Media and scientific communication about the COVID-19 pandemic and the repercussions on the population's mental health

Abstract Background: Good communication strategies are essential in times of crisis, such as the coronavirus pandemic. The dissemination of inaccurate information and the need for social isolation to control coronavirus disease 2019 (COVID-19) have shown a negative impact on the population, causing damage to mental health, with the appearance or worsening of symptoms of stress, fear, anxiety, and depression. Thus, the systematic review study is intended to gather evidence on the impact of information about COVID-19 on the mental health of the population. Methods: This systematic review protocol is conducted using the guidelines of the preferred reporting items for systematic reviews and meta-analyses protocols and the Cochrane Handbook for Systematic Reviews of Interventions. The review aims to include published studies that address the exposure of the general population to information about COVID-19, through observational and experimental studies, which consider the following outcomes: fear, stress, anxiety, and depression. Thus, a comprehensive research strategy will be conducted in the following databases: PubMed / Medline, Scopus, Web of Science, EMBASE, Science Direct, CINAHL, PsycINFO and Cochrane Central Register of Controlled Trials (CENTRAL). Two independent reviewers will perform all procedures, such as study selection, data collection, and methodological evaluation. Disagreements will be forwarded to a third reviewer. RevMan 5.3 software will be used for data analysis. Results: This systematic review will provide evidence of the influence of access to and consumption of media and scientific information about COVID-19 on the mental health of the population. It will consider information about the characterization of the study and the population studied, clinical and epidemiological information on mental health, and data on access to and consumption of media and scientific information. Discussion: The results should inform about the consequences of communication about the new coronavirus on the emergence or worsening of psychological and psychiatric symptoms, allowing to develop strategies to achieve effective communication of information to promote the mental health of the population.

Using high-resolution melting to identify Calliphoridae (blowflies) species from Brazil

Forensic entomology is the study of insects and other arthropods used in the solution of crimes. Most of entomological evidences strongly depend on accurate species identification. Therefore, new methods are being developed due to difficulties in morphological identification, including molecular methods such as High-Resolution Melting. In this study, we reported a new HRM primer set to identify forensically important Calliphoridae (blowflies) from Brazil. For such purpose, Calliphoridae species of forensic importance in Brazil were listed and confirmed by specialists. Mitochondrial COI sequences of those species were downloaded from databases and aligned, and polymorphic variations were selected for distinction between species. Based on it, HRM primers were designed. Forty-three fly samples representing six species were tested in the HRM assay. All samples had the COI gene sequenced to validate the result. Identifying and differentiating the six species proposed using a combination of two amplicons was possible. The protocol was effective even for old insect specimens, collected and preserved dried for more than ten years, unlike the DNA sequencing technique that failed for those samples. The HRM technique proved to be an alternative tool to DNA sequencing, with advantage of amplifying degraded samples and being fast and cheaper than the sequencing technique.
Irreversible Photobleaching of the Solution of Fluorescent Dyes. V. Photobleaching of Erythrosin

Photobleaching of the aqueous alcoholic erythrosin solutions in air and in vacuo was investigated. In general, erythrosin showed behavior similar to eosin. An excited dye molecule which participates in the primary processes is the long-lived species, having a lifetime of the order of 10−7sec. It was concluded that the primary process in aerobic aqueous erythrosin solution proceeds via the process, D+O2→D······O2, as in the case of eosin. It was found that excited erythrosin is somewhat more reactive than excited eosin towards dissolved oxygen, while it is less reactive towards alcohols in vacuo. Some quantitative values on the reactivities were given.
Stiff-person syndrome coexisting with critical illness polyneuropathy

