Las implicaciones de ser asocial en las redes sociales
Authors: Skoric Marko M. , Zhu Qinfeng 
Published: December 2022

Los primeros estudios sobre redes sociales respaldaban visiones optimistas en relación con su impacto positivo en el desarrollo del capital social, y relacionaban su uso con la exposición a puntos de vista más diversos y a un mayor compromiso con la sociedad. Sin embargo, recientemente, los investigadores empezaron a analizar los comportamientos asociales que se pueden llevar a cabo en las redes sociales y a estudiar sus consecuencias sobre el desarrollo del capital social. En este ensayo, revisamos la literatura existente centrada en estudiar estas prácticas de evitación y desconexión selectiva y avanzamos en el concepto de ‘espacios digitales seguros’ -entornos online creados filtrando y eliminando post hoc a contactos en redes sociales-, con el objetivo de profundizar en el debate sobre sus consecuencias en las sociedades democráticas contemporáneas. Nuestros hallazgos apuntan al hecho de que los espacios digitales seguros pueden constituir un entorno fértil para la expresión cívica y política, especialmente para las minorías. Sin embargo, la creación de estos enclaves digitales puede también alejar aún más a las minorías del consenso político generalizado y podría llevar a una reducción de las oportunidades económicas y políticas de aquellos ciudadanos que están excluidos de los “espacios seguros”.

Authors: Sanglodkar Uday , Jain Mayank , Venkataraman Jayanthi 
Published: December 2022

Background and Aim:
Diuretic doses for the optimal management of ascites may be influenced by the patient profile and conditions. We undertook this study to map the usage of common diuretics, alone or in combination, for the management of patients with decompensated cirrhosis and to determine the prevalence of adverse effects with the administered regimens and factors that predict the need for paracentesis while on diuretics.

Methods:
This prospective study was done in an outpatient clinic among patients with known liver cirrhosis, irrespective of etiology, belonging to Child-Pugh Class B or C, with mild to moderate ascites and no dyselectrolemia on diuretics. The primary outcome of the study was the need for paracentesis. The type and dose of diuretic at this instance were noted.

Results:
A total of 200 patients (168 male), predominantly from southern Indian states, formed the study group. The median model for endstage liver disease score was 18 and 70% of cases required paracentesis within 3 months. The single diuretic agent was used in 18% of cases while combination of two diuretics was used in 82%. Spironolactone was the most common single agent used (26, 72.2%). The combination of furosemide and spironolactone was the most common diuretic combination used (89.6%, 147 cases). One hundred and thirty patients (65%) reported the adverse effects to diuretics. Renal dysfunction and electrolyte disturbances were the most common adverse effects. Adverse effects to diuretic use and frequency of large volume paracentesis were significantly more common in patients taking furosemide 40 mg and spironolactone 100 mg per day.

Conclusions:
Indian patients with decompensated chronic liver disease do not appear to tolerate the high doses of diuretics and 65% of them develop diuretic-related adverse effects. There is a need to formulate the guidelines for the optimal management of ascites in decompensated chronic liver disease in the Indian setting.

Authors: Jain Mayank , Sanglodkar Uday , Venkataraman Jayanthi 
Published: December 2022

Background and Aims:
Immunization against hepatitis A, hepatitis B, and pneumococcus has been recommended in patients with cirrhosis of the liver. This questionnaire survey was undertaken to determine the rates of vaccination against these organisms in a cohort of patients with liver disease in India.

Methods:
We included all patients who were willing for the study and had been seen by a gastroenterologist/hepatologist at least once. Patients offering incomplete information were excluded from the study. Serological tests for confirmation of immunological response were not done. Details of counseling and vaccination status for hepatitis B, hepatitis A, and pneumococcal infection were noted.

Results:
A total of 305 patients (272 males, 89%) formed the study cohort. The median age was 60 years (range 27–76 years) and the median duration of liver disease was 12 months (1–120 months). The median model of end stage liver disease (MELD) was 14 (range 7–35). Only 37 (12.1%) patients reported that they had been counseled for vaccination against these infections. The rates of vaccination were very low (<10%).

