Rhinoplasty Health Inventory and Nasal Outcomes (RHINO) Scale: Translation, Cross-Cultural Adaptation and Validation for Hebrew-Speaking Patients.

Patient-reported outcomes questionnaires are accepted measurement tools to evaluate procedures results. The Rhinoplasty Health Inventory and Nasal Outcomes (RHINO) scale is an English-language validated and reliable quality-of-life instrument that evaluates both functional and aesthetic outcomes after rhinoplasty, and is not available in Hebrew. We followed the forward-and-back-translation method, defined by the European Organization for Research and Treatment of Cancer. Translation of the RHINO scale and merging it into one version were performed, following back-translation and validation on native Hebrew-speaking patients who underwent rhinoplasty and control healthy group. Lastly, we review and analyzed the results. The translated questionnaire had high reliability measures, demonstrating homogeneity (α value 0.800 in the rhinoplasty group and 0.896 in the control group), test-retest reproducibility with no significant difference (p = 0.5), and high agreement scores represented by the Bland-Altman plot (95% limits of agreement ranged from 8.78 to 9.80). Validity demonstrated by significant differences between the two study groups' mean questionnaire scores (p < 0.001 for rhinoplasty vs. controls, p < 0.001 for preoperative vs. postoperative, and p = 0.002 for postoperative vs. control group) and also between the aesthetic scores and functional scores of the rhinoplasty group before and after the surgery (p < 0.001). There were no reported understanding problems. The Hebrew version of the RHINO scale is a reliable and valid tool for pre- and post-rhinoplasty surgery outcomes measuring among Hebrew-speaking patients, and can improve coordination of expectations, follow-up, and quantify subjective evaluation of the surgery. Level of evidence: IV.

Long-term outcomes after pre-emptive liver transplantation in primary hyperoxaluria type 1.

BACKGROUND: Primary hyperoxaluria type 1 (PH1) is an autosomal recessive disease caused by the liver defect of oxalate metabolism, which leads to kidney failure and systemic manifestations. Until recently, liver transplantation was the only definitive treatment. The timing of liver transplantation can be early, while kidney function is still normal (pre-emptive liver transplantation-PLT), or when the patient reaches stage 5 chronic kidney disease (CKD) and needs combined liver-kidney transplantation. We aimed to determine the long-term kidney outcomes of PLT in PH1 patients. METHODS: A retrospective single-center study of PH1 patients who were followed in our center between 1997 and 2017. We compared the kidney outcomes of patients who underwent PLT to those who presented with preserved kidney function and did not undergo PLT. RESULTS: Out of 36 PH1 patients, 18 patients were eligible for PLT (eGFR > 40 mL/min/1.73 m2 at the time of diagnosis). Seven patients underwent PLT (PLT group), while 11 continued conservative treatments (PLTn group). In the PLT group, the median eGFR at the time of PLT and at the end of the follow-up period (14-20 years) was 72 (range 50-89) and 104 (range 86-108) mL/min/1.73 m2, respectively, and no patient died or reached stage 5 CKD. In the PLTn group, eight patients (72.7%) reached stage 5 CKD (median time to kidney replacement therapy was 11 years), and two patients died from disease complications (18.2%). CONCLUSIONS: Pre-emptive liver transplantation preserved kidney function in patients with PH1 in our cohort. Early intervention can prevent kidney failure and systemic oxalosis in PH1.

Maternal and Cord Anti-SARS-CoV-2-Spike IgG following COVID-19 Vaccination versus Infection during Pregnancy: A Prospective Study, Israel October 2021-March 2022.

