Authors: Hamedani Narges Amani , Pirestani Majid , Dalimi Abdolhossein
Published: December 2022

Objective:

To evaluate the clinical and molecular features of human cystic echinococcosis in Tehran, Iran.

Methods:

In this cross-sectional study, all human cystic echinococcosis patients admitted to Tehran’s hospitals from 2011 to 2019 were enrolled, and demographic characteristics, clinical findings, and laboratory data were collected. Formalin-fixed, paraffin-embedded and fresh tissue samples of 175 cystic echinococcosis patients were evaluated for molecular characterization. The samples’ isolated DNA was used to amplify cytochrome c oxidase I and NADH dehydrogenase subunit I genes. Also, the morphological features of fresh samples were examined.

Results:

In total, 175 patients with a mean age of 45 (9-98) years were admitted to Tehran’s hospitals diagnosed with cystic echinococcosis. Moreover, the highest (26.9%) and the lowest (2.9%) prevalence of cystic echinococcosis cases were in the 16-30 and 1-15 years range, respectively. Male/female ratio was 0.96 (49.1% vs. 50.9%). The liver was affected in 92 patients (52.6%), and two or more organs were infected in 7 patients (4.0%). The cysts’ diameter varied from 1 to 25 cm, and 96.0% of the patients had a single hydatid cyst. All patients underwent radical surgery and the PAIR technique was applied for all cases. No significant difference was observed between the protoscolex hooks of pulmonary and hepatic cysts. G1-G3 had the highest percentage (99.4%) over other identified G6 genotypes (0.6%).

Conclusions:

The sheep-dog cycle plays an important role in transmitting the human cystic echinococcosis infection in Tehran.

Quality Assessment and Outcomes Related to Deceased Organ Donation in a Tertiary Care Hospital in India an Observational Study
Authors: Seth Avnish Kumar , Singh Twinkle
Published: December 2022

Background:

We report quality assessment (QA) at each step of organ donation (OD), from the identification of a prospective donor with suspected brain death (BD) to organ retrieval.

Methods:

Case summaries and files of patients who expired or left against medical advice (LAMA) in 2019 in a 290-bed hospital were studied. Possible, potential, eligible, and actual donors were identified from among those with devastating brain injury (DBI). Potential donors (PDs) were subclassified into five types. The structure, process and outcomes related to OD were evaluated with appropriate Quality Indicators and Quality Criteria.

Statistical Analysis:

Data were analysed using MS Excel and we have used cross tabulation method for statistical analysis.

Results:

Of 352 deaths, 324 occurred in intensive care units (ICUs), of which 210 were reported from medical and surgical ICUs. ICD-10 codes relevant to process of OD were found in 27 patients, of whom 16 (7.6% of deaths) received ventilatory support and were possible donors. BD was suspected by ICU teams in 10 patients (4.7% of deaths), labeled as PDs. The presence of nonreactive pupils were recorded in 10 (100%) case files and 5 (50%) death summaries, while other brain stem reflexes were endorsed in 6 (60%) case files and none of death summaries. Rates for referral, contraindication, request, and consent were 80%, 40%, 66.6%, and 50%, respectively. From 20 patients with DBI who LAMA, 11 possible donors and five PDs were identified.

Conclusion:

Retrieval of data relevant to OD is possible by auditing the available mortality and LAMA records in India. Formatting of death summaries in patients with DBI to include Glasgow Coma Scale and all brain stem reflexes would help in the process of QA for OD.

Authors: Rao Namrata S. , Chandra Abhilash , Saran Sai , Singh Amit Kumar , Singh Sanjeet Kumar
Published: December 2022

Background:

Kidney transplant recipients (KTRs) are deemed to be at a high risk of severe coronavirus disease (COVID-19). Herein, we describe the clinical, laboratory profiles, management, and outcomes of 26 KTRs who developed COVID-19 during the first and second waves of the pandemic from a tertiary care center in northern India.

Methods:

This retrospective observational study included KTRs detected with COVID-19 infection during the first wave (March–November 2020) and the second wave (March–July 2021). Their clinical and laboratory investigations, management aspects, and outcomes were compared, using data retrieved from clinical and telenephrology records, and the hospital information system.

