Authors: Çaparlar CÖ , Altinsoy S , Akelma FK , Özhan MÖ , Ergil J 
Published: September 2022

Background:
Ultrasound-guided truncal nerve blocks are increasingly used for postoperative pain relief after abdominal surgery.

Aim:
The aim of this prospective and randomized study was to compare posterior transversus abdominis plane block (pTAPB) with posterior quadratus lumborum block (pQLB) for postoperative analgesic efficacy in patients undergoing unilateral inguinal hernia surgery under general anesthesia (GA).

Patients and Methods:
A total of 90 adult patients were randomized into 3 groups: group pTAPB (n = 30), group pQLB (n = 30), and group Control (n = 30). The patients in groups pQLB and pTAPB received a unilateral block using 20 ml of 0.25% bupivacaine after the induction of GA. Intravenous (IV) tramadol patient control group analgesia (PCA) and paracetamol were used in the postoperative period as a part of the multimodal analgesic regimen in both groups. Postoperative pain was assessed using a visual analog scale (VAS) during postoperative 24 h. Dexketoprofene was used as a rescue analgesic when VAS is >3. The primary outcome measure was mean pain scores. Secondary outcome measures were consumption of rescue analgesics and the amount of tramadol delivered by PCA. P <0.05 was considered statistically significant.

Results:
Mean VAS scores were significantly lower in the group pQLB than group pTAPB and group Control at all-time points (pQLB < pTAPB < Control; P < 0.001). Rescue analgesic was not required in group QLB. Rescue analgesic consumption, the number of bolus demand on PCA, and total PCA dose were highest in group Control and lowest in the pQLB group (Control > pTAPB > pQLB; P < 0.001).

Conclusion:
It is concluded that both pQLB and pTAPB provided effective pain relief after unilateral inguinal hernia surgery. pQLB was superior to pTAPB due to lower pain scores and analgesic consumption.

Published: September 2022

Background:
Caffeine consumption during pregnancy has effect on newborn anthropometry therefore the amount of maternal caffeine consumption is important.

Aim:
This study aims to determine caffeine consumption during pregnancy and related factors.

Subjects and Methods:
This study was carried out in a maternity hospital located in Eastern Turkey from September 2018 to June 2019 with 300 healthy primiparous women and babies. Data were collected by the researchers with a socio-demographic questionnaire and caffeine consumption frequency semi-quantitative questionnaire using the face-to-face interview technique. Postpartum weight and height of the women and length, weight, and head circumference of the newborns were measured. Evaluation of the data was carried out with Kruskal–Wallis and Mann–Whitney U test and binary logistic regression analysis was used for relationship analysis.

Results:
The mean daily caffeine intake of the pregnant women was determined as 344.9 ± 181.4 mg/day and 4.9 ± 2.6 mg/kg/day. The babies' mean birth weight was 2943.1 ± 407.4 g, mean length was 50.1 ± 2.2 cm, and mean head circumference was 32.3 ± 1.6 cm. A statistically significant negative correlation was found between caffeine consumption of pregnant women and newborn birth weight and length (P = 0.049; P = 0.007, respectively). After age, economic and educational status, and pre- and post-pregnancy BMI were corrected according to weight increase during pregnancy and after binary logistic regression analysis was performed, it was determined that caffeine consumption did not have an effect on low birth weight (Total caffeine consumption (mg/day), P = 0.669 OR = 1.00, 95% Cl = 0.997-1.002; caffeine consumption (mg/kg), P = 0.549 OR = 0.956, 95% Cl = 0.824-1.109).

Conclusion:
Caffeine consumption of pregnant women is higher than the recommended levels. Therefore, pregnant women should be informed about caffeine sources and consumption amounts.
Clinicopathological Profile of Myxoid Soft Tissue Tumors- A Retrospective Study in a Tertiary Care Hospital in South India
Authors: Sigamani Karthik , Ponnuswamy Karkuzhali 
Published: September 2022

Background:
Myxoid soft tissue tumors are rare and diagnostically challenging group of tumors with varied biological behavior ranging from benign, locally aggressive to distantly metastasizing malignant tumors.

