• AFTER THE REVOCATION OF THE SUBSIDIES, WHERE WILL THE INDONESIAN ECONOMY BE TAKEN? -
  Rising world fuel prices have become a serious problem for Indonesia, namely the increase in the burden of fuel subsidies for the community which has been enjoyed by hundreds of millions of Indonesians for decades. national. The discourse of increasing fuel is not as easy as turning the palm of the hand, but it will have a tremendous impact on the lower middle class, namely an increase in the rate of inflation. Rising inflation rates will automatically reduce people’s purchasing power due to a progressive increase in prices, of course this will be a problem for the lower middle class after the covid-19 pandemic for 3 years where the economic sluggishness is still felt as seen from the contraction in economic growth that has not yet reached the target set. has been determined and if it is followed by an increase in fuel prices, it is certain that a macroeconomic contraction will lead to a decrease in economic growth, high inflation rates, unemployment and the most frightening thing is an increase in the poverty rate. Is it true that the increase in fuel oil is the best solution for the Indonesian people?

• Cross-language Validation of COVID-19 Compliance Scale in 28 Languages -
  Objective: Although compliance scales have been used to assess compliance with health guidelines to reduce the spread of COVID-19, no scale known to us has shown content validity regarding global guidelines and reliability across a large international sample. Here, we have assessed the validity and reliability of the Compliance Scale developed by the COVIDiSTRESS II Global Consortium, a group of over 150 researchers from across the globe. Methods: We used exploratory factor analysis to determine the most reliable items on the English version of the survey. We conducted a measurement invariance test to determine whether the different language versions of the scale are measuring the same construct with the same measurement structure. Invariance testing indicated that measurement alignment was needed to ensure that the scales are comparable across languages and cultures. After alignment, we employed a novel R code to run MC simulation for alignment validation. Results: We found that alignment of the 6-item Compliance Scale worked well with this method. Confirmatory factor analysis confirmed reliability of the six-item scale. Convergent validity was also found; COVID-19 compliance correlated with vaccine willingness. Conclusions: The Compliance Scale can be employed quickly across multiple languages and countries, and our alignment validation method can be conducted freely in R and employed for future cross-language surveys.

• A rapid review of the effectiveness of remote consultations versus face-to-face consultations in secondary care surgical outpatient settings -

  The use of remote consultations and telemedicine approaches significantly increased over the pandemic. There is evidence that some patients still prefer this mode of care delivery and time saving may also enable additional consultations and help to reduce waiting lists. However, the effectiveness of remote consulting for certain specialities, such as surgery, is unclear. The aim of this review was to investigate the effectiveness of video or telephone consultations, particularly focusing on clinical, patient reported and safety outcomes, in adult secondary surgical outpatient care during the COVID-19 pandemic. 14 studies were identified. These were published in 2021-2022. Evidence is low or very-low quality due to observational study designs, small sample sizes and patient selection. Policy and practice implications: Evidence is of low quality but suggests that for many surgical outpatient consultations, remote consultations are as effective as in-person consultations. There is potential for time and cost savings for remote consultations compared to in-person consultations. High quality research is needed to evaluate the effectiveness of remote consultations to understand which patients and which surgical specialities would benefit most.

• Frequency and Risk Factors of Resident Burnout Before and During the COVID19 Pandemic -

  Objective: To explore the prevalence and contributing factors of resident burnout in a University Hospital before and during the COVID 19 pandemic. Methods: Thirty Faculty of Medicine departments were included in the survey, where 400 university hospital residents filled out the Maslach Burnout Inventory (MBI) in January 2018 and April 2020. Related scores of emotional exhaustion (EE), decreased accomplishment (DA) and depersonalization (DP) were calculated and compared between the different groups. Correlation between scores and possible contributing factors, including demographics, work-life circumstances, exposure to workplace violence, were investigated. Contributing factors were compared between the time points. Results: The EE and DA scores were significantly higher in junior residents than in senior residents. Both scores were higher among residents who had experienced abuse or violence. The emergency medicine residents had significantly higher DP scores, while the EE scores of radiology residents were lower than others. Thirty percent of all residents smoked cigarettes. This percentage was even higher among the residents of the departments of surgery and emergency medicine (45-50%). A significant correlation was demonstrated between the scores of MBI and smoking, while analysis with other demographics did not yield any relation. According to the study results, basic science residents had significantly increased scores in all MBI subgroups during the pandemic. Conclusion: Resident physician burnout was found to be related to the work environment, smoking cigarettes and exposure to violence at workplace.

