorded significantly highest in fed with Oryza (T1) as compared to AMG (T2), Aqua (T3), and Supreme (T4). Water quality parameters were recorded significant in all treatments except pH and DO of treatment (T1), significantly different from other treatments. It was concluded that Rohu (Labeo rohita) could show a promising growth rate and protease enzyme activity when fed with the Oryza feed of 25% protein.

Irreversibility effects in peristaltic transport of hybrid nanomaterial in the presence of heat absorption

The nano heat transport has gained much significance in recent era. The micro-level devices are enganged succssfully in diverse fields like electronics, biomedical, navel structures, manufacturing, transportation, and automotive industries in order to improve the heat transfer for cooling and heating. Owing to this fact, the current article illustrates the features of irreversibility and thermal jump in peristaltic transport of hybrid nanoliquid. Here, water is used as base liquid while nanoparticles include polystyrene and graphene oxide. The flow is carried out in a non-uniform channel where the walls of channel flexible nature. Additionally, magnetic field impacts on flow and Joule heating analysis are examined. The aspect featuring heat absorption is introduced. Nanoparticle's shapes effect is also incorporated in flow analysis. Under the consideration of small Rynold number and long wavelength, the relevent equations are reduced by implementing non-dimensional variables. Involved pertinent parameters influence the peristaltic flow characteristics are displayed graphically and discussed concisely. The result indicates that temperature curves are dominant for pure water as compared to P/water nanofluid and P-GO/water hybrid nanofluid. Moreover, the convergent channel shows least entropy effects and extreme effects are noted for divergent case whereas uniform channel stays behind the divergent one.

Isolation and characterization of bacteria residing in the oral, gut, and fecal samples of different pheasant species

There is a paucity of research conducted on microbial prevalence in pheasants. The microbiota of captive birds has zoonotic significance and must be characterize. Present study is therefore planned to assess the microbiota from oral, fecal and gut content of captive avian species. It will be helpful in characterization of harmful microbes. Different samples taken from oral, gut and feces of ring-necked pheasants (Phasianus colchicus), green pheasants (Phasianus versicolor), golden pheasant (Chrysolophus pictus) and silver pheasant (Lophura nycthemera). Samples were collected, diluted, and inoculated onto different agar plates (MacConkey, SS agar, MSA and nutrient agar) for cultivation of bacterial species. Colonies of E.coli, Staphylococcus spp. Brachyspira spp. and Campylobacter spp were observed based on colony morphology. Colony forming unit showed E. coli as frequently found bacteria in fecal, oral and gut contents of all the above pheasants. The overall significance difference was found among bacterial species of golden pheasants, green pheasant, ring-necked pheasant, and silver pheasants. It was concluded that E.coli is predominant isolated from heathy pheasants followed by Campylobacter, Staphylococcus and Brachyspira.

Self-Medication in Africa during COVID-19 Pandemic

Self-medication is known as “the usage of drugs, herbs or home remedies on one’s own initiative, or on the advice of another person, without consulting a doctor’. In Africa, self-medication has reached a critical stage, with people using and taking any drug regardless of how poisonous the material may be as long as unprofessional suggestions advocate it as a solution to their health problem. In this article, we looked at the consequences, effects, and recommendations for reducing the use of self-medication as a habit among Africans.

COVID-19 and multiple crises in Afghanistan: an urgent battle

The political and military advance of the Taliban, reduced healthcare capacity, and imminent humanitarian crisis risk exacerbating an already very serious threat posed by COVID-19 in Afghanistan. The continued rise of COVID-19 cases in Afghanistan appears inevitable, but poor diagnostic capacity prevents accurate case measurement, while vaccine provision is extremely limited. This letter highlights how the recent changes in Afghanistan risk exacerbating the COVID-19 and ongoing health emergency in the country.

