Clinical Characteristics, Treatment, and Prognosis of Patients with Obstructive Jaundice in Tertiary Care Facilities: A Prospective Study
Authors: Behera Sanatan
Published: August 2022

Background: Obstructive jaundice can have a number of reasons, but choledocholithias is the most frequent. Obstructive jaundice patients frequently complain of pruritus, jaundice, pale faeces, dark urine, and yellow skin and eyes. Today, because to improvements in imaging technology over the years, a precise pre-operative diagnosis is nearly always attainable. The study's goals were to examine the clinical characteristics and treatment of patients with obstructive jaundice.
Methods: Patients with obstructive jaundice who were admitted to the Department of Hepatology at SCB Medical College, Cuttack, Odisha, were the subject of the current hospital-based prospective interventional study. Patients of age greater than 12 years of either sex were studied during the study period of two years after providing written consent.
Results: The mean age of the 50 patients was 51.10 years, with 29 (58%) female and 21 (42%) male patients. 19 (38%) of the patients had malignant obstructive jaundice, while 31 (62%) had benign causes. The most frequent symptoms and signs of obstructive jaundice were abdominal pain (100%) and icterus (100%) respectively. The most frequent cancer was cholangiocarcinoma (Ca) of the head of pancreas (Ca) of 2009 (18%), followed by cholangiocarcinoma of the distal common bile duct (CBD) of 2004 (08%), and hilar cholangiocarcinoma of 2003 (06%). The most frequent benign cause was choledocholithiasis 25 (50%) followed by benign stricture of common bile duct 03 (06%).
Conclusion: One of the frequent reasons of surgically treatable jaundice is obstructive jaundice. Its cause is diverse, and the right imaging is typically required for diagnosis. As delayed diagnosis may result in permanent pathological alterations that increase morbidity and death, proper diagnosis and treatment are essential.

Published: August 2022

Despite varying according to the disease and the patient, emotional reactions such as anxiety, depression, regression, anger, and grieving responses are observed in the preoperative period. High preoperative anxiety levels can lead to increased need for postoperative pain relief, prolonged hospital stay, inadequate patient satisfaction and insufficient patient recovery.In the present study, it was aimed to measure preoperative anxiety and depression levels and to determine their relationship with quality of recovery in patients scheduled to undergo elective surgery under general anesthesia. A total of 137 patients older than 18 years of age who were planned for elective surgery and who were to be operated under general anesthesia were included in the study. In the preoperative period, the patients were asked to fill out the demographic information form, Beck anxiety inventory and Beck depression inventory. They were also asked to complete the quality of awakening and the quality of recovery questionnaires at the postoperative first day and first month.It was detected that the anxiety and depression scores were high, whereas the recovery quality was low in females. The depression scores of the patients who were college graduates were found to be low. It was observed that the quality of awakening and the quality of recovery values at the postoperative first day and first month were significantly lower in the patients with higher depression and anxiety scores. According to these results, reducing the anxiety and depression of the patients in the preoperative period to a minimum is necessary to minimize the negative effects in the postoperative period such as inadequate patient recovery, increased need for painkillers, long hospital stay and insufficient patient satisfaction.

Published: August 2022

Background: Outbreaks of contagious ecthyma (CE) are frequently reported in sheep and goats flocks in Nigeria with severe clinical outcomes. CE is a debilitating and economically important disease primarily affecting sheep and goats caused by the Orf virus (ORFV). Despite field reports of CE in the country, there is no concise country-wide epidemiological data on the disease and limited genetic data of circulating Nigerian ORFV are available in the public domain.
Aim: An epidemiological survey of CE and molecular characterization of ORFV circulating in Nigeria from 2014-2016
Method: Data were collected using questionnaires designed and administered to veterinarians and farmers in selected States of Nigeria. Samples collected during passive surveillance for CE from 2014 to 2016 were analyzed by polymerase chain reaction (PCR). The A32L and B2L genes of circulating ORFV were characterized.
Results: Analysis of the questionnaire showed that 69.54% (n=82/118) of the farmers claimed to have experienced CE in their flocks with average morbidity and mortality rates of 25% and 15%, respectively. A total of 113 veterinarians participated in the study, with 69.9% (n=79) familiar with CE and claimed CE causes morbidity rates of 25%-37% and mortality rates of 10%-15% in sheep and goats. Laboratory results revealed that ORFV was detected in 72% (18/25) of outbreak samples analyzed by Real-time PCR. Phylogenetic analysis of A32L and B2L genes revealed that Nigerian ORFV sequences belong to cluster I and II and are similar to viruses from India, Ethiopia and China.
Conclusions: This study is the first nationwide epidemiological data on the status of CE in sheep and goats in Nigeria. It is also the first report of molecular characterization of two genes of ORFV circulating and causing outbreaks in small ruminants in the country. This study showed that CE is under-reported, widespread and of economic importance to sheep and goat farmers in Nigeria.