Results:

Of the 23 KTRs, 20 were male (86%), 20 patients had fever (86%), and cough and breathlessness were seen in 19 (82%) and 12 (52%), respectively. Acute graft dysfunction was seen in 6 (26%) patients, and the need for renal replacement was seen in 4 (17%) patients. Supplemental oxygen by reservoir mask was utilized in 10 (43%) patients, high-flow nasal cannula in 3 (13%), noninvasive mechanical ventilation in 4 (17%), and invasive mechanical ventilation in 6 (26%) patients. All the KTRs with moderate and severe COVID illness and 6/7 nonsurvivors were infected during the second wave. Overall mortality in this group of patients was very high at 27%, and the mortality in the group on mechanical ventilation was 100%.

Conclusions:

The second wave of the COVID-19 pandemic was associated with greater severity of illness and high mortality in KTRs.

Authors: Patil Shivakumar S. , Sharma Ashish , Kenwar Deepesh Benjamin , Vijayvergiya Rajesh , Singh Sarbpreet
Published: December 2022

Ipsilateral acute iliofemoral deep venous thrombosis (DVT) after a renal transplantation, although rare, has a high morbidity, causing complications such as allograft failure, rupture, or death. Treatment modalities are limited due to the risk of bleeding and impaired renal function. We report successful treatment of a case of iliofemoral DVT in a 58-year-old male recipient of a living donor renal transplantation. The immediate postoperative course of the patient was uneventful, and he was discharged on 6th postoperative day (POD) with serum creatinine of 0.8 mg/dl. On POD 26, the patient was admitted with diarrhea, dehydration, and decreased urine output. His serum creatinine rose from 0.8 mg/dl to 2.6 mg/dl and he developed pain and swelling of the right lower extremity. Duplex ultrasonography was suggestive of acute DVT with noncompressible right distal external iliac vein, common femoral, superficial femoral and popliteal veins, absence of color flow from the right femoral vein to the common iliac vein, dilatation of allograft renal vein and an increased renal graft resistive index of 0.97. After inferior vena cava filter insertion, initial treatment with percutaneous balloon angioplasty and catheter-directed thrombolysis could not restore blood flow. Subsequently, percutaneous transluminal pharmacomechanical aspiration was performed with complete removal of the thrombus leading to restored renal allograft vein patency and normalization of allograft function and Duplex findings.

Authors: Kumar K. Vinod , Unni V. Narayanan , Warrier Anup , Prasannan Bipi
Published: December 2022

Solid organ transplant (SOT) recipients are at increased risk of opportunistic infections, as they are on immunosuppressive drugs. The risk increases if the cumulative immunosuppression is high, especially when the patient is treated for acute rejection episodes. Multiple opportunistic infections in the same patient are reported in SOT recipients. We report a 43-year-old man, renal allograft recipient, 15 years posttransplant, on dual immunosuppression who presented with fever, generalized skin rashes, and altered sensorium. He was recently treated with pulse methylprednisolone injections for acute graft rejection episode. He had multiple pustules all over the body, predominantly over the face, eyelids, chest, and lower limbs. Pus from the facial lesion grew Nocardia, and tissue culture of skin ulcer from the leg grew nontuberculous mycobacteria. Combined infection with these organisms posed diagnostic challenge as both can present with cutaneous manifestation, both organisms are acid-fast bacilli, and both organisms were detected and grown from the sample taken from one of the large skin ulcers. It was important to identify both the organisms from the skin ulcer as the treatment options are different.

Published: December 2022

Cellular and humoral responses are required for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) eradication. Antigen-presenting cells load SARS-CoV-2 peptides on human leukocyte antigen (HLA) with different avidities and present to T- and B-cells for imposing humoral and cellular responses. Due to immunosuppression, renal transplant recipient (RTR) patients are speculated to poorly form the antibody against the SARS-CoV-2. Therefore, determining the association of specific HLA alleles with anti-SARS-CoV-2 spike protein antibody formation will be helpful in managing the RTR having specific HLA alleles from SARS-CoV-2 infection and vaccination.

Materials and Methods:

In this study, anti-SARS-CoV-2 spike protein antibody in 161 RTRs was determined by the chemiluminescent microparticle immunoassay methods, and HLA alleles were determined by the polymerase chain reaction-single-strand oligonucleotide methods and analyzed to study the HLA allele association with anti-SARS-CoV-2 spike protein-specific humoral response and severity of COVID-19 symptoms in recently SARS-CoV-2-infected RTRs.

