Abstract

Background
The aim of our study was to assess the inter-observer variability in delineation of the gross tumour volume (GTV) of oesophageal cancer on magnetic resonance (MR) in comparison to computed tomography (CT) and positron emission tomography and CT (PET/CT).

Patients and methods
Twenty-three consecutive patients with oesophageal cancer treated with chemo-radiotherapy were enrolled. All patients had PET/CT and MR imaging in treatment position. Five observers independently delineated the GTV on CT alone, MR alone, CT with co-registered MR, PET/CT alone and MR with co-registered PET/CT. Volumes of GTV were measured per patient and imaging modality. Inter-observer agreement, expressed in generalized conformity index (CIgen), volumetric conformity index (VCI), planar conformity index (PCI) and inter-delineation distance (IDD) were calculated per patient and imaging modality. Linear mixed models were used for statistical analysis.

Results
GTV volume was significantly lower on MR (33.03 cm3) compared to CT (37.1 cm3; p = 0.002) and on PET/CT MR (35.2 cm3; p = 0.018) compared to PET/CT (39.1 cm3). The CIgen was lowest on CT (0.56) and highest on PET/CT MR (0.67). The difference in CIgen between MR (0.61) and CT was borderline significant (p = 0.048). The VCI was significantly higher on MR (0.71; p = 0.007) and on CT MR (0.71; p = 0.004) compared to CT (0.67). The PCI was significantly higher on CT MR (0.67; p = 0.031) compared to CT (0.64). The largest differences were observed in the cranio-caudal direction.

Conclusions
The highest inter-observer agreement was found for PET/CT MR and the lowest for CT. MR could reduce the difference in delineation between observers and provide additional information about the local extent of the tumour.

Abstract
This study investigates the wintering range and migratory patterns of the Song Thrush in North Africa, focusing on the Maghreb region. Despite the fact that this is the southernmost limit of its wintering range, comprehensive analyses of its geographic origin and spatial distribution are lacking. The research utilizes 840 records, representing the first comprehensive analysis of ringed bird recoveries in North Africa. Findings reveal that the Song Thrush is a common visitor to the Mediterranean belt of North Africa, with distinct migratory routes for different populations. Notably, Italy contributes significantly to the total number of recoveries. The study highlights North Africa as a wintering area for both long-distance migrants and partially migratory populations from Western and Central Europe.
An intriguing observation is the disproportionate concentration of recoveries in Algeria (89.6%), particularly in the Kabylie region, suggesting potential biases due to hunting and trapping activity. Temporal analyses indicate a decline in captured birds from the 1960s to the 2000s, possibly reflecting changes in hunting pressures across North Africa.
The seasonal distribution of recaptures shows a peak in January, emphasizing the thrushes’ southward movements within their wintering range. The study challenges previous assumptions of early spring migration, suggesting onset in the second 10-day period of February. Contrary to previous claims, our data do not support prenuptial movements from Kabylie to Tunisia. Instead, sedentary behaviour in wintering areas until March is suggested by both geographical coordinates and recovery data. Satellite transmitter data confirm departure dates in March for thrushes marked in December in Italy.
In summary, this study provides a concise overview of Song Thrush wintering dynamics in North Africa, offering insights into diverse migratory patterns and regional biases and challenging previously held assumptions about prenuptial movements and migration onset.

INTRODUCTION. The issue of a relapse-free treatment in herniology has not yet been resolved. Over the past few years due to the development and wider use of modern technologies, there has been an improvement in the quality of surgical care for patients with inguinal hernias. Approaches to preparation for surgical interventions, redistribution of surgical options and postoperative management of patients have also changed significantly.The OBJECTIVE of this work was to determine modern aspects of the treatment of patients with inguinal hernias and the effectiveness of various methods of surgical treatment in herniology, as well as to identify differences due to statistical heterogeneity in research results.METHODS AND MATERIALS. More than 2,000 domestic and foreign publications on the surgical treatment of inguinal hernias were subjected to preliminary analysis. Taking into account the inclusion and exclusion criteria, the review included 10 scientific studies published in domestic and foreign scientific journals from 2014 to 2022. We analyzed 2649 cases of surgical treatment of patients with inguinal hernias, assessing the results of treatment and the clinical effectiveness of various methods.RESULTS. When comparing methods of operations, the best results in terms of the frequency of relapses and the frequency of specific complications were obtained with transabdominal preperitoneal plastic surgery of inguinal hernias. The worst results in terms of the frequency of relapses were demonstrated by total extraperitoneal plastic surgery, in terms of the frequency of specific complications, the highest percentage belongs to Liechtenstein hernia repair. Taking into account the heterogeneity of patients in the studies, we can conclude that the use of transabdominal preperitoneal plastic surgery is a priority.CONCLUSION. The overall effectiveness of treatment of patients with inguinal hernias has significantly improved using modern principles of evidence-based medicine, standardized approaches to the management of surgical patients and the prevention of possible complications. Endovideosurgical operations widely introduced into practice all over the world have shown the best results in assessing the risk of relapses and specific postoperative complications. However, compared to other methods, the share of endovideosurgical operations is a smaller percentage.

