Assessment of Knowledge and Concern of People Living with HIV Regarding Human Mpox and Vaccination.

INTRODUCTION: Mpox virus is an orthopoxvirus that causes the zoonotic infectious disease known as mpox. The disease can also spread from humans to humans. It can be transmitted through contact with bodily fluids, lesions on the skin, or internal mucosal surfaces. METHOD: The number of mpox cases increased during the COVID-19 pandemic. Early diagnosis and prompt management of mpox are critical in people living with HIV (PLHIV). In this study, a cross-sectional survey was conducted among PLHIV followed at the outpatient clinic between 20 April-20 August 2023. A questionnaire was used to assess the knowledge and anxiety levels of patients as well as their opinions about vaccination against mpox. The severity of symptoms in the past two weeks was assessed using the Generalised Anxiety Disorder 7-item scale. A total of 203 PLHIV were interviewed for this survey study. RESULT: The mean age was 39.37±11.93. The majority of them were male (86.7%), and 41.4% were men who have sex with men (MSM). Only 21 of the surveyed participants (10.4%) had a "good knowledge" score about mpox. The mean knowledge score on human Mpox was 2.05 (min:0-max:8), and 107 (52.7%) had a score of 0. CONCLUSION: The future study should focus on continuous education, promoting awareness through programs and establishing measures to successfully overcome identified variables that contribute to mpox pandemic understanding and attitudes. Applying the lessons learned from the COVID-19 pandemic will help the management of mpox virus.

Malnutrition risk frequency and independent risk factors associated with mortality in hospitalized elderly patients with COVID-19 in Turkey.

BACKGROUND AND OBJECTIVES: Malnutrition is common in elderly patients and is an important geriatric syndrome that increases mortality. We aim to examine the frequency of malnutrition and independent risk factors associated with mortality in hospitalized elderly patients with COVID-19. METHODS AND STUDY DESIGN: Patients aged 65 years and older with COVID-19, who were hospitalized between 15th March and 30th April 2020, were included. Demographic characteristics of the patients, their comorbid diseases, medications, malnutrition, and mortality status were recorded. Nutritional Risk Screening-2002 was used as a malnutrition risk screening tool. The factors affecting mortality were analyzed using multivariate Binary Logistic regression analysis. RESULTS: Of the 451 patients included in the study, the mean age was 74.8±7.46 and 51.2% of them were female. The mean number of comorbid diseases was 1.9±1.28. Malnutrition risk was 64.7%, polymorbidity rate was 57.6% and polypharmacy was 19.3%. Mortality rate was found 18.4%. The risk factors affecting mortality were presented as malnutrition risk (OR: 3.26, p=0.013), high number of comorbid diseases (OR: 1.48, p=0.006), and high neutrophil/lymphocyte ratio (OR: 1.18, p<0.001), C-reactive protein (OR: 1.01, p<0.001), and ferritin (OR: 1.01, p=0.041) in elderly patients with COVID-19. Malnutrition risk (3.3 times), multiple comorbid diseases (1.5 times), and high neutrophil/lymphocyte ratio (1.2 times) were independent risk factors that increased the mortality. CONCLUSIONS: The frequency of malnutrition risk and mortality in elderly patients with COVID-19 is high. The independent risk factors affecting mortality in these patients are the risk of malnutrition, multiple comorbid diseases, and a high neutrophil/lymphocyte ratio.

PENTRAXIN 3 LEVELS CORRELATE WELL WITH DISEASE SEVERITY AT ADMISSION IN COVID-19 PATIENTS.

Pentraxin 3 (PTX3), a long pentraxin, is not only released from dendritic cells and neutrophils but also from epithelial and endothelial cells such as alveolar epithelium. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) initially activates the innate immune system, causing a complex immune response. Clinical and experimental studies suggest that PTX3, a locally and systemically secreted marker, can be used as a predictor of the severity and mortality in respiratory infections. In the current study, serum PTX3 levels in patients hospitalized with COVID-19 were found to be significantly increased at admission and showed significant association with the disease severity.