Conclusion:
Very dismal vaccination rates were noted in Indian patients with liver cirrhosis.

Context:
Oral squamous cell carcinoma (OSCC) is the most common malignancy of oral cavity. OSCC shows geographical variation with respect to the age, sex, site, and habits of the population. In general, OSCC is most commonly seen in men in the 6th to 8th decades of life and is rare in patients younger than 40 years. In recent years, it have been observed an increased incidence of OSCC in young individuals.

Aims:
To compare and correlate the clinical parameters of OSCC in different age groups.

Settings and Design:
Ninety histopathologically diagnosed cases with OSCC were included in our prospective study. These patients were divided into three groups: Group I: 30 patients below 40 years of age; Group II: 30 patients who were between 41 and 60 years of age; and Group III: 30 patients who were above 60 years of age.

Subjects and Methods:
The relevant information regarding clinical parameters, i.e., age, sex, site of lesion, risk factors, duration of habit, tumor, node, metastasis (TNM) staging, and clinical diagnosis were collected and tabulated.

Statistical Analysis Used:
The Chi-square test was applied to evaluate the significant difference among different age groups.

Results:
There was a statistically significant difference in the duration of habit and TNM staging among different age groups.

Conclusions:
OSCC in different age groups shows some differences as well as similarities in the parameters that were analyzed.
Production of α-Amylase from Bacillus megaterium MD-1
Authors: AGÜLOĞLU FİNCAN Sema , ENEZ Bariş 
Published: December 2022

The alpha-amylase is used extensively in many different industrial sectors and is renowned for modifying starch by rupturing 1-4 glycosidic bands. Depending on the intrinsic properties of the microorganism, several alpha-amylases with thermostable and halotolerant properties are expressed. In the current study, the bacteria were isolated from Ergani Makam Mountain. Identification and optimization of the isolated bacteria were performed. As a result of the 16S rRNA analysis, physiological, morphological and biochemical analyis were carried out for the identification of the isolated microorganism and consequently the bacterium was defined as Bacillus megaterium MD-1.
Following its identification, α-Amylase, was isolated from B. megaterium. Optimal conditions for bacteria and enzyme production were determined as 48 hours, 35°C and pH 7.0. Maximum enzyme activity was optained at 40°C and pH 8.0. The effects of various carbon and nitrogen sources on enzyme production were investigated by adding to the nutrient medium. Compared to the control regarding enzyme production, it was determined that carbon sources, particularly sucrose, fructose and lactose inhibited enzyme production by 75%, no change on the other hand was observed in glucose, starch and galactose. It was also observed that urea and sodium nitrate from nitrogen sources had an inhibitory effect on enzyme production whereas other nitrogen sources did not. The highest amylase production among nitrogen sources was obtained with peptone addition.
In our study, it was determined that an increase in amylase activity could be achieved by using the optimum values of physical parameters.

Objective: To identify populations at risk for lost to follow-up while undergoing management of brain tumours in a low-resource setting.
Methods: A retrospective study was conducted at the neurosurgical centre on patients presenting with a brain tumour from January 1, 2019, to December 31, 2019. Data on demographic characteristics, surgical characteristics, treatment, and outcomes such as mortality status, were collected by manual chart review. LTFU was defined as patients discontinuing clinical follow-up at the institute of surgical consultation within two years from the initial visit. Univariate (odds ratio) and multivariate (b-coefficient) logistic regression were used to determine factors' significance for LTFU.
Results: From a total of 2750 patients from 32 centres, 1140 (41.4%) were LTFU during the study period. Of these 1140 LTFU patients, 156 (13.7%) were LTFU without any intervention, 984 (86.3%) were LTFU after the primary surgery, and 872 (76.5%) patients were LTFU without any adjuvant treatment. On univariate analysis annual hospital case volume (p< 0.001), older age group (15-39 years (p=0.037) and ?40 years (p= 0.016)), and non-surgical treatment (p<=0.026) correlated with a higher risk of LTFU. Belonging to the middle-class cohort was correlated with a better chance of follow up (p=0.001). Multivariate analysis demonstrated that larger centres had the largest b-coefficient of 1.53 (95% CI= 1.3-1.8, p< 0.001).

