CARDIORENAL SYNDROME AND COVID-19.

The purpose of this paper is to analyses the cases with cardiorenal syndrome, and the ratio of cardiovascular disease and COVID-19. Prospective methods were used to conduct this research, including the period (January 2020-December 2021). Cases of patients treated at the Nephrology Clinic at the University Clinical Center of Kosovo (UCCK) have been studied. The categorical variables were analyzed with the X² test and the Fisher exact test. The study included 120 patients with acute renal disease treated at the Nephrology Clinic at the University Clinical Center of Kosovo (UCCK), of which 46 (38.3%) female and 74 (61.6%) male. Of the 120 patients included in the study 4 were 18-34 years old, 8 were 35-49 years old, 30 were 50-64 years old, and 78 were > 65 years old. There is a strong link between cardiorenal syndrome and age. Regarding cardiorenal syndrome and its association with other diseases in this prospective study were found these concomitant diseases such as: diabetes mellitus type 2, secondary anemia, hypothyroidism, hyperparathyroidism, pneumonia, sepsis, ascites, mesenteric tumor, hyperkalemia, and Covid-19 Infection. There is a strong link between cardiorenal syndrome and COVID-19 Infection. In recent decades various studies have been done against the definition of cardiorenal syndrome, the understanding of pathophysiology, the use of new biomarkers that represent a new dimension in the diagnostic algorithm, and the difficulties in treating this syndrome.

[Area of the foveal avascular zone in patients with refractive errors]. / Ploshchad' foveal'noi avaskulyarnoi zony pri anomaliyakh refraktsii.

PURPOSE: To investigate the dependence of the area of the foveal avascular zone (FAZ) on axial eye length (AL) and to develop a feasible method for correcting this dependence. MATERIAL AND METHODS: The study involved 209 patients over the age of 18 years (209 eyes), of them 52 patients with AL of 20-22 mm (hyperopia group), 60 patients with AL of 25.5-28.5 mm (myopia group) and 97 patients with AL of 22.5-24.5 mm (emmetropia group). Optical coherence tomography angiography (OCTA) examination was performed on Cirrus HD-OCT 5000 with AngioPlex («Carl Zeiss Meditec¼, Germany). RESULTS: FAZ area was corrected using the Littmann-Bennett formula modified by A.A. Shpak and M.V. Korobkova. FAZ area values both in emmetropic patients and in patients with refractive errors varied over a very wide range. Before correction, AL had a significant influence on the FAZ area (mm2), which compared to the emmetropia group (0.27±0.09) was significantly reduced in the myopia group (0.21±0.07; p<0.000) and increased in the hyperopia group (0.31±0.11; p=0.015). The corrected FAZ area values did not differ in the compared groups. After correction the FAZ area decreased on average by 19% in the hyperopia group and increased by 25% in the myopia group. A chart and an Excel (Microsoft)/LibreOffice Calc program have been developed for correction of the FAZ area depending on the AL. CONCLUSION: Refractive errors, especially high-degree ones, have a significant effect on the FAZ area. This study proposes an original chart and a calculation program for correct interpretation of FAZ area measurements in patients with refractive errors, providing an accessible and quick way to assess the obtained results.

Group problem management plus (PM+) to decrease psychological distress among Syrian refugees in Turkey: a pilot randomised controlled trial.

BACKGROUND: Syrian refugees resettled in Turkey show a high prevalence of symptoms of mental disorders. Problem Management Plus (PM+) is an effective psychological intervention delivered by non-specialist health care providers which has shown to decrease psychological distress among people exposed to adversity. In this single-blind pilot randomised controlled trial, we examined the methodological trial procedures of Group PM+ (gPM+) among Syrian refugees with psychological distress in Istanbul, Turkey, and assessed feasibility, acceptability, perceived impact and the potential cost-effectiveness of the intervention. METHODS: Refugees with psychological distress (Kessler Psychological Distress Scale, K10 > 15) and impaired psychosocial functioning (World Health Organization Disability Assessment Schedule, WHODAS 2.0 > 16) were recruited from the community and randomised to either gPM+ and enhanced care as usual (E-CAU) (n = 24) or E-CAU only (n = 22). gPM+ comprised of five weekly group sessions with eight to ten participants per group. Acceptability and feasibility of the intervention were assessed through semi-structured interviews. The primary outcome at 3-month follow-up was symptoms of depression and anxiety (Hopkins Symptoms Checklist-25). Psychosocial functioning (WHODAS 2.0), symptoms of posttraumatic stress disorder and self-identified problems (Psychological Outcomes Profiles, PSYCHLOPS) were included as secondary outcomes. A modified version of the Client Service Receipt Inventory was used to document changes in the costs of health service utilisation as well as productivity losses. RESULTS: There were no barriers experienced in recruiting study participants and in randomising them into the respective study arms. Retention in gPM+ was high (75%). Qualitative analyses of the interviews with the participants showed that Syrian refugees had a positive view on the content, implementation and format of gPM+. No adverse events were reported during the implementation. The study was not powered to detect an effect. No significant difference between gPM+ and E-CAU group on primary and secondary outcome measures, or in economic impacts were found. CONCLUSIONS: gPM+ delivered by non-specialist peer providers seemed to be an acceptable, feasible and safe intervention for Syrian refugees in Turkey with elevated levels of psychological distress. This pilot RCT sets the stage for a fully powered RCT. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT03567083 ; date: 25/06/2018.

