Determining host factors contributing to disease severity in a family cluster of 29 hospitalized SARS‐CoV‐2 patients: Could genetic factors be relevant in the clinical course of COVID‐19?

In this study, we report a large family cluster consisting of 29 genetically related patients hospitalized with coronavirus disease‐2019 (COVID‐19). We sought to determine the clinical characteristics relevant to the clinical course of COVID‐19 by comparing the family cluster to unrelated patients with SARS‐CoV‐2 infection so that the presence of potential determinants of disease severity, other than traditional risk factors previously reported, could be investigated. Twenty‐nine patient files were investigated in group 1 and group 2 was created with 52 consecutive patients with COVID‐19 having age and gender compatibility. The virus was detected for diagnosis. The clinical, laboratory and imaging features of all patients were retrospectively screened. Disease course was assessed using records regarding outcome from patient files retrospectively. Groups were compared with respect to baseline characteristics, disease severity on presentation, and disease course. There was no difference between the two groups in terms of comorbidity and smoking history. In terms of inhospital treatment, use differed not significantly between two groups. We found that all 29 patients in the group 1 had severe pneumonia, 18 patients had severe pneumonia. Hospitalization rates, length of hospital stay, and transferred to intensive care unit were found to be statistically significantly higher in the group 1. In the present study, COVID‐19 cases in the large family cluster were shown to have more severe disease and worse clinical course compared with consecutive patients with COVID‐19 presenting to the same time. We believe further studies into potential genetic mechanisms of host susceptibility to COVID‐19 should include such family clusters.

Evaluation of indirect microparticle activity and parameters of thrombin generation test in healthy infants

Introduction

Circulating microparticles support thrombin generation. The aim of this study is to determine the indirect microparticle activity and the parameters of thrombin generation in healthy infants.

Materials and methods

A total of 85 infants who were brought to follow-up visits were taken into the study. Blood samples were collected. Thrombin generation parameters and indirect microparticle activity were measured.

Results

The infants were divided into four groups according to the time of follow-up visits. Mean ages were 1.18 ± 0.19 months in Group 1, 6.15 ± 0.16 months in Group 2, 12.38 ± 0.46 months in Group 3 and 24.53 ± 0.39 months in Group 4, respectively. There was no statistical difference among the age-based groups with respect to the indirect microparticle activity. The lag time and the TTP levels in Group 1 were lower than that found in Group 2. The ETP and peak levels were higher in Group 1 than that of Group 2. The ETP and peak levels in Group 2 were found lower than those found in older children, but the TTP level was found relatively higher. Statistically correlations were found between indirect microparticle activity and all parameters of thrombin generation.

Conclusions

The absence of a difference in terms of age-based microparticle levels may suggest that the features of microparticles in healthy children of this age group are similar. Age-dependent changes in thrombin generation parameters may suggest a regulation mechanism for the thrombin generation system over the first years of life. The results may provide mean values for indirect microparticle activity and thrombin generation in this healthy group.     

Oral complaints of denture-wearing elderly people living in two nursing homes in istanbul, Turkey

Aim: The aim of this study was to observe and determine oral complaints of people aged 55 years or older, living in two nursing homes in Istanbul, Turkey, and their satisfaction with their complete or partial dentures by means of a simple questionnaire. Methods: Two old peoplea??s homes (one public and one private) in the district of Uskudar in Istanbul agreed to take part in this study. All residents who were available were invited to answer a piloted nine-point questionnaire with questions on age, gender, physical problems, eating, and communication, aesthetic denture wearing and psychological problems. The questions were asked in person by one investigator. The resulting data were entered into SPSS version 15. Results: Out of a total of 210 residents, 130 (61.9%) took part in the study, of whom 53% (n=71) of residents were living in the private nursing home and 60% (n=81) were female. One hundred and five (80%) were denture wearers. More than half of the residents (59%, n=79) were over 75 years old. Problems were mostly seen in older ages, especially those over 75 years old, over 60% of whom reported problems for all the variables listed in the questionnaire. Women were more aware of halitosis than men. Conclusions: The results of this study confirm those of previous studies and suggest that elderly people with dentures, and particularly complete dentures, frequently complain of a wide range of problems including: eating, social interaction and communication and these problems have a detrimental influence on their quality of life.     

An electrophysiologic evaluation of whether open and laparoscopic techniques used in pediatric inguinal hernia repairs affect the genitofemoral nerve

Background

A prospective study was performed to evaluate the effect of inguinal hernia repairs on the genitofemoral nerve (GFN), and to compare postoperative electrophysiologic changes in the GFN of patients who had undergone either open or laparoscopic surgery.

Methods

Seventy patients with a mean age of 6.48 ± 3.49 were enrolled in the study. Either open or laparoscopic techniques were used to operate on the patients' inguinal hernias. In all cases, bilateral GFN motor responses were investigated electrophysiologically using surface electrodes on three occasions: preoperatively, in the first month, and third month postoperatively. t-Tests were used to compare changes in the GFN.

Results

Preoperative mean latency of the GFN in all groups was found to be significantly prolonged on the hernia side, compared with the non-hernia side (P = 0.01). Although no difference was observed in the latency levels of the GFN on the operated side at the preoperative and early postoperative stages, GFN latency levels decreased significantly in the late postoperative period in the laparoscopic group (P < 0.05). In the late postoperative period, amplitudes of GFN motor responses were significantly higher in the laparoscopic group than the open repair group (0.91 ± 0.11 mV and 0.57 ± 0.053 mV, respectively; P < 0.05).

Conclusion

Preoperative prolonged latency of GFN on the hernia side is likely to occur due to the pressure on the nerve caused by the hernia mass. By surgically removing the hernia mass, this buildup of pressure is prevented, decreasing the latency of the GFN. The significantly higher motor response amplitudes and decreased latency in the late postoperative stage for the laparoscopic group may be due to the fact that this technique is less invasive.     

Avaliação de entesopatia em pacientes com fibromialgia por meio do novo índice ultrassonográfico de entesite

ObjectiveThe aim of the present study is to determine the frequency of enthesopathy in fibromyalgia (FM) by using a newly developed ultrasonography (US) method, the Madrid Sonography Enthesitis Index (MASEI).MethodsThis study was conducted on 38 consecutive patients with FM and 48 healthy sex- and age-matched controls. Six entheseal sites (olecranon tuberosity, superior and inferior poles of patella, tibial tuberosity, superior and inferior poles of calcaneus) on both lower limbs were evaluated. All US findings were identified according to MASEI. Scores of patients and controls were compared by Student's t-test and Mann-Whitney U-test. Validity was analysed by receiver operating characteristic curve. Values of P < 0.05 were considered significant.ResultsTotal enthesitis score was 7.39 ± 4.99 (mean ± SD) among FM patients and 3.7 ± 3.22 among healthy controls (P < 0.001). The receiver operating characteristic curve established an ultrasound score of > 3.5 in the FM group as the best cut-off point to differentiate between cases and controls. No statistically significant correlation was found between the MASEI score and the FM disease duration, and the location of the tender points.ConclusionsMisdiagnoses of FM are harmful to patients and the community, and the presence of enthesopathy among FM patients increases. Its detection with the MASEI score may help to discriminate FM patients presenting with ill-defined symptoms and signs, in order to prevent mistreatment.
