Background
Metachronous second primary lung cancer (MSPLC) is not that rare but is seldom studied.

Objective
We aim to compare real-world survival outcomes between different surgery strategies and radiotherapy for MSPLC.

Methods
This retrospective study analyzed data collected from patients with MSPLC between 1988 and 2012 in the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) analyses and machine learning were performed to compare variables between patients with MSPLC. Survival curves were plotted using the Kaplan-Meier method and were compared using log-rank tests.

Results
A total of 2451 MSPLC patients were categorized into the following treatment groups: 864 (35.3%) received radiotherapy, 759 (31%) underwent surgery, 89 (3.6%) had surgery plus radiotherapy, and 739 (30.2%) had neither treatment. After PSM, 470 pairs each for radiotherapy and surgery were generated. The surgery group had significantly better survival than the radiotherapy group (P<.001) and the untreated group (563 pairs; P<.001). Further analysis revealed that both wedge resection (85 pairs; P=.004) and lobectomy (71 pairs; P=.002) outperformed radiotherapy in overall survival for MSPLC patients. Machine learning models (extreme gradient boosting, random forest classifier, adaptive boosting) demonstrated high predictive performance based on area under the curve (AUC) values. Least absolute shrinkage and selection operator (LASSO) regression analysis identified 9 significant variables impacting cancer-specific survival, emphasizing surgery’s consistent influence across 1 year to 10 years. These variables encompassed age at diagnosis, sex, year of diagnosis, radiotherapy of initial primary lung cancer (IPLC), primary site, histology, surgery, chemotherapy, and radiotherapy of MPSLC. Competing risk analysis highlighted lower mortality for female MPSLC patients (hazard ratio [HR]=0.79, 95% CI 0.71-0.87) and recent IPLC diagnoses (HR=0.79, 95% CI 0.73-0.85), while radiotherapy for IPLC increased mortality (HR=1.31, 95% CI 1.16-1.50). Surgery alone had the lowest cancer-specific mortality (HR=0.83, 95% CI 0.81-0.85), with sublevel resection having the lowest mortality rate among the surgical approaches (HR=0.26, 95% CI 0.21-0.31). The findings provide valuable insights into the factors that influence cumulative cancer-specific mortality.

Conclusions
Surgical resections such as wedge resection and lobectomy confer better survival than radiation therapy for MSPLC, but radiation can be a valid alternative for the treatment of MSPLC.

Abstract

Background
National suicide prevention strategies are general population-based approaches to prevent suicide by promoting help-seeking behaviors and implementing interventions. Crisis helplines are one of the suicide prevention resources available for public use, where individuals experiencing a crisis can talk to a trained volunteer. Samaritans UK operates on a national scale, with a number of branches located within each of the United Kingdom’s 4 countries or regions.

Objectives
The aim of this study was to identify any differences in call duration across the helpline service in order to determine whether service varied interregionally and intraregionally and to determine the impact of calls answered in the same region as the caller, compared with calls answered in a different region on the duration of calls made from landlines to Samaritans UK.

Methods
Calls may be routed by Samaritans, wherein the telephony system sends the call to the next available volunteer, irrespective of location; therefore, individuals may be routed to a branch within the same region as the caller’s current region (intraregional calls) or routed to a branch that is in a different region from that of the caller’s current region (interregional calls). The origin of calls by region was identified using the landline prefix of the anonymized caller identifier, along with the region of the destination branch (as branch details are recorded in the call details record). First, a Levene’s test of homogeneity of variance was carried out for each condition, that is, England calls and Scotland calls. Thereafter, for each condition, a one-way ANOVA or one-way analysis of means was carried out to evaluate any significant differences in call duration.

Results
ANOVA results showed that there are significant differences in call durations between intraregional calls and interregional calls (P<.001). Across all conditions within this study, callers stayed on the phone for a shorter period of time when routed to a branch that is within the same region as the call origin than if they were put through to a branch within a different region than the call origin.