Abstract Rationale: Stiff-person syndrome (SPS) is an uncommon neurological disorder with autoimmune features. Here, we report a 60-year-old man with SPS associated with critical illness polyneuropathy (CIP). CIP was diagnosed during an episode of acute respiratory failure secondary to muscular rigidity and spasms, which has rarely been reported in this condition. The overlapping of CIP and SPS complicated the case. Patient concerns: A 60-year-old man presented with gradual onset of cramps, stiffness, and rigidity in his lower limbs 1 year before admission, which eventually led to inability to stand and walk. The persistent nature of his symptoms progressed to frequent acute episodes of dyspnea and he was admitted to intensive care unit (ICU). Diagnosis: SPS had been diagnosed after 2 tests of electromyography (EMG) and the detection of an elevated anti-GAD65 antibody titer. During the first EMG, low or absent compound muscle action potentials (CMAP), and sensory nerve action potentials (SNAP) were shown. Therefore, the diagnosis of SPS coexisting with CIP was made. Interventions: Symptomatic treatment was initiated with oral clonazepam (0.5 mg Bid) and baclofen (5 mg Bid). Intravenous immunoglobulin (IVIG) (0.4 g/kg/d) was administered for the patient for 5 days after admission. We observed a significant clinical improvement during the administration period, and the patient became ambulatory. Outcomes: On follow-up, the patient reported complete relief of his pain and rigidity. Lessons: We report this special case to address the varied clinical features of SPS. Electrophysiological testing is an important diagnostic approach. Accurate recognition of the disease ensures that the patients can be given appropriate treatment without delay.
Vertical Guided Bone Regeneration in the Rabbit Calvarium Using Porous Nanohydroxyapatite Block Grafts Coated with rhVEGF165 and Cortical Perforation

Introduction Vertical bone augmentation without osseous walls to support the stability of clots and bone grafts remains a challenge in dental implantology. The objectives of this study were to confirm that cortical perforation of the recipient bed is necessary and to evaluate whether nanohydroxyapatite (nHA) block grafts coated with recombinant human vascular endothelial growth factor165 (rhVEGF165) and cortical perforation can improve vertical bone regeneration. Materials and Methods We prepared nHA blocks coated with or without rhVEGF165 on the rabbit calvarium through cortical perforation, and designated the animals as the nonperforated group (N-nHA), rhVEGF165 group (NV-nHA), perforated group (P-nHA) and rhVEGF165 on perforated group (PV-nHA). Micro-computed tomography (micro-CT) and fluorescence microscopy were selected to evaluate parameters of vertical bone regeneration at 4 and 6 weeks. Results The ratio of the newly formed bone volume to the titanium dome volume (BV/TV) and the bone mineral density (BMD) were significantly higher in the PV-nHA group than in the N-nHA group at 4 and 6 weeks, as determined using micro-CT. The fluorescence analysis showed slightly greater increases in new bone regeneration (NB%) and vertical height (VH%) gains in the P-nHA group than in the N-nHA group. Greater increases in NB% and VH% were observed in groups treated with rhVEGF165 and perforation than in the blank groups, with significant differences detected at 4 and 6 weeks (N-nHA compared with PV-nHA, p<0.05). A greater VH% that was observed at the midline of the block in the PV-nHA group than in the other three groups at both time points (0.75±0.53% at 4 weeks and 0.83±0.42% at 6 weeks). Conclusion According to the present study, cortical perforation is necessary and nHA blocks coated with rhVEGF165 and decoration could work synergistically to improve vertical bone regeneration by directly affecting primary osteoblasts and promoting angiogenesis and osteoinduction.
Community Pharmacists’ Views of the Enforced Antibiotics Dispensing Law and Its Impact on Oral Antibiotics Sales in Saudi Arabia

Objective(s) The aim of this study was to explore community pharmacists’ views toward the antibiotics dispensing law that was enforced in May 2018 and bans the sale of antibiotics without a prescription in community pharmacy settings in Saudi Arabia. Moreover, the potential impact of the law enforcement on the sales of oral antibiotics in Saudi Arabia was also explored. Methods A questionnaire-based cross-sectional study was conducted between September 2019 and March 2020 in Riyadh, Saudi Arabia. A multistage sampling technique was used to recruit community pharmacists from different districts. Pharmacists who consented to participate and reported practicing prior to the law enforcement were interviewed about their views of the law using a 14-item newly developed questionnaire. The annual sales of oral antibiotics for the years of 2017, 2018, and 2019 were retrieved from the Saudi Food and Drug Authority (SFDA) database. Results Two hundred and eighty six pharmacists consented to participate and met the inclusion criteria. After the law enforcement, approximately 51% of the participants reported that the percentage of patients seeking antibiotics without a prescription is less than 25%. Moreover, the majority (87.41%) reported a drop in the sales of antibiotics. Additionally, about 90% of the participants believed that the rate of inappropriate use of antibiotics will decrease as a result of the law enforcement. About 41% of the participants reported that the law has negatively impacted their pharmacies’ profits. The sales of oral antibiotics have seen a 16.6% drop in the year of 2019 as compared to 2017. Conclusion The antibiotics dispensing law is favorably perceived among community pharmacists in Saudi Arabia despite some concerns about its impact on their sales. Exploring different business models that delink the profits from the volume of antibiotics sales is necessary for this vital industry to thrive.
Risk factors associated with relapse of adult-onset Still disease in Korean patients

