Plain concrete beam repair and strengthening are increasingly important in structural strengthening and retrofitting. This study examines the glass fibre-reinforced polymer (GFRP) sheets in plain concrete beams under flexural behaviour by using its patching sheets. Through the implementation of a symmetrical four-point static loading technique, a series of tests were conducted on plain concrete beams that had been externally joined with GFRP sheets. These beams were subjected to rigorous testing until they reached their ultimate failure point. The experimental test consists of casting nine plain concrete beams with identical specifications. Three beams are utilised as control beams; three are reinforced with GFRP sheets measuring 50 mm × 100 mm, and another three are reinforced with GFRP sheets measuring 100 mm × 200 mm. The flexural test is designed to determine the tensile strength of concrete under bending. Compared to the control beams, the specimens strengthened with GFRP sheets demonstrated a significantly enhanced ultimate load capacity. The beams with larger GFRP sheets exhibited a higher ultimate load of 14.84 kN, while those with smaller sheets showed an ultimate load of 8.54 kN, marking an appreciable improvement in performance. Moreover, the smaller area GFRP-reinforced beams failed at a 45% higher shear stress compared to those with a larger area GFRP, indicating a differential impact based on the size of the reinforcement used. This study highlights the effectiveness of GFRP sheets in enhancing the structural performance of plain concrete beams, providing crucial insights into the benefits of different sizes of reinforcement.

In recent years, there has been a noticeable rise in the need for wireless network connection in healthcare facilities. This is a result of the requirement for immediate access to patient data as well as the growing number of medical devices that are internet-connected. To guarantee dependable and secure communication as well as support for diverse healthcare applications and services, it is essential to choose the right wireless network type. However, the selection procedure can be difficult because it includes a number of variables that are frequently arbitrary and subjective. The difficulties of choosing the best wireless network type to be used in healthcare facilities are addressed in this research by the introduction of a new fuzzy model for multi-criteria decision-making (MCDM). The approach considers several evaluation factors, including patient cost, patient privacy, patient safety, and patient comfort and convenience. The model uses a fuzzy analytic hierarchy process (FAHP) to compute the weights of these criteria. In addition, the model uses fuzzy methods like fuzzy ARAS, fuzzy EDAS, and fuzzy TOPSIS to rank the different kinds of wireless networks according to their performance. It is clear from the results that the suggested model can effectively and dependably assess different alternatives. Additionally, it provides useful and practical advice on how to choose the right wireless network types for medical facilities. The best feature is that this approach is easily adaptable to other healthcare industry decision-making procedures.

Stroke is a potentially fatal illness that requires emergency care. There is a greater chance that the patient will recover and resume their regular life when they receive treatment and diagnosis as soon as feasible. Artificial Intelligence has the potential to significantly impact stroke diagnosis and facilitate prompt patient treatment for physicians. Machine learning can be utilized in stroke prediction by evaluating huge volumes of patient data and detecting patterns and risk variables that may contribute to the likelihood of a stroke. In this study, we explored a stacked ensemble model that uses four base models—Decision Tree, XGBoost, RandomForest, and ExtraTree classifiers to predict the stroke. We discovered that the accuracy of the stacked ensemble model was 96.35%, higher than that of the traditional machine-learning models, other ensemble models, and ANN model.

Background: The true incidence of pelvic organ prolapse (POP) using validated method of examination in a wider range of population of women needs evaluation in our setting. This study determined the prevalence of the different POP quantification (POPQ) stages of POP and correlated these stages with clinical symptoms alongside the determinants of POP among women in Ile-Ife, Nigeria.
Methods: This was a cross-sectional study of consecutive, consenting four hundred women (aged 22-74years) attending the gynaecology, general outpatient, family planning, and well-woman clinics at Obafemi Awolowo university teaching hospitals complex, Ile-Ife, Nigeria between January 2016 and December 2016. Relevant biodata was documented in a purpose designed and pre-tested questionnaire, and the international consultation on incontinence questionnaire vaginal symptoms (ICIQ-VS) was administered. Data were analysed using IBM SPSS version 20.0. The prevalence of the different POPQ stages was determined. Logistic regression analysis was then performed to identify the significant determinants.
Results: The study showed a prevalence of POPQ of 13% (stage 0), 85.3% (stage I), 1.3% (stage II) and 0.5% (stage III). Age, parity, menopausal status, chronic constipation, childbirth position, caesarean section and lifting of heavy objects were the identified significant determinants.
Conclusions: There is a significant correlation between POPQ stage and the symptom ‘feeling of lump in the vagina’. Chronic constipation and lifting of heavy objects are modifiable significant risk factors in our study population.