Child maltreatment and NR3C1 exon 1F methylation, link with deregulated hypothalamus-pituitary-adrenal axis and psychopathology: A systematic review.

BACKGROUND: Epigenetics offers one promising method for assessing the psychobiological response to stressful experiences during childhood. In particular, deoxyribonucleic acid (DNA) methylation has been associated with an altered hypothalamus-pituitary-adrenal (HPA) axis and the onset of mental disorders. Equally, there are promising leads regarding the association between the methylation of the glucocorticoid receptor gene (NR3C1-1F) and child maltreatment and its link with HPA axis and psychopathology. OBJECTIVE: The current study aimed to assess the evidence of a link among child maltreatment, NR3C1-1F methylation, HPA axis deregulation, and symptoms of psychopathology. METHODS: We followed the Prisma guidelines and identified 11 articles that met our inclusion criteria. RESULTS: We found that eight studies (72.72%) reported increased NR3C1-1F methylation associated with child maltreatment, specifically physical abuse, emotional abuse, sexual abuse, neglect, and exposure to intimate partner violence, while three studies (27.27%) found no significant association. Furthermore, a minority of studies (36.36%) provided additional measures of symptoms of psychopathology or cortisol in order to examine the link among NR3C1-1F methylation, HPA axis deregulation, and psychopathology in a situation of child maltreatment. These results suggest that NR3C1-1F hypermethylation is positively associated with higher HPA axis activity, i.e. increased production of cortisol, as well as symptoms of psychopathology, including emotional lability-negativity, externalizing behavior symptoms, and depressive symptoms. CONCLUSION: NR3C1-1F methylation could be one mechanism that links altered HPA axis activity with the development of psychopathology.

[Femtosecond laser-assisted cataract surgery]. / Tekhnologicheskoe osnashchenie khirurgii katarakty femtolazernym soprovozhdeniem.

Femtosecond laser-assisted cataract surgery (FLACS) is a new chapter in the history of cataract surgery. The use of femtosecond laser allows automation of the main stages of operation such as capsulotomy, lens fragmentation and creation of corneal incisions; it improves predictability and safety of the procedure and improves refractive outcomes. This article analyzes advantages and disadvantages of the new technology based on literature data and authors' own experience.

Enhancement of exposure therapy in participants with specific phobia: A randomized controlled trial comparing yohimbine, propranolol and placebo.

BACKGROUND: Recent research indicates that pharmacological agents may enhance psychotherapeutic outcome. Yet, empirical results have not been conclusive with respect to two pharmacological agents, yohimbine hydrochloride (YOH) and propranolol. YOH is suggested to enhance emotional memory by elevating norepinephrine, whereas the ß-adrenergic receptor antagonist propranolol might help better cope with feared situations by reducing accompanying bodily sensations. METHODS: In this controlled trial, fifty-six participants with specific phobia were randomly assigned to either 1) virtual reality exposure therapy (VRET) plus YOH, 2) VRET plus Propranolol, or 3) VRET plus placebo. Participants in all conditions received three sessions of VRET over a period of two weeks. RESULTS: We conducted 2 × 3 repeated measures MANOVA's. Results showed a significant effect for time, with partial eta squared ranging from ηp2 = 0.647 to ηp2 = 0.692, for specific phobia, yet no significant interaction effects were found. CONCLUSION: No significant differences were found when VRET with YOH or a beta-blocker was compared to VRET with a non-active placebo. Implications for clinical practice and future research are discussed.

[The new 2017 European society of cardiology (ESC) guidelines: important changes for introduction into clinical practice]. / Novye rekomendatsii Evropeiskogo obshchestva kardiologov (ESC) 2017 g.: vazhnye izmeneniia dlia vnedreniia v klinicheskuiu praktiku.