Glycogen synthase kinase-3 (GSK-3) a magic enzyme: it's role in diabetes mellitus and glucose homeostasis, interactions with fluroquionlones. A mini-review

Diabetes mellitus (DM) is a non-communicable disease throughout the world in which there is persistently high blood glucose level from the normal range. The diabetes and insulin resistance are mainly responsible for the morbidities and mortalities of humans in the world. This disease is mainly regulated by various enzymes and hormones among which Glycogen synthase kinase-3 (GSK-3) is a principle enzyme and insulin is the key hormone regulating it. The GSK-3, that is the key enzyme is normally showing its actions by various mechanisms that include its phosphorylation, formation of protein complexes, and other cellular distribution and thus it control and directly affects cellular morphology, its growth, mobility and apoptosis of the cell. Disturbances in the action of GSK-3 enzyme may leads to various disease conditions that include insulin resistance leading to diabetes, neurological disease like Alzheimer's disease and cancer. Fluoroquinolones are the most common class of drugs that shows dysglycemic effects via interacting with GSK-3 enzyme. Therefore, it is the need of the day to properly understand functions and mechanisms of GSK-3, especially its role in glucose homeostasis via effects on glycogen synthase.

Malaria amidst COVID-19 in India: Challenges, Efforts, and Recommendations

Since the outbreak of COVID-19 in India, the country has faced a slew of new challenges, spawning a slew of other deadly viruses and diseases while also serving as a breeding ground for them. Not only did Malaria (a vector-borne disease) emerge as a coincidental outbreak during the pandemic, but many others did as well, causing severe diseases in humans due to flaws in health-care systems that were already overburdened with identifying, preventing, and treating the recently introduced coronavirus disease. Inadequate water cleanliness, as well as the delayed and misdiagnosis of Malaria with COVID-19 due to overlapping symptoms, are major impediments in the incidence of these unique outbreaks. Appropriate steps, such as providing clean water and diagnostic facilities to control Malaria cases, should be adopted to prevent such epidemics in the country.

Viral hepatitis amidst COVID-19 in Africa: Implications and recommendations

Hepatitis, a significant cause of mortality worldwide, results in around 1.34 million deaths each year globally. Africa is not exempt from the plague of Hepatitis. Around 100 million estimated individuals are infected with Hepatitis B or C. Egypt has the highest prevalence of cases of Hepatitis followed by Cameroon and Burundi. The continent is severely affected by the onset of the COVID‐19 pandemic, as the virus has added an additional burden on the already fragile continent. With the pandemic, it is presumable that Hepatitis like other viral diseases will pose a threat to collapsing healthcare system. Therefore, for Africa to become more resilient in the face of such menaces, including Hepatitis, further prevention policies are required to be implemented

Identification of terrestrial gastropods families found in district Swat, Pakistan

Very little is known about the malacofauna in district Swat of Khyber Pakhtunkhwa province, situated in the Northern part of Pakistan. The Swat valley possesses a variety of suitable environmental conditions, providing different types of habitats for both flora and fauna. Taken into consideration these points, the present study was conducted to explore the terrestrial snails diversity in agricultural and non-agricultural fields in the lower Swat valley. A total of 417 shells were collected from three sites: Kokarai, Kanju Township, and Deolai. Based on conchological features, three families: Bradybaenidae, Hygromiidae, and Zonitidae were identified using different terrestrial snail keys. In Kokarai and Deolai, shells of members of all the above-mentioned families were found from agricultural fields. In Kanju Township, shells of members of the family Bradybaenidae and Zonitidae were found. From these findings, it was concluded that district Swat possesses a significant malacofauna which was unexplored before and aided more to the existing literature on malacofauna. It also supports the idea that the agroecosystem is rich in species diversity. Further in-depth and extensive study is recommended to be carried out for a detailed taxonomy of the described terrestrial gastropod families.

Optimized biotransformation of acid-treated water melon peel hydrolyzate into ethanol

Today, global focus of research is to explore the solution of energy crisis and environmental pollution. Like other agricultural countries, bulk quantities of watermelon peels (WMP) are disposed-off in environment as waste in Pakistan and appropriate management of this waste is the need of hour to save environment from pollution. The work emphasizes the role of ethanologenic yeasts to utilize significant sugars present in WMP for low-cost bioethanol fermentation. Dilute hydrochloric acid hydrolysis of WMP was carried out on optimized conditions employing RSM (response surface methodology) following central composite design (CCD). This experimental design is based on optimization of ethanologenesis involving some key independent parameters such as WMP hydrolysate and synthetic media ratio (X1), incubation temperature (X2) and incubation temperature (X3) for maximal ethanol yield exploiting standard (Saccharomyces cerevisiae K7) as well as experimental (Metchnikowia cibodasensisY34) yeasts. The results revealed that maximal ethanol yields obtained from S. cerevisiae K7 was 0.36±0.02 g/g of reducing sugars whereas M. cibodasensisY34, yielded 0.40±0.01 g ethanol/g of reducing sugars. The yeast isolate M. cibodasensisY34 appeared as promising ethanologen and embodies prospective potential for fermentative valorization of WMP-to-bioethanol.