Authors: Shakeel Isha , Shabbir Ahmad , Yumn Laiba , Akhtar Mariyam , Khan Esha , Khan Ali Ahmad
Published: July 2024

Background: Reducing maternal mortality and morbidity requires an accurate diagnosis of ectopic pregnancy. The fallopian tube is the most frequent location for ectopic pregnancy.
 Methods: This study was based on a longitudinal analytical design conducted at tertiary care hospitals in Pakistan. Patients in the reproductive age range (20 to 32 years) who underwent clinical examination and investigations and were diagnosed with ectopic pregnancy were included in this study. The ultrasound results of all the patients were evaluated, and data was collected on the existence and positioning of an ectopic pregnancy.
Results: In the study, 198 women underwent TVS and TAS. At the time of diagnosis, the age range was 20-32 years old. Our study found that 2.5% of pregnancies resulted in an ectopic pregnancy. 20 women had symptomatic EP that was confirmed. For the initial TVUS, the sensitivity and specificity of ultrasonography were 88.5% and 96.5%, respectively, and with a second rescan, they were 93.1% and 95.7%.
Conclusions: Our study showed that an excellent method for identifying ectopic pregnancy is trans-abdominal ultrasonography. Regarding diagnostic accuracy metrics, however, it falls short of trans-vaginal ultrasound. To avoid missing any cases of ectopic pregnancy, early detection can significantly reduce morbidity and mortality. We should employ both ultrasonography modalities sequentially, with TAS being used first.

Authors: Negi Priyanka , Choudhary Anjali , Kaushik Srishti , Nimonkar Shweta
Published: July 2024

Background: Cerebro-placental ratio (CPR), measured by Ultrasound Doppler velocimetry in pregnancy, has gained much attention in recent years as an important tool in predicting perinatal outcomes. The study aimed to calculate the cerebro-placental ratio and correlateit with perinatal outcome in terms of intrapartum fetal heart variation, meconium staining of liquor, mode of delivery, Apgar score at birth, and NICU admissions.
Methods: It was hospital-based prospective cross-sectional study on 119 pregnant women with high-risk pregnancies. All women had doppler velocimetry ultrasound, and cerebro-placental ration was calculated. Perinatal outcome was noted in terms of FHR variability in labor, Meconium staining of liquor, Apgar score and need for NICU admission.
Results: Out of the total of 119 women, 88 women had CPR >1.08 and 31 women had CPR of <1.08. Meconium staining of liquor, low Apgar score, and NICU admission was mound in significantly more babies with low CPR.
Conclusions: CPR has a good prognostic value in predicting many adverse perinatal outcomes.

Authors: Raut Srushti Sunil , Babbar Kavita
Published: July 2024

Background: The objective of the study was to do diagnostic comparison of ultrasonography, hysteroscopy and histopathological examination in evaluation of abnormal uterine bleeding.
Methods: An observational prospective study is conducted amongst 219 married women between age of 25 years to 59 years with Abnormal uterine bleeding admitted for diagnostic hysteroscopy at Obstetrics and Gynecology Department, Apollo Hospital, Bilaspur, Chhattisgarh from November 2022 to October 2023. Statistical analysis was assessed by chi square test.
Results: Myoma is best diagnosed by Sonography. The exact size, shape, type of fibroid and location can be accurately diagnosed by USG. Endometrial hyperplasia, endometrial polyp, submucous fibroid, growth, septum, flimsy adhesions, focal lesions and intracavitary intrauterine lesions are best diagnosed by hysteroscopy. Endometrial carcinoma is best diagnosed by histopathology.
Conclusions: Hysteroscopy has important role in diagnosis of intrauterine and endocervical canal abnormalities. Addition of hysteroscopy with histopathological examination of endometrial and cervical biopsy sample along with transvaginal ultrasonography enhances the accuracy of diagnosis. Use of hysteroscopy, ultrasonography and histopathology were not competitive rather complementary for diagnosing patients with abnormal uterine bleeding. Diagnostic tools like ultrasonography, hysteroscopy and histopathology helps in accurate, early diagnosis of endometrial and cervical cancer which prevents further damage and further spread and metastasis of disease to adjacent tissues/ organs. Early diagnosis and cure increases life expectancy and decreases morbidity and mortality.