• A pattern shift in SARS-CoV-2 Omicron variant transmission after the city lockdown–observational study based upon daily reported addresses of infected cases -

  Background Varied degrees of lockdown have been imposed for dozens of jurisdictions upon facing the SARS-CoV-2 epidemics during the past two years. Areal lockdown has been demonstrated effective to reduce the morbility and mortality of COVID-19. Even after the strict lockdown the peak of infection will appear around 9-25 days (median 18 days) thereafter. A wave of Omicron variant (BA.2 and BA.2.2) outbreak was seen from March to May 2022, in Shanghai, a megacity in China mainland. Aim To understand the sources of infection cases from outside or inside the isolated locations before and after the strict city lockdown. Methods The attributable addresses of SARS-CoV-2 infection were reported daily as well as the infected cases from March 18th, 2022 on through government website, which was publicly accessible. The address data and infected cases were collected until May 29th, 2022. The location (longitude and latitude) of these addresses were retrieved and the pattern of repeatedly reported addresses were analyzed. A tool of simple and meso-scale point-based (location-based) chronological graph was used to visualize and analyze the interactions of these locations. Results From March 18th to May 29th 2022, 173,350 items representing 35,743 unique addresses and 636,279 infected cases were released. The infection cases peaked 16 days after the city lockdown and were highly clustered in much crowded districts. The proportion of repeatedly reported locations of the previous day increased from around 20% before lockdown to greater than 40% in the plateau and remained at this level for up to one third (20/62) of the lockdown phase. This significantly increased proportion of intra-address infection indicated a pattern shift from inter-addresses to intra-address (D=0.2954, p<0.0001), which might perpetuate to the growth of infection cases. Based upon the day-to-day nearest neighbour transmission assumption the connections between some frequently repeated locations might be complex and heterogeneous. Interpretation During the strict areal isolation the intra-address infection may contribute significantly to infected cases of SARS-CoV-2 Omicron variant, the infection might have easily spilled over the boundary of family(with averaged family size of 2.3-3.1 people and family were required stay-at-home compulsively). This significant inter-addresses to intra-address pattern shift necessitated the understanding of intra-location transmission routes and corresponding interventions. Areal isolation and close off with homogeneous assumption inside and outside the isolated areas should be modified and the quantifing of the elevated risk for previously less exposed but much vulnerable sub-population was in pressing need.

• Epidemiological pattern of births from the largest surveillance database of live births in Brazil “SINASC” before and during the COVID-19 pandemic in the Brazilian Amazon -

  The surveillance of live births in Brazil has been carried out since 1990 by the Information System on Live Births (SINASC), which was implemented by the Ministry of Health aiming at standardized registration on a national level. The state of Para is part of the Brazilian Amazon, northern Brazil, which has several unique characteristics. Thus, the purpose of this study was to identify the epidemiological pattern of live births before and during the pandemic of COVID-19 in the state of Para, 2016 to 2020. This is an ecological epidemiological time-series study, using epidemiological surveillance data from DATASUS, referring to the Live Births Information System (SINASC). These are data that have been treated by surveillance and are in aggregate format. The study population is the live births residing in the state of Para, in the period from 2016 to 2020. The data collection instrument was the Declaration of Live Births (DLB). There were 689,454 live births, and the highest rates of births were and continued to remain in the Marajo II, Baixo Amazonas, Xingu, and Tapajos regions. The Metropolitan I and Araguaia regions were and continue to be the lowest rates in the state. Age of the mother 15 to 19 years old 22.29%, 20 to 24 years old 30.05% and 25 to 29 years old 22.58%, most of the single pregnancy type 98.32%, prenatal consultations, performed 7 or more 48.10%, followed by 4 to 6 consultations 33.98%, most presented 7 or more years of the study 48.10%, followed by 3 to 6 years 33.98%. Represented 51.21% male and 48.77% female. The occurrence of congenital anomalies represented 0.52% of live births. Another congenital malformation and deformity were the most prevalent at 25.53%, followed by Congenital deformities of the feet 14.90%, Other congenital malformations of the nervous system 14.84%, and Other congenital malformations 10.77%, Cleft lip, and cleft palate 8.88%, Other congenital malformations digestive tract 8.10%. The demographic transition has already occurred for several decades, including the reduction of fertility and birth rate, so our study showed that the reduction in the number of live births was already a reality in the country, but we emphasize that this reduction was enhanced by the pandemic. We observed greater adherence to prenatal care and a lower prevalence of low birth weight compared to other studies, but the limitation was the absence of studies in the same place of the research. Regarding data incompleteness, we emphasize the ignored fields that reflect the fragility in the surveillance of live births, which was reinforced by the literature.