Results:

The anti-SARS-CoV-2 spike protein specific antibody seroconversion rate in RTRs was 90.06% with a median titer of 751.80 AU/ml. The HLA class I alleles, A*11 in 22.1%, A*24 in 21.37%, A*33 in 20.68%, HLA B*15 in 11%, B*07 in 8.27%, HLA-C*30 in 20.93%, C*70 in 23.25% and HLA Class II alleles, DRB1*07 in 18.62%, DRB1*04 in 13.8%, HLA-DRB1*10 in 14.48%, HLA-DQA1*50 in 32.55% of RTRs were associated with the seroconversion. The mean SARS-CoV-2 clearance time was 18.25 ± 8.14 days.

Conclusions:

RTRs with SARS-CoV-2 infection developed a robust seroconversion rate of 90.0% and different alleles of HLA-B, DRB1, and DQA1 were significantly associated with the seroconversion.
Amphotericin B-Resistant Disseminated Cryptococcal Infection with Concurrent Cytomegalovirus Colitis in a Renal Transplant Recipient - A Case Report
Authors: Gaur Mragank , Sethi Jasmine , Prakash Mahesh
Published: December 2022

Post renal transplant opportunistic infections always pose a challenge to the clinician due to the varied nonspecific clinical manifestations and prove fatal if not diagnosed and treated early. Here, we present a case report of a patient who was 22 years post renal transplantation with amphotericin-resistant disseminated cryptococcal infection concurrent with cytomegalovirus colitis treated successfully with oral fluconazole and ganciclovir. The clinician should always take into account the antibiotic susceptibility and culture sensitivity of cryptococcosis to diagnose this rare yet emerging phenomenon of azole resistance. Furthermore, to the best of our knowledge, this is the first reported case of amphotericin-resistant cryptococcosis in posttransplant setting.

Authors: Nerli Rajendra B. , Chandra Shoubhik , Ghagane Shridhar C. , Dixit Neeraj S. , Muzumdar Ameya , Donkar Parveen
Published: December 2022

Comprehensive preoperative evaluation of potential donors is crucial for selecting the right donor. Early segmentary arterial branching is present in 10%–12% of cases. Expert surgeons require at least 1 cm of main donor renal artery to clamp and properly anastomose the artery in the recipient. We report a case of live-related renal transplantation wherein the recipient had a crossed renal ectopia and the donor had early branching of the left renal artery (<5 mm from the aorta).
Unmasking of Immunoglobulin a Deposits Posttransplant due to COVID-19 AKI-Incidental or Causal – A Nephrologists' Dilemma a Case Report
Authors: Dogra Luvdeep , Sahay Manisha , Ismal Kiranmai , Vali P. S.
Published: December 2022

COVID-19 is a global pandemic with the chronically immunosuppressed transplant recipients being the most vulnerable both to infection as well as complications of COVID-19. Here, we report a case of live-related renal allograft recipient who presented with complaints of loose stools and new-onset graft dysfunction 2 years posttransplant. He tested positive for COVID-19 infection. On allograft biopsy, there were significant immunoglobulin A (IgA) deposits with no evidence of rejection or ATN or crescents or significant chronicity. The initial pretransplant biopsy of the recipient had revealed chronic glomerulonephritis with nil deposits. The donor had no evidence of hematuria or hypertension and had a preserved GFR. We, therefore, considered the possibility of the unmasking of IgA deposits posttransplantation diagnosed in a recipient with COVID-19 infection.

Published: December 2022

Introduction:

Metastatic vertebral fractures (VF) commonly cause severe disabling pain in cancer patients

.

VFs are common among elderly patients and account for approximately 1.5 million per year in the general population.

Objective:

Bone metastasis, which is a second major cause of pathologic fracture, may lead to severe intolerable pain, life-threatening hypercalcemia, spinal cord compression, and immobility. The purpose of this study was to evaluate pain relief and improvement in quality of life (QOL) in patients with metastatic VF undergoing percutaneous vertebroplasty (PVP).

Methods:

Ten cancer patients having metastatic VF underwent PVP from July 2018 to August 2020. All demographic data, procedures, improvement in pain, and analgesic requirements of patients were taken from a computer data system and telephonic follow-up.