Cross-genera amplification and identification of Colpodella sp. with Cryptosporidium primers in fecal samples of zoo felids from northeast China

The protozoans include many intracellular human pathogens. Accurate detection of these pathogens is necessary to treat the diseases. In clinical epidemiology, molecular identification of protozoan is considered a more reliable and rapid method for identification than microscopy. Among these protozoans, Cryptosporidium considered being one of the important water-borne zoonotic pathogens and a major cause of a diarrheal disease named cryptosporidiosis in humans, domestic animals, and wild animals. This study was aimed to identify Cryptosporidium in zoo felids (N= 56) belonging to different zoo of China, but accidentlly Colpodella was encountered in the zoo felids sample and phylogenetic data confirmed this unexpected amplification from fecal samples using two-step nested-PCR. Phylogenetic analysis revealed the fact about the specific primers used previously by many researchers and cross-genera amplification. We came to know that genetically sequenced amplicon gives more accurate identification of species. This study suggests more investigation on Colpodella which has been neglected previously but gains the attention of researchers after identified from humans and animals and has been known to correlate with neurological symptoms in patients.

Acceptance Rates and Beliefs toward COVID-19 Vaccination among the General Population of Pakistan: A Cross-Sectional Survey

Developing countries like Pakistan have previously suffered from barriers to acceptance of vaccination by the public because of financial and belief barriers. This study aims to explore these beliefs and highlight concerns regarding vaccine hesitancy in the general population of Pakistan since they are a hindrance to an effective coronavirus disease-19 (COVID-19) immunization in the country. A cross-sectional study was performed involving 1,778 participants from all four provinces of Pakistan. Results from the study showed more than half of the participants to be unsure of the safety (50%) and efficacy (51%) of the vaccine, whereas 42% were concerned about the side effects of the vaccine. About 72% of the respondents planned to get vaccinated, whereas 28% refused to do so. Internationally made imported vaccines were more trusted by the participants. Forty-four percent of the participants agreed to receive the vaccine upon recommendation from a physician. Lastly, participants who believed in the efficacy of the polio vaccination also considered the COVID-19 vaccine to be safe and effective.

Efficiency of exogenous zinc sulfate application reduced fruit drop and improved antioxidant activity of 'Kinnow' mandarin fruit

‘

Kinnow' mandarin (Citrus nobilis L.× Citrus deliciosa T.) is an important marketable fruit of the world. It is mainstay of citrus industry in Pakistan, having great export potential. But out of total production of the country only 10% of the produce meets the international quality standard for export. Pre-harvest fruit drop and poor fruit quality could be associated with various issues including the plant nutrition. Most of the farmers do not pay attention to the supply of micro nutrients which are already deficient in the soil. Furthermore, their mobility within plants is also a question. Zinc (Zn) is amongst those micronutrients which affect the quality and postharvest life of the fruit and its deficiency in Pakistani soils is already reported by many researchers. Therefore, this study was carried out to evaluate the influence of pre-harvest applications of zinc sulfate (ZnSO4; 0, 0.4%, 0.6% or 0.8%) on pre-harvest fruit drop, yield and fruit quality of 'Kinnow' mandarin at harvest. The treatments were applied during the month of October i.e. 4 months prior to harvest. The applied Zn sprays had significant effect on yield and quality of the "Kinnow" fruit. Amongst different foliar applications of ZnSO4applied four months before harvest, 0.6% ZnSO4 significantly reduced pre-harvest fruit drop (10.08%) as compared to untreated control trees (46.45%). Similarly, the maximum number of fruits harvested per tree (627), fruit weight (192.9 g), juice percentage (42.2%), total soluble solids (9.5 °Brix), ascorbic acid content (35.5 mg 100 g-1) and sugar contents (17.4) were also found significantly higher with 0.6% ZnSO4 treatment as compared to rest of treatments and control. Foliar application of 0.6% ZnSO4 also significantly improved total antioxidants (TAO) and total phenolic contents (TPC) in fruit. In conclusion, foliar spray of ZnSO4 (0.6%) four months prior to harvest reduced pre-harvest fruit drop, increase yield with improved quality of 'Kinnow' mandarin fruit.