• Spatial determination of COVID-19 mortality -

  COVID-19 has affected at the global scale. However, its impacts are not evenly distributed. The article aims to explore the spatial determination of the COVID-19 related death. The data for the analysis has been accessed from the World Health Organization (WHO). Both descriptive and statistical analysis has been done to assess the COVID-19 related death and spatial explanation. The regression models suggested the explanatory power of spatial difference in the COVID-19 related death. However, further addition of various COVID-19 vaccine did not produce expected result.

• Evaluation of QuantiFERON SARS-CoV-2 interferon-γ release assay following SARS-CoV-2 infection and vaccination -

  Background: T cells are important in preventing severe disease from SARS-CoV-2, but scalable and field-adaptable alternatives to expert T cell assays are needed. The interferon-gamma release assay QuantiFERON platform was developed to detect T cell responses to SARS-CoV-2 from whole blood with relatively basic equipment and flexibility of processing timelines. Methods: 48 participants with different infection and vaccination backgrounds were recruited. Whole blood samples were analysed using the QuantiFERON SARS-CoV-2 assay in parallel with the well-established Protective Immunity from T Cells in Healthcare workers (PITCH) ELISpot, which can evaluate spike-specific T cell responses. Aims: The primary aims of this cross-sectional observational cohort study were to establish if the QuantiFERON SARS-Co-V-2 assay could discern differences between specified groups and to assess the sensitivity of the assay compared to the PITCH ELISpot. Findings: The QuantiFERON SARS-CoV-2 distinguished acutely infected individuals (12-21 days post positive PCR) from naive individuals (p< 0.0001) with 100% sensitivity and specificity for SARS-CoV-2 T cells, whilst the PITCH ELISpot had reduced sensitivity (62.5%) for the acute infection group. Sensitivity with QuantiFERON for previous infection was 12.5% (172-444 days post positive test) and was inferior to the PITCH ELISpot (75%). Although the QuantiFERON assay could discern differences between unvaccinated and vaccinated individuals (55-166 days since second vaccination), the latter also had reduced sensitivity (55.5%) compared to the PITCH ELISpot (66.6%). Conclusion: The QuantiFERON SARS-CoV-2 assay showed potential as a T cell evaluation tool soon after SARS-CoV-2 infection but has lower sensitivity for use in reliable evaluation of vaccination or more distant infection.

• Metagenomic next-generation sequencing to characterize etiologies of non-malarial fever in a cohort living in a high malaria burden area of Uganda -

