Authors: Garduño Alfonso
Published: June 2023

Dentro de la parafernalia militar mesoamericana, el uso de diferentes géneros y tipos de armas ha permitido estudiar las distintas dinámicas de enfrentamiento que se debieron haber llevado a cabo entre grupos antagónicos a lo largo de las diferentes etapas históricas de Mesoamérica. No obstante, a través del arte se puede apreciar que fue en el Clásico (100- 600 d. C.) donde surgen varias formas de armas entre las que se incluyen útiles de proyección, corte, penetración y contundencia, de estas últimas son las mazas las que han llamado la atención por su diversidad y morfología.

Published: June 2023

Renal angiomyolipoma is an uncommon, benign-mixed mesenchymal tumor consisting of thick-walled blood vessels, smooth muscles, and mature adipose tissues. Twenty percent of these tumors are associated with tuberous sclerosis. Wunderlich syndrome (WS), an acute nontraumatic spontaneous perirenal hemorrhage, can be a presentation of large angiomyolipoma. This study evaluated the presentation, management, and complications of renal angiomyolipoma with WS in eight patients who presented to the emergency department between January 2019 and December 2021. The presenting symptoms included flank pain, palpable mass, hematuria, and bleeding in the perinephric space on computerized tomography. Demographic data, symptoms at presentation, comorbidities, hemodynamic parameters, the association with tuberous sclerosis, transfusion requirements, need for angioembolization, surgical management, Clavien–Dindo complication, duration of hospital stay, and 30-day readmission rates were evaluated. The mean age of presentation was 38 years. Of the eight patients, five (62.5%) were females and 3(37.5%) were males. Two (25%) patients had tuberous sclerosis with angiomyolipoma, and three (37.5%) patients presented with hypotension. The mean packed cell transfusion was three units, and the mean tumor size was 7.85 cm (3.5–25 cm). Three of them (37.5%) required emergency angioembolization to prevent exsanguination. Embolization was unsuccessful in one patient (33%) who underwent emergency open partial nephrectomy, and one (33%) patient developed post-embolization syndrome. A total of six patients underwent elective surgery—four underwent partial nephrectomy (laparoscopic - 1, robotic - 1, open - 2) and two underwent open nephrectomy. Three patients encountered Clavien–Dindo complications (Grade 1, n = 2 and IIIA, n = 2). WS is a rare, life-threatening complication in patients with large angiomyolipoma. Judicious optimization, angioembolization, and prompt surgical intervention will help deliver better outcomes.

The tensile strength, initial fracture energy, and total fracture energy are the three parameters of interest in defining such softening response. Among them, the fracture energy is usually regarded in any analytical program that attempts to model reinforced concrete (RC) structures' behavior. The brittleness and fracture characteristics of lightweight concrete (LWC) produced from 19 mm maximum size natural pumice stone aggregate were investigated via testing notched beam specimens under three-point bending test. Fracture parameters were analyzed and explained using the size effect method (SEM) and the work of fracture method (WFM), and the results were compared to those found in the published literature. The results show mean total fracture energy (GF) of 145.65 N/m and a mean characteristic length (Lch) of 590.34 mm. Later, by correlating the result obtained via this method to the SEM approach, the initial fracture energy (Gf) was determined with a mean value of 58.26 N/m and the fracture toughness (KIC) was found to be 38.47 MPa.mm0.5. Lightweight concrete was found to be more ductile and need more energy to propagate fracture across the specimen, as shown by a comparison of current data to that acquired from literature.

Published: June 2023

BACKGROUND: Cognitive disorders are a relevant problem in an aging population. Research shows a wide range of data on the prevalence of cognitive disorders in the general population. Thus, more studies on the prevalence of cognitive disorders and assessment of the risks of their development are necessary, which will determine the burden on the regional healthcare system.
AIM: To examine the prevalence of cognitive impairment in an outpatient multidisciplinary clinic setting and determine the risk ratios for cognitive deficits in different age groups.
MATERIALS AND METHODS: The Montreal Cognitive Assessment Scale was used in the screening of people aged 4590 years.
RESULTS: Cognitive dysfunction was noted in 20.0% of patients in the group aged 4559 years, 33.1% in the group aged 6074 years, and 79.6% in the group aged 7590 years. The average results on the assessment of cognitive functions of persons aged 4559 (27.10.3) and 6074 (26.20.2) years corresponded to the norm, and the value in persons aged 7590 (23.60.3) years was below the norm. In groups aged 6074 and 7590 years, the prevalence of cognitive dysfunction was comparable between men and women. Cognitive impairments in men aged 4559 years were recorded 2.5 times more often than that in women. The risk of cognitive disorders in the second group (aged 6074 years) relative to that in the first group (aged 4559 years) is insignificant (relative risk [RR], 1.21). In the third group (aged 7590 years), the probability of cognitive disorders is significantly higher than that in the second group (RR=2.40) and nearly five times higher than that in the first group (RR=4.86).
CONCLUSION: Sex- and age-stratified screening indicators for assessing cognitive functions and the RRs of developing cognitive disorders in older age groups make it possible to plan for diagnostic, therapeutic, and preventive measures in mental health.

