Published: September 2024

Abstract

Introduction: In the presented research, we characterized the contralateral effect after applying capacitive and resistive transfer of energy (TECAR) in the treatment of active myofascial trigger point (MTrP). In order to assess the contralateral effect, we used the infrared thermovision method. We hypothesize that by means of thermal imaging studies, we will be able to present and confirm the contralateral effect which can be important in establishing the MTrP treatment protocol with the use of TECAR.

Material and methods: In the study, thermographic imaging was performed on a group of 6 volunteers with an age range [25-45] years (mean age: 32.3 years ± 9.83 years) who were randomly selected for the study from among people practicing recreational sports and showing the clinical presence of active MTrP in the upper trapezius muscle (UT).

Results: On both sides, the reference area (side untreated) and the target area (side treated), there was an increase in the percentage changes of isotherms. These results indicate the presence of a contralateral effect. The use of TECAR therapy ipsilaterally in the treatment of MTrP in UT results in an increase of temperature on the symmetrical body part and it may be connected with the presence of vascular contralateral effect on the untreated side.

Conclusions: These changes were investigated by IR which, as our research shows, can be an effective form of assessing the therapeutic effects of TECAR in MTrP treatment.

Abstract
Glycerol is a versatile substance used in food, beverages, cosmetics, and technical applications. It can be derived from fats and oils through 4 different reactions, including: transesterification, directed hydrogenation, hydrolysis, and saponification. Glycerol derived from fat hydrolysis yields superior quality and quantity when compared to saponification. The resulting glycerol water is purified and concentrated through evaporation to yield crude glycerol with a concentration of 86-88%. Two distinct methods are recognized for further improving quality of glycerol: distillation, and the purification of glycerol water through the ion exchange process followed by evaporation. The goal of this research was to improve the purification process of glycerol, for obtaining premium-quality glycerol without the need for distillation, through the utilization of cations. Several combinations of activated carbon and clay were tested, and it was determined that a combination of 70:30 yielded the optimal results, considering the amount of glycerol and ash content. Technological parameters such as reaction durations, pH, and process temperatures were investigated, and it was discovered that the appropriate combination was a process duration of more than 40 minutes, a pH value of 2, and a temperature of 70°C. Besides, it was also determined that the concentration and quality of glycerol derived from cottonseed oil can be enhanced through distillation or purification with cationite. Moreover, different concentrations of glycerol on the elaboration of gingerbread were tested, and the conclusion is that adding 5% of the resulting glycerol to the gingerbread recipe could ensure better preservation of its quality during its shelf life.

Published: September 2024

Abstract
Excessive intake of saturated fatty acids and physiologically imbalanced amino acids worsens the patient’s psychotic condition, creating the risk of developing psychosis and other comorbidities. Therefore, to ensure the optimal amount of amino acids and improve the psychotic state, pea protein isolate is an alternative to nutritional supplementation. The aim of the study was to analyse the amino acid profile of pea protein isolates and their solubility to evaluate their potential for the development of beverages for patients with psychiatric disorders. In the study, the amino acid profile analysis of organic and conventional pea protein isolates was performed using high performance liquid chromatography mass spectrometry. To evaluate solubility, pea protein isolates were treated in an ultrasonic bath and at different pH concentrations. The results showed that organic pea protein isolate showed a higher composition of essential amino acids (41.27%) and semi-essential amino acids (8.37%) than conventional pea protein isolate. Organic pea protein isolate was able to provide a more appropriate amino acid composition to meet the amino acid needs of patients with psychiatric disorders. Organic and conventional pea protein isolates had higher solubility in the ultrasonic bath of 20 min and in the alkaline environment. The solubility between the two pea protein isolates was not significantly different, but the ultrasonic bath treatment and different pH concentrations were significant, which gave insight and further application in beverage production.