Aims:
The objectives of the study are to identify the relative frequency and distribution of myxoid soft tissue tumors among patients in a tertiary care hospital and to study the clinicopathological features of these tumors. This was a retrospective cross-sectional study conducted in the department of pathology of a tertiary care hospital from January 2008 to December 2013.

Materials and Methods:
Clinical and pathological details of all the 80 myxoid soft tissue tumors reported during the study period were retrieved from the records of department of pathology. Corresponding Hematoxylin & Eosin (H & E) slides were reviewed, and Immunohistochemistry (IHC) was carried out for confirmation. The relationship among various prognostic variables was analyzed in case of myxoid sarcomas.

Results:
Myxoid soft tissue tumors accounted for 3.7% among the soft tissue tumors with a predominance of malignant myxoid sarcomas (71.25%) in contrast to the overall picture of sarcomas. Myxoid neurofibroma (34.78%) was the most common benign tumor, while myxofibrosarcoma (33.33%) was the frequent myxoid sarcoma. A statistically significant correlation was seen between tumor size and depth (P-value: 0.038) and also between presence of vascular invasion and histological grade (P-value: 0.012) of sarcomas.

Conclusion:
Light microscopic morphology, supplemented by ancillary techniques like IHC, remains the cornerstone for diagnosis of myxoid soft tissue tumors.

The Efficacy of Bismuth Quadruple Therapy, Sequential Therapy, and Hybrid Therapy as a First-Line Regimen for Helicobacter pylori Infection Compared with Standard Triple Therapy
Authors: Koroglu M , Ayvaz MA , Ozturk MA 
Published: September 2022

Background and Aim:
To compare the effectiveness of first-line Helicobacter pylori eradication treatments as standard triple therapy (sTT), bismuth-containing quadruple therapy (BQT), sequential therapy (ST), and hybrid therapy (HT).

Patients and Methods:
303 patients treated between July 2018 and June 2021 were studied. In this study, 76 patients in the sTT group, 78 patients in the BQT group, 75 patients in the ST group, and 74 patients in the HT group were randomly allocated. The diagnosis of H. pylori was made endoscopically. H. pylori stool antigen test was performed 4 weeks after finishing the treatment.

Results:
The mean age was 48.53 (13.48) in sTT, 49.04 (13.02) in BQT, 48.47 (14.54) in ST, and 47.45 (13.4) in HT. There was no significant age difference among the groups (P = 0.909). H. pylori eradication rate in intention-to-treat (ITT) analysis was 68.4% in sTT, 79.5% in BQT, 78.7% in ST, and 83.8% in HT. There was no significant difference between sTT, BQT, and ST regarding of eradication rate. The difference between HT and sTT was significant (P = 0.028). In the per-protocol (PP) analysis, the eradication rate was 74.3% in sTT, 88.6% in BQT, 86.8% in ST, and 92.5% in HT. There was a significant difference between sTT and BQT (P = 0.030) and sTT and HT (P = 0.004), whereas there was borderline significant difference between sTT and ST (P = 0.065).

Conclusion:
In terms of eradication, HT had the best rate, whereas the lowest rate was in the sTT treatment group. This study does not recommend using sTT because of the low eradication rates. This study recommends HT for overcoming antibiotic resistance and better results.

Authors: de Barros Guilherme Feltrin , Passos Juliana Portela , Coblentz Jacqueline , Burnier Miguel N 
Published: September 2022

Objective:
This study aimed to examine the frequency of atypical features in conjunctival nevi in pediatric patients referred to the McGill University Health Center-McGill University Ocular Pathology and Translational Research Laboratory and to emphasize the importance of histopathological analysis to rule out malignant lesions, such as melanoma.