Authors: Marwah Sheeba , Agarwal Avinika , Saini Rashi , Balayan Ashwani
Published: July 2024

Caesarean scar ectopic pregnancy (CSEP) is an ectopic pregnancy located in the lower uterine segment. Although it is one of the rarest types of ectopic pregnancy, the worldwide increasing rate of caesarean sections has made it important for young gynaecologists to be aware of the challenges posed by CSEP and its successful management. Doppler ultrasounds play a major role in its diagnosis. Early diagnosis is the key to a good outcome as untimely delay can lead to life-threatening haemorrhage, uterine rupture and irreversible loss of fertility. We present a case series of 4 patients of caesarean scar site ectopic pregnancy who presented to the gynaecology emergency and were treated successfully with various modalities depending on their patient profile.

Authors: Ehigiegba Oduware E. , Nwogoh Benedict , Iweka Reuben O.
Published: July 2024

Severe anaemia in pregnancy is associated with high maternal and perinatal morbidity and mortality. The life-threatening complications associated with severe anaemia in pregnancy were averted in this case due to the astute management and multidisciplinary approach employed involving the hematologist, dietician, and obstetrician. We report a rare case of a 33-year-old pregnant woman with three living children who presented with severe anaemia, characterized by a hematocrit of 8% (haemoglobin of 2.5 g/dl) in her early second trimester of pregnancy. The peripheral blood smear revealed mixed nutritional deficiency anemia, while the bone marrow aspirate showed megaloblastic changes. She received blood transfusions, haematinics, vitamin supplements, and adequate nutrition. Following discharge, she attended weekly antenatal clinics with antenatal fetal surveillance until term. At term, she was induced and had vaginal delivery of a healthy baby. She was discharged healthy with her baby and had bilateral tubal ligation at 6 weeks postpartum for a completed family size. This case shows that the morbidities and mortalities associated with severe anaemia in pregnancy are preventable with good multidisciplinary clinical management. The severity of this anemia, her remarkable recovery, and successful outcome make this a rare and noteworthy case report.

Authors: Pillai Swapna Surendran , Hassinar Abeer , Kutty Sathiamma Puthuvilayil , Devi Girija
Published: July 2024

The condition known as spontaneous hemoperitoneum in pregnancy (SHiP) is characterized by an accumulation of fluid in the abdominal cavity and a vague collection of symptoms. Specifically, intrauterine pregnancy increases the chance of death for both the mother and the fetus, making SHiP a potentially lethal illness when it coexists. Here, we discuss two cases of spontaneous hemoperitoneum in pregnancy that resulted from placenta accreta spectrum and endometriosis, and happened in the second and third trimesters, respectively.

Published: July 2024

Choriocarcinoma of ovary is an extremely rare neoplasm. Based on its origin it is gestational and non-gestational. Gestational ovarian choriocarcinoma can arise from an ectopic pregnancy or present as a metastasis from a uterine or tubal choriocarcinoma. Its incidence is 1 in 369 million pregnancies whereas non-gestational ovarian choriocarcinoma originates from germ cells and its incidence is<0.6% of ovarian germ cell neoplasm. A case report of a 26-year-old female came to our hospital with complain of pain in her abdomen with an abdominal mass for 20 days with a history of D&C 1 month back for early pregnancy of 8 weeks, here we investigated and diagnosed her as a neoplastic ovarian mass. Then the patient was taken for exploratory laprotomy with TAH with retroperitoneal mass removal with right ovarian mass removal with sigmoidectomy with colostomy with mesenteric LN sampling. Ovarian choriocarcinoma is difficult to diagnose due to its nonspecific presentation. It is commonly diagnosed after surgical management of abdominal mass. The definitive diagnosis can only be confirmed after molecular genetic analysis. Gestational choriocarcinoma is extremely rare aggressive neoplasm with metastatic transformation having poor prognosis.
Navigating antenatal complexity: a case report of Bombay blood group and anaemia challenges
Authors: Pai Pooja , Hebbar Shripad
Published: July 2024