Abstract
The microbiome’s role in ulcerative colitis pathogenesis is established. The influence of lifestyle on gut microbiome composition remains unclear, and interplay with COVID-19 disease warrants investigation. In a cross-sectional study conducted from June to December 2021, 49 outpatients from Rīga East Clinical University Hospital were included. Patients were categorised based on COVID-19 disease status (positive vs. negative) within the preceding six months. Lifestyle factors (smoking, alcohol consumption, physical activity, stress levels, and dietary patterns) were assessed and evaluated. Taxonomic classification of gut microbiome metagenome data was performed using MetaPhlAn v.2.6.0, with subsequent analysis conducted using SPSS 20.0. Thirty-one (63%) were male, and 18 (37%) were female patients. Fourteen patients (28.6%) tested positive for COVID-19. Gut microbiome composition differences were not observed between COVID-19 disease groups. Twenty-four (49%) patients engaged in sports activities and 30 (61.2%) patients reported a history of smoking. No significant microbiome differences were observed in groups regarding physical activity or smoking. Thirty-five (71.4%) were alcohol users, for whom Firmicutes abundance was significantly higher compared to non-users, p = 0.041. Patients reporting lower stress levels (18, 36.7%) exhibited higher Actinobacteria abundance compared to those with higher stress levels (31, 63.3%), p = 0.03. COVID-19 disease status did not affect gut microbiome composition, alcohol consumption and stress levels demonstrated significant associations.

Abstract
This clinical case is about a 50-year old woman, a refugee from Ukraine, without known epidemiological risk factors, with newly diagnosed human immunodeficiency virus-1 (HIV-1) infection in acquired immune deficiency syndrome (AIDS) stage. Qesophageal candidiasis as an indicator disease of HIV in this case was the first diagnosis that promoted further investigation, revealing both primary HIV infection and sequentially other opportunistic infections — cytomegalovirus, Epstein Barr virus, and miliary tuberculosis. Oesophageal candidiasis was visualised by the oesophagogastroduodenoscopy method, which was initially performed due to detected anaemia to rule out bleeding from the gastrointestinal tract. Deep immunosuppression was provided to this patient and this led to the development of miliary tuberculosis, worsening the prognosis. The patient was prescribed treatment for several opportunistic infections, also anti tuberculosis treatment, as well as combined antiretroviral treatment, which stabilised the situation. In this case our patient developed odynophagia and dysphagia, common complications of oesophageal candidiasis, so she had to receive nutrition through a nasogastric tube.

Published: September 2024

Abstract
Leptospirosis is a widespread and potentially fatal zoonosis that is endemic in many tropical regions. It is the most common zoonotic infection in the world, but a rare disease in Latvia. The clinical manifestations and the severity of leptospirosis are highly variable. This case report describes a 64-year-old male without comorbidities, who was admitted to Rīga East University Hospital in the Gastroenterology Department due to expressed jaundice, weakness, and acute kidney injury. The initial inpatient clinical diagnosis was initially acute alcoholic hepatitis, as the patient had consumed alcohol a month before hospitalisation. The clinical and laboratory picture of the patient was dominated by significant hyperbilirubinemia, a relatively small increase in liver transaminases, preserved synthetic liver function, acute kidney failure in the polyuria phase, and severe thrombocytopenia. During hospitalisation, the study of anamnesis and the results of laboratory tests gave grounds for suspecting the diagnosis of leptospirosis, which was subsequently serologically confirmed. Routine laboratory tests are not specific for diagnosing leptospirosis. Diagnosis is made on the basis of the doctor’s request and clinical examination, as well as on the basis of blood and urine culture and serological tests. Early initiation of antibiotic therapy plays an important role in controlling infection and reducing mortality.

Abstract

Introduction
The relationship between cardiac deformation by 2D speckle tracking, hypertrophy, and the extent of late gadolinium enhancement (LGE) in patients with hypertrophic cardiomyopathy remains uncertain. Our study aims to compare left ventricular global longitudinal strain (GLS) with the extent of LGE and to determine a relationship between GLS and hypertrophy.