INTRODUCTION. One of the most formidable complications in thoracic surgery is bronchopleural fistula after pneumonectomy. Main bronchus stump reinforcement during surgery is used as method of prevention of this complication. The question of the preferred plastic material remains debatable.The OBJECTIVE was to compare the results of myoplasty and diaphragmoplasty of the right main bronchus stump after pneumonectomy performed for destructive pulmonary tuberculosis.METHODS AND MATERIALS. A retrospective study from 2015 to 2022 was conducted. The study included 30 patients who were divided into 2 groups. Group 1 included 19 patients who underwent diaphragmoplasty; group 2 included 11 patients who underwent myoplasty. Patients were comparable in terms of sex, age, functional indices, and features of the course and prevalence of the underlying disease. The short-term and long-term results of surgical treatment were compared.RESULTS. Complicated course of the postoperative period was observed in 6 (31.6 %) patients in group 1 and in 5 (45.5 %) patients in group 2. Satisfactory immediate result in group 1 was achieved in 17 (89.5 %) patients, in group 2 – in 8 (72.7 %). In the remote period, the result of complex treatment of TB patients in group 1: successful treatment – 13 (68.5 %), ineffective treatment – 2 (10.5 %), loss to follow-up – 2 (10.5 %), lethal outcome – in 2 (10.5 %); in group 2: successful treatment – 8 (72.7 %), ineffective treatment – in 3 (27.3 %).CONCLUSIONS. Right-sided pneumonectomy in patients with destructive pulmonary tuberculosis with drug-resistant mycobacteria is accompanied by a high risk of main bronchus stump failure. The diaphragm and chest wall muscles are reliable materials for strengthening the main bronchus stump.

Published: October 2024

The OBJECTIVE was to retrospectively study the results of treatment of mediastinal bronchogenic cysts (MBC), to present a case of the formation of a cystobronchial fistula after a transbronchial cyst puncture.METHODS AND MATERIALS. MBC were diagnosed in 11 (20 %) of 55 patients with various mediastinal cysts. The diagnosis was confirmed by computed tomography data, in one case by a transbronchial puncture. All patients were operated on.RESULTS. MBC was asymptomatic in 8 cases (72.7 %). Neoplasm in the mediastinum was detected during fluorographic examination in 5 patients, with CT in 6 cases. The dimensions of the cysts according to CT data were 45.5±15.2mm and 39.3±17.5mm, respectively. MRI was performed in two patients due to comorbid pathology of the spine. A 60-year-old patient underwent a transbronchial biopsy with biopsy forceps for diagnostic aim, as a result of which the cyst cavity was opened, infected, and a cystobronchial fistula with a diameter of 2 mm was formed with constant coughing up the purulent contents of the cyst. After anti-inflammatory, antibacterial therapy, after a month and a half, the cyst was removed by thoracotomy due to a pronounced periproccess. Video-assisted thoracoscopic cystectomy was performed for 9 patients. One patient was underwent conversion to thoracotomy due to the adhesive process after a previously performed lobectomy. Exudative pleurisy developed from postoperative complications in one case.CONCLUSION. The main method of diagnosing MBC is computed tomography. The ultrasound-guided transbronchial needle puncture of a cyst can be used to clarify the diagnosis under antibiotic prophylaxis, but can lead to infection of the cyst. Thoracoscopic excision of MBC should be considered the first-line therapeutic option due to the risk of complications and the presence of clinical manifestations.