OBJECTIVE: Defining how pregnant women respond to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and vaccination is critical to optimize vaccination strategies that protect mother and infant at the epidemic. This study aimed to compare anti-SARS-CoV-2-spike immunoglobulin G (IgG) of vaccinated versus infected women and to determine the optimal timing of maternal vaccination during pregnancy at the time of epidemic. STUDY DESIGN: We collected maternal/cord blood at delivery (October 2021-March 2022) and measured anti-SARS-CoV-2-spike IgG geometric mean concentrations (IgG-GMCs) using a quantitative immunoassay. We compared groups according to timing and number of doses and correlated maternal and fetal IgG levels. We described the proportion of women with IgG levels above the 150 AU/mL positivity threshold according to the timing of infection/vaccination and performed a subanalysis for maternal IgG-GMC levels pre- and during the Omicron wave. RESULTS: We included 238 vaccinated women, 125 who received two doses and 113 three doses, and 48 unvaccinated infected women. All groups infected/vaccinated in the second or third trimester had an IgG-GMC above the positivity threshold. Third-trimester vaccination (second/third dose) resulted in higher maternal and cord-blood IgG-GMC compared to the second trimester (maternal-IgG: 102,32 vs. 4,325 AU/mL, p < 0.001; cord-IgG: 12,113 vs. 8,112 AU/mL, p < 0.001). Compared with infected-only women, a higher proportion of vaccinated women with ≥2 doses and their newborns had IgG levels above the positivity threshold at all time points. In vaccinated women, there were higher maternal IgG-GMC levels during the Omicron wave than pre-Omicron. CONCLUSION: At the time of epidemic, receiving an additional COVID-19 vaccine dose in the third trimester resulted in a higher IgG-GMC compared to the second trimester. Relatively higher levels of maternal and cord IgG-GMC were achieved following vaccination than infection. Women infected during or before the first trimester might benefit from an additional third-trimester dose to prevent peripartum infection and to passively immunize their newborn. The higher levels of maternal IgG-GMC in the Omicron period are suggestive of hybrid immunity. KEY POINTS: · Higher maternal anti-SARS-IgGs in vaccinated → infected.. · Higher cord anti-SARS-IgGs in vaccinated → infected.. · Third-trimester vaccine resulted in high-cord IgG levels..

[SPONTANEOUS CEREBROSPINAL FLUID LEAK OF THE TEMPORAL BONE].

INTRODUCTION: Spontaneous cerebrospinal fluid (CSF) leak into the temporal air spaces is a prominent risk factor for meningitis, often leading to debilitating neurological morbidities and even death. CSF leaks may arise due to trauma, congenital malformation, or surgery, but in most cases, they develop spontaneously. In spontaneous CSF leaks, no obvious triggering event is apparent in the patient's clinical history that points to this diagnosis, in contrast to some of the other etiologies. The clinical presentation of spontaneous CSF leaks is not unique and is characterized by patients' complaints, such as hearing loss and aural fullness. These symptoms are commonly associated with prevalent conditions, such as serous otitis media. For these reasons, a typical diagnostic delay of spontaneous CSF leaks, which can last for years in some cases, leaves the patients exposed to meningeal infection without being offered an efficient surgical treatment to keep them safe and protected.

COVID-19 classification of X-ray images using deep neural networks.

OBJECTIVES: In the midst of the coronavirus disease 2019 (COVID-19) outbreak, chest X-ray (CXR) imaging is playing an important role in diagnosis and monitoring of patients with COVID-19. We propose a deep learning model for detection of COVID-19 from CXRs, as well as a tool for retrieving similar patients according to the model's results on their CXRs. For training and evaluating our model, we collected CXRs from inpatients hospitalized in four different hospitals. METHODS: In this retrospective study, 1384 frontal CXRs, of COVID-19 confirmed patients imaged between March and August 2020, and 1024 matching CXRs of non-COVID patients imaged before the pandemic, were collected and used to build a deep learning classifier for detecting patients positive for COVID-19. The classifier consists of an ensemble of pre-trained deep neural networks (DNNS), specifically, ReNet34, ReNet50¸ ReNet152, and vgg16, and is enhanced by data augmentation and lung segmentation. We further implemented a nearest-neighbors algorithm that uses DNN-based image embeddings to retrieve the images most similar to a given image. RESULTS: Our model achieved accuracy of 90.3%, (95% CI: 86.3-93.7%) specificity of 90% (95% CI: 84.3-94%), and sensitivity of 90.5% (95% CI: 85-94%) on a test dataset comprising 15% (350/2326) of the original images. The AUC of the ROC curve is 0.96 (95% CI: 0.93-0.97). CONCLUSION: We provide deep learning models, trained and evaluated on CXRs that can assist medical efforts and reduce medical staff workload in handling COVID-19. KEY POINTS: • A machine learning model was able to detect chest X-ray (CXR) images of patients tested positive for COVID-19 with accuracy and detection rate above 90%. • A tool was created for finding existing CXR images with imaging characteristics most similar to a given CXR, according to the model's image embeddings.

