Medical doctors' coping strategies with post-earthquake stress and their relationship with presenteeism.

Disasters can lead to decreased functionality in medical practice. This study aimed to quantitatively measure presenteeism and to determine the role of coping strategies among disaster-victim doctors living in a city affected by the 2023-Turkey earthquakes. This cross-sectional study included 220 doctors reached through social media groups using the convenience sampling method. A weak negative relationship was found between presenteeism and positive re-evaluation, one of the coping strategies with earthquake stress. A weak negative correlation was found between the Positive Reappraisal sub-dimension score of the Coping with Earthquake Stress Scale (CESS) and presenteeism (r = -0.299, p < 0.001). In the linear regression analysis, the sub-dimensions that contributed significantly to the model were found to be the Positive Reappraisal sub-dimensions of CESS, whose increase resulted in a decrease in presenteeism and Seeking Social Support sub-dimension, whose increase caused an increase in presenteeism. Presenteeism was higher in those who lost their loved ones, had damage in their workplace/home, and thought they were helpless or in danger. Both material and emotional factors decreased functionality at work after an earthquake. We recommend developing material and psychological support strategies to reduce presenteeism in post-disaster periods.

[Humoral Immune Response in Inactivated SARS-CoV-2 Vaccine: When Should a Booster Dose be Administered?] / Inaktif SARS-CoV-2 Asisi Humoral Immün Yanit: Rapel Doz Ne Zaman Uygulanmalidir?

Vaccination induces the development of long-lasting immunity necessary for a sustained and essential protective antibody response. Understanding how long the humoral immune response induced by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) inactivated vaccine lasts is important to create an effective immunization scheme. This study aimed to detect the first, third, sixth month concentrations and seroconversion rates of the antibodies induced by the inactivated vaccine. The study included 282 healthcare workers who were vaccinated at days 0 and 28 by the inactivated SARS-CoV-2 vaccine (3 µg/0.5ml). Anti-S-RBD-IgG (receptor binding domain) antibody concentrations and seroconversion rates were examined in vaccinated healthcare workers at the first, third and sixth months after the vaccination. MAGLUMI SARS-CoV-2 S-RBD IgG (CLIA) (Snibe Diagnostics, Chinese) kit was used for the detection of antibodies. The mean age of the healthcare workers was 38.93 ± 10.59 (min= 21-max= 64). After the administration of the second vaccine dose, the participants were found to be reactive for anti-SRBD-IgG antibodies by 98.2% and 97.8% at the first and third months, respectively,. The decrease in the mean plasma concentrations of anti-S-RBD IgG was observed as 56.7% in the cohort with only two doses of the vaccine (first month: 42.4 AU/ml versus third month: 18.2 AU/ml). In the cohort with a history of coronavirus disease 2019 (COVID-19) prior to the vaccination, the decrease was observed as 25.1% (first month: 58.29 versus third month: 43.64 AU/ml) and at a mean of 57.4 (0-90) days prior to vaccination, the decrease rate was 43.1% (first month: 55.05 AU/ml versus third month: 31.28 AU/ml), keeping more stable in participants infected at a mean of 183.1 (91-330) days prior to vaccination(a decrease of 5.2%; with 62.34 AU/ml at first and 59.08 AU/ml at third months). At the end of the sixth month, antibodies could not be detected in 16.7% of people who (n= 42) received two doses of the inactivated vaccine, and the amount of anti-S-RDB IgG decreased by an average of 52.5% compared to the third month, and by 74.8% compared to the first month. Antibody concentrations at the first, third, and sixth months after the vaccination with two doses of the inactivated SARS-CoV-2 vaccine were found to be decreased and at the sixth month, the rate of non-reactive people was 16.7%. As participants who had COVID-19 at a mean of 181 (90-330) days before the vaccination presented with a more stable antibody level, it can be concluded that a booster at months 6-12, resulting in a schedule of 0-1-6 months, is recommended for the inactive SARS-CoV-2 vaccination for effective herd immunity.

Protectivity of COVID-19 Vaccines and Its Relationship with Humoral Immune Response and Vaccination Strategy: A One-Year Cohort Study.