Association between Acute Pancreatitis and COVID-19: Could Pancreatitis Be the Missing Piece of the Puzzle about Increased Mortality Rates?

BACKGROUND: The COVID-19 pandemic caused by SARS-CoV-2 commenced in Wuhan China in 2019 and soon spread worldwide. SARS-CoV-2 enters the cell by binding to the ACE II receptor and begins viral replication. The effects and clinical findings of SARS-CoV-2 on the liver, kidney, heart, gastrointestinal (GI) system and especially lungs have been widely discussed. However, the effects on the pancreas-another organ that also expresses ACE II-have not been studied. METHODS: This work prospectively evaluated data from 316 patients who were admitted with a diagnosis of COVID-19 pneumonia. The patients were categorized into three according to the severity of pneumonia (mild, severe, critical). Demographic data, rate of pancreatitis, biochemical parameters, and radiological images from each group were analyzed. The patients were divided into two groups and outcomes were compared: COVID-19 patients with acute pancreatitis (Group P) and without acute pancreatitis (Group C). RESULTS: The median age was 54 (18-87), and the median age for patients with acute pancreatitis was 55 (26-84). As an expected finding, we found a positive correlation between advanced age and mortality (p = 0.0003). 12.6% of the patients had acute pancreatitis. While pancreatitis was not seen in patients on mild status, the rate of pancreatitis was 32.5% in critical patients. Hospitalization and mortality rates were higher in patients with COVID-19 accompanied by acute pancreatitis (p = 0.0038 and p < 0.0001, respectively). C-Reactive Protein (CRP) and ferritin were significantly higher in those who had pancreatitis (p < 0.0001). D-Dimer and procalcitonin levels had only a small difference (p = 0.1127 and p = 0.3403, respectively). CONCLUSION: Acute pancreatitis alone is a clinical condition that can lead to mortality and may be one of the reasons for the exaggerated immune response developing in the progression of COVID-19. Our results point out that the presence of pancreatic damage triggered by SARS-CoV-2 can deteriorate the clinical condition of patients and the mortality rate may increase in these patients.

Relação entre os Sinais de Strain do Ventrículo Direito no Eletrocardiograma e Níveis de Biomarcadores Associados à Gravidade da Pneumonia por COVID-19 / Relationship between Right Ventricular Strain Signs in Electrocardiography and Levels of Biomarkers Associated with COVID-19 Pneumonia Severity

Resumo Fundamento A nova doença por coronavírus (COVID-19) pode levar a uma enfermidade grave e causar a morte. Sabe-se que a COVID-19 afeta o sistema cardiovascular. A detecção precoce da progressão para um estágio grave da doença que afeta o sistema cardiovascular pode desempenhar um papel crítico no tratamento da COVID-19. Objetivos Explorar a possível relação entre a pneumonia por COVID-19 e os achados de strain do ventrículo direito no eletrocardiograma (ECG). Métodos Foi realizado um estudo retrospectivo de 141 pacientes hospitalizados com COVID-19. A correlação de Spearman e as análises de regressão logística foram aplicadas para avaliar as relações entre as manifestações de strain ventricular direito na ECG e os níveis de biomarcadores e outros achados laboratoriais e de imagem do tórax. O nível de significância foi considerado estabelecido como p < 0,05. Resultados Os sinais de ECG de estresse ventricular direito foram significativamente mais frequentes e os níveis de fibrinogênio, PCR e ferritina foram significativamente mais elevados em pacientes com COVID-19 com níveis elevados de hs-cTnI, procalcitonina e dímero-D. A análise univariada mostrou que existem relações significativas entre a presença de pneumonia bilateral, a maioria dos sinais eletrocardiográficos de strain ventricular direito e lesão cardíaca e biomarcadores inflamatórios e trombóticos. A análise multivariada revelou que o supradesnivelamento do segmento ST em V1 e padrão S1Q3T3 são preditores independentes de lesão cardíaca ( odds ratio =0,23; IC95%, 0,06 a 0,90; p=0,035) e níveis elevados de procalcitonina ( odds ratio =0,19; IC 95%, 0,06 a 0,62; p=0,006), respectivamente. Conclusão Os achados do presente estudo sugerem que a dano cardíaco direito é prevalente na COVID-19. Além disso, nosso estudo demonstra o valor clínico do ECG na avaliação e monitoramento de pacientes com pneumonia por COVID-19.