Vaccine hesitancy due to vaccine country of origin, vaccine technology, and certification.

Vaccine hesitancy is a global health threat which may hinder the widespread acceptance of several COVID-19 vaccines. Following the collection of 2470 responses from an anonymous questionnaire distributed between October and November 2020 across Israel, we analyzed the responses of physicians, life science graduates (biology, virology, chemistry, etc.), and the general public to whether they would obtain a COVID-19 vaccine with particular vaccine characteristics such as vaccine country of origin, technology, side effect profile, efficacy, and other attributes. Physicians and life science graduates were least likely to accept a vaccine based on mRNA technology (30%) while the general population seemed to adopt any vaccine technology if the declared efficacy is above 90% and the country of manufacturing is the USA/UK rather than China or Russia. However, current inoculation rates in Israel far outpace our predicted rate. Our results highlight the importance of tailored vaccine educational campaigns based on population demographic details and specific vaccine concerns.

Vaccine hesitancy: the next challenge in the fight against COVID-19.

Vaccine hesitancy remains a barrier to full population inoculation against highly infectious diseases. Coincident with the rapid developments of COVID-19 vaccines globally, concerns about the safety of such a vaccine could contribute to vaccine hesitancy. We analyzed 1941 anonymous questionnaires completed by healthcare workers and members of the general Israeli population, regarding acceptance of a potential COVID-19 vaccine. Our results indicate that healthcare staff involved in the care of COVID-19 positive patients, and individuals considering themselves at risk of disease, were more likely to self-report acquiescence to COVID-19 vaccination if and when available. In contrast, parents, nurses, and medical workers not caring for SARS-CoV-2 positive patients expressed higher levels of vaccine hesitancy. Interventional educational campaigns targeted towards populations at risk of vaccine hesitancy are therefore urgently needed to combat misinformation and avoid low inoculation rates.

Hearing loss: mechanisms revealed by genetics and cell biology.

Hearing loss (HL), or deafness in its most severe form, affects an estimated 28 and 22.5 million Americans and Europeans, respectively. The numbers are higher in regions such as India and the Middle East, where consanguinity contributes to larger numbers of recessively inherited hearing impairment (HI). As a result of work-related difficulties, educational and developmental delays, and social stigmas and exclusion, the economic impact of HL is very high. At the other end of the spectrum, a rich deaf culture, particularly for individuals whose parents and even grandparents were deaf, is a social movement that believes that deafness is a difference in human experience rather than a disability. This review attempts to cover the remarkable progress made in the field of the genetics of HL over the past 20 years. Mutations in a significant number of genes have been discovered over the years that contribute to clinically heterogeneous forms of HL, enabling genetic counseling and prediction of progression of HL. Cell biological assays, protein localization in the inner ear, and detailed analysis of spontaneous and transgenic mouse models have provided an incredibly rich resource for elucidating mechanisms of hereditary hearing loss (HHL). This knowledge is providing answers for the families with HL, who contribute a great deal to the research being performed worldwide.

Atrophic thyroid follicles and inner ear defects reminiscent of cochlear hypothyroidism in Slc26a4-related deafness.