Conclusions
Statistical analyses showed that there were significant differences between interregional and intraregional calls. On average, callers to crisis helplines stayed on the phone for a shorter period of time if they were routed to a branch within the same region in which the call originated than if they were routed to a branch in a different region of origin. The findings from this study have practical applications, which may allow crisis helplines to manage their resources more effectively and improve caller satisfaction with the service.

Background. Recently, to assess the physiological cardia in esophageal achalasia (EA), the method of endoscopic ultrasonography (EUS) has been used, which combines the capabilities of two studies, endoscopic and ultrasound, in addition to traditional diagnostic methods, radiography and endoscopy, and allows detecting structural changes in the esophageal wall and lower esophageal sphincter (LES). Objective: to determine the role of endoscopic ultrasonography in assessing the state of phy­siological cardia in esophageal achalasia. Materials and methods. In the Department of Digestive Surgery of the SI “Institute of Gastroenterology of the National Academy of Medical Sciences of Ukraine” in 2023–2024, according to the objectives of the study, 15 patients with EA and 20 practically healthy individuals (control group) were examined. All patients underwent X-ray and endoscopic examination of the oesophagus, stomach, duodenum, and EUS. Results. Videoesophagogastroduodenoscopy revealed changes characteristic of EA: dilation of the esophageal diameter (100.0 %), stagnant contents in the esophageal lumen (66.7 %), resistance to the passage of an endoscope through LES (86.7 %). X-ray revealed EA stage I in 13.3 % of cases by peristalsis and esophageal diameter, stage II — in 33.3 %, stage III — in 46.7 %, and stage IV — in 6.7 % of cases. When performing EUS, the esophageal hiatus was 19.29 mm (normal 23–36 mm); the eso­phageal wall thickness in the middle third was 6.76 mm (normal < 3 mm); the LES wall thickness was 6.02 mm (normal < 5 mm). To detect fibrotic changes in the esophageal and the LES wall, compression elastography was used. This method helped reveal a significant thickening of the internal circular muscle of the LES from 2.5 to 4.5 mm in 46.6 % of cases, and in 26.6 %, with EA stage III and IV, fibrotic changes were detected in the lower third of the esophageal wall. Conclusions. It has been found that EUS in EA answers questions that are not answered by traditional research methods, namely, it makes it possible to assess a number of parameters (thickness of the walls of the LES and the lower third of the esophagus, diameter of the esophageal hiatus) and identify structural changes (the presence of fibrosis), which significantly affects the choice of a method for a surgical correction of physiological cardia in EA.

Dalam ilmu fiqih, terdapat beberapa hal tentang mengebumikan jenazah sebagaimana apa yang telah ditetapkan dalam ajaran islam bahwa hukum mengebumikan jenazah adalah farḍu kifayah bagi orang-orang yang masih hidup dan memeluk agama Islam. Dari sekian banyak aturan dalam mengebumikan jenazah salah satu diantaranya ialah dengan menghadapkan posisi kuburan jenazah ke qiblat dan sekarang ini masih banyak masyarakat yang mengaggap sepele masalah penentuan arah qiblat khususnya arah qiblat kuburan Pernyataan tersebut bisa saja terjadi karena adanya anggapan masyarakat bahwa menghadapkan mayit ke arah qiblat dalam kuburan hanya anjuran saja, bukan kewajiban. Dari permasalahan tersebut menyebabkan banyak bangunan mesjid dan pemakaman tidak menghadap ke arah qiblat yang sebenarnya, bahkan dari kalangan masyarakat tersebut banyak menganggap arah barat adalah arah qiblat tapi kenyataannnya tidak seperti itu. Proses penentuan arah qiblat pada pemakan sebagian besar hanya ditentukan oleh imam masjid atau dengan mengikuti arah qiblat kuburan-kuburan yang terdahulu, mereka menganggap perpindahan matahari dari timur ke barat adalah arah qiblat, oleh sebab itu dalam penelitian ini penulis ingin melakukan pengukuran ulang terhadap qiblat kuburan dipemakamakan Desa Waetuoe Kabupaten Pinrang dengan menggunakan Qiblat Tracker dan Perhitungan manual berdasarkan lintang dan bujur tempat.Kata Kunci : Akurasi, Arah Qiblat, Kuburan, Qiblat Tracker.

