Resume A retrospective analysis of the screening results was carried out (970 subjects of the cohort underwent an in-depth (4-fold) examination (at each visit: ultrasound examination of the thyroid gland, determination of the levels of thyroid-stimulating hormone (TSH) in the blood serum and antibodies to thyroid peroxidase (TPOAb), examination by an endocrinologist) for thyroid diseases. Medical examinations (visits) were carried out every 2 years.It was noted that within the cohort subjects, the most common clinical and laboratory variant of AIT was subclinical with preserved size and function of the thyroid gland or its transient decrease. The frequency of occurrence of the atrophic form of AIT is minimal (only 2/71 patients had a thyroid volume less than 6 ml) as well as the hypertrophic form (in 5/71 cases of AIT the thyroid volume exceeded 24 ml).Analysis of the combination of laboratory and instrumental criteria showed the dependence of the diagnosis of AIT on one of two examinations: Ultrasound (decreased echogenicity) or increased TPOAb. The proportion of each criterion was almost equal (echogenicity was decreased in 10 cases – 14,1%; TPOAb was increased in 16 cases – 22,5%). In most cases (43 cases – 60,6%) there was a combination of two criteria (decreased echogenicity and increased TPOAb). In one case (1,4%), against the background of an increased ratio of antibodies to thyroid peroxidase, an increased level of TSH was noted; ultrasonographic signs were normal. In the second case, against the background of decreased echogenicity of the thyroid gland and low TSH levels, ratio of antibodies to thyroid peroxidase is increased. In all cases, the patients did not report any clinical symptoms, i.e. it manifested as a subclinical form. The TSH level (in 70/71 cases) was within the normal range (0,3-4,0 mIU/l), but its level was significantly higher in patients with AIT (2,4±0,12 mIU/l) than in healthy individuals (TPOAb – normal and thyroid echogenicity – normal) 1,6±0,02 mIU/l; p<0,001.The simultaneous presence of high concentrations of TPOAb in the blood serum and sono -graphic criteria of AIT, including decreased echogenicity of the thyroid gland, increases after 2 years the risk of primary hypothyroidism (PHT) by 12,8 (5,19-31,61) times (p<0,001), in the case of TPOAb content in the blood serum – 29,9 IU/ml and higher, 9,4 (3,86-23,11) times – when the concentration of these autoantibodies TPOAb is more than 60 IU/ml.

Purpose: Clinical and neuropsychiatric assessment of the state of the cognitive functions of clean up workers of the accident at the Chernobyl nuclear power plant.Comparative examination of the cognitive functions of a group of clean up workers of the consequences of the Chernobyl accident, suffering from non-psychotic psychoorganic syndrome and patients with of cerebrovascular brain damage, using clinical, clinical-metric and neuropsychological methods. Psychopathological and neuropsychological assessment of their condition, correlation of neuropsychological and clinical-psychopathological manifestations of the identified disorders.The study revealed a wide range of cognitive impairments; at the remote stages, they dem onstrate an increase in cognitive impairment with the inclusion in the neuropsychological profile of predementia signs of the «Alzheimer’s» type. The predominance of violations of the regulatory mechanisms of cognitive functions over operational, predominantly neurodynamic, was noted. An increase in psycho-organic symptoms occurring against the background of somatic disorders can provoke previously unmanifested signs of neurodegenerative processes. Conative (motivational) disorders are also characteristic of the DS subgroup and are associated with altered affective mechanisms that are available for recovery as affective disorders are reduced. The structure of the clinical state of patients with LPA gravitates towards the psycho-pathological and neuropsychological profile of the CDS subgroup and is determined by the inclusion of deep structural mechanisms of cognitive impairment. The loss or decline in cognitive capabilities is acutely and painfully experienced in the LPA group; perhaps, there is not a true loss of skills, but some overvalued processing of the existing decline in professional level and household self-service abilities.

Objective:To evaluate the influence of gingival exposure on smile attractiveness.Methods: Photograph of one male and female volunteer with gummy smile, ideal occlusion and no dental anomalies were taken and manipulated on the computer with different gingival exposure levels ranging from +4mm to -4mm. The photographs were then printed and numbered 1-10 [Male=1-5 and Female=6-10] with the relevant gingival exposure 1= +4 mm, 2= +2 mm, 3= 0 mm, 4= -2 mm, 5= -4 mm, 6= +4 mm, 7= +2 mm, 8= 0 mm, 9= -2 mm and 10= -4 mm. Assessment was independently done on each picture using 5point attractiveness scale scored as very attractive, attractive, neither attractive nor unattractive, unattractive, very unattractive.Results: The highest mean attractiveness was reported on +4mm and +2mm gingival exposure for the male picture while +2mm and +4mm gingival exposure for the female picture. The mean attractiveness for picture 1 was significantly higher in younger than older participants (4.95±0.02 versus 4.81±0.02). The mean attractiveness for picture 4 was significantly higher in dental professionals than laypersons (3.96±0.08 versus 3.09±0.06). The mean attractiveness for picture 5 was significantly higher in younger than older participants (2.04±0.06 versus 1.53±0.04) and also in laypersons than dental professionals (1.79±0.04 versus 1.34±0.05). The mean attractiveness for picture 6 was significantly higher in younger than older participants (3.18±0.09 versus 2.83±0.07), males than females (3.10±0.08 versus 2.84±0.08) and also in lay persons than dental professionals (3.16±0.06 versus 2.01±0.10). The mean attractiveness for picture 7 was significantly lower in younger than older participants (2.90±0.07 versus 3.09±0.05). The mean attractiveness for picture8 was significantly higher in younger than older participants (2.03±0.05 versus 1.85±0.04) and also in laypersons than dental professionals (1.68±0.06 versus 1.96±0.03). The mean attractiveness for picture 9 was significantly lower in younger than older participants (1.39±0.05 versus 1.54±0.03). The mean attractiveness for picture 10 was significantly higher in dental professionals than laypersons (1.36±0.06 versus 1.23±0.02).Conclusion: Smile attractiveness influenced by the gingival exposure had major variations between younger and older participants, moderate variation between dental professionals and laypersons have similar opinions regarding the gingival exposure between gender.