Thyroid hormone is essential for inner ear development and is required for auditory system maturation. Human mutations in SLC26A4 lead to a syndromic form of deafness with enlargement of the thyroid gland (Pendred syndrome) and non-syndromic deafness (DFNB4). We describe mice with an Slc26a4 mutation, Slc26a4 (loop/loop) , which are profoundly deaf but show a normal sized thyroid gland, mimicking non-syndromic clinical signs. Histological analysis of the thyroid gland revealed defective morphology, with a majority of atrophic microfollicles, while measurable thyroid hormone in blood serum was within the normal range. Characterization of the inner ear showed a spectrum of morphological and molecular defects consistent with inner ear pathology, as seen in hypothyroidism or disrupted thyroid hormone action. The pathological inner ear hallmarks included thicker tectorial membrane with reduced ß-tectorin protein expression, the absence of BK channel expression of inner hair cells, and reduced inner ear bone calcification. Our study demonstrates that deafness in Slc26a4 (loop/loop) mice correlates with thyroid pathology, postulating that sub-clinical thyroid morphological defects may be present in some DFNB4 individuals with a normal sized thyroid gland. We propose that insufficient availability of thyroid hormone during inner ear development plays an important role in the mechanism underlying deafness as a result of SLC26A4 mutations.

Periorbital Ecchymosis Post Closed Rhinoplasty: Natural History, Risk Factors, and Validation of a New Scoring System.

Postrhinoplasty periorbital ecchymosis is an inevitable side effect contributing to patients' psychological aspect and early postoperative morbidity. Efforts are constantly being made to reduce ecchymosis using different methods with varying success. To evaluate treatment response, it is mandatory to have a reliable score. Several studies suggest other scoring systems, but none has been postrhinoplasty-specific, validated, and accepted. This study aimed to demonstrate the natural history of postrhinoplasty ecchymosis, find potential risk factors for worsening patterns, and suggest a useful and reliable periorbital ecchymosis scoring system for postrhinoplasty follow-up. Methods: This prospective study included 183 patients who underwent closed rhinoplasty by the same surgeon and the same principle method. Photographs of the periorbital ecchymosis were taken on postoperative days 1, 2, and 7. The periorbital area was divided into quarters, and three independent physicians assigned the dominant color of each quarter. Results: There were no significant variations between the three physicians' scoring. The interobserver consistency defined as an excellent scoring system reliability, according to our statistical analysis. The postoperative ecchymosis demonstrated a consistent pattern of spread over time, dominating the medial quarters on early postoperative days 1 and 2, following into the lower lateral quarters in postoperative day 7. We found no correlation between patient demographics and clinical characteristics to ecchymosis patterns and temporal spread. Conclusions: Our study suggests a reliable and easy-to-use postrhinoplasty ecchymosis scoring system. This scoring method can be used for postrhinoplasty ecchymosis assessment and as a research-validated tool to quantify different perioperative treatments to reduce ecchymosis and estimate mid-face trauma.

Humanitarian Outpatient Pediatric Endeavor (HOPE): A Novel Specialist Ambulatory Health-Care Concept in Conflict Areas.

With the collapse of the medical system in Syria, Israel began providing Syrians with humanitarian aid, first to the war-injured and then general medical treatment. We developed a novel specialist ambulatory care concept to provide medical care for Syrian children. Children with their caregivers were transported by bus across the border from Syria to our medical center in Israel for day-stay outpatient-clinic advanced evaluation and treatment due to coordination between Syrian, Red Cross, and Israeli authorities, including Israeli Defense Forces. This retrospective field report includes 371 Syrian children treated as outpatients at Galilee Medical Center between January 2016 and September 2018. In our experience, this novel pediatric ambulatory care concept has been feasible, efficient, and successful in providing specialist care for children in a crisis region devoid of access to health care. We believe it can also serve adult patients and be implemented in other crises and disasters scenarios.

Association between BNT162b2 vaccination and health-related quality of life up to 18 months post-SARS-CoV-2 infection in Israel.