This prospective cohort study aimed to evaluate the efficacy of COVID-19 vaccine schemes, homologous versus heterologous vaccine strategies, and vaccine-induced anti-S-RBD-IgG antibody response in preventing COVID-19 among 942 healthcare workers 1 year after vaccination with the inactivated and/or mRNA vaccines. All participants received the first two primary doses of vaccines, 13.6% of them lacked dose 3, 50.5% dose 4, and 90.3% dose 5. Antibody levels increased with the increase in number of vaccine doses and also in heterologous vaccine regimens. In both inactive, mRNA vaccines and mixed vaccination, infection rates were significantly higher in two-dose-receivers, but lower in four- or five-dose receivers and increasing the total number of vaccine doses resulted in more protection against infection: the three-dose regimen yielded 3.67 times more protection, the four-dose 8 times, and five-dose 27.77 times more protection from COVID-19 infection, compared to any two-dose vaccination regimens. Antibody levels at the end of the first year of four- or five-dose-receivers were significantly higher than two- or three-dose receivers. To conclude, an increased number of total vaccine doses and anti-S-RBD antibody levels increased the protection from COVID-19 infection. Therefore, four or more doses are recommended in 1 year for effective protection, especially in risk groups.

Effect of Heterologous Vaccination Strategy on Humoral Response against COVID-19 with CoronaVac plus BNT162b2: A Prospective Cohort Study.

This study aimed to evaluate the mixed and homogeneous application of the inactivated SARS-CoV-2 vaccine CoronaVac (CV) and the mRNA vaccine BNT162b2 (BNT). This prospective cohort study included 235 health care workers who had received two prime shots with CoronaVac. They were divided into three cohorts after the third month: Cohort-I (CV/CV); Cohort-II (CV/CV/CV); and Cohort-III (CV/CV/BNT). Anti-S-RBD-IgG and total anti-spike/anti-nucleocapsid-IgG antibody concentrations were examined in vaccinated health workers at the 1st, 3rd, and 6th months following the second dose of the vaccination. The mean age of 235 health care workers who participated in the project was 39.51 ± 10.39 (min-max: 22-64). At the end of the 6th month, no antibodies were detected in 16.7% of Cohort-I participants, and anti-S-RDB IgG levels showed a decrease of 60% compared to the levels of the 3rd month. The antibody concentrations of the 6th month were found to have increased by an average of 5.13 times compared to the 3rd-month levels in Cohort-II and 20.4 times in Cohort-III. The heterologous vaccination strategy "CoronaVac and BNT162b2 regimen" is able to induce a stronger humoral immune response and it will help remove inequalities in the developing world where CoronaVac was the initial prime.

SARS-COV-2 vaccine: first-month results of a six-month follow-up study.

BACKGROUND: Various COVID-19 vaccines are being developed around the world. Important questions to be answered regarding vaccines are efficacy, safety, and whether antibodies are protective when used in different communities. This study aimed to determine seroconversion rates of the inactivated SARS-CoV-2 vaccine in healthcare workers in a hospital and short-term adverse events due to the vaccine. METHODS: The study carried out in Çukurova University, Turkey, comprised of 282 healthcare workers who received two doses of the inactivated SARS-CoV-2 vaccine administered in two 3 µg doses, 28 days apart. On day 28, after the second dose, antiS-RBD IgG and total anti-spike and anti-nucleocapsid IgM and IgG antibodies against SARS-CoV-2 were detected by using in vitro chemiluminescence immunoassay method. RESULTS: The mean age of participants was 39.06±10.65 (min=21, max=65) with 43.6% males and 56.4% females. On day 28, after the second dose, the seroconversion rates were found to be 92.9% for total anti-spike and anti-nucleocapsid IgG and 15.2% for IgM and 98.2% for anti-S-RBD IgG antibodies and having natural COVID-19 prior to vaccination, age and comorbidity were found to be significant factors for immunogenicity. The incidence of at least one adverse event was found as 29.8% after the first dose and 24.1% after the second dose, with the most common adverse events of having pain at the injection site, weakness, fatigue, and headache.

Occupational health and safety characteristics of agricultural workers in Adana, Turkey: a cross-sectional study.

