Post-COVID-19 syndrome in a cohort of hospitalized COVID-19 patients.

OBJECTIVE: The study aimed to investigate the frequency of post-COVID-19 syndrome and associated factors in patients who visited the post-COVID-19 outpatient clinic after hospital discharge in the first, third, and sixth months of the first year of the pandemic. PATIENTS AND METHODS: The study was a clinical cohort study of patients hospitalized due to COVID-19. The modified British Medical Research Council (mMRC) Dyspnea Scale, the Clinical Frailty Scale (CFS), the Mini Nutritional Assessment short-form (MNA-SF), and the Malnutrition Universal Screening Tool (MUST) were evaluated using a standard form and symptom interview by a specialist physician. RESULTS: Of the 254 patients in the study group, 50.4% were women, and their ages ranged from 18 to 85 years, with a mean (SD) of 55.3±11.5. Post-COVID-19 syndrome was diagnosed in 57.5% of the patients. It was found that the frequency of some of the symptoms persisted and increased in the first month, decreased significantly in the third month, and did not differ between the third and sixth months. Body mass index (BMI), MNA-SF, MUST, and CFS improved over time. Multiple logistic regression analysis showed that the risk of the post-COVID-19 syndrome was 1.91- and 1.40-fold higher in patients with severe COVID-19 and patients with more symptoms in the first month, respectively. CONCLUSIONS: COVID-19 is not a short-term infectious disease but an infectious disease with long-term effects. Cohorts of patients who are still symptomatic at the end of the first month after severe COVID-19 should be followed up for a longer period and their clinical outcomes monitored.

Effectiveness of cold application and lavender oil on pain during drain removal: A randomized clinical trial.

Background and Aim: Analgesics are frequently used to prevent acute pain while removing the drain. Additional non-pharmacological methods have come to the agenda as a result of the fact that the pain cannot be fully controlled, and the pharmacological treatment response is variable. Our research was intended to determine the effectiveness of lavender aromatherapy and cold application in controlling pain during drain removal procedure. Materials and Methods: The sample of the prospective randomized controlled study consisted of 121 patients. Patient data were collected using the introductory information form and the numerical pain scale. Four groups of patients were formed (lavender oil, oxygen, cold application, control), respectively. In all groups, vital signs and pain levels were evaluated before the drain removal procedure, as soon as and 15 minutes after it was withdrawn. Results: Within the limits of study, lavender aromatherapy and cold application to the drainage area were found to be effective in reducing pain during drainage. When the effect on vital signs was evaluated, it was found that the pre-procedure systolic blood pressure was higher in both the lavender group and the cold application group than the post-procedure systolic blood pressure, and the respiratory rate was higher in the control group during the procedure. Conclusions: According to the study, it was found that applying lavender and cold application to the patients before the drainage procedure was effective in controlling pain.

Long-term sustainability of zero central-line associated bloodstream infections is possible with high compliance with care bundle elements.

Central-line-associated bloodstream infection (CLABSI) is one of the most important problems in intensive care units (ICUs) worldwide. A bundle of CLABSI care measures was introduced at a 13-bed medical/surgical ICU in Kocaeli, Turkey in January 2010. Compliance rates with the bundle were measured at the beginning of the third quarter of 2010 until June 2013 and compared with CLABSI rates. During the post-intervention period, of 2196 ICU patients, 732 lines placed for 4366 line-days were monitored. Feedback to staff reinforced a culture of patient safety in the ICU. Infection rates remained zero for 38 months after the implementation. There was a strong negative correlation between bundle compliance rate and CLABSI rates. With the implementation of the central-line bundle of care, together with emphasis on high compliance with all its components and a culture of patient safety, it was possible to achieve and maintain a zero rate of CLABSI in this ICU.