We determined whether COVID-19 vaccination was associated with Quality of Life (QoL) changes among individuals previously infected with SARS-CoV-2 in Israel. Using a validated questionnaire, we collected information about socio-demographics, SARS-CoV-2 infection, COVID-19 vaccination and QoL (using the EQ-5D-5L tool) 3-18 months post-infection among adults tested for SARS-CoV-2 by polymerase chain reaction in Northern Israel between March 2020-June 2022. We compared post-COVID QoL between those vaccinated against COVID-19 at the time of infection and those not, using an adjusted linear regression model, stratified by time elapsed since infection. Of 951 participants, mean EQ-5D Utility Index (EQ-5D UI) was 0.82 (SD = 0.26) and 0.83 (SD = 0.25) among the 227 double and 250 triple vaccinated respectively, compared to 0.76 (SD = 0.33) among those who received 0 dose (n = 243). The size of the effect of vaccination was small (Cohen's d = 0.2). In the adjusted model, previously infected individuals vaccinated with two or more doses reported a QoL score post- infection 0.05 points higher (CI = 0.01-0.10, p = 0.02) compared with those unvaccinated when infected. No association between vaccination and QoL was detected beyond 12 months post-infection. Vaccination with two or more doses of COVID19 vaccine, or at least the BNT162b2 vaccine, may modestly mitigate QoL losses associated with post-acute COVID-19 symptoms, at least in the first 12 months post-infection.

MicroRNAs are essential for development and function of inner ear hair cells in vertebrates.

MicroRNAs (miRNAs) inhibit the translation of target mRNAs and affect, directly or indirectly, the expression of a large portion of the protein-coding genes. This study focuses on miRNAs that are expressed in the mouse cochlea and vestibule, the 2 inner ear compartments. A conditional knock-out mouse for Dicer1 demonstrated that miRNAs are crucial for postnatal survival of functional hair cells of the inner ear. We identified miRNAs that have a role in the vertebrate developing inner ear by combining miRNA transcriptome analysis, spatial and temporal expression patterns, and bioinformatics. Microarrays revealed similar miRNA profiles in newborn-mouse whole cochleae and vestibules, but different temporal and spatial expression patterns of six miRNAs (miR-15a, miR-18a, miR-30b, miR-99a, miR-182, and miR-199a) may reflect their roles. Two of these miRNAs, miR-15a-1 and miR-18a, were also shown to be crucial for zebrafish inner ear development and morphogenesis. To suggest putative target mRNAs whose translation may be inhibited by selected miRNAs, we combined bioinformatics-based predictions and mRNA expression data. Finally, we present indirect evidence that Slc12a2, Cldn12, and Bdnf mRNAs may be targets for miR-15a. Our data support the hypothesis that inner ear tissue differentiation and maintenance are regulated and controlled by conserved sets of cell-specific miRNAs in both mouse and zebrafish.

CLRN1 is nonessential in the mouse retina but is required for cochlear hair cell development.

Mutations in the CLRN1 gene cause Usher syndrome type 3 (USH3), a human disease characterized by progressive blindness and deafness. Clarin 1, the protein product of CLRN1, is a four-transmembrane protein predicted to be associated with ribbon synapses of photoreceptors and cochlear hair cells, and recently demonstrated to be associated with the cytoskeleton. To study Clrn1, we created a Clrn1 knockout (KO) mouse and characterized the histological and functional consequences of Clrn1 deletion in the retina and cochlea. Clrn1 KO mice do not develop a retinal degeneration phenotype, but exhibit progressive loss of sensory hair cells in the cochlea and deterioration of the organ of Corti by 4 months. Hair cell stereocilia in KO animals were longer and disorganized by 4 months, and some Clrn1 KO mice exhibited circling behavior by 5-6 months of age. Clrn1 mRNA expression was localized in the retina using in situ hybridization (ISH), laser capture microdissection (LCM), and RT-PCR. Retinal Clrn1 transcripts were found throughout development and adulthood by RT-PCR, although expression peaked at P7 and declined to undetectable levels in adult retina by ISH. LCM localized Clrn1 transcripts to the retinas inner nuclear layer, and WT levels of retinal Clrn1 expression were observed in photoreceptor-less retinas. Examination of Clrn1 KO mice suggests that CLRN1 is unnecessary in the murine retina but essential for normal cochlear development and function. This may reflect a redundancy in the mouse retina not present in human retina. In contrast to mouse KO models of USH1 and USH2, our data indicate that Clrn1 expression in the retina is restricted to the Müller glia. This is a novel finding, as most retinal degeneration associated proteins are expressed in photoreceptors, not in glia. If CLRN1 expression in humans is comparable to the expression pattern observed in mice, this is the first report of an inner retinal protein that, when mutated, causes retinal degeneration.