Results:

Majority of patients were suffering from carcinoma lung followed by carcinoma pancreas. The mean ± standard deviation of Visual Analog Scale preoperatively was 8.8 ± 1.35, reduced to 2.14 ± 2.11 at 6 months postoperatively, suggesting significant pain reduction. Eight patients had reduction in analgesic requirements and two did not require any analgesics postoperatively. During the entire follow-up, there was no delayed complication.

Conclusion:

PVP is an effective, safe, and minimally invasive procedure for treating painful metastatic vertebral compression fracture refractory to conservative treatments. It provides a marked reduction of pain, maintains mechanical stability of the vertebrae, and improves QOL.
Botulinum Toxin Application in Erector Spinae Blockade for the Management of Myofascial Syndrome in Patients with Fibromyalgia
Authors: Rangel J. German W , Ortega A. Karina A , Cediel C. Ximena J
Published: December 2022

Botulinum toxin (BoNT) is a type of bacterial exotoxin that has been included in medical practice for multiple purposes, one of which is pain management. Some of the proposed mechanisms state that BoNT can reduce neurogenic inflammation by blocking the discharge of neuropeptides, including substance P and calcitonin gene-related peptides. Here, we present three patients with myofascial syndrome and fibromyalgia whose main symptom was pain in the dorsal region, wherein BoNT administered in the erector spinae bilaterally provided prolonged pain relief.
Analyses of N-Terminal Pro-Brain Natriuretic Peptide, Cardiac Troponin T, and Creatine Kinase MB in Pericardial Fluid in Sudden Cardiac Death Caused by Ischemic Heart Disease
Authors: Cao Zhipeng , Wang Tianqi , Wu Shao-Huang , Liao Zihan , Zhu Baoli , Zhao Rui
Published: December 2022

Background:

Biochemical analyses of N-terminal pro-brain natriuretic peptide (NT-proBNP), cardiac troponin T (cTnT), and creatine kinase MB (CK-MB) have been reported to be valuable for the auxiliary diagnosis of sudden cardiac death (SCD) in previous forensic studies.

Aims and Objectives:

The present study aimed to evaluate the diagnostic efficiency of combined analyses of NT-proBNP, cTnT and CK-MB in the pericardial fluid for forensic diagnosis of SCD caused by ischemic heart disease.

Materials and Methods:

Levels of NT-proBNP, cTnT, and CK-MB in the pericardial fluid of 132 medicolegal autopsy cases were obtained through electrochemiluminescence method.

Results:

NT-proBNP, cTnT, and CK-MB levels were significantly elevated in SCD cases (P < 0.05). Receiver-operating characteristics (ROC) analysis showed that NT-proBNP, cTnT, and CK-MB have diagnostic value for the diagnosis of SCD: NT-proBNP, cutoff value of 2236 pg/ml; cTnT, cutoff value of 199.51 ng/ml; CK-MB: cutoff value of 2742.5 ng/ml, and the combined analyses of these three biomarkers have better diagnostic efficiency than each single biomarker alone. Moreover, the causes of SCD were sub-divided into acute ischemic heart disease, acute myocardial infarction (AMI), and recurrent myocardial infarction subgroups for further analysis, which revealed that the ratio of cTnT/CK-MB could be used to distinguish AMI with the cutoff value of 0.1085 estimated by ROC analysis.

Conclusion:

These observations suggested that the postmortem biochemical analyses of NT-proBNP, cTnT, and CK-MB in the pericardial fluid may assist to diagnose SCD in forensic practice, and the combined analyses of multiple biomarkers have better diagnostic efficiency than each single biomarker alone. On the basis of the postmortem biochemical analyses of NT-proBNP, cTnT and CK-MB, combining the ratio of cTnT/CK-MB could be used to distinguish AMI.

Authors: Singh Shailendra , Yadav Punit , Goel Akhil , Ahuja Nitin
Published: December 2022

Aims:

The aim of this study was to determine the incidence of central line-associated bloodstream infections (CLABSIs) in the medical and surgical intensive care units (ICUs) of a tertiary care hospital.

Materials and Methods:

One hundred and twenty patients admitted to medical and surgical ICU with an indwelling, nontunneled central venous catheter (CVC) inserted at admission in the department of emergency medicine or at medical and surgical ICU for more than 48 h were monitored. The patients were followed up daily for the development of new-onset sepsis after 48 h of insertion of CVC, by analyzing the culture of two sets of blood samples, over a span of 24 h. The data were evaluated statistically using Microsoft Excel version 11 and SPSS version 17 (IBM, USA).