Abstract Approximately 30% to 40% of all patients with adult-onset Still disease (AOSD) experience relapses, sometimes presenting as chronic damage, and these events can subsequently increase the morbidity and mortality in patients with AOSD. However, few studies are investigating the factors related to relapse in such patients. Therefore, this study aimed to explore the risk factors associated with relapse of AOSD. This cohort study enrolled 112 AOSD patients who satisfied the Yamaguchi criteria and obtained available data from Chonnam National University Hospital. The demographic, clinical, and laboratory data as well as treatment history of the patients from January 2008 to December 2019 were retrospectively reviewed. Relapse events were defined as the presence of one or more recurrent events. Multivariate logistic regression analysis was performed to investigate the possible risk factors for relapse. During a mean follow-up of 103.3 months, 47 of 112 patients (41.9%) developed a relapse. According to the results of multivariate logistic regression analysis, arthritis (odds ratio [OR] = 19.530, 95% confidence interval [CI]: 5.047–75.582, P < .001) and lymphadenopathy (OR = 6.539, 95% CI: 2.329–18.358, P < .001) predicted the development of recurrent events in patients with AOSD. Patients with AOSD had frequent relapses during the clinical course of their disease. Risk factors associated with flares were the presence of arthritis and lymphadenopathy.
Antenatal Care Service Utilization of Pregnant Women Attending Antenatal Care in Public Hospitals During the COVID-19 Pandemic Period

Background The recent coronavirus disease (COVID-19) pandemic has had a disastrous effect on the health-care delivery system, of mainly pregnancy-related healthcare. In order to fill the information gap in the scientific literature and in response to the limited evidence in the country, this study aims to assess the impact of the COVID-19 pandemic on antenatal care utilization among pregnant women attending public facilities in Northeast Ethiopia. Therefore, the result will be beneficial to design strategies for prioritizing maternal healthcare even with the COVID-19 pandemic period. Methods A facility-based cross-sectional study was conducted from February 2 to August 30, 2020 among pregnant women attending ANC services at public hospitals in Northeast Ethiopia. Thus, a total of 389 women were included in the study with a simple random sampling technique. The bi-variable and multi-variable logistic regression models were employed to identify factors significantly associated with ANC utilization. Adjusted odds ratio (AOR) with 95% CI was estimated to show the strength of association. Finally, a P-value of <0.05 in the multivariable logistic regression analysis was used to identify predictors of antenatal care utilization. Results Overall, 114 (29.3%) pregnant women had fully utilized antenatal care services during the pandemic period. Mother age ≥35 years (AOR=11.79, 95% CI=1.18– 117.8), secondary education and above (AOR=4.74, 95% CI=1.04– 21.61), history of stillbirth before recent pregnancy (AOR=0.007, 95% CI=0.001–0.12), interruption and diversion of services due to COVID-19 response (AOR=0.675, 95% CI=0.142–0.742), fear of COVID-19 (AOR=0.13, 95% CI=0.06–0.31), and lack of transport access (AOR=4.15, 95% CI=1.04–16.54) were predictors of full antenatal care service utilization. Conclusion Three of every ten pregnant women who attended the obstetric outpatient clinics have fully utilized the antenatal care services. Encouraging women’s educational status, prioritizing maternal health services during COVID-19, and improving the quality of ANC service should be emphasized more.
Heterotrimeric G proteins promote FLS2 protein accumulation through inhibition of FLS2 autophagic degradation