Comparisons between lysis and lavage, intra-articular steroid injections, and three-point subsynovial steroid injections using operative single-cannula arthroscopy - A retrospective analysis.

The aim of this study is to compare the effectiveness of intra-articular and three-point sub-synovial steroid injections. In this retrospective Cohort study an OSCA lysis and lavage, intra-articular and threepoint sub-synovial steroid injections were performed and the maximal interincisinal opening (MIO), pain using 10- point visual analog scale (VAS) and quality of life (QOL) were measured one week before the procedure and 1, 3, 6, 12 months, and 2 and 3years after surgery. Sixty-five patients suffering from internal derangement refractory to conservative treatment charts were reviewed. successfully lowered pain (p value = 0.0012), and improved mouth opening (p value = 0.023), and quality of life (QoL) (p value = 0.003) for up to 6 months after surgery. OSCA with intra-articular CS injections effectively lowered pain (p value = 0.0025), and improved mouth opening (p value = 0.03) and QoL (p value = 0.004) for 12 months. In comparison, OSCA with sub-synovial steroid injections was significantly effective in lowering pain (p value = 0.000002), improving mouth opening (p value = 0.000004), and QoL (p value p = 0.000006) for the duration of the 36-month follow-up period within the limitations of the study it seems that the OSCA technique with site-specific, sub-synovial CS injections should be the preferred treatment approach when the priority is long-term success concerning pain relief, increased mouth opening and improved quality of life in Wilkes II-IV patients.

The Modulatory Effect of Adipose-Derived Stem Cells on Endometrial Polyp Fibroblasts.

Endometrial polyps (EPs) are benign overgrowths of the endometrium, with the potential to cause severe complications, ranging from discomfort to inflammation and infertility. Dysfunction of endometrial fibroblasts may be a critical component leading to the development of polyps. Although surgical intervention is the common remedy for severe cases, it comes with drawbacks, including infection, bleeding, and risk of damage to the cervix and adjacent tissues. Adipose-derived mesenchymal stromal cells (ASCs) are at the focus of modern medicine, as key modulators of tissue homeostasis, inflammation, and tissue repair, rendering them prime candidate agents for tissue regeneration and cell-based therapies. In this study, EPs were isolated from patients admitted to the OB/GYN department at the Galilee Medical Center and extracted fibroblasts (endometrial polyp fibroblasts, EPFs) were isolated and characterized. ASCs were isolated from healthy patients. The effect of EPF- and ASC-conditioned media (CM) on polyp-derived fibroblasts was evaluated, in both 2D and 3D assays, as well as on the expression of matrix-related gene expression. Herein, EPFs exposed to ASC-CM exhibited reduced migration, invasion, contraction of hydrogels, and extracellular matrix deposition, compared with those exposed to EPF-CM. Altogether, this study suggests that ASCs may have a modulating effect on fibroblasts involved in forming EPs and may serve as the basis for conservative treatment strategies aimed at treating severe cases of EPs.

COVID-19 knowledge and adherence of dental practitioners to health authority safety guidelines during a pandemic.

OBJECTIVES: This study aimed to assess the degree of dental practitioner adherence to recommendations made during the COVID-19 pandemic. METHOD AND MATERIALS: An online questionnaire was distributed via social media among dental practitioners in Israel who worked during the COVID-19 outbreak. RESULTS: In total, 144 dental practitioners completed the survey; it was found that dental practitioner adherence to all the official PPE use recommendations was 69.8%, whereas 36.8% of dental practitioners reported the use of N95 when needed. Knowledge of self-protection against COVID-19 was rated as "very good" by 37.5% of responders. However, only 25.7% felt "highly protected" by personal protective equipment. Interestingly, many dental practitioners (46.8%) reported adherence to extra protection in addition to the required PPE communicated by the Ministry of Health guidelines. CONCLUSION: Stricter regimens should be applied for dealing with the current challenging pandemic, especially in clinical work with a higher risk for viral transmission. Specific strategies should be followed to ensure good practice to improve dental practitioners' and patients' safety.