The Bombay blood group is a rare blood type, predominantly found in regions with a high prevalence of consanguineous marriages due to its autosomal recessive inheritance pattern. This blood group is unique because individuals lack the H antigen, a precursor to the A and B antigens found in other blood types, making their blood type exceptionally rare. Managing antenatal patients with the Bombay blood group presents significant challenges, especially in cases of anaemia or any instance of blood loss. The primary difficulty arises from the scarcity of compatible blood for transfusion, as individuals with the Bombay blood group can only receive blood from other Bombay group donors. This rarity complicates the management of potential complications during pregnancy, labour, and delivery. To address these challenges, minimizing blood loss is essential during all stages of pregnancy, particularly during labour, Caesarean sections, and in the prevention of postpartum haemorrhage. Effective management requires a multidisciplinary approach, involving obstetricians, haematologists, and blood bank services. One potential strategy to mitigate the risk of blood shortages is autologous blood transfusion. This option can be particularly valuable during pregnancy; however, it requires careful consideration of the potential risks and benefits. The procedure should be conducted under the guidance of healthcare professionals experienced in managing such cases, ensuring the safety and well-being of both the mother and the foetus. In our case report, we present an antenatal patient with anaemia and the challenges encountered during the antenatal and postnatal periods. This case highlights the complexities of managing pregnancies involving the Bombay blood group. It underscores the importance of a well-coordinated, multidisciplinary approach to optimize outcomes for both mother and child.

Published: July 2024

Background: It is rare to encounter a gall bladder stones in the paediatric age group. In Saudi Arabia, sickle cell disease (SCD) is common with incidence reach to 19.7%in some provinces. Cholecystitis is responsible for significant morbidity in SCD patients. Laparoscopic cholecystectomy (LC) is now considered as the procedure of choice for treating such cases. Over a period of 3 years, a total of 21 children with sickle cell anemia (SCA) had cholecystectomy. We exclude 3 patients who had splenectomy and cholecystectomy in the same time, the remaining 18 patients (6 males and 12 females) had LC only. Their age ranged from 4 years to 13 years (mean of 7.45±1.94 years).
Methods: LC was the standard procedure performed in all the children in our study group. The mean duration of operation was 92.17±27.31 minutes (range from 62-167 minutes).
Results: The mean post-operative stay after operation was 2.167±0.5 days (range from 1-3 days). One patient required conversion to open cholecystectomy (OC) because of severe adhesions, there were no immediate postoperative complications in the other 17 patients of our study group.
Conclusions: In conclusion, elective LC in well prepared patients, is feasible and safe in children with SCA and should be the treatment of choice for both symptomatic and asymptomatic cholelithiasis. ERCP is a valuable diagnostic and therapeutic investigation both preoperatively and postoperatively.

Authors: Ikram Amna , Sheikh Muhammad A. , Khalid Muhammad Z. , Idrees Amna , Arshad Sikandar A. , Raja Maria I.
Published: July 2024

Background: Hyperaemic suppurative appendicitis, or uncomplicated appendicitis, often requires an appendectomy. Surgical Site Infection (SSI) is common post-surgery, and prophylactic studies show ceftriaxone and metronidazole effectively protect against most causative organisms.
Methods: Ninety patients were included through non-probability convenience sampling. Acute appendicitis was diagnosed using the Alvarado score, with surgery for scores of 7 or higher. A single preoperative dose of ceftriaxone and metronidazole was administered. Follow-up visits included stitch removal on the seventh postoperative day and monitoring up to the tenth postoperative day using the Southampton criteria for wound infection.
Results: Of the 90 patients, 64 (71.1%) were male and 26 (28.9%) were female. Fifty (55.6%) scored 7-8 on the Alvarado score, and 40 (44.4%) scored 9-10. Using the Southampton criteria, 5 (5.6%) developed grade I SSI. Infection rates showed no significant difference between male (3.1%) and female (11.5%) patients (p value >0.05) or by Alvarado score and symptom duration. No cases of SSI beyond grade II were observed.
Conclusions: Administering a single preoperative antibiotic dose effectively minimizes surgical site infection in children with uncomplicated acute appendicitis, demonstrating clear management advantages.
Early versus delayed dressing removal after primary closure of clean and clean contaminated wounds: an observational study
Authors: M. P. Nandan , A. M. Darshan , Prasad Poorna
Published: July 2024