Methods:
Forty-four pediatric patients younger than 20 years of age previously diagnosed with melanocytic lesions of the conjunctiva were included in this study, and the database was analyzed for a 10-year period (2006–2015). Clinical information such as age, gender, location, type, size, and agreement between clinical and pathological diagnosis was also recorded and presented as means and percentages.

Results:
The mean age was 11.3 years, of which only 9.1% were older than 18 years. Gender predilection was found toward males (52.3%). An agreement was noted between clinical and pathological diagnosis in 77.2% of cases; only 22.72% showed atypia upon histopathological examination. The most common pathological diagnosis was compound nevus with different characteristics. The atypical lesions included conjunctival melanoma, junctional nevi with atypia, compound nevi with atypia, and cystic compound nevi. Moreover, 70% of the patients with atypical lesions were males and 60% of the specimens were from the right eye.

Conclusion:
An impressive number of 30% of all patients had some type of atypia after histopathological analysis. Therefore, based on these results, it is of extreme importance that all melanocytic lesions are sent for histopathological analysis, so an accurate diagnosis can be established.
A study comparing either using intravenous propofol or topical lidocaine over the larynx as adjuncts to inhalational induction of anesthesia for facilitating nasotracheal intubation for pediatric patients undergoing tonsillectomy surgery
Authors: Ayoub Sabah Naguib Barsoom 
Published: September 2022

Background
Nasotracheal intubation in tonsillectomy surgery is used to facilitate surgical exposure. Intubation without muscle relaxant is commonly practiced for pediatric patients in ambulatory surgeries. Using adjuncts to inhalational induction makes more suitable conditions for intubation with hemodynamic stability and less laryngeal morbidities. In this study, lidocaine, 1% was used topically on vocal cords to facilitate nasotracheal intubation in comparison with intravenous propofol after inhalational induction using muscle relaxant only as a rescue medication in case of failure.

Patients and methods
A randomized controlled study was conducted on 96 patients aged 3–7 years and with American Society of Anesthesiologists physical status I and II scheduled for elective tonsillectomy. Patients were divided randomly into two equal groups, each consisting of 48 patients. Group P patients received inhalational induction using sevoflurane followed by propofol 2 mg/kg. Group L received inhalational induction by sevoflurane followed by topical lidocaine 1% on glottic and supraglottic areas. The intubation conditions, hemodynamic parameters (heart rate, mean blood pressure, and oxygen saturation), respiratory depression, sedation score, and incidence of laryngospasm after recovery were recorded and statistically analyzed.

Results
The intubation score was statistically significant with a high difference between the two groups. The score mean values were less than 10 with more success of the intubation in the lidocaine group. The success rate of intubation without the use of short-time-acting muscle relaxant was higher in the lidocaine group (88.89%) as compared with the propofol group (79.2%). Hemodynamic stability after intubation in the lidocaine group, was statistically significant. The incidence of postoperative laryngospasm was statistically nonsignificant, but the incidence rate was higher in the propofol group.

Conclusion
Using lidocaine 1% topically on the larynx can achieve an acceptable condition of the intubation without muscle relaxant in most of the cases, with hemodynamic stability and decreasing incidence of postoperative laryngospasm.

Authors: Ali Rania M. , El Deen Ewis Hasan Bahaa , El Shaer Ahmed N. , Shabaan Sherif E. , El Ghazaly Ahmed E. , El Derh Maha S. 
Published: September 2022

Objective
To assess the clinical value of daily serum procalcitonin (PCT) measurements for guiding the initiation of antibiotic treatment in critically ill patients with systemic inflammation response syndrome (SIRS) without evident infection and compare it with empiric antibiotic administration on ICU admission.

Patients and methods
This randomized double-blinded prospective controlled clinical study was conducted on 72 patients with SIRS without evident sepsis admitted to the ICU of the Obstetrics and Gynecology Hospital in Ain Shams University Hospitals from October 2018 to December 2020.