Background:Adult-onset aqueductal stenosis (AOAS) is an uncommon cause of hydrocephalus in adults. Its etiopathogenesis is poorly understood, with various proposed mechanisms, spectrum of presentation, and management. Very little has been reported on this anomaly in African literature. This study aimed to describe the pattern of presentation, clinical spectrum, and early outcomes following the shunt procedure in our population practice setting.Methods:This was a retrospective case series of patients with non-tumoral AOAS managed between 2008 and 2023 in a tertiary center in South-West Nigeria. Relevant demographic, clinical-radiologic, and outcome data were retrieved and analyzed.Results:There were seven males and one female. Their age ranged from 18 to 50 years. The duration of symptoms ranged from 3 to 120 months. All patients admitted having headaches; however, visual deterioration (n= 5) was the most common presenting symptom. Features of endocrinopathy (n= 1), cerebellar dysfunction (n= 2), cognitive deficit (n= 2), spontaneous cerebrospinal fluid leak (n= 1), and sphincteric dysfunction (n= 1) were also observed. The mean Evan’s index at the presentation was 0.43. Ventriculoperitoneal shunt (VPS) insertion was performed in seven patients with good outcomes. One patient opted for a referral. One patient had shunt revision 6 years later on account of shunt disconnection.Conclusion:AOAS is an infrequent cause of hydrocephalus in our setting, with most patients seeking medical consultation following visual deterioration. Proper evaluation of adults with long-standing headaches and associated features is advocated to avert total visual loss in this subgroup. VPS insertion is a viable treatment option with a good outcome.

This study aims to analyze the effect of providing commercial feed with the addition of ethanol extract of K. alvarezii seaweed flour on the growth of tilapia (O. niloticus). The research was carried out in July – October 2023 at the Aquaculture Reproduction Laboratory, Faculty of Agriculture, Mataram University. The method used in this study was an experimental method using a completely randomized design with 4 treatments and 3 replications, namely : commercial feed (control/P1), 96% ethanol extract 1:3 (P2), 96% ethanol extract 1:4 (P3), and ), 96% ethanol extract 1:5 (P4). Extraction was carried out by macerating K. alvarezii seaweed flour for 30 hours, then filtering and evaporating at 40 oC until an extract was produced in liquid form. The extract is mixed with feed at a rate of 2 g/kg feed. Before being given to feed, the extract is mixed first with 10 ml of distilled water. The tilapia seeds used measure 4 – 5 cm with a stocking density of 1 fish/liter. Fish rearing is carried out for 50 days, with a feeding frequency of 5% of the total weight of the fish and done 3 times a day. The test parameters are absolute weight, absolute length, specific growth rate (SGR), feed conversion (FCR), feed utilization efficiency, survival (SR) and water quality, which includes temperature, pH and DO. Data were analyzed using ANOVA and Duncan test at significant level of 0.05. The research results showed that the addition of K. alvarezii ethanol extract to tilapia feed can influence growth, feed utilization efficiency, feed convention rate (FCR), and survival rate (SR) of tilapia. The addition of K. alvarezii ethanol extract 1:5 to the feed showed the best results because it could increase the growth and utilization of tilapia feed with a survival rate of tilapia of 83%.

Lamtoro leaves (Leucaena leucocephala) are used as feed ingredients because they contain a lot of protein but are hampered by the high fiber content but can be reduced by fermentation to cover the smell of lamtoro leaves which fish do not like. This research aims to examine the effect of fermenting lamtoro leaves into artificial feed for sangkuriang catfish (C.gariepinus) on the growth and survival of sangkuriang catfish (Clarias gariepinus). This research used 120 Sangkuriang catfish with ± 3 grams and a length of ± 5-6 cm. This research method uses a quantitative and experimental approach using a Completely Randomized Design (CRD) consisting of four and three replications consisting of control, 10% lamtoro leaf fermentation, 15% lamtoro leaf fermentation, and 20% lamtoro leaf fermentation. The research observation parameters were absolute weight, absolute length, feed conversion, specific growth rate, and survival of sangkuriang catfish (Clarias gariepinus). The results showed that treatment with the addition of fermented lamtoro leaves had no significant effect (P>0.05) on the survival and growth of sangkuriang catfish. The conclusion from this research is that fermentation of lamtoro leaves has no significant effect on the growth and survival of sangkuriang catfish (Clarias gariepinus).