Arah kiblat identik dengan pelaksanaan ibadah, baik ketika hendak melaksanakan Salat dan menguburkan atau memakamkan jenazah. Seseorang bisa dikatakan menghadap ke arah kiblat jika seluruh anggota tubuhnya menghadap ke arah Ka’bah yang menjadi patokan umat Islam dalam beribadah. Perkara saat ini bahwa ternyata di Desa Batulappa Kecamatan Patimpeng Kabuapten Bone penggali kubur hanya mengikuti posisi kuburan yang sudah ada sebelumnya dan mereka berpatokan pad metode perkiraan dengan melihat posisi terbenamnya matahari dari arah Timurk ke Barat maka itulah arah kiblat dan kuburan yang ada di Desa tersebut posisinya tidak beraturan. Hal ini terjadi kurangnya pemahaman masyarakat yang mengetahui tentang penentuan arah kiblat kuburan yang sesungguhnya. Oleh karena itu, peneliti akan terjung langsung ke lapangan untuk mengecek arah kiblat arah kiblat kuburan di Desa Batulappa Kecamatan Patimpeng Kabuapaten Bone dengan menggunanakan tongkat istiwa’, busur kiblat (sebagai alat bantu) dan perhitungam manuals berdasarkan pada lintang dan bujur suatu daerah.
Berdasarkan metode pengukuran yang dilakukan oleh peneliti dalam menentukan arah kiblat secara lanngsung dilapangan dengan menggunakan alat seperti tongkat istiwa’, bususr kiblat dan metode hisab arah kiblat pada ketiga tempat pemakaman yaitu Kuburan Kallecce, Kuburan Bulu Kacce, dan Kuburan Bulu Bilalalng. Hasil yang ditemukan oleh peneliti pada tiga titik lokasi pada pemakaman tersebut ialah di kuburan Kallecce di temukan kemelecenggan 2º-22º, di kuburan Bulu Kacce ditemukan Kemelencengan 3º-7º, sedangkan fakta kemelencengan yang ditemukan di kuburan Bulu Bilalang 7º-11º.

Published: June 2024

ABSTRACT
Eddy current array (ECA) technology is increasingly being used in the aerospace industry for non-destructive testing of aircraft components. This study evaluates the performance of ECA in detecting defects in aircraft components, focusing on its effectiveness, reliability, and sensitivity. The study evaluates the effectiveness of ECA technology in eddy current defectoscopy by introducing a dimensionless efficiency coefficient, then seeks to validate this coefficient through experimental testing of aircraft component materials with artificially induced defects of various sizes, types, and orientations to simulate real-world scenarios. ECA’s sensitivity in detecting small and subsurface defects is analyzed, along with precise defect sizing and positional information. Reliability and repeatability are investigated through repeated measurements. Furthermore, the article analyses the impact of various factors on the performance of ECA, including surface conditions, probe configurations, and inspection parameters. Comparative analysis is performed to assess the advantages and limitations of ECA in comparison to other conventional inspection methods. The findings of this study will contribute to a better understanding of the capabilities and limitations of ECA in detecting aircraft component defects. The results will aid in optimizing inspection strategies, enhancing the reliability of defect detection, and improving the overall maintenance practices in the aerospace industry.

Published: June 2024

ABSTRACT
This paper analyzes approaches to developing models for the technical exploitation (TE) of aircraft within operational management framework. The operational management contour of the TE of the airline’s AC fleet is considered as a TE process consisting of a sequence of flight routes, which, in turn, comprise a sequence of flights between airports in the airline network during the calendar interval when the aircraft are in this contour. We present a model that evaluates the capacity for aircraft recovery at the network airports of a hypothetical airline (dubbed “RAF”) if the need so arises, utilizing the probabilistic and temporal characteristics of the airports used for aircraft recovery.