  Background: Causes of non-malarial fevers in sub-Saharan Africa remain understudied. We hypothesized that metagenomic next-generation sequencing (mNGS), which allows for broad genomic-level detection of infectious agents in a biological sample, can systematically identify potential causes of non-malarial fevers. Methods and Findings: The 212 participants in this study were of all ages and were enrolled in a longitudinal malaria cohort in eastern Uganda. Between December 2020 and August 2021, respiratory swabs and plasma samples were collected at 313 study visits where participants presented with fever and were negative for malaria by microscopy. Samples were analyzed using CZ ID, a web-based platform for microbial detection in mNGS data. Overall, viral pathogens were detected at 123 of 313 visits (39%). SARS-CoV-2 was detected at 11 visits, from which full viral genomes were recovered from nine. Other prevalent viruses included Influenza A (14 visits), RSV (12 visits), and three of the four strains of seasonal coronaviruses (6 visits). Notably, 11 influenza cases occurred between May and July 2021, coinciding with when the Delta variant of SARS-CoV-2 was circulating in this population. The primary limitation of this study is that we were unable to estimate the contribution of bacterial microbes to non-malarial fevers, due to the difficulty of distinguishing bacterial microbes that were pathogenic from those that were commensal or contaminants. Conclusions: These results revealed the co-circulation of multiple viral pathogens likely associated with fever in the cohort during this time period. This study illustrates the utility of mNGS in elucidating the multiple causes of non-malarial febrile illness. A better understanding of the pathogen landscape in different settings and age groups could aid in informing diagnostics, case management, and public health surveillance systems.

• Knowledge and Quality of Life of Rural Older Adults during COVID-19 Pandemic -
  Background: The coronavirus (COVID-19) global pandemic negatively affected people’s way of life regardless of age, sex, or ethnicity. This infectious disease is particularly lethal among the elderly, with even higher fatality rates among this age group. Aim of the study: Assess knowledge and quality of life of rural older adults during COVID-19 pandemic. Subjects and Methods: Research design: A descriptive design was utilized. Setting: The study was conducted in a rural area Shobera el nakhla selected randomly from Sharkia Governorate, Egypt. Subjects: Purposive sample composed of 300 older adults aged ≥60 years. Tools of data collection: Three tools were used to collect the study data. Tool I: A structured interview sheet. Tool II: knowledge of the studied older adults about Covid-19. Tool III: WHO Quality of life instrument short form (THE WHOQOL-BREF). Results: among the studied older adults, 68.7% had inadequate knowledge and 51.3% had poor quality of life. Statistically significant relations were found between quality of life and illiteracy, insufficient monthly income, and unmarried status. Conclusion: two-third of older adults had inadequate knowledge and more than half of studied older adults had poor quality of life during covid-19 pandemic. Recommendation: Healthcare Providers should be aware that older individuals were particularly vulnerable to the effects of covid-19 on quality of life and explore strategies to minimize their suffering during the COVID-19 pandemic.

• The COVID-19 pandemic and fertility decline in Costa Rica: A brief plunge due to psychosocial and economic factors and a baby bust driven by migration decisions -
  The national birth registry shows a substantial baby bust in 2021 – the first full year plus nine months into the COVID-19 pandemic. The fertility of native Costa Rican women dropped by 13%. This decrease did not deviate from pre-existing fertility trends. A brief plunge in conceptions during the first full month of the pandemic (April 2020) decreased the fertility rate in January 2021 by as much as 24% for some groups. This plunge was a response to the hardships caused by pandemic mitigation measures as well as uncertainties and fears concerning the novel disease rather than to the physiological harm of the disease itself. The 2021 decrease in births among immigrant women (who contribute one-fifth of the birth rate) was 78% larger than among native women, driven mostly by pandemic-induced migration decisions. The data hint at a pandemic baby boom in low-SES communities and, especially, in families with several children.

• High resolution photocatalytic mapping of SARS-CoV-2 Spike protein-host cell membrane interactions -
  Identifying protein environments at the virus-host cell interface can improve our understanding of viral entry and pathogenesis. SARS-CoV-2, the virus behind the ongoing COVID-19 pandemic, uses the cell surface ACE2 protein as a major receptor, but the contribution of other cellular proteins in the entry process is unknown. To probe the microenvironment of SARS-CoV-2 Spike-ACE2 protein interactomes on human cells, we developed a photocatalyst-based viral-host protein microenvironment mapping platform (ViraMap) employing iridium photocatalysts conjugated to Spike for visible-light driven proximity labelling on host cells. Application of ViraMap on ACE2-expressing cells captured ACE2, the established co-receptor NRP1, as well as other proteins implicated in host cell entry and immunomodulation. We further investigated these enriched proteins via loss-of-function and over-expression in pseudotype and authentic infection models and observed that the Ig receptor PTGFRN and tyrosine kinase ligand EFNB1 can serve as SARS-CoV-2 entry factors. Our results highlight additional host targets that participate infection and showcase ViraMap for interrogating virus-host cell surface interactomes.