Abstract Background The novel coronavirus disease (COVID-19) may lead to severe disease that can cause death. COVID-19 is known to affect the cardiovascular system. Early detection of the progression to the severe disease stage that affects the cardiovascular system may play a critical role in the treatment of COVID-19. Objectives To explore the possible relationship between the COVID-19 pneumonia and right ventricular strain findings on electrocardiography (ECG). Methods We conducted a retrospective study of 141 hospitalized patients with COVID-19. Spearman's correlation and logistic regression analyses were applied to assess relationships between ECG manifestations of right ventricular strain and levels of biomarkers and other laboratory and chest imaging findings. The significance level was considered as < 0.05. Results The ECG signs of right ventricular stress were significantly more frequent and the levels of fibrinogen, CRP, and ferritin were significantly higher in COVID-19 patients with elevated levels of hs-cTnI, procalcitonin and D-dimer. The univariate analysis showed there are significant relations between the presence of bilateral pneumonia, most of the ECG signs of right ventricular strain and cardiac injury and inflammatory and thrombotic biomarkers. The multivariate analysis revealed that ST-segment elevation in V1and the S1Q3T3pattern are independent predictors of cardiac damage (odds ratio=0.23; 95% CI, 0.06 to 0.90; p=0.035) and elevated procalcitonin levels (odds ratio=0.19; 95% CI, 0.06 to 0.62; p=0.006), respectively. Conclusion The findings of the present study suggest that right heart damage is prevalent in COVID-19. In addition, our study shows the clinical value of ECG in evaluating and monitoring the patients with COVID-19 pneumonia.

Annual influenza vaccination effect on the susceptibility to COVID-19 infection.

OBJECTIVES: We aimed to study the effect of seasonal influenza (flu) vaccination on the susceptibility to coronavirus disease 2019 (COVID-19). METHODS: A total of 203 healthcare workers of a pandemic centre of Istanbul, Turkey, were included in this retrospective study. According to the presence or absence of flu vaccination, participants were divided into group 1 and group 2. A comparison of the rate of COVID-19 was done between these two groups. Also, the mean age and the sex ratio of females/males were evaluated and compared between these two groups. RESULTS: Group 1 participants (n = 65) were older than participants in group 2 (n = 138) (p < 0.05). Despite of this, interestingly, the COVID-19 infection rate was lower in the 1st group (in comparison to the 2nd group) (p < 0.05). CONCLUSION: Our study results showed that, even if low, the flu vaccination may have a protective effect on the susceptibility to COVID-19 infection. Using this beneficial adjuvant effect of the vaccine may help us in this unpredictable battle with the COVID-19 pandemic. Further studies are needed to confirm this assumption.

The mortality rate of COVID-19 was high in cancer patients: a retrospective single-center study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has quickly turned into a global pandemic with close to 5 million cases and more than 320,000 deaths. Cancer patients constitute a group that is expected to be at risk and poor prognosis in COVID pandemic. We aimed to investigate how cancer patients are affected by COVID-19 infection, its clinical course and the factors affecting mortality. METHODS: In our single-center retrospective study, we included cancer patients with laboratory confirmed COVID-19 in our hospital. Demographic, clinical, treatment, and laboratory data were obtained from electronic medical records. Logistic regression methods were used to investigate risk factors associated with in-hospital death. RESULTS: In the hospital, 4489 patients were hospitalized with COVID infection and 77 were cancer patients. The mean age of cancer patients was 61.9 ± 10.9 and 44 of them were male (62%). While the mortality rate in non-cancer patients was 1.51% (n = 68), this rate was significantly higher in cancer patients, 23.9% (n = 17). The stage of the disease, receiving chemotherapy in the last 30 days also lymphopenia, elevated troponin I, D-dimer, CRP, and CT findings were associated with severe disease and mortality. Severe lung involvement (OR = 22.9, p = 0.01) and lymphopenia (OR = 0.99, p = 0.04) are the most important factors influencing survival in logistic regression. CONCLUSIONS: The disease is more severe in cancer patients and mortality is significantly higher than non-cancer patients. These data show that it may be beneficial to develop dynamic prevention, early diagnosis and treatment strategies for this vulnerable group of patients who are affected by the infection so much.