Enterotoxigenic methicillin resistant Staphylococcus aureus contamination in salted fish from Gwadar Balochistan

Staphylococcus aureus is an important foodborne pathogen associated to food intoxication and other multiple infections in human being. Its presence in salted food is a serious issue due to its salt tolerance potential. A study was conducted to analyze the presence of enterotoxins producing drug resistance S. aureus in salted sea fish from Gwadar. Freshly persevered samples (n=50) of salted fish were subjected to analyze the presence of S. aureus using 16S rRNA and Nuc genes primers. The isolates were then evaluated for drug resistance and enterotoxins producing potential using specific primers for MecA (methicillin resistance gene), (SEA) staphylococcal enterotoxin A and (SEB) staphylococcal enterotoxin B genes. Total 13/50 (26%) of the samples were found positive for the presence of S. aureus, preliminary confirmed with biochemical profiling and finally with the help of target genes presence. The isolates were found showing 100% resistant to methicillin, which were molecularly confirmed by the presence of MecA gene present in genome. The isolates 5/13 (38%) were positive for SEA and 3/13 (23%) for SEB genes, whereas 2/13 (15%) were confirmed having both SEA and SEB genes in its genome. It was also confirmed that all the isolates were capable to form biofilm over the glass surfaces. It was concluded that the study confirmed the presence of enterotoxigenic methicillin resistance Staphylococcus aurous (MRSA) in salted fish product, that poses gross food safety concern. Preventive and control measures are necessary to handle this serious food safety concern.

The genes road: impact of migration on newborn screening and health amid the COVID-19 pandemic in the Eastern Mediterranean region

Nearly two-thirds of migrants residing in camps in Europe are women and children. Many of these children, being born on the way without essential newborns screening, are at some point admitted to pediatric wards in asylum countries. With hospitals overwhelmed with COVID-19 cases, taking appropriate care of newborns becomes a considerable burden. In this frame, prevention, in the form of adequate newborn screening, emerges as a better and more feasible strategy than healing.

Emergence of highly infectious SARS-CoV-2 variants in Bangladesh: the need for systematic genetic surveillance as a public health strategy

Bangladesh, a low-middle-income country in South Asia is facing one of its worst public health emergencies due to the COVID-19 pandemic. The increase in the number of cases from the disease, since the second half of March 2021, can potentially cause the health system overload, and has, as one of the main reasons, the non-compliance with measures of social distance and the emergence of the variants of concern in the country. This increase in the contagion curve can also provide a favorable environment for the occurrence of more mutations in the structure and genome of the virus. Therefore, there is an urge to carry out genomic surveillance programs in order to identify, monitor and characterize these variants, and understand whether the vaccines currently used are effective against them.

Rampant Increase in Cases of Mucormycosis in India and Pakistan: A Serious Cause for Concern during the Ongoing COVID-19 Pandemic

COVID-19 is a global health crisis that continues to pose new challenges all around the world. Amidst the growing pandemic, a spike in the number of mucormycosis cases in India and Pakistan has been reported in COVID-19 patients and in those who have recovered from COVID-19. This increase in cases may be related to the overuse of steroids and zinc, the use of industrial oxygen, unsterilized medical equipment, frequent intubation, a weakened immune system, and pre-existing comorbidities such as diabetes. As a result, it is critical to take steps to handle the current increase in mucormycosis cases. Therefore, this article aims to highlight the existence of mucormycosis amidst the COVID-19 pandemic in India and Pakistan, focusing on possible causes and implications, and suggests important plans of action to be taken during this pandemic.

Multiharmonic Correlations of Different Flow Amplitudes in Pb-Pb Collisions at sqrt[s_{NN}]=2.76 TeV

The event-by-event correlations between three flow amplitudes are measured for the first time in Pb-Pb collisions, using higher-order symmetric cumulants. We find that different three-harmonic correlations develop during the collective evolution of the medium when compared to correlations that exist in the initial state. These new results cannot be interpreted in terms of previous lower-order flow measurements since contributions from two-harmonic correlations are explicitly removed in the new observables. A comparison to Monte Carlo simulations provides new and independent constraints for the initial conditions and system properties of nuclear matter created in heavy-ion collisions.