FLAGELLIN-SENSITIVE 2 (FLS2) is a plant immune receptor that binds bacterial flagellin to activate immune signaling. This immune signal is transduced by a heterotrimeric G protein complex at the plasma membrane and activates downstream signaling. However, it is unknown whether the heterotrimeric G proteins have functions at other subcellular locations away from the plasma membrane. Here, we show that components of the heterotrimeric G protein complex stabilize FLS2 protein levels by inhibiting the autophagic degradation of FLS2. Using genetic analysis, we determined that mutations of G protein components resulted in reduced immune signaling in part due to decreased FLS2 protein levels. Furthermore, reduction of FLS2 protein levels was caused by elevated proteasomal and autophagic degradation of FLS2. Genetic inhibition of autophagy in G protein mutants rescued FLS2 levels and immunity. Our findings suggest that the heterotrimeric G protein components, in addition to being part of the heterotrimeric G protein complex that transduces signals at the plasma membrane, also function away from the plasma membrane to control FLS2 protein levels. These results expand the functional capacity of the heterotrimeric G protein complexes in plant immunity.
Reconstruction of Bony Defects after Tumor Resection with 3D-Printed Anatomically Conforming Pelvic Prostheses through a Novel Treatment Strategy

There has been an increasing interest and enormous applications in three-dimensional (3D) printing technology and its prosthesis, driving many orthopaedic surgeons to solve the difficult problem of bony defects and explore new ways in surgery approach. However, the most urgent problem is without an effective prosthesis and standard treatment strategy. In order to resolve these problems, this study was performed to explore the use of a 3D-printed anatomically conforming pelvic prosthesis for bony defect reconstruction following tumor resection and to describe a detailed treatment flowchart and the selection of a surgical approach. Six patients aged 48-69 years who had undergone pelvic tumor resection underwent reconstruction using 3D-printed anatomically conforming pelvic prostheses according to individualized bony defects between March 2016 and June 2018. According to the Enneking and Dunham classification, two patients with region I+II tumor involvement underwent reconstruction using the pubic tubercle-anterior superior iliac spine approach and the lateral auxiliary approach and one patient with region II+III and three patients with region I+II+III tumor involvement underwent reconstruction using the pubic tubercle-posterior superior iliac spine approach. The diagnoses were chondrosarcoma and massive osteolysis. After a mean follow-up duration of 30.33 ± 9.89 months (range, 18-42), all patients were alive, without evidence of local recurrence or distant metastases. The average blood loss and blood transfusion volumes during surgery were 2500.00 ± 1461.51 ml (range, 1200-5000) and 2220.00 ± 1277.62 ml (range, 800-4080), respectively. During follow-up, the mean visual analogue scale (VAS) score decreased, and the mean Harris hip score increased. There were no signs of hip dislocation, prosthetic loosening, delayed wound healing, or periprosthetic infection. This preliminary study suggests the clinical effectiveness of 3D-printed anatomically conforming pelvic prostheses to reconstruct bony defects and provide anatomical support for pelvic organs. A new surgical approach that can be used to expose and facilitate the installation of 3D-printed prostheses and a new treatment strategy are presented. Further studies with a longer follow-up duration and larger sample size are needed to confirm these encouraging results.
Intravenous Administration of Vitamin C in the Treatment of Herpes Zoster-Associated Pain: Two Case Reports and Literature Review