Authors: KAPLAN Ayşe Gül , KAPLAN Alper
Published: August 2022

For the sustainable development of nations and to lessen the negative environmental effects of fossil fuels, more clean and renewable energy sources are now required. One of the most significant energy sources is solar energy. To utilize solar energy more efficiently in a particular area, it is crucial to be aware of the solar radiation levels. Furthermore, it's critical to accurately calculate solar energy for study into climate change, one of the biggest global challenges. Systems that utilize solar energy are frequently used nowadays to address the rising global need for energy. The high geographical and temporal resolution, global, diffuse, and direct sunlight data needed for the design and effective operation of solar power plants are now provided by satellite-based solar radiation predictions. In this work, satellite-based forecasting models were used to estimate diffuse solar radiation for the chosen region. In this study, the solar radiation irradiance values of the chosen region were estimated using the curve fitting approach. Angstorm coefficients were determined using the Matlab program for this investigation. Various statistical error analysis tests were used to evaluate how well the constructed model performed. The findings collected unequivocally demonstrate that the provided prediction models perform well.
The Impact of minimalism on product Design: A Case study of Muji
Authors: Li Yao , Huang Pan
Published: August 2022

Simplicity and naturalness, and a focus on product materials and functionality itself are typical features of the minimalist style, which, as a popular modern design style, has also had a profound impact on product design. Muji develops minimalism in its design philosophy and product content, espousing a philosophy of simple and natural living and the removal of superfluous decoration. The appearance of the products is presented only through the use of simple lines and geometric shapes, the use of high purity colours to return the properties of the raw materials themselves, and the use of environmentally friendly recycled materials to simplify the packaging to its most basic state. The product is presented to the consumer in a minimalist manner, while retaining its functionality and practicality. Taking Muji as an example, this article explores the application of minimalism in Muji's design from both the design concept and the product, and analyses the reasons for its transformation from an 'unbranded' to a 'branded' brand.

DEBRIDEMENT IN DIABETIC FOOT ULCER
Authors:   Department of Pharmacy, Negelle Health Science College, Guji, Ethiopia, Bereda Gudisa
Published: August 2022

Wound debridement is defined as the removal of foreign material and dead contaminated tissue from (or adjacent to) a traumatic or infected lesion to expose healthy tissue and removal of foreign material that has become embedded in the wound. The main reason for debriding a wound is to avoid substratum for bacterial growth, ongoing inflammation, and leukocyte infiltration with delayed progression to the proliferative and remodelling phases of wound healing, compromised restoration of the structure and function of the skin, odor management issues, and other negative effects. The objective of operative debridement is to remove all hyperkeratotic tissue (ie, callus), necrotic tissue, functionally abnormal senescent cells, and infected tissue, all of which inhibit wound healing. The International Working Group on the Diabetic Foot recommended the application of sharp/surgical debridement in preference to other techniques such as topical debridement agents (i.e., autolytic dressing or biological debridement) because it is the least expensive, fastest method of wound bed preparation and is available in all geographic areas.