Diversity, distribution and relative abundance of the mosquito fauna (Diptera: Culicidae) of Malakand and Dir Lower, Pakistan

The present study was conducted to evaluate the diversity, distribution (C) and relative abundance (RA) of the mosquito fauna (Diptera: Culicidae) of Malakand and Dir Lower, Pakistan. Collection of specimens (n = 1087) was made during September 2018 to July 2019 at six different habitats including freshwater bodies, rice fields, animal sheds, indoors, drains and sewage waters. Specimens were collected through light traps, pyrethrum spray, aspirators and nets and subsequently killed, preserved and then arranged in entomological boxes for identification. Three genera were identified namely Culex, Anopheles and Aedes. A total of fourteen species were identified namely: Cx. quinquefasciatus (Say, 1823), An. stephensi (Liston, 1901), Cx. tritaeniorhynchus (Giles, 1901), Ae. vittatus (Bigot, 1861), An. maculatus (Theobald, 1901), An. fluviatilis (James, 1902), Cx. vishnui (Theobald, 1901), Ae. aegypti (Linnaeus, 1762) An. subpictus (Grassi, 1899), An. dthali (Patton, 1905), An. culicifascies (Giles, 1901), An. pallidus (Theobald, 1901), Ae. albopictus (Skuse, 1894) and An. annularis (van der Wulp, 1884). Cx. quinquefasciatus was found constantly distributed in the study area with RA = 16.5% and C = 100%. An. annularis was found as a satellite species, sporadically distributed in the study area having RA = 0.9% and C = 17%. Diversity indices of mosquitoes in the studied habitats were found as, Shannon-Wiener Index (2.415), Simpson Index (9.919), Fisher's Index (2.269) and Margalef's Index (1.859). A statistically significant difference was recorded in mosquito diversity in the six habitats (Kruskal-Wallis, chi-squared, H = 17.5, df = 5, P = 0.003 at α = 0.05). The present study encompasses mosquito fauna of Malakand, Pakistan with respect to diversity, relative abundance and distribution in diverse habitats and all seasons of the year. This will assist scientists working in various fields related with epidemiology, medical and veterinary entomology, ecology and allied areas of biological sciences.

Feral dogs in Chitral gol national park, Pakistan: a potential threat to the future of threatened Kashmir Markhor (Capra falconeri cashmiriensis)

Feral dogs are well-organized hunters of ungulates in many parts of the world, causing great damage to wildlife populations and ultimately to the ecosystem. In Pakistan, the impacts of feral dogs on the wildlife have not been documented yet. In a period of fifteen years (2006-2020), feral dogs have killed hundreds of threatened markhor in Chitral gol national park (CGNP), Pakistan. Despite direct predation other impacts including disturbance and competition with other natural predators, could compromise conservation and management efforts. The population of feral dogs seems to have been increased with the increase of dumping sites by communities. Our findings suggest that there are pressing needs of controlling the feral dogs population and eradicating them from the core zone of CGNP and surrounding buffer communities. Conventional culling of dogs should be coupled with modern techniques like castration and sterilization. Communities should be educated regarding the clean environment, proper disposal of home wastes and, biodiversity conservation.

Ebola and COVID-19 in Democratic Republic of Congo: grappling with two plagues at once

In February 2021, a new Ebola virus disease outbreak was confirmed amid the COVID-19 pandemic in the Democratic Republic of Congo. Although the country has successfully contained the outbreak amid its fight against the COVID-19 pandemic, the epidemiological situation is still concerning, primarily due to the risk of an increase in the number of COVID-19 cases. The coexistence of both outbreaks increased the burden on the country’s health system mainly because Ebola response programs were redirected to the COVID-19 national response. Strategies adopted and lessons learned from previous Ebola outbreaks were crucial to developing the COVID-19 national response. To tackle the challenges of combating both the viruses, it is essential to adopt multidisciplinary measures such as prevention, education, and vaccination campaigns, promoting hygiene and social distancing practices, and improving diagnostic and management protocols. This paper discusses the efforts, challenges, and possible solutions to grapple with Ebola amid the COVID-19 crisis in DRC successfully.