Reasons underlying the intention to vaccinate children aged 5-11 against COVID-19: A cross-sectional study of parents in Israel, November 2021.

Vaccination is a key tool to mitigate impacts of the COVID-19 pandemic. In Israel, COVID-19 vaccines became available to adults in December 2020 and to 5-11-year-old children in November 2021. Ahead of the vaccine roll-out in children, we aimed to determine whether surveyed parents intended to vaccinate their children and describe reasons for their intentions. We collected information on parental socio-demographic characteristics, COVID-19 vaccine history, intention to vaccinate their children against COVID-19, and reasons for parental decisions using an anonymous online survey. We identified associations between parental characteristics and plans to vaccinate children using a logistic regression model and described reasons for intentions to vaccinate or not. Parental non-vaccination and having experienced major vaccination side effects were strongly associated with non-intention to vaccinate their children (OR 0.09 and 0.18 respectively, p < .001). Parents who were younger, lived in the socio-economically deprived periphery, and belonged to the Arab population had lower intentions to vaccinate their children. Reasons for non-intention to vaccinate included concerns about vaccine safety and efficacy (53%, 95%CI 50-56) and the belief that COVID-19 is a mild disease (73%, 95%CI 73-79), while a frequent motive for vaccination was the return to normal social and educational life (89%, 95%CI 87-91). Understanding rationales for COVID-19 vaccine rejection or acceptance, as well as parental demographic data, can pave the way for intentional educational campaigns to encourage not only vaccination against COVID-19, but also regular childhood vaccine programming.

Parental intention to vaccinate children aged 5-11 is much lower than vaccine coverage in parental age groupsBeing unvaccinated and having experienced side effects following vaccination were the greatest negative predictors in parents of intention to vaccinate their childrenParents were more likely to accept a COVID-19 vaccine for their children to allow them to return to daily social life and to ensure economic security in the familyParents were more likely to reject a COVID-19 vaccination for health reasons such as safety concerns or due the belief that COVID-19 was a mild disease in children.

Association between BNT162b2 vaccination and reported incidence of post-COVID-19 symptoms: cross-sectional study 2020-21, Israel.

The effectiveness of Coronavirus disease 2019 (COVID-19) vaccines against the long-term COVID-19 symptoms expressed by a substantial proportion of patients is not well understood. We determined whether vaccination with the BNT162b2 mRNA vaccine was associated with incidence of reporting long-term symptoms post-SARS-CoV-2 infection. We invited individuals PCR-tested for SARS-CoV-2 infection at participating hospitals between March 2020 and November 2021 to fill an online questionnaire that included information about demographics, acute COVID-19 episode and symptoms they were currently experiencing. Using binomial regression, we compared vaccinated individuals with those unvaccinated and those uninfected, in terms of post-acute self-reported symptoms. Of the 951 infected, 637(67%) were vaccinated. In the study population, the most prevalent symptoms were: fatigue (22%), headache (20%), weakness of limbs (13%), and persistent muscle pain (10%). After adjusting for age, time from beginning of symptoms to responding to the survey, and baseline symptoms, those who received two vaccine doses were less likely than unvaccinated individuals to report any of these symptoms (fatigue, headache, weakness of limbs, persistent muscle pain) by 62%, 50%, 62%, and 66% respectively, (Risk ratios 0.38, 0.50, 0.38, 0.34, p < 0.04 in the listed sequence). Compared to the 2447 included individuals who never reported SARS-CoV-2 infection, double-vaccinated participants were no more likely to report any of the mentioned symptoms. Vaccination with 2+ doses of BNT162b2 was associated with a reduced risk of reporting most of the common post-acute COVID-19 symptoms. Our results suggest that BNT162b2 vaccination may have a protective effect against longer term COVID-19 symptoms.