Results
PCT level was elevated above the cutoff value of 2 ng/ml in 15 patients in the PCT-guided antibiotic therapy group and 11 patients in the empiric antibiotic therapy group. PCT elevation above 2 ng/ml in the surgical subset was more significant than in the medical subset in both groups. The Sequential Organ Failure Assessment score and the length of ICU stay were not statistically significant different between the two groups.

Conclusions
Postponing antibiotic therapy in patients admitted to ICU with suspected noninfectious SIRS until PCT is higher than 2 ng/ml is safe, especially in medical ICU.

Authors: Mitra Sukanya , Ahuja Vanita , Garg Sudhir 
Published: September 2022

Background and objective
The preventive perioperative use of etoricoxib versus ibuprofen in patients undergoing either elective total hip arthroplasty or total knee arthroplasty (THA/TKA) surgeries has not been evaluated.

Patients and methods
This randomized open-label trial was conducted in 60 patients of the American Society of Anesthesiologists physical status I/II, of either sex, 18–70 years, undergoing elective unilateral THA/TKA. Group ibuprofen (n=30) received ibuprofen 400 mg per oral 1 h before surgery and then every 6 h for 48 h postoperatively. Group etoricoxib (n=30) received etoricoxib 120 mg of per oral 1 h before surgery and then at 24 and 48 h postoperatively. Both groups received combined spinal–epidural anesthesia intraoperatively and patient-controlled epidural analgesia postoperatively for 48 h. The primary outcome of the study was pain assessment using visual analog scale (VAS). The number of epidural bolus, rescue tramadol consumption, hemodynamics, postoperative nausea and vomiting, and side effects in 48 h postoperatively were also recorded.

Results
The VAS at rest at 4 h was greater in group ibuprofen versus in group etoricoxib, P value of 0.023. The VAS on movement at 2 and 4 h was greater in group ibuprofen versus group etoricoxib, P value of 0.013, P value of 0.014, respectively. The mean±SD (range) blood loss was reported to be greater in group ibuprofen as compared with group etoricoxib, P value of 0.013. There were no side effects.

Conclusion
Preventive use of oral etoricoxib versus ibuprofen for 48 h postoperatively reported similar pain relief in patients receiving following elective THA/TKA surgeries.

Trial registration
The clinical trial was registered with Clinical Trial Registry India (CTRI/2011/07/001901).
Diabetes mellitus in association with hepatic encephalopathy in patients with hepatitis C virus cirrhosis
Authors: Hossam Hazem , Abd El-Khalik Ashraf , Khaled Hassan 
Published: September 2022

Background
There is growing evidence to support the concept that hepatitis C virus (HCV) infection is a risk factor for developing type 2 diabetes mellitus (T2DM) and that diabetes control could affect the prognosis of hepatic encephalopathy.

Objective
To study the relation between type of DM and HCV cirrhosis and to report any relationship between the outcome of hepatic encephalopathy and the glycemic control in the period before precipitation of encephalopathy.

Patients and methods
A total of 30 selected diabetic, HCV cirrhotic patients with age ranging from 43 and 70 years (mean, 55.87 years), admitted to the ICU for hepatic encephalopathy, were prospectively enrolled in this study. Cirrhosis was evaluated according to Child classification, whereas encephalopathy was evaluated according to West Haven criteria as well as Richmond agitation sedation score. Glycated hemoglobin was used to assess the glycemic control in the period before precipitation of encephalopathy.

Results
T2DM was more prevalent than type 1 in association with HCV (83.3% T2DM and 16.7% T1DM). Diabetes control plays no role in increasing the severity of cirrhosis (nonsignificant, with P & 0.249). The diabetic HCV cirrhotic patients admitted for hepatic encephalopathy had shorter ICU stay when DM was well-controlled medically in the period before precipitation of encephalopathy (P & 0.001). Moreover, the mortality was decreased markedly in association with diabetes control (P & 0.01).