Methods
We conducted a descriptive cross-sectional single-center study that included patients aged 16 or above. Participants underwent echocardiography and cardiac MRI. GLS was assessed through 2D speckle tracking. LV mass index and LGE extent (LGE% = LGE volume/ LV mass) were calculated from MRI. Patients were divided into three groups based on LGE extent for analysis (LGE extent = 0; < 15%; ≥ 15%),

Results
Forty-two patients were included, 15 having a LGE extent ≥ 15%, 16 having an extent < 15%, and 11 having no LGE. Patients with LGE ≥ 15% had significantly lower global longitudinal strain, higher LV mass index, and higher maximal wall thickness compared to those without LGE (p= 0.016, p=0.025, and p=
0.003, respectively). A GLS cutoff value of -13.95 % predicted a LGE extent ≥15% with a specificity of 63% and sensitivity of 66.7%. Area Under the Curve (AUC) of 0.691 (95% CI 0.515 - 0.868) p=0.042. Patients with higher LV mass index had lower GLS (p<0.0001).

Conclusions
The study suggests a correlation between GLS, LGE extent, and hypertrophy in HCM patients. These findings indicate that GLS could be a promising tool for sudden death risk stratification as the LGE extent.

Affordable housing is not merely about cost but encompasses quality, safety, and accessibility. The shortage of affordable housing perpetuates cycles of poverty, negatively impacting well-being. Utilizing scientometric techniques —co-authorship analysis, citation network analysis, and keyword co-occurrence analysis— on Scopus data from 1999 to 2024, and employing the VOSviewer tool, the aim of this study is to provide a comprehensive understanding of housing affordability by integrating both monetary and non-monetary factors and identifies 1) the co-authorship, co-occurrence, and countries’ collaboration, and 2) the most cited article in the field. The results reveal key contributors in affordable housing research, highlight influential works, and map publishing trends. The outcomes show that nine different groups exist and actively collaborate worldwide. Waddell’s work, with 873 citations, is the most cited, followed by Monahan with 421 citations. The analysis highlights significant thematic clusters, such as the integration of technological advancements, health considerations, and policy changes in affordable housing research. The study underscores the critical role of social and environmental sciences in addressing housing equity and community well-being. By mapping the current research landscape and forecasting future trajectories, this study provides critical insights for guiding future research, policy development, and societal progress in affordable housing.

OBJECTIVES: To (1) investigate whether different labels for neck pain after a motor vehicle crash (MVC) influenced recovery expectations and management beliefs, (2) explore reasons for low recovery expectations and greater likelihood for lodging a claim, and (3) explore the moderating effect of neck pain history and sociodemographic characteristics. DESIGN: Online randomized experiment with nested qualitative content analysis. METHODS: We randomized 2229 participants from the general population (mean age: 46.7 ± 17.5 years; 72.4% females; 66% with previous or current neck pain; 10% with an MVC experience) to read 1 of 5 scenarios describing a patient with neck pain after an MVC, each was labeled as whiplash injury, whiplash-associated disorder, posttraumatic neck pain, neck pain, or neck strain. The primary outcome was recovery expectations, rated on a 0- to 10-point scale. RESULTS: Participants allocated to whiplash-associated disorder or neck pain had lower recovery expectations than those allocated to neck strain (adjusted mean difference [95% confidence interval]: −0.5 [−0.9 to −0.1] for both comparisons). Whiplash-associated disorder led to more recovery uncertainty, while neck pain led to greater doubt about the health care provider. Most secondary outcomes showed significant but small differences. Participants allocated to neck strain were less inclined to claim than those allocated to whiplash-associated disorder or whiplash injury due to less perceived need for financial support. Neck pain history moderated labeling effects on recovery expectations; household income moderated the claim intention. CONCLUSIONS: Labels for neck pain after an MVC influenced recovery expectations and management preferences. The clinical relevance of the small effects was unclear.

Assessment of accuracy of clinical blood loss estimation compared to actual blood loss during major surgeries
Authors: Aljannare Bashir Garba , Khalid Abdullahi 
Published: September 2024

Objectives:
This study aims to assess the accuracy of clinical blood loss estimation compared to actual blood loss (ABL) during major surgeries.