Published: December 2023

The problem of variance vector estimation using multi-auxiliary variables is not quite often considered in the literature. In the present study, we propose a multivariate ratio estimation approach for estimating a vector of variances in two-phase sampling using a vector of variables, following the situation if the desired parameters are available only for some of the auxiliary variables. Some special cases of the proposed generalized multivariate variance estimator have also been discussed. Expressions of the bias, and generalized variance has been derived. With the help of real-life data, the applicability of the proposed multivariate variance estimator has been given, and it is shown that the proposed multivariate estimator is more efficient than the modified versions of multivariate variance estimators. A simulation study has also been carried out to show that the proposed estimator surpasses the modified version of multivariate estimators.

Background
Hemolytic anemia (HA) is a serious health condition resulting from reduced erythrocytes’ average life span. Echinochrome (Ech) is a dark-red pigment found in shells and spines of sea urchins.

Aim
Studying the potential therapeutic effect of Ech on phenylhydrazine (PHZ)-induced HA in rats.

Methods
Eighteen rats were divided into three groups (n = 6): the control group, the phenylhydrazine-induced HA group and the Ech group, injected intraperitoneally with PHZ and supplemented with oral Ech daily for 6 days.

Results
Ech resulted in a considerable increase in RBCs, WBCs, and platelets counts, hemoglobin, reduced glutathione, catalase, and glutathione-S-transferase levels, and a significant decrease in aspartate & alanine aminotransferases, alkaline phosphatase, gamma-glutamyl transferase, bilirubin, creatinine, urea, urate, malondialdehyde & nitric oxide levels in anemic rats. Histopathological examination of liver and kidney tissue samples showed marked improvement.

Conclusion
Ech ameliorated phenylhydrazine-induced HA with a hepatorenal protective effect owing to its anti-inflammatory and antioxidant properties.

Field experiment was conducted at the BINA Sub-Station, Ishurdi to investigate the integrated effect of vermicompost and chemical fertilizers on the yield and yield contributing characters of brinjal. Seven treatments were used in the experiment. The treatments used in the experiments were T1: Control; T2: Recommended fertilizer (RF); T3: 75% RF + 3 tha-1 Vermicompost (VC); T4: 75% RF + 5 tha-1 VC; T5: 50% RF + 3 tha-1 VC; T6: 50% RF + 5 tha-1 VC; T7: 5 tha-1 VC. The experiment was conducted in a Randomized Complete Block Design with three replications. The treatment T4 (75% RF + 5 tha-1) gave maximum yield (7.8 tha-1) of brinjal followed by the treatment T6 (6.88 tha-1). But the treatments T3 and T5 gave identical yields of brinjal. Therefore, fertilizer doses of N101.25, P27, K52.5, S3.75, Zn0.75 kgha-1 with VC @ 5 tha-1 for Ishurdi could be adopted in the cultivation of brinjal for getting maximum yields.
Role of Diffusion-Weighted Magnetic Resonance Imaging in Differential Diagnosis of Splenic Focal Lesions
Authors: El-Bagoury Shereen Essam , Hefeda Mohamed Mohamed , Teama Atef Hammad 
Published: December 2023

Background: In computed tomography (CT) and magnetic resonance imaging (MRI), enhancement patterns observed following the injection of a contrast agent are typically used to non-invasively distinguish between malignant and benign localised splenic lesions (MRI). Diffusion-weighted magnetic resonance imaging (DWI) is useful for staging and subsequent imaging of malignant tumours because it gives function information and may be utilised to identify and characterise pathologic processes, including malignant tumours.
Aim of the Work: This study's main objective was to assess the extra value of diffusion-weighted MRI in the detection and classification of splenic localised lesions.
Patient and Methods: Thirty patients with splenic focal lesions, of both gender, participated in this prospective investigation. All patients had complete information about the patient, examination findings, including an abdominal and general examination, an ultrasound, an abdominal MRI, and a DWI investigation.
Results: Considering the mean ADC value of the examined group, we discovered that the benign lesions group's mean ADC value was (1.46) x 10-3 sec/mm2, whereas the malignant lesions group's mean ADC value was (0.73) x 10-3 sec/mm2. In the individuals under study, we discovered a strong correlation between clinicopathological results and DW-MRI data. (p<0.001). With a sensitivity of 83.33% and specificity of 94.44%, the kind of lesion was a statistically significant predictor of ADC values.
Conclusions: When used with conventional MRI, diffusion-weighted imaging enhances the ability to distinguish between splenic localised lesions. To verify our findings and resolve any discrepancies with the literature, more research is required.