Authors: PÜR İlyas
Published: June 2023

Sağlık sektöründe yer alan hemşireler, hem ekip arkadaşları ile hem de hastalarla sıkı bir irtibat halindedirler. Bu da onların tükenmişlik düzeyini yükseltmektedir. Bu tehlike Covid 19 salgını ile birlikte daha da artmıştır. Çünkü bulaşıcılık, artan iş yükü, ölüm tehdidi, sürecin belirsizliği, hastalarla uzun süre beraber olma ve aileden ayrı kalma gibi sebepler onların kaygı ve tükenmişlik düzeyini yükseltmektedir. Hemşireler, tüm bu faktörlerle mücadele ederken onların bu durumlardan başa çıkmalarını destekleyecek hususlardan da beslenmektedirler. Bu anlamda, onların psikolojik dayanıklılıklarını besleyen maneviyat eğilimlerini incelemek önem kazanmaktadır. Bu çalışmada, tükenmişliğin yüksek görüldüğü sağlıkta çalışan gruplarından biri olan hemşirelerde tükenmişlik ve maneviyat düzeyleri arasındaki ilişkinin araştırılması amaçlanmıştır. Ayrıca maneviyat ile tükenmişlik sendromu ilişkisinde psikolojik dayanıklılığın ara bulucu rolüne değinmek de araştırmanın amaçları arasında yer almaktadır. Araştırma, ilişkisel tarama modeline dayalı olarak oluşturulmuştur. Çalışmaya, sağlık kurumlarında görev yapan 216 hemşire katılmıştır. Katılımcılara Kişisel Bilgi Formu, Maslach Tükenmişlik Ölçeği ve Maneviyat Ölçeği uygulanmıştır. Katılımcıların veri analizleri SPSS Statistics 20 ve paket yazılımında gerçekleştirilmiştir.

Authors: Chaurasia Amrita , Jain Kajal , Ojha Vandana , Sachan Nidhi , Singh Vidhi
Published: June 2023

Background: Aim of the study was to compare the suture techniques using interrupted mattress and continuous subcuticular and stapler in terms of wound closure time; pain in stitch line on post-operative day 3, 5 and 7 and patient satisfaction.
Methods: All patients fulfilling the inclusion criteria, were divided into 3 categories (interrupted mattress, subcuticular and staples) by random selection. Assessment parameters being skin closure time; induration and discharge on day 4 and 8; pain score using visual analogue scale on day 3, day 5 and 7; wound gaping and Patient satisfaction in terms of cosmesis using Likert’s scale after 4-6 weeks.
Results: The skin closure time in mattress, subcuticular sutures and staples are found to be 8.891±1.343; 11.390±1.438 and 1.518±0.502 respectively. Pain on day 3, 5 and 7 were: severe pain was maximum seen in staples group (n=21) as compared to 7 patients in subcuticular group and 6 in mattress group. Wound complications were seen least in mattress group. One patient (1.20%) had wound gaping in mattress group, 3 (3.65%) of the patients in subcuticular group and 5 (6.17%) in staples group had wound gaping. Patient dissatisfaction rate was higher in staples group (8.64%) as compared to 6.09% patient in subcuticular group and 4.8% in mattress group.
Conclusions: The mattress suturing technique has least wound related complications and most patients satisfaction. Staples are quick in application and subcuticular technique gives a good scar, but is associated with similar complications as staples.
A study of port site infections in patients underwent laparoscopic cholecystectomy and its prevention and management
Authors: Biswas Arnab , Nandy Sagnik , Mondal Debashis
Published: June 2023

Background: Rapid growths in health care technology have given the surgeon the power of not only treating diseases surgically but also limiting surgical invasiveness.
Methods: It is an institution based non-randomized, prospective, analytical study at Burdwan Medical College and Hospital.
Results: As far as our study is concerned all the hospitals from where patients came were using “activated di-aldehyde” solution for sterilization of laparoscopic instruments; it may be a strong possibility that there might have been a growth of atypical mycobacteria in this solution, as four out of the five cases reported here found to be seropositive for tuberculosis.
Conclusions: Port site infection (PSI), although infrequent, can be a frustrating complication in minimal access surgery (MAS), both for the patient as well as the operating surgeon. After the surgery, all the instruments should be dismantled completely. Cleaning and washing the instruments should be done under running water.

Even in the advanced era of today, maternal morbidity and mortality are quite high; however, most pregnancy-related complications can be successfully prevented by early diagnosis and timely management. The primary care setting is of utmost importance in this regard, as it is the first line of contact between patients and physicians, and regular antenatal care services are provided by most of primary care settings. Ectopic pregnancy is one of the most prevalent pregnancy disorders and is further associated with high-risk complications and mortality. The clinical manifestations may mimic non-ectopic pregnancy conditions, making it difficult to develop diagnostic standards. However, ultrasonography and human chorionic gonadotropin (β-hCG) levels can ensure early diagnosis. Conservative treatment is pursued since surgical management is linked to multiple significant side effects. In most situations, pharmacotherapy using methotrexate in a single- or multi-dose regimen is the preferred course of treatment. Performing ultrasonography as soon as a pregnancy is confirmed to determine the location of the pregnancy, monitoring β-hCG levels, and ensuring prompt referral in the event of a possible ectopic pregnancy that cannot be treated conservatively are all important ways that primary care settings can play a significant role in early diagnosis and prompt management. Additionally, obstetric ultrasonography training for family physicians can help in the early detection of ectopic pregnancy, which can lead to favourable results. The purpose of this research is to review the available information about strategies to improve the diagnosis and management of ectopic pregnancy in primary care.