Systemic inflammatory diseases are characterized by multivisceral involvement at some point in their evolution. This involvement can concern almost all organs, including the heart. Each systemic condition has a unique cardiac expression. The target of this study is to determine the frequency of cardiac involvement in systemic inflammatory diseases. This study is a cross-sectional, descriptive, and analytical study that was conducted within 07 months. The aim was to screen 23 patients followed for systemic inflammatory diseases for cardiac involvement. The mean age was 44 (±12) years old with a minimum of 24 and a maximum 64 years. Most of patients were women with a sex ratio (M/F) of 0.09. An echocardiographic abnormality was found in 26.1% of patients and 73.1% had an ECG abnormality. They included left atrial hypertrophy (43.4%), left ventricular hypertrophy (30.4%), right axial deviation (26.1%), low voltage (21.7%), right atrial hypertrophy (8.6%), S1Q3 appearance (8, 6%), pulmonary hypertension (8.6%), repolarization disorders (8.6%), sinus tachycardia (8.6%), middle tricuspid insufficiency (4.3%), middle pulmonary insufficiency (4.3%), and pericarditis (4.3%). Patients with systemic inflammatory diseases had cardiac disorders with rare clinical manifestations but with an incidental discovery either on ECG or on cardiac echodoppler. Hence, a systematic cardiac exploration in these patients was essential.
Role of Hydrogen Flow Rate for the Growth of Quality Nanodiamonds via Microplasma Technique

Published: August 2022

Nanodiamonds (NDs) were prepared by utilizing a microplasma facility. Ethanol and Argon mixture was decomposed in microplasma for the formation of NDs. In order to stabilize the NDs growth, the Hydrogen was added in the mixture during the growth process. Hydrogen flow rate was changed from 1 to 5 L/min to find out the optimum flow rate for the growth of stabilized NDs. The experiments were also performed without the introduction of Hydrogen for the comparison. TEM and Raman analysis confirm that the highest quality diamonds are obtained at Hydrogen flow rate of 3L/min. In the case of Hydrogen, the SAED patterns reveal the presence of pure diamond phases which in turn envisages the etching of graphitic shell. TEM micrographs reveal that the size of NDs produced at 3 L/min Hydrogen flow rate ranges from 1~20 nm which is much smaller than that of without Hydrogen (4-32 nm). EDX spectra also disclose the Carbon peak with a maximum intensity for 3 L/min flow rate. UV-Visible and PL spectroscopy analysis indicate the presence of Nitrogen-Hydrogen defect centers. However, a decrease in defect density at 3L/min indicates the production of improved quality NDs. FTIR also verifies the removal of graphitic shell around NDs at 3 L/min flow rate. Moreover, high hydrogen flow rates effectively incorporate nitrogen vacancy (NV) defects. Prepared NDs offer emerging applications in optoelectronic systems, biomedical nanodevices and nanoscale sensors for electric field, magnetic field & temperature.

Both HIV-1 and Toxoplasma gondii are able to invade central nervous system and affect its functionality. Advanced HIV-1 infection has been associated with defects in immune response to T. gondii, leading to reactivation of latent infections and the appearing of toxoplasmic encephalitis. This study evaluated changes in the immune response to T. gondii in different stages of HIV infection. Immune response to T. gondii was assessed studying cytokine production in response to parasite antigens in HIV-1-infected/T. gondii-non-infected (P1), HIV-1/T. gondii co-infected (P2), HIV-1-non-infected/T. gondii-non-infected (C1) and HIV-1-non-infected/T. gondii-infected (C2) individuals. Patients (P1 and P2) were divided in early/asymptomatic (P1A, P2A) or late/symptomatic (P1B/C, P2B/C) according to peripheral blood CD4+ T lympho-cyte counts (>350 or <350/μL, respectively). The HIV-1 infection, from early/asymptomatic stages, was associated with significant lower production of IL -2, TNF-α and IFN-γ in response to T. gondii, when P2 patients were compared with C2 controls. These early defects may impair anti-parasitic response in co-infect-ed patients, allowing to reactivation of parasitic latent infection, enhancing the risk of CNS damage and impairment of neurocognitive functions.
Calcinosis escrotal idiopática: Reporte de un caso.
Authors: Bouquett Vanessa , Sánchez Letmarié
Published: August 2022