Les infections sur cathéter central sont l'un des problèmes les plus importants dans les unités de soins intensifs au niveau mondial. Un ensemble de soins dispensés en cas d'infections sur cathéter central a été introduit dans une unité de soins intensifs médicaux et chirurgicaux de 13 lits à Kocaeli (Turquie) en janvier 2010. Le degré d'application de l'ensemble de soins a été évalué du début du troisième trimestre 2010 jusqu'à juin 2013 et comparé aux taux d'infections sur cathéter central. Au cours de la période suivant l'intervention, parmi les 2196 patients ayant séjourné dans l'Unité des soins intensifs, 732 cathéters centraux posés pendant 4366 jours cumulés ont été soumis à observation. Le retour d'information fourni au personnel a permis de renforcer la culture de la sécurité du patient en unité de soins intensifs.Les taux d'infections sont restés nuls pendant les 38 mois ayant suivi la mise en oeuvre. Il existait une forte corrélation négative entre le degré d'application de l'ensemble de soins et les taux d'infections sur cathéter central. La mise en oeuvrede cet ensemble de soins concernant les cathéters centraux, associée à l’accent mis sur le degré d'application de toutes ses composantes et une culture de la sécurité du patient, a permis d'atteindre et de maintenir un taux zéro d'infection sur cathéter central dans cette unité de soins intensifs.

Region growing by sector analysis for detection of blue-gray ovoids in basal cell carcinoma.

Blue-gray ovoids (B-GOs) are critical dermoscopic structures in basal cell carcinomas (BCCs) that pose a challenge for automatic detection. Due to variation in size and color, B-GOs can be easily mistaken for similar structures in benign lesions. Analysis of these structures could help further accomplish the goal of automatic BCC detection. This study introduces an efficient sector-based method for segmenting B-GOs. Four modifications of conventional region-growing techniques are presented: (i) employing a seed area rather than a seed point, (ii) utilizing fixed control limits determined from the seed area to eliminate re-calculations of previously-added regions, (iii) determining region growing criteria using logistic regression, and (iv) area analysis and expansion by sectors. Contact dermoscopy images of 68 confirmed BCCs having B-GOs were obtained. A total of 24 color features were analyzed for all B-GO seed areas. Logistic regression analysis determined blue chromaticity, followed by red variance, were the best features for discriminating B-GO edges from surrounding areas. Segmentation of malignant structures obtained an average Pratt's figure of merit of 0.397. The techniques presented here provide a non-recursive, sector-based, region-growing method applicable to any colored structure appearing in digital images. Further research using these techniques could lead to automatic detection of B-GOs in BCCs.

Bullous skin reaction seen after extravasation of calcium gluconate.

Intravenous (IV) calcium is usually given to temporarily treat the effects of hyperkalaemia on muscle and heart. When extravasation of a calcium gluconate infusion occurs, there may be rapid and marked swelling and erythema, with signs of soft-tissue necrosis or infection, and ensuing extensive local calcification, called calcinosis cutis. We report a 26-year-old woman who was hospitalized for exacerbation of acute intermittent porphyria. She had a history of hypertension and chronic renal failure. On the second day of her hospitalization, she developed hyperpotassaemia (6.7 mEq/L potassium; normal range 3.5-5 mEq/L). She was given an IV infusion of 10 mL calcium gluconate into the left dorsal pedal vein. Bullous skin reactions occurred in the infusion area nearly 2 h after administration. The patient's leg was elevated and the lesions cleaned with 0.9% saline. By day 9 of hospitalization, the lesions had markedly regressed. Several drugs have been associated with dermoepidermal blistering as an adverse drug reaction, but there is only one existing report in the literature about this side-effect associated with calcium gluconate. Clinicians should be alert to the possibility of bullous skin reactions, which may be a predictor of extravasation and necrosis, when treating patients with IV calcium gluconate.

Variations in serum cholinesterase activity in different age and sex groups.

Measurements of serum cholinesterase activity has been used to assess liver function, predict susceptibility to prolonged apnoea after administration of the muscle relaxant succinylcholine and monitor excessive exposure to the anti-cholinesterase organophosphorus insecticides (1, 2). Serum cholinesterase activity can be affected by many physiological and pathological conditions such as age, pregnancy, puerperium, obesity, some drug therapy, and liver diseases. Additionally, congenital cholinesterase deficiency, which is due to several genetic variants of the enzyme, has also been reported (3, 4). Since the enzyme activity is altered by many factors, we aimed to show the distribution of serum cholinesterase activity levels in different age and sex groups, in order to establish the reference limits in our population.