The paper gives an overview of the European Society of Cardiology (ESC) guidelines updated in 2017. The revised and amended guidelines for areas, such as dual antiplatelet therapy (DAT), treatment of patients with ST-segment elevation myocardial infarction (STEMI), and management of patients with valvular heart disease and peripheral artery disease, were presented in late summer of this year. The authors of this paper present an independent analysis and discussion of new data on the key issues of diagnosis and treatment in patients in the above areas. The recommendations on DAT pay special attention to the timing of the therapy and to the choice of its drugs. The updated data on the treatment of patients with STEMI accurately determine the time to percutaneous coronary interventions, approaches to revascularization; the updates touch upon fibrinolytic therapy and new approaches to lipid-lowering therapy too. Recommendations for the management of patients with peripheral artery atherosclerosis propose for the first time a section devoted to the choice of antiplatelet therapy (an antiaggregant and/or an anticoagulant) depending on the clinical situation.

Characteristics of successful technological interventions in mental resilience training.

In the last two decades, several effective virtual reality-based interventions for anxiety disorders have been developed. Virtual reality interventions can also be used to build resilience to psychopathology for populations at risk of exposure to traumatic experiences and developing mental disorders as a result, such as for people working in vulnerable professions. Despite the interest among mental health professionals and researchers in applying new technology-supported interventions for pre-trauma mental resilience training, there is a lack of recommendations about what constitutes potentially effective technology-supported resilience training. This article analyses the role of technology in the field of stress-resilience training. It presents lessons learned from technology developers currently working in the area, and it identifies some key clinical requirements for the supported resilience interventions. Two processes made up this research: 1) developers of technology-assisted resilience programs were interviewed regarding human-computer interaction and system development; 2) discussions with clinicians were prompted using technology-centered concept storyboards to elicit feedback, and to refine, validate and extend the initial concepts. A qualitative analysis of the interviews produced a set of development guidelines that engineers should follow and a list of intervention requirements that the technology should fulfill. These recommendations can help bridge the gap between engineers and clinicians when generating novel resilience interventions for people in vulnerable professions.

Virtual reality exposure therapy does not provide any additional value in agoraphobic patients: a randomized controlled trial.

BACKGROUND: A number of studies have demonstrated the efficacy of virtual reality exposure therapy (VRET) in specific phobias, but research in seriously impaired patients with agoraphobia is lacking. In this randomized controlled trial with patients with agoraphobia and panic disorder, VRET and exposure in vivo were compared in terms of outcome and processes involved. METHODS: Patients with panic disorder with agoraphobia (n = 55) were randomly assigned to receive 4 sessions of cognitive behavioral therapy (CBT) followed by either 6 sessions of VRET or 6 sessions of exposure in vivo or to a waiting list control condition. RESULTS: Analyses showed that both active treatment packages were significantly more effective than no treatment and that no differences between VRET and exposure in vivo were found in three out of four outcome measures. On the panic disorder severity scale, however, CBT plus exposure in vivo was more effective than CBT plus VRET. The results show clear synchrony of temporal processes involved in VRET and exposure in vivo on weekly avoidance measures and cognitive measures. Further, it was shown that initial changes in agoraphobic cognitions during the CBT phase predicted later changes in agoraphobic avoidance behavior. CONCLUSION: These data support the notion that therapeutic processes involved might be the same in VRET and exposure in vivo. However, given the slight superiority of exposure in vivo above VRET, the costs involved in the implementation of VRET and the lack of long-term follow-up, VRET cannot yet be recommended for patients with agoraphobia.

Trauma and suicidality in war affected communities.

PURPOSE: The aim was to assess whether experiences of war trauma remain directly associated with suicidality in war affected communities when other risk factors are considered. MATERIALS AND METHODS: In the main sample 3313 participants from former Yugoslavia who experienced war trauma were recruited using a random sampling in five Balkan countries. In the second sample 854 refugees from former Yugoslavia recruited through registers and networking in three Western European countries. Sociodemographic and data on trauma exposure, psychiatric diagnoses and level of suicidality were assessed. RESULTS: In the main sample 113 participants (3.4%) had high suicidality, which was associated with number of potentially traumatic war experiences (odds ratio 1.1) and war related imprisonment (odds ratio 3) once all measured risk factors were considered. These associations were confirmed in the refugee sample with a higher suicidality rate (10.2%). DISCUSSION AND CONCLUSIONS: Number of potentially traumatic war experiences, in particular imprisonment, may be considered as a relevant risk factor for suicidality in people affected by war.

Course of post-traumatic stress disorder following war in the Balkans: 1-year follow-up study.

BACKGROUND: Prevalence rates of post-traumatic stress disorder (PTSD) following the experience of war have been shown to be high. However, little is known about the course of the disorder in people who remained in the area of conflict and in refugees. Method We studied a representative sample of 522 adults with war-related PTSD in five Balkan countries and 215 compatriot refugees in three Western European countries. They were assessed on average 8 years after the war and reinterviewed 1 year later. We established change in PTSD symptoms, measured on the Impact of Events Scale - Revised (IES-R), and factors associated with more or less favourable outcomes. RESULTS: During the 1-year period, symptoms decreased substantially in both Balkan residents and in refugees. The differences were significant for IES-R total scores and for the three subscales of intrusions, avoidance and hyperarousal. In multivariable regressions adjusting for the level of baseline symptoms, co-morbidity with depression predicted less favourable symptom change in Balkan residents. More pre-war traumatic events and the use of mental health services within the follow-up period were associated with less improvement in refugees. CONCLUSIONS: Several years after the war, people with PTSD reported significant symptom improvement that might indicate a fluctuating course over time. Co-morbid depression may have to be targeted in the treatment of people who remained in the post-conflict regions whereas the use of mental health services seems to be linked to the persistence of symptoms among refugees.