• The SARS-CoV-2 accessory protein Orf3a is not an ion channel, but does interact with trafficking proteins -
  The severe acute respiratory syndrome associated coronavirus 2 (SARS-CoV-2) and SARS-CoV-1 accessory protein Orf3a colocalizes with markers of the plasma membrane, endocytic pathway, and Golgi apparatus. Some reports have led to annotation of both Orf3a proteins as a viroporin. Here we show that neither SARS-CoV-2 nor SARS-CoV-1 form functional ion conducting pores and that the conductances measured are common contaminants in overexpression and with high levels of protein in reconstitution studies. Cryo-EM structures of both SARS-CoV-2 and SARS-CoV-1 Orf3a display a narrow constriction and the presence of a basic aqueous vestibule, which would not favor cation permeation. We observe enrichment of the late endosomal marker Rab7 upon SARS-CoV-2 Orf3a overexpression, and co-immunoprecipitation with VPS39. Interestingly, SARS-CoV-1 Orf3a does not cause the same cellular phenotype as SARS-CoV-2 Orf3a and does not interact with VPS39. To explain this difference, we find that a divergent, unstructured loop of SARS-CoV-2 Orf3a facilitates its binding with VPS39, a HOPS complex tethering protein involved in late endosome and autophagosome fusion with lysosomes. We suggest that the added loop enhances SARS-CoV-2 Orf3a ability to co-opt host cellular trafficking mechanisms for viral exit or host immune evasion.

• Plant production of high affinity nanobodies that block SARS-CoV-2 spike protein binding with its receptor, human angiotensin converting enzyme -
  Nanobodies (VHH antibodies), are small peptides that represent the antigen binding domain, VHH of unique single domain antibodies (heavy chain only antibodies, HcAb) derived from camelids. Here, we demonstrate production of VHH nanobodies against the SARS-CoV-2 spike proteins in the solanaceous plant Nicotiana benthamiana through transient expression and their subsequent detection verified through western blot. We demonstrate that these nanobodies competitively inhibit binding between the SARS-CoV-2 spike protein receptor binding domain and its human receptor protein, angiotensin converting enzyme 2 (ACE2). We present plant production of nanobodies as an economical and scalable alternative to rapidly respond to therapeutic needs for emerging pathogens in human medicine and agriculture.

• Rapid Identity and Quantity CQA Test for Multivalent mRNA Drug Product Formulations -
  The COVID-19 pandemic highlighted mRNA as a promising platform for vaccines and therapeutics. Many of the analytical tools used to characterize the critical quality attributes of mRNA are inherently singleplex and are not necessarily optimal from a labor and cost perspective. Here we demonstrate feasibility of a multiplexed platform (VaxArray) for efficient identity verification and concentration determination for both monovalent and multivalent mRNA formulations. A model system comprised of mRNA constructs for influenza hemagglutinin and neuraminidase was used to characterize the analytical performance metrics for a VaxArray mRNA assay. The assay presented herein had a time to result of less than 2 hours, required no PCR-based amplification nor extraction of mRNA from lipid nanoparticles, and exhibited high construct specificity that enabled application to the bivalent mixture. The sensitivity for influenza hemagglutinin and neuraminidase mRNA was sub-/mL, which is vaccine-relevant, and the average accuracy (%recovery) and precision were 104%{+/-}2%and 9%{+/-}2%, respectively.