BACKGROUND: Among agricultural workers, especially in the seasonal migratory ones, housing and hygiene related issues, occupational accidents, low levels of education, poverty and absence of social security problems emerge as significant public health problems. This study aims to compare migrant-seasonal workers (MSWs) and resident agricultural workers (RAWs) in terms of socio-demographic characteristics and occupational health and safety in Adana, one of Turkey's most important agricultural cities. METHODS: This cross-sectional study was conducted on RAWs and MSWs, aged 15-65, operating in the province of Adana. The calculated sample sizes for both MSWs and RAWs were distributed using stratified simple random sampling to five districts of Adana. RESULTS: The mean age of the 798 participating agricultural workers was 34.6 ± 14.2. Of the RAWs, 78.8% and of the MSWs 57.0% were male; 5.8% of RAWs and 32.8% of MSWs were illiterate. The mean number of people in the households of the participating workers was 5.1 for RAWs and 6.6 for MSWs. Of the RAWs, 20.5% were not covered by any social security scheme while this percentage was 35.1% in MSWs. RAWs worked 9.9 h a day while MSWs worked 10.9 h a day. Of the agricultural workers, 12.9% had injuries caused by occupational accidents. DISCUSSION: Agricultural workers, who are a large part of Turkey's economically active population, do not have healthy and safe working conditions. New regulations in the fields of social security, record keeping, monitoring, supervision, education and occupational health have been implemented recently to solve these problems. Despite the recent improvements there are still some problematic issues in the auditing of the necessary practices.

Occupational Risks of Health Professionals in Turkey as an Emerging Economy.

BACKGROUND: Health services are one of the work areas that contain important risks in terms of the occupational health and safety of the laborer. Professionals in various areas of health services encounter biological, chemical, physical, ergonomic, and psychosocial risks, particularly in hospitals. OBJECTIVES: This study has been performed to evaluate the impacts of the occupational risks on health of health professionals in Turkey. FINDINGS: In Turkey, as an emerging economy, the history of studies on health professionals is not longstanding. There have been various regulations intended for the occupational health and safety of health professionals in line with the Regulation of the Provision on Patient and Staff Safety prepared in 2012. However, applications can differ from region to region, institution to institution, and person to person. CONCLUSIONS: We believe that this review will lead health professionals to be aware of occupational risks and contribute to planning health services for health professionals.

The role of domestic tap water on Acanthamoeba keratitis in non-contact lens wearers and validation of laboratory methods.

Acanthamoeba is increasingly recognized as an important cause of keratitis in non-contact lens wearers while contact lens wear is the leading risk factor for Acanthamoeba keratitis (AK). It is unlikely that the Acanthamoeba colonization is a feature which is effective only in patient's homes with infectious keratitis since the organism has been isolated from domestic tap water. Two hundred and thirty-one (231) corneal scrapings were taken from infectious keratitis cases, and four contact lens solutions and domestic tap waters were taken from 22 out of 44 AK-diagnosed patient's homes. Microscopic examination, culture, PCR, real-time PCR and DNA sequencing analyses were used for AK-diagnosed samples. The real-time PCR was the most sensitive (100 %) one among the methods used in diagnosis of AK. The 44 (19.0 %) out of 231 corneal scrapings, 4/4 (100 %) contact lens solution and 11/22 (50 %) of domestic tap water samples were found to be positive by real-time PCR for Acanthamoeba. A. griffini (T3), A. castellanii (T4) and A. jacobsi (T15) genotypes were obtained from corneal scrapings, contact lens solutions and domestic tap water samples taken from the patient's homes diagnosed with AK. The isolation of Acanthamoeba containing 6/22 (27.3 %) A. griffini (T3), 14/22 (63.6 %) A. castellanii (T4) and 2/22 (9.1 %) A. jacobsi (T15) from the domestic tap water outlets of 22 of 44 (50 %) of patient's homes revealed that is a significant source of these organisms. A. griffini (T3) and A. jacobsi (T15) genotypes have not been determined from AK cases in Turkey previously. Thus, we conclude that Acanthamoeba keratitis is associated with exposition of patients who has ocular trauma or ocular surface disease to domestic tap water in endemic or potentially endemic countries.

Epidemiology of tinea pedis and toenail tinea unguium in worshippers in the mosques in Adana, Turkey.

The aim of this study was to determine the prevalence of dermatomycosis and the risk factors in those who perform their prayers in the mosques in the city center of Adana Province. The diagnosis of dermatomycosis was made on the basis of direct microscopy and/or culture in addition to clinical findings. Among 461 subjects, 136 (29.5%) had tinea pedis, 23 (5.0%) had tinea unguium, and 21 (4.5%) had both infections simultaneously, with a resulting total of 180 (39.0%) cases of dermatomycosis. The causative agents by frequency were: Trichophyton rubrum (67.0%), T. mentagrophytes var. interdigitale (31.1%), and Candida albicans (1.9%). The prevalence of the foot dermatomycosis was found to be high among those who practiced ablution 3-5 times a day and did not dry their feet immediately, who used rubber shoes, and/or who shared their shoes. Pedal dermatophyte infection seems to be a major problem among the adult Muslim male population regularly attending mosques especially in 5th and 6th decades of life.