Conclusion
HCV viremia had a higher risk of T2DM than T1DM. Diabetes control has no role in increasing the severity of HCV cirrhosis. In HCV cirrhotic diabetic patients, well- controlled DM could improve the ICU outcome (shorter ICU stay and less mortality) when admitted for hepatic encephalopathy.

Authors: Handayani Hanifah , Kholil Kholil , Widiowati Dewi 
Published: September 2022

Communication is something that is required in everyday life to express thoughts or ideas to invite others to act and produce desired changes, both in terms of individuals and organizations. Within organizations, communication has an impact on organizational performance. This study aims to determine the effective communication model of OHS in PT Armada Bangun Samudra (PTABS), a shipbuilding company. Data were collected from 185 respondents who were selected randomly from a pool of 344. Data analysis used Structural Equation Modeling (SEM). The results reveal that communication can be effective in an organization with multiple sub-organizations/sections if it is carried out in a hierarchical manner one level above or below. This study found that the leader’s communication skills had a significant effect on work discipline. Employee work discipline has a significant effect on the company’s OHS performance. To improve OHS performance, organizational leaders' communication skills and employee participation at all levels must be improved.
Narrating “Their War” and “Our War”
Authors: Springer Nina , Nygren Gunnar , Widholm Andreas , Orlova Dariya , Taradai Daria 
Published: September 2022

“Patriotic journalism,” a deviation from objectivity, has become an important paradigm and well-documented phenomenon in the analysis of conflict coverage. However, studies rarely focus on the link between journalists’ perceptions and narratives. We investigated how journalists from two countries, one involved in a conflict (Ukraine) and the other observing it from a distance (Sweden) relate to the objectivity norm in sourcing and narrating seven conflictive news cases in Ukraine (2017 to 2018). We found pragmatic commitment to objectivity in both countries, which was not always reflected in the content produced. For Swedish journalists, our results hint toward a value-based ally loyalty, which seems less stable than a tribe-based bond. In Ukraine, official Ukrainian perspectives were undisputedly disseminated; however, we did not find that they were generally positively laden, as one would expect for patriotic journalists. Trust in public institutions might be a deciding factor over the extent of patriotism.
The ion–ion recombination coefficient α: comparison of temperature- and pressure-dependent parameterisations for the troposphere and stratosphere
Authors: Zauner-Wieczorek Marcel , Curtius Joachim , Kürten Andreas 
Published: September 2022

Abstract. Many different atmospheric, physical, and chemical
processes are affected by ions. An important sink for atmospheric ions is
the reaction and mutual neutralisation of a positive and negative ion, also
called ion–ion recombination. While the value for the ion–ion recombination coefficient α is well-known for standard conditions (namely 1.7 × 10−6 cm3 s−1), it needs to be calculated for deviating temperature and pressure conditions, especially for applications at higher altitudes of the atmosphere. In this work, we review the history of theories and parameterisations of the ion–ion recombination coefficient, focussing on the temperature and pressure dependencies as well as the altitude range between 0 and 50 km. Commencing with theories based on J. J. Thomson's work, we describe important semi-empirical adjustments as well as
field, model, and laboratory data sets, followed by short reviews of binary
recombination theories, model simulations, and the application of
ion–aerosol theories to ion–ion recombination. We present a comparison
between theories, parameterisations, and field, model, and laboratory data sets to conclude favourable parameterisations. While many theories agree well with field data above an altitude of approximately 10 km, the nature of the recombination coefficient is still widely unknown between Earth's surface and an altitude of 10 km. According to the current state of knowledge, it appears reasonable to assume an almost constant value for the recombination coefficient for this region, while it is necessary to use values that are adjusted for pressure and temperature for altitudes above 10 km. Suitable parameterisations for different altitude ranges are presented and the need for future research, be it in the laboratory or by means of modelling, is identified.