Calcium participates in many physiological processes. Calcinosis cutis is a disease caused by calcium deposition in the dermis. Idiopathic scrotal calcinosis (ICS) is a common form of idiopathic calcinosis cutis. A 28-year-old male patient was evaluated, with symptoms of multiple white masses in the scrotum, of various sizes, not painful. Calcium and phosphorus levels were with-in normal ranges, characteristic of idiopathic calcinosis, while vitamin D and PTH were outside the normal limits. Minor surgery was performed on circum-scribed nodular lesions of various sizes with regular borders. Post-biopsy histo-logical examination confirmed the diagnosis of calcinosis cutis. A low-calcium diet was prescribed as a long-term preventive method. Despite the infrequency of this condition, it should be taken into account when making a differential diagnosis. Its etiology is still unknown and it can present asymptomatically. The important thing is to provide the patient with a better quality of life, avoid discomfort and low self-esteem due to the aesthetic aspect.

Introduction: Effective medical dissolution therapy (MDT) for uric acid stones is more cost-effective than surgical treatment; however, treatment failure may be associated with increased cost. We aimed to study the cost-effectiveness of MDT for uric acid stones vs. surgical management.
Methods: We performed a retrospective study within our institution of all patients receiving MDT for uric acid stones from 2008–2019. All patients had a known history of uric acid stones, urine pH ≤5.5, and <500 Hounsfield units on preoperative computed tomography (CT). The cost of treatment in the dissolution group was compared to the cost of primary surgical treatment in a theoretical matched cohort. Cost was estimated using local Medicare reimbursement scales. Statistical analysis was performed with SPSS Statistics.
Results: A total of 28 patients were identified, of which 18 were included in the study. Complete and partial dissolution occurred in six (33%) and four (22%) patients, respectively. Five (28%) patients developed symptoms and underwent ureteral stent placement. Ureteroscopy and percutaneous nephrolithotomy (PCNL) were each performed in three (17%) patients in whom dissolution treatment was not effective on followup CT. Following dissolution trial, six (33%) patients had residual stone burden requiring surgical intervention. The average cost of treatment, including surgeries was $14 604 in the dissolution group vs. $17 680 in the surgical cohort. The average cost to achieve stone-free status in patients with complete, partial or no response to dissolution were $1675, $10 124, and $21 584, respectively, while primary surgical treatment for the same patients would cost $15 037, $10 901, and $20 511, respectively.
Conclusions: Successful MDT is highly cost-effective. Incomplete response to dissolution can stem from several reasons and contributes to higher costs and likely decreased quality of life.

Published: August 2022

Introduction: Benign prostatic hyperplasia (BPH) is a common condition affecting aging men. While holmium laser enucleation of the prostate (HoLEP) is one of the most effective treatments for BPH, variations of the procedure, such as median lobe HoLEP (MLHoLEP), are rarely reported. Here, we report our institution’s experience with pHoLEP.
Methods: Our institutional prospective database was queried for patients having undergone median or individual lateral lobe enucleation between 2007 and 2018. A control cohort of patients who underwent standard HoLEP (sHoLEP) was identified using 1:2 propensity score matching based on age, prostate size, maximal flow rate (Qmax), postvoid residual volume (PVR), and AUA symptom score (AUAss). Three and 12-month AUAss, PVR, and Qmax were compared.
Results: Forty-seven patients were identified as having undergone MLHoLEP. At three-month followup, AUAss (p<0.01) and incontinence rates (p=0.045) were lower for MLHoLEP patients, in addition to them having shorter operative (36.5 mins vs. 64.5 mins, p<0.01) and enucleation (13.8 mins vs. 37 mins, p<0.01) times as compared to sHoLEP patients. No difference was noted between MLHoLEP and sHoLEP cohorts with respect to age, prostate volume, PVR, or Qmax. Significant improvement in AUAss, PVR, and Q max from baseline to three and 12 months was noted overall in both groups.
Conclusions: MLHoLEP could provide a surgical option with reduced operative time, quicker improvement in AUAss and restored continence in appropriately selected patients. Ultimately, MLHoLEP represents a safe and effective treatment option to select patients who may not be eligible for or face potential morbidity concerns associated with sHoLEP.