Methods: Human LMs were isolated from patients operated on for lung carcinoma. The LMs were cultured with ruxolitinib…

• Nutraceutical prospects of Houttuynia cordata against the infectious viruses - The novel enveloped β-coronavirus SARS-CoV-2 (COVID-19) has offered a surprising health challenge all over the world. It develops severe pneumonia leading to acute respiratory distress syndrome (ARDS). Like SARS-COV-2, other encapsulated viruses like HIV, HSV, and influenza have also offered a similar challenge in the past. In this regard, many antiviral drugs are being explored with varying degrees of success to combat the associated pathological conditions. Therefore, upon scientific…

• A DNA-based non-infectious replicon system to study SARS-CoV-2 RNA synthesis - The COVID-19 pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has seriously affected public health around the world. In-depth studies on the pathogenic mechanisms of SARS-CoV-2 is urgently necessary for pandemic prevention. However, most laboratory studies on SARS-CoV-2 have to be carried out in BSL-3 laboratories, greatly restricting the progress of relevant experiments. In this study, we used a bacterial artificial chromosome (BAC) method to assemble a…

• The mechanism of metal-based antibacterial materials and the progress of food packaging applications: A review - Food packages have been detected carrying novel coronavirus in multi-locations since the outbreak of COVID-19, causing major concern in the field of food safety. Metal-based supported materials are widely used for sterilization due to their excellent antibacterial properties as well as low biological resistance. As the principal part of antibacterial materials, the active component, commonly referred to Ag, Cu, Zn, etc., plays the main role in inhibiting and killing pathogenic microorganisms by…

• Heterologous Prime-boost of SARS-CoV-2 Inactivated Vaccine and mRNA BNT162b2 among Healthy Thai Adolescents - CONCLUSIONS: Heterologous prime-boost vaccination with CoronaVac followed by BNT162b2 induced high neutralizing titer against SARS-CoV-2 Delta strain. After 5-month interval, booster with BNT162b2 induced high neutralizing titer against Omicron strain.Thai Clinical Trials Registry (thaiclinicaltrials.org): TCTR20210923012.

• Mechanism of selenomethionine inhibiting of PDCoV replication in LLC-PK1 cells based on STAT3/miR-125b-5p-1/HK2 signaling - There are no licensed therapeutics or vaccines available against porcine delta coronavirus (PDCoV) to eliminate its potential for congenital disease. In the absence of effective treatments, it has led to significant economic losses in the swine industry worldwide. Similar to the current coronavirus disease 2019 (COVID-19) pandemic, PDCoV is trans-species transmissible and there is still a large desert for scientific exploration. We have reported that selenomethionine (SeMet) has potent antiviral…

• Semi-selective plasma filtration applied to the treatment of acquired thrombotic thrombocytopenic purpura following bnt162b2 administration - Following the widespread use of anti SARS-CoV-2 vaccines, there have been reports of thrombocytopenia developing after the administration of different types of vaccine. We report a case of a 63-year-old male who developed neurological symptoms after receiving the second dose of the bnt162b2 vaccine. Blood tests performed upon admission to the Emergency Department revealed severe thrombocytopenia and microangiopathic hemolytic anemia. ADAMTS13 activity was undetectable and antibody titer was…

• Native and activated antithrombin inhibits TMPRSS2 activity and SARS-CoV-2 infection - Host cell proteases such as TMPRSS2 are critical determinants of SARS-CoV-2 tropism and pathogenesis. Here, we show that antithrombin (AT), an endogenous serine protease inhibitor regulating coagulation, is a broad-spectrum inhibitor of coronavirus infection. Molecular docking and enzyme activity assays demonstrate that AT binds and inhibits TMPRSS2, a serine protease that primes the Spike proteins of coronaviruses for subsequent fusion. Consequently, AT blocks entry driven by the Spikes of…

• Dipeptidylpeptidase (DPP)-4 inhibitor therapy increases circulating levels of anti-inflammatory soluble frizzle receptor protein (sFRP)-5 which is decreased in severe COVID-19 disease - Obesity and type 2 diabetes (T2D) show an increased risk for a severe COVID-19 disease. Treatment with DPP4 inhibitor (DPP4i) results in reduced mortality and better clinical outcome. Here, we aimed to identify potential mechanisms for the observed DPP4i effect in COVID-19. Comparing T2D subjects with and without DPP4i treatment, we identified a significant increase of the anti-inflammatory adipokine sFRP5 in relation to DPP4 inhibition. sFRP5 is a specific antagonist to Wnt5a, a glycopeptide…