The clinical findings and outcomes of symptomatic pregnant women diagnosed with or suspected of having coronavirus disease 2019 in a tertiary pandemic hospital in Istanbul, Turkey.

AIM: To observe the clinical course of symptomatic pregnant women diagnosed with or suspected of having COVID-19. METHODS: This study analyzed the clinical and laboratory results of 27 patients with real-time polymerase chain reaction (RT-PCR)-confirmed COVID-19 and 25 patients with a suspected COVID-19 diagnosis based on their symptoms and chest computed tomography (CT) findings. The patients' coagulation parameters and acute-phase reactants were evaluated both before and after treatment. The maternal and neonatal outcomes were also reviewed. RESULTS: The mean duration of hospitalization was 6.1 ± 3 days. The gestational age of the patients ranged from 6w2d to 40w2d. Thirty-five patients' CT scan findings suggested viral pneumonia. Four patients delivered vaginally, and 10 patients underwent a cesarean section during the study period. Four of the cesarean deliveries were indicated due to COVID-19 hypoxemia-related fetal distress. Four patients were admitted to the intensive care unit (ICU) after the cesarean section. CONCLUSION: Early hospitalization and medical treatment can alleviate symptoms, improve the clinical course and reduce the need for ICU in symptomatic pregnant patients with suspected or confirmed COVID-19. Chest CT scans are a suitable option for suspected but unconfirmed COVID-19 infection.

Taste and Smell Impairment in COVID-19: An AAO-HNS Anosmia Reporting Tool-Based Comparative Study.

OBJECTIVE: To identify the taste and smell impairment in coronavirus disease 2019 (COVID-19)-positive subjects and compare the findings with COVID-19-negative subjects using the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) Anosmia Reporting Tool. SETTING: Tertiary referral center/COVID-19 pandemic hospital. STUDY DESIGN: Comparative study. SUBJECTS AND METHODS: After power analysis, 128 subjects were divided into 2 groups according to real-time polymerase chain reaction (RT-PCR) COVID-19 testing results. Subjects were called via telephone, and the AAO-HNS Anosmia Reporting Tool was used to collect responses. RESULTS: The mean age of the study group was 38.63 ± 10.08 years. At the time of sampling, rhinorrhea was significantly high in the COVID-19-negative group, whereas those complaints described as "other" were significantly high in the COVID-19-positive group. There was a significant difference in the smell/taste impairment rates of the groups (n = 46% [71.9%] for the COVID-19-positive group vs n = 17 [26.6%] for the COVID-19-negative group, P = .001). For subjects with a smell impairment, anosmia rates did not differ between the groups. The rates of hyposmia and parosmia were significantly high in the COVID-19-positive group. For the subjects with taste impairment, ageusia rates did not differ between groups. The rate of hypogeusia and dysgeusia was significantly high in the COVID-19-positive group. Logistic regression analysis indicates that smell/taste impairment in COVID-19-positive subjects increases the odds ratio by 6.956 (95% CI, 3.16-15.29) times. CONCLUSION: COVID-19-positive subjects are strongly associated with smell/taste impairment.

Influence of multidrug resistant organisms on the outcome of diabetic foot infection.