Conclusion: Our study demonstrated that almost half of patients diagnosed with brain tumours were LTFU within two years of diagnosis. Larger centres, non-surgical treatment, and older age seem to be associated with higher LTFU. Identifying vulnerable populations will allow the need-based provision of care and follow-up to improve health outcomes.

Objective: To define the landscape of treatment patterns and current epidemiological data regarding gliomas in Pakistan.
Methods: As part of the Pakistan Brain Tumour Epidemiology Study (PBTES), data were collected from 32 neurosurgical centres across the country. Our retrospective study looked at patients who underwent surgical procedures for gliomas in 2019 in neurosurgical centres. The data was collated and analysed using STATA version 15.
Results: A total of 781 patients with gliomas were identified 479(61.8%) in public sector hospitals, 302(39.1%) in the private sector). The most common histopathological subtypes were glioblastoma 262 (33.5%), followed by astrocytoma 147(18.8%) and oligodendroglioma 93(11.9%). Gender distribution was skewed towards men 508(65%). Private institution hospitals performed surgical biopsies as the first surgical procedure 75(23%) more often than public hospitals 38(9%). Chemotherapy was given to 115(29.8%) patients, and there was no data regarding 467(53%) of patients. Similarly, only 202(43.9%) patients received radiation therapy, and there was no data for 469(60%) of patients. For high-grade gliomas specifically, only 95(31.8%) patients with HGG have a record of receiving radiation therapy, and only 57(18.9%) had a record of being started on chemotherapy.
Conclusions: Our study highlighted gaps in glioma management within Pakistan, with only around half of our
patients receiving chemotherapy and radiotherapy, despite it being indicated. In our experience, high-grade
tumours were diagnosed at a younger age than in high-income countries, but overall, glioblastoma was a smaller
constituent of our tumour sample than expected.

Authors: Musdalifah Musdalifah 
Published: December 2022

Deformasi pada lapisan pondasi dapat menyebabkan kerusakan lapisan beraspal diatasnya, salah satunya dalam bentuk cracking atau retak. Kondisi tanah setempat atau tanah yang ada dilapangan tidak selalu sesuai dengan persyaratan yang ditetapkan. Penelitian ini bertujuan untuk menganalisis deformasi tanah lempung yang diperkuat dengan konfigurasi bucket geogrid. Pengujian dilakukan dengan beberapa tahap yaitu menguji sifat fisik dan mekanik material tanah dasar lempung dan sirtu menggunakan standar SNI dan ASTM. Pengujian deformasi tanah dilakukan dengan model fisik laboratorium melalui desain yang dibuat menggunakan metode pengujian pelat pembebanan pada bak uji berukuran 180 x 50 x 100 cm yang menggunakan perkuatan konfigurasi bucket geogrid dengan empat variasi model, yaitu tanpa perkuatan, dengan perkuatan bucket geogrid tipe tunggal, sejajar dan interlock. Hasil penelitian menunjukkan tanah timbunan tanpa perkuatan saat dibebani maksimal mengalami keruntuhan sebesar 42,5 kN dan mengalami penurunan yang sebesar 3,7 % dari tinggi lapisan pondasi. Sementara sampel-sampel dengan perkuatan bucket geogrid tipe tunggal, sejajar dan interlock pada beban yang sama mengalami penurunan sebesar 3,5 % ,2,8 % dan 1,91 %. Dengan menggunakan perkuatan bucket geogrid tipe tunggal, sejajar dan interlock dapat mencapai beban ultimit hingga 45 kN, 50 kN, dan 55 kN. Dari hasil penelitian dapat disimpulkan bahwa perkuatan dengan konfigurasi bucket geogrid tipe interlock lebih efektif mereduksi penurunan akibat pembebanan yaitu sebesar 1,91% sehingga dapat lebih meningkatkan daya dukung tanah