Lead exposure and intelligence in 7-year-old children: the Yugoslavia Prospective Study.

For a prospective study of lead exposure and early development, we recruited pregnant women from a lead smelter town and from an unexposed town in Yugoslavia and followed their children through 7 years of age. In this paper we consider associations between lifetime lead exposure, estimated by the area under the blood lead (BPb) versus time curve (AUC7), and intelligence, with particular concern for identifying lead's behavioral signature. The Wechsler Intelligence Scales for Children-Version III (WISC-III) was administered to 309 7-year-old children, 261 of whom had complete data on intelligence, blood lead, and relevant sociodemographic covariates (i.e., Home Observation for the Measurement of the Environment (HOME), birth weight, gender, sibship size, and maternal age, ethnicity, intelligence, and education). These showed anticipated associations with 7-year intelligence, explaining 41-4% of the variance in Full Scale, Performance, and Verbal IQ. Before covariate adjustment, AUC7 was unrelated to intelligence; after adjustment, AUC7 explained a significant 2.8%-4.2% of the variance in IQ. After adjustment, a change in lifetime BPb from 10 to 30 micro/dl related to an estimated decrease of 4.3 Full Scale IQ points; estimated decreases for Verbal and Performance IQ were 3.4 and 4.5 points, respectively. AUC7 was significantly and negatively related to three WISC-III factor scores: Freedom from Distractibility, Perceptual Organization, and Verbal Comprehension; the association with Perceptual Organization was the strongest. Consistent with previous studies, the IQ/lead association is small relative to more powerful social factors. Findings offer support for lead's behavioral signature; perceptual-motor skills are significantly more sensitive to lead exposure than are the language-related aspects of intelligence.

Consequences of lead exposure and iron supplementation on childhood development at age 4 years.

For a prospective study of lead exposure and early development, we recruited pregnant women from a smelter town and a nonlead-exposed town in Yugoslavia and followed them and their children through age 4. For 332 children seen at age 4, mean scores on the McCarthy Scales General Cognitive Index (GCI) in the exposed and nonexposed towns were 81.3 and 86.6, respectively; geometric mean blood lead concentrations (BPb) were 39.9 and 9.6 micrograms/dl, respectively. Potential confounders included the quality of the HOME environment; maternal age, intelligence, education, and language; birthweight and gender. These showed predictable associations with 4-year intelligence, accounting for 42.7% of the variance in GCI. Following adjustment for these variables and for concurrent Hgb, we found significant independent adverse associations between GCI and BPb's, measured at 6-month intervals since birth. At age 4, BPb accounted for an incremental 3.5% of the variance in GCI, such that the estimated loss in GCI associated with an increase in BPb from 10-25 micrograms/dl was 3.8 points. The Perceptual-Performance subscale of the McCarthy was most sensitive to Pb exposure, a result consistent with findings from prospective studies in Boston and Port Pirie.

Independent effects of lead exposure and iron deficiency anemia on developmental outcome at age 2 years.

For a prospective study of lead exposure, iron status, and infant development, we recruited infants living in a smelter town and a non-lead-exposed town in Kosovo, Yugoslavia. Among 392 infants assessed at age 2 years, the mean Mental Development Index (MDI), Bayley Scales of Infant Development, was 105.2. At age 2 years, geometric mean blood lead concentrations were 35.5 and 8.4 micrograms/dl, respectively, among infants from the exposed and nonexposed towns. After controlling for variables associated with MDI, we found significant independent associations for both blood lead and hemoglobin concentrations. For example, a rise in blood lead concentration at age 2 years from 10 to 30 micrograms/dl was associated with an estimated 2.5 point decrement in MDI (p = 0.03); statistically nonsignificant decrements were associated with blood lead levels measured at birth and at 6, 12, and 18 months of age. A decrease in hemoglobin concentration at 18 months of age from 12 to 10 gm/dl was associated with an estimated 3.4 point decrement in MDI (p = 0.02); the latter association was present in both towns, suggesting that it was due to iron deficiency anemia independent of lead exposure. The findings suggest that the brain is vulnerable to the effects of both lead exposure and anemia before 2 years of age. On a global basis, the developmental consequences of anemia may exceed those of lead exposure.