Materials and Methods:
Fifty patients undergoing major surgery for various indications were included in the study. They were assigned into two groups of 25 each as they came, Group C (clinical method group) and Group F (formula method). In Group C, blood loss estimation was carried out using the clinical method of blood loss estimation (gravimetric and visual methods) whereas, in Group F, the blood loss was obtained using the modified gross formula method. The data obtained from the study were analyzed electronically using the Statistical Package for the Social Sciences version 20.0 and these data were presented using relevant tables and figures. A comparison of blood loss between the two groups was determined using an unpaired Student t-test.

Results:
The mean hematocrit (HCT) before the surgery was 34.00 ± 0.52, whereas the mean HCT after the surgery was 29.00 ± 0.61. The mean drop in HCT was 5.00 ± 0.36. The mean ABL was 855.80 ± 83.17 mL. The mean blood loss estimated by the gravimetric method was 805.40 ± 392.72 mL, whereas the mean error of estimation by the gravimetric method was 50.40 ± 163.23 mL which was statistically not significant (P = 0.30). The mean blood loss by visual method was 650 mL ± 132.34. The mean difference between ABL and visual method of estimation was 205.60 mL, and this was statistically significant (P = 0.02).

Conclusion:
The gravimetric method and visual method of blood loss were the two clinical methods of blood loss estimation used in this study. The two clinical methods when compared to ABL, they underestimated the blood loss by 19.24% and 39.48%, respectively.
Sono-graphic Rim Sign in Postpartum Renal Cortical Necrosis: Experience at a Tertiary Care Centre
Authors: Kumar Adarsh , Rajput Meenakshi , Kumar Rajesh , Mahajan Sanjiv , Jain Chirag 
Published: September 2024

Background:
Kidney biopsy or contrast studies are required to diagnose acute renal cortical necrosis (RCN). Both procedures may be potentially delayed in the postpartum setting. Contrast-enhanced ultrasound (CEUS) is a potential alternative for these patients but remains limited in availability. Due to sparse literature and the rarity of RCN, the role of conventional B-mode ultrasound (USG) in diagnosing RCN remains unexplored.

Materials and Methods:
This retrospective study involved postpartum patients with RCN who underwent kidney biopsy at a tertiary care center. Medical records and B-mode USG kidney images of all 23 patients with postpartum RCN over the past 24 months were retrieved. Gray-scale B-mode USG images of the kidney were assessed for size, presence of sonographic hypoechoic rim, USG kidney timing, echogenicity, and cortico-medullary differentiation.

Results:
Among the 23 patients, sonographic hypoechoic rim was observed in 6 patients (26.1%). USG kidney timing ranged from 1.1 to 8 weeks, and kidney length varied from 9.0 to 10.8 cm. There were significant differences in mean USG kidney timing and mean kidney length between patients with and without hypoechoic rim (P= 0.020 and P= 0.036, respectively). The mean USG kidney timing was notably earlier in patients with sonographic rim signs than those without sonographic rim signs (2.5 ± 0.77 weeks and 4.81 ± 2.17 weeks, respectively).

Conclusion:
Despite its lower sensitivity, the sonographic rim sign is an important diagnostic feature of postpartum renal cortical necrosis. In point-of-care ultrasonography, it should be looked for early in the disease course, especially in cases of postpartum anuric acute kidney injury.

Published: September 2024

In this work, the influence of alpha particles, protons and gamma rays on the crystal structure and structural characteristics of n-type silicon (n-Si) single crystals was studied using X-ray diffraction. N-type silicon (KEF-40) was used for the study. The samples were irradiated with protons with a dose of 9×1014 cm-2 with an energy of 600 keV and a current of 1÷1.5 µA, irradiated with alpha particles with a dose of 6×1014 cm-2 with an energy of 800 keV and a current of 0.5÷1 µA and γ− 60Co quanta with a flux intensity of ~ 3.2×1012 quantum/cm2·s. Based on the results of X-ray diffraction analysis, it was established that distortions, vacancies and amorphization of lattice parameters that arose after irradiation lead to an increase in lattice parameters.