OBJECTIVES: We described the clinical outcomes of the diabetic patients who had foot infections with multidrug resistant organisms. METHODS: We included the patients with diabetic foot infections (DFI) from 19 centers, between May 2011 and December 2015. Infection was defined according to IDSA DFI guidelines. Patients with severe infection, complicated moderate infection were hospitalized. The patients were followed-up for 6 months after discharge. RESULTS: In total, 791 patients with DFI were included, 531(67%) were male, median age was 62 (19-90). Severe infection was diagnosed in 85 (11%) patients. Osteomyelitis was diagnosed in 291(36.8%) patients. 536 microorganisms were isolated, the most common microorganisms were S. aureus (20%), P. aeruginosa (19%) and E. coli (12%). Methicillin resistance (MR) rate among Staphylococcus aureus isolates was 31%. Multidrug resistant bacteria were detected in 21% of P. aeruginosa isolates. ESBL (+) Gram negative bacteria (GNB) was detected in 38% of E. coli and Klebsiella isolates. Sixty three patients (8%) were re-hospitalized. Of the 791 patiens, 127 (16%) had major amputation, and 24 (3%) patients died. In multivariate analysis, significant predictors for fatality were; dialysis (OR: 8.3, CI: 1.82-38.15, p=0.006), isolation of Klebsiella spp. (OR:7.7, CI: 1.24-47.96, p=0.028), and chronic heart failure (OR: 3, CI: 1.01-9.04, p=0.05). MR Staphylococcus was detected in 21% of the rehospitalized patients, as the most common microorganism (p<0.001). CONCLUSION: Among rehospitalized patients, methicillin resistant Staphylococcus infections was detected as the most common agent, and Klebsiella spp. infections were found to be significantly associated with fatality.

Causative pathogens and antibiotic resistance in diabetic foot infections: A prospective multi-center study.

AIM: Clinical practice guidelines for the management of diabetic foot infections developed by the Infectious Diseases Society of America (IDSA) are commonly used worldwide. The issue of whether or not these guidelines need to be adjusted for local circumstances, however, has seldom been assessed in large prospective trials. METHODS: The Turk-DAY trial was a prospective, multi-center study in which infectious disease specialists from centers across Turkey were invited to participate (NCT02026830). RESULTS: A total of 35 centers throughout Turkey enrolled patients in the trial. Overall, investigators collected a total of 522 specimens from infected diabetic foot wounds for culture from 447 individual patients. Among all isolates, 36.4% were gram-positive organisms, with Staphylococcus aureus the most common among these (11.4%). Gram-negative organisms constituted 60.2% of all the isolates, and the most commonly isolated gram-negative was Escherichia coli (15%). The sensitivity rates of the isolated species were remarkably low for several antimicrobials used in the mild infection group. CONCLUSIONS: Based on our findings, several of the antimicrobials frequently used for empirical treatment, including some also recommended in the IDSA guidelines, would not be optimal for treating diabetic foot infections in Turkey. Although the IDSA guideline recommendations may be helpful to guide empiric antimicrobial therapy of DFIs, they should be adjusted to local conditions.

Characteristics of leptospirosis with systemic inflammatory response syndrome: a multicenter study.

BACKGROUND: Leptospirosis is a common zoonotic infection in the world. In patients with leptospirosis, in case of presence of Systemic Inflammatory Response Syndrome (SIRS), clinical and laboratory findings can be mistaken for sepsis due to other causes of infection. The purpose of this study is to assess the clinical and laboratory parameters of patients with leptospirosis in terms of the presence of SIRS and to examine the association of these with mortality. METHODS: One hundred fifty-seven patients were included in the study. The patients were classified according to the presence or absence of SIRS and divided into SIRS (+) and SIRS (-). Patient files were retrospectively evaluated. Clinical features and laboratory data were compared, and risk factors associated with mortality were determined. RESULTS: SIRS (+) was found in 70 % (n = 110) of patients who had signs on admission. Comparison of the clinical symptoms and findings of organ systems in the SIRS (+) and SIRS (-) showed that abdominal pain and vomiting were significantly more common in the SIRS (+) than in the SIRS (-) (p = 0.025 and p = 0.046, respectively). BUN and serum creatinine levels were significantly higher in the SIRS (+) than in the SIRS (-) (p = 0.002 and p < 0.001, respectively). In follow-up posterior-anterior chest radiography, pathological findings improved in 58.8 % (n = 40) of patients in the SIRS (+) and 27.3 % (n = 9) of patients in the SIRS (-) (p = 0.003). The mortality rate of the SIRS (+) and SIRS (-) was not significantly different (p = 0.868). CONCLUSION: In patients with positive SIRS findings, while examining the etiology of sepsis, leptospirosis should come to mind especially in endemic areas for differential diagnosis. Early initiation of antibiotic and supportive therapy can be lifesaving in these patients.