ImportancePatient education is a critical aspect of atrial fibrillation (AF) management. However, there is limited time to provide effective patient education during routine care, and resources available online are of variable quality.ObjectiveTo determine whether clinician-led creation of video-based AF education is feasible and improves knowledge of AF.Design, Setting, and ParticipantsThis single-center randomized clinical trial was conducted between 2020 and 2022. Outcomes were assessed prior to their clinic visit and 2 and 90 days after the visit by blinded assessors. Participants included adults with AF and congestive heart failure, hypertension, age at least 75 years (doubled), diabetes, prior stroke or transient ischemic attack or thromboembolism (doubled), vascular disease, age 65 to 74 years, and sex category scores of 1 or greater presenting for routine care at publicly funded outpatient cardiology clinics within a tertiary teaching hospital. Individuals too unwell to participate or with limited English were excluded. Data were assessed as intention to treat and analyzed from December 2022 to October 2023.InterventionIntervention participants viewed a series of 4 videos designed and narrated by clinicians that aimed to improve understanding of AF pathophysiology, clinical presentation, diagnosis, and management. After viewing the videos, participants received weekly email links to review the videos. The control group received usual care.Main Outcomes and MeasuresThe prospectively selected primary outcome was AF knowledge at 90 days, measured by the validated Jessa Atrial Fibrillation Knowledge Questionnaire (JAFKQ).ResultsAmong 657 individuals screened, 208 adults with AF were randomized (mean [SD] age, 65.0 [12.2] years; 133 [65.2%] male) and included in analysis. Participants were randomized 1-to-1, with 104 participants in the control group and 104 participants in the video intervention group. At 90 days after the baseline clinic visit, intervention participants were more likely to correctly answer JAFKQ questions than control participants (odds ratio [OR], 1.23 [95% CI, 1.01-1.49]). The difference was greater in participants who remotely accessed videos on 3 or more occasions during the study (OR, 1.46 [95% CI, 1.14-1.88]).Conclusions and RelevanceIn this randomized clinical trial of patients with AF, remotely delivered, clinician-created video education improved medium-term AF knowledge beyond usual care of standard in-clinic education. The improvement demonstrated in this study provides support for the implementation of clinician-created educational resources across the care continuum. Further work is needed to assess for impact on clinical outcomes.Trial Registrationanzctr.org.au Identifier: ANZCTRN12620000729921

Published: December 2023

ImportanceThe global prevalence of myopia has shown a steady increase over recent decades, with urban areas seemingly experiencing a more significant impact.ObjectiveTo assess the association between urbanization and the prevalence, incidence, progression, and severity of myopia.Design, Setting, and ParticipantsThis cohort study included students in grades 1 to 6 in Tianjin, China, who underwent 3 vision examinations conducted over a 2-year period, from March 1, 2021, to March 31, 2023. Participants from grades 1 to 4 completed the 2-year follow-up.ExposuresUrban living environmentMain Outcomes and MeasuresThe association of urbanization with the incidence, progression, prevalence, and severity of myopia. To quantify urbanization, an urban score was constructed using satellite data and an iterative exploratory factor analysis.ResultsOf 177 894 students (51.7% male; mean [SD] age, 10.27 [1.75] years) included in the study, 137 087 students (52.3% male; mean [SD] age, 8.97 [1.21] years) were followed up for 2 years. A positive association was identified between myopia incidence and urbanization. Specifically, each 1-unit increment in the urban score was associated with an increased risk of myopia over a 1-year period (odds ratio [OR], 1.09; 95% CI, 1.01-1.15; P = .02) and a 2-year period (OR, 1.53; 95% CI, 1.50-1.57; P &amp;lt; .001). Conversely, each 1-unit increase in the urban score was associated with a significant decrease in myopia progression at 1 year (OR, 0.84; 95% CI, 0.82-0.86; P &amp;lt; .001) and 2 years (OR, 0.73; 95% CI, 0.70-0.75, P &amp;lt; .001). In a cross-sectional data analysis, the urban score was positively associated with myopia prevalence (OR, 1.62; 95% CI, 1.08-2.42; P = .02) and negatively associated with myopia severity, as indicated by spherical equivalent refraction (OR, 1.46; 95% CI, 1.07-1.99; P = .02).Conclusions and RelevanceThis study exploring urban living environments and myopia revealed dual associations of urban living with both the incidence and the progression of myopia. The observed patterns emphasize the urgency of promptly implementing myopia control strategies in less urbanized regions, where myopia progression may be accentuated.