Background Herpes zoster (HZ) is an acute inflammatory neurocutaneous disease caused by the reactivation of varicella-zoster virus. It is estimated that the incidence of postherpetic neuralgia following HZ is 10–20%. The leading risk factors of the prognosis are aging and immunity dysfunction. Vitamin C plays a pivoted role in enhancing white blood cell function. Epidemiological evidence and clinical studies have indicated an association between pain and suboptimal vitamin C status. At present, vitamin C has been used as an additional option in the treatment of HZ-associated pain. Despite the current controversy, case reports and randomized controlled studies have indicated that both acute- and postherpetic neuralgia can be dramatically alleviated following intravenous vitamin C infusions. Case Presentation. Two patients (male aged 72 and female 78 years) with HZ did not respond well to antiviral therapy and analgesics. Skin lesions in the right groin and front thigh healed after early antiviral therapy, but the outbreak of pain persisted in the male patient. The female patient presented to our clinic with clusters of rashes in the right forehead with severe edema of her right upper eyelid. Because nerve blockade could not be conducted for both patients, intravenous infusion of vitamin C was applied and resulted in an immediate remission of the breakthrough pain in the male patient and cutaneous lesions in the female patient. Conclusions The use of vitamin C appears to be an emerging treatment alternative for attenuating HZ and PHN pain. Hence, we recommend the addition of concomitant use of intravenously administered vitamin C into therapeutic strategies in the treatment of HZ-associated pain, especially for therapy-resistant cases. Furthermore, animal studies are required to determine analgesic mechanisms of vitamin C, and more randomized clinical trials are essential to further determine the optimal dose and timing of administration of vitamin C.
Live Experiences of Adolescent Mothers Attending Mbale Regional Referral Hospital: A Phenomenological Study

Background Adolescence is a period of transition from childhood to adulthood, and is a critical stage in ones' development. It is characterized by immense opportunities and risks. By 2016, 16% of the world's population was of adolescents, with 82% residing in developing countries. About 12 million births were in 15–19 year olds. Sub-Saharan Africa, particularly East Africa, has high adolescent pregnancy rates, as high as 35.8% in eastern Uganda. Maternal mortality ratio (MMR) attributable to 15–19 years olds is significant with 17.1% of Uganda's MMR 336/100.000 live births being in this age group. Whereas research is awash with contributing factors to such pregnancies, little is known about lived experiences during early motherhood. This study reports the lived experiences of adolescent mothers attending Mbale Hospital. Materials and Methods A phenomenological study design was used in which adolescent mothers that were attending Young Child Clinic were identified from the register and simple random sampling was used to select participants. We called these mothers by way of phone numbers and asked them to come for focus group discussions that were limited to 9 mothers per group and lasting about 45 minutes–1 hour. Ethical approval was sought and informed written consent obtained from participants. At every focus group discussion, the data which had largely been taken in local languages was transcribed and translated verbatim into English. Results The research revealed that adolescent mothers go through hard times especially with the changes of pregnancy and fear of unknown during intrapartum and immediate postpartum period and are largely treated negatively by family and other community members in addition to experiencing extreme hardships during parenting. However, these early mothers' stress is alleviated by the joy of seeing their own babies. Conclusion Adolescent motherhood presents a high risk group and efforts to support them during antenatal care with special adolescent ANC clinics and continuous counseling together with their household should be emphasized to optimize outcome not only during pregnancy but also thereafter. Involving these mothers in technical courses to equip them with skills that can foster self-employment and providing support to enable them pursue further education should be explored.
Human Bone Marrow Mesenchymal Stem/Stromal Cells Exposed to an Inflammatory Environment Increase the Expression of ICAM-1 and Release Microvesicles Enriched in This Adhesive Molecule: Analysis of the Participation of TNF-α and IFN-γ

Bone marrow mesenchymal stem/stromal cells (BM-MSCs) have immunoregulatory capacity; therefore, they have been used in different clinical protocols in which it is necessary to decrease the immune response. This capacity is mainly regulated by TNF-α and IFN-γ, and it has been observed that cell-cell contact, mainly mediated by ICAM-1, is important for MSCs to carry out efficient immunoregulation. Therefore, in the present work, we analyzed the effect of TNF-α alone or in combination with IFN-γ on the expression of ICAM-1. Besides, given the importance of cell contact in the immunoregulatory function of MSCs, we analyzed whether these cells release ICAM-1+ microvesicles (MVs). Our results show for the first time that TNF-α is capable of increasing the early expression of ICAM-1 in human BM-MSCs. Also, we observed that TNF-α and IFN-γ have a synergistic effect on the increase in the expression of ICAM-1. Furthermore, we found that BM-MSCs exposed to an inflammatory environment release MVs enriched in ICAM-1 (MVs-ICAM-1high). The knowledge generated in this study will contribute to the improvement of in vitro conditioning protocols that favor the therapeutic effect of these cells or their products.