The agricultural sector, especially fisheries, has played an important role in the social and economic development of the Indonesian state, because the indonesian population has a daily life as farmers, and the territory of Indonesia 2/3 is the water area. Mulyoagung Village in Ngantang District is one of the villages located in the area around the Selorejo reservoir. In addition to farming, the main income of the community is dependent on the existence of the Selorejo reservoir, which is catching fish. Fish catches are sold in their unprocessed state to middlemen at a very low price since they lack the knowledge to process fish into various processed foods. Only about a year ago there was an attempt not to sell the fish in its raw condition, but to be sold in a mature state, in the hope that the price would be higher and not be played with by middlemen. By adopting from crispy mushrooms, baby fish is processed in crispy form. Through various trainings and assistance, including training on making crispy various flavors of basic uceng and wader fish, frying techniques, oil slicer techniques, product packaging as well as labeling and marketing, There has been steady growth in both the quantity and quality of this business, and it is now even being exported off the island.

Published: August 2022

In Mergosono Village, the program for using terraces to grow crops was carried out more than 5 years ago, through an “urban farming” program led by PKK women. There were more than 50 mothers who were involved in this activity. Through urban farming, each house is recommended to plant more than 10 potted plants, with various kinds of plants, such as: chilies, tomatoes, cabbage, eggplant, pok cay, mustard greens, and flowers. At first this activity only aimed to maintain the beauty of the village, so that it remains beautiful, but gradually it can be used to meet daily food needs, especially vegetables and "empon-empon". Even though this activity has been going on for more than 5 years, there are still many obstacles that they face, including: 1) PKK women are still not able to make special planting models for limited land, be it hydroponics or verticulture, therefore only polybag or pot models; 2) it is difficult to make a fertile planting medium, it seems that there are some plants that grow less healthy; 2) have not been able to create their own nurseries and have difficulty moving plants from the nursery box to pots or polybags; 3) have not been able to make environmentally friendly fertilizers (organic or compost); 4) have not mastered how to fertilize and when to fertilize properly; 5) do not understand good plant care techniques, do not know plant pests, and eradicate them, how to handle weeds). Therefore, assistance is needed to solve these problems in the form of technology transfer through training activities, mentoring, demonstration plots or direct practice.

Uncoupling Conceptual Understandings and Political Preferences: A Study of Democratic Attitudes among Singapore's Highly Educated Young People
Authors: Osterberg-Kaufmann Norma , Teo Kay Key
Published: August 2022

Democracy is subject to constant and seemingly interminable contestation in academic and policy contexts, and yet, empirically and methodologically robust analysis of what the term means in practice for actual citizens has remained an area of relative lacuna. Admittedly, large-N surveys have attempted to address this research gap by examining attitudes to numerous components of democracy, but without the fine-grained detail required to overcome simply reproducing the focus on liberal procedural, Western precedent-based, top-down approaches to understanding such a complex and varied political system. This article proposes a methodological approach, based on the requirements of comparative political theory and research into how people view democracy. This allows us to explore political attitudes and the meaning of democracy with a bottom-up approach using the methods of repertory grid and in-depth interviews. Singapore is a particularly exciting case for comparative political science: although it has all the advantageous conditions that, according to classic modernization theory, promote the development of democracy, it is still not a democracy.
 To what extent will the conceptualization of democracy by citizens in a country like Singapore resemble theoretical definitions, and how suitable do they consider democracy to be for Singapore? What are their expectations for a good government or regime? This article examines what highly educated Singaporeans, ranging in age from their twenties to their forties, think about democracy. In doing so, the article also pursues the goal of comparing methods between repertory grid interviews and in-depth interviews in order to work out potential interfaces, and points of connection, between the two methods to allow for the most productive research outcomes. We find that, conceptually, these Singaporeans' perceptions of democracy appeared very similar to what is usually discussed as electoral democracy in established literature. When evaluating the performance of a government or a regime, however, liberal ideas of freedom and fairness competed with more pragmatic approaches that reflect the principles of progress and success as well as community and performance-focused orientations. As a result, our respondents did not prioritize democratic practices as much as other aspects of governance like e ciency. Our findings on the influence of state ideology on highly educated young people in Singapore strengthen the arguments of political myth as an integration and legitimization strategy in autocratic regimes and democratizing strong states or regimes with a particularly pronounced ideological hegemony.