Tuberculous meningitis in adults: a review of 160 cases.

OBJECTIVE: This study aimed to evaluate epidemiological, clinical, laboratory, and neuroimaging features of 160 adult patients with tuberculous meningitis (TBM) according to "Thwaites' diagnostic index." METHODS: The subjects of this retrospective study are the patients with TBM who were followed up between years 1998 and 2009 in a tertiary referral hospital. Diagnosis of TBM was based on clinical, laboratory, and neuroimaging signs and Thwaites' diagnostic index. RESULTS: Mycobacterium tuberculosis was isolated from CSF in 59 of 148 patients. Seventeen percent of the patients died, 71% recovered completely, and 13% recovered with neurological sequel at the end of the sixth month. CONCLUSIONS: Despite new developments in laboratory or neuroimaging techniques, the diagnosis of TBM is still based on clinical features with the help of laboratory. Early diagnosis by suspecting TBM may prevent therapy delay and may result in decrease in the mortality and morbidity.

Tricuspid Endocarditis and Septic Pulmonary Embolism in an Intravenous Drug User with advanced HIV Infection.

Cardiac complications are becoming increasingly important in patients with HIV infection. Right-sided endocarditis are more common in intravenous drug users (IVDU) with HIV infection. Some studies have pointed out that the clinical outcome of such patients depends on the affected valve referred to the responsible agent rather than the HIV serostatus. However, severe immunosupression and low CD(4) count are associated with increased risk of death. This report presents a case of isolated tricuspid valve endocarditis with advanced HIV infection who was also an IVDU.

Tuberculous meningoencephalitis with severe neurological sequel in an immigrant child.

Central nervous system tuberculosis (TB) is the most devastating manifestation of TB. It is a challenge for clinicians because of the difficulty in making an early diagnosis and the severe consequences of delayed treatment. The aim of this report is to point out the relation between migration and TB based on a 14-year-old child with tuberculous meningoencephalitis (TBM) of an immigrant family. Migration, crowded living conditions and positive family history contribute to the severe course of TB as TBM and miliary TB forms. TB control may prevent these severe manifestations of the disease among immigrants. Prompt diagnosis with helpful early diagnostic tools like polymerase chain reaction in TBM is crucial due to the high mortality and morbidity.

Evaluation of cases admitted to a center in Istanbul, Turkey in 2003 for rabies vaccination and three rabies cases followed up in the last 15 years.

We evaluated the cases of 7,266 individuals who applied to our hospital's Center for Rabies Vaccination between January and December 2003. Among 1,831 female and 5,435 male cases, 37% were given 3 doses of vaccination, 14% were given 5 doses, and in 24% of cases a 2-1-1 vaccination schedule was applied. Antirabies serum of horse origin was given in 179 cases. Regarding the wounds, 83% were superficial and 17% were deep. Most of the cases involved dog bites (74%). Of the dogs involved, 30% were pets (with owners). Only a few (6%) of those pets had been vaccinated. Of the 2 dogs investigated for rabies in Pendik Veterinarian Research Institute, none were found to harbor the disease. In the last 15 years, 3 cases were followed up with a diagnosis of human rabies in our clinic. Domestic animals (without owners, living a somewhat wild life in cities) are still the cause of many rabies cases. As rabies carries a very high fatality risk, public health precautions and education are important as well as post-exposure prophylaxis.