Background: Traditionally, surgical dressings have remained untouched for several days after surgery. However, recent research is exploring the potential benefits of removing dressings sooner. Early removal may offer advantages like quicker detection of infection and improved patient comfort, but it's crucial to determine if it affects healing rates or patient satisfaction compared to the traditional delayed approach.
Methods: A year-long cohort study investigated the efficacy of early (within 48 hours) versus delayed dressing removal 150 post-surgical patients who were divided into two respective groups. Data analysis was performed using statistical software.
Results: Early and delayed dressing removal showed no significant difference in wound complications (p-values > 0.05 for both Chi-square and t-tests). However, patient satisfaction was lower in the early removal group (97 dissatisfied vs 143 satisfied in delayed removal). While the study found no objective benefit to delayed removal, it suggests patients were less satisfied with early removal.
Conclusions: Although there were no statistically significant results between the early and delayed removal of dressing, early removal of dressing had the advantage of cost effectiveness, early detection of wound infection and decreased duration of hospital stay in patients.

Published: July 2024

Deep neck infections are rare but potentially lethal conditions that require prompt identification and management. They can occur in the peritonsillar, submandibular, parapharyngeal and retropharyngeal spaces. The most affected areas tend to differ by age, with tonsillitis being more common in children and odontogenic in older adults. Predisposing factors to infection can also influence location. Early treatment is paramount as airway compromise, septic shock and extension to adjacent structures can lead to morbidity and mortality. Here we report a case of extensive deep neck infection in an elderly diabetic patient with multiple abscesses involving the paraspinal space and extending anteriorly close to the carotid sheet, yet without airway compromise or hemodynamic instability. After further questioning, the likely mode of infection was identified as acupuncture in the affected region. We present a review of the presentations, differential diagnoses, treatments, and clinical course of adults with deep neck infections to highlight the importance of expeditious diagnosis and treatment.

EL TERREMOTO DE LOS MUZOS (1646, ABRIL 3) A LA LUZ DE UN EXCEPCIONAL DOCUMENTO COLONIAL, LA RELACIÓN DE DON BARTOLOMÉ DE MAZMELA Y POVEDA
Authors: Espinosa Baquero Armando
Published: July 2024

Un documento, escrito por el presbítero Don Bartolomé de Mázmela y Poveda a raíz del terremoto ocurrido en la región de Los Muzos el 3 de abril de 1646, da importantes informaciones sobre lo sucedido en toda la región. Los grandes temas tratados por Bartolomé de Mázmela tienen que ver con los daños causados por el sismo en la ciudad y en la región, las réplicas que se sintieron en las semanas siguientes, y las ceremonias de expiación que tuvieron lugar en la ciudad durante unos quince días a partir de la fecha del sismo.
Las valiosas informaciones aportadas por la relación permiten plantear varias ideas sobre el sismo, entre ellas que la posible zona epicentral está al suroeste de Muzo y que se trató de un sismo superficial asociado con una fuente sismogénica importante pero relativamente desconocida hasta ahora. En el aspecto cultural el documento revela el dramático impacto que los sismos, y los fenómenos naturales en general, causaban en la sociedad colonial. Al no tener el más mínimo conocimiento de sus causas, la comunidad estaba condenada a interpretarlos en términos mitológicos.

THE STONE-CECH COMPACTIFICATION IN THE CATEGORY OF SHEAVES OF SETS
Authors: Neira Clara M. , Varela Januario
Published: July 2024

We consider the Category of Sheaves of Sets. The morphisms are chosen in such a way that a change of the base space is allowed via continuous functions. Following M. M. Clementina, E. Giuli and W. Tholen in "Topology in a Category: Compactness", we define a proper (E, M)­factorization system for morphisms and a closure operator with respect to M. The Stone-Cech compactification is defined for any sheaf (E, p, T) of sets by adapting standard germination processes to construct a sheaf over the Stone-Cech compactification BT (of) T. We prove that the sheaf constructed satisfies a suitable universal property characterizing the Stone-Cech compactification of a sheaf of sets.

Se enfatiza cómo la idea de un centro de origen norteño y dispersión a través de una geografía estable predominó en el pensamiento biogeográfico hasta la década de 1960. Durante las últimas tres décadas, Croizat con sus seguidores neozelandeses y su panbiogeografía; Nelson, Platnick y otros con su Biogeografía Cladista o de la Vicarianza, han dominado los aspectos teóricos y metodológicos, cuyas bases son filogenéticas y un cambio en la concepción del espacio geográfico.