Results:

Among 120 patients hospitalized for an aggregate of 972 days, 7 patients had acquired CLABSI with an incidence rate of 7.2/1000 central line days. The organisms isolated were Staphylococcus aureus, Acinetobacter spp., Pseudomonas aeruginosa, and Klebsiella pneumoniae.

Conclusion:

The incidence rate of CLABSI in this study was in line with other studies on the CLABSI rate in India. The study found a significant association of CLABSI with duration of CVC catheterization, underlying comorbid conditions and diseases of patients, and indication of CVC insertion. However, there was no significant association of CLABSI with age of patients, their gender, and site of insertion.

Authors: Kubalová Klaudia
Published: December 2022

Mäkké ciele predstavujú pomerne jednoduchý a často vyhľadávaný terč teroristov, prípadne páchateľov trestnej činnosti. K takýmto objektom, resp. priestorom radíme okrem iných železničnú infraštruktúru. Železničné stanice sú verejné priestory, v ktorých sa koncentruje vysoký počet osôb, a ktoré nie sú dostatočne zabezpečené. Z analýzy vybranej železničnej stanice bolo zistené, že najčastejšími trestnými činmi sú krádeže, vandalizmus a pod. Práve voči takýmto hrozbám existuje novodobý preventívny prostriedok, ktorým je koncepcia CPTED (Crime prevention through environmental design). Predmetná koncepcia predstavuje prevenciu kriminality prostredníctvom dispozičného riešenia objektov, resp. priestorov. Implementáciou koncepcie CPTED vieme do istej miery redukovať kriminalitu, ale aj zlepšiť vizuálnu stránku priestorov.

Authors: Šimeček Michal
Published: December 2022

Tento text předkládá výsledky průzkumu uživatelů městské hromadné dopravy v České republice, který se zaměřoval na hodnocení důležitosti vlastností zastávkových stanovišť městské veřejné dopravy a na důležitost různých charakteristik jízdy MHD. Obecně patří mezi nejvýše hodnocené položky ty, které se týkají čistoty, pohodlí a bezpečí. To platí jak pro zastávková stanoviště, tak i pro jízdu MHD. Tyto vlastnosti jsou důležitější pro respondenty s rostoucím věkem a vzděláním. Dále jsou mezi důležitými vlastnostmi také ty, které přispívají k efektivitě využívání MHD (spolehlivost dopravy, informovanost cestujících a možnost volby mezi spoji). Například informační tabule s aktuálními odjezdy jsou důležitější především pro starší dospělé, seniory a studenty, studenti navíc ocení také mobilní aplikaci s těmito údaji. Položky v obou inventářích a především ty, které jsou hodnoceny obecně nejvýše, nejsou tolik důležité pro respondenty, kteří MHD používají často. Pro tyto cestující je důležitá především efektivita městské hromadné dopravy, tedy celkový čas cestování. Mezi položkami, které jsou celkově hodnoceny jako méně důležité figurují položky, které se týkají bezbariérového přístupu na zastávku nebo do vozidla MHD. Tyto vlastnosti jsou však podstatně důležitější pro specifické skupiny respondentů, kterými jsou senioři, respondenti s malými dětmi a nepracující důchodci.
DETERMINATION OF THE OCTANE NUMBER OF AUTOMOTIVE GASOLINES BY FTIR SPECTROMETRY WITH CHEMOMETRICS
Authors: Hurtová Ivana , Sejkorová Marie
Published: December 2022

The quality of motor fuels is more and more strictly controlled in connection with many factors - users are particularly interested in the anti-knock resistance of automotive gasolines, quantitatively expressed by the value of the research octane number (RON). The paper presents FTIR spectrometry in conjunction with chemometry as an alternative method to the standardized determination of the octane number of gasoline by a research method according to ČSN EN ISO 5164. An FTIR-PLS regression model working with spectra in the range of 650–4000 cm-1 was proposed for ON prediction. With this model, a very strong dependence (R=0.996) was achieved between the predicted of octane number values and the values determined by the standardized method; the calibration error was 0.414.

Rusya'nın Ukrayna İşgalinin Avrupa Mülteci Mevzuatı ve Ukraynalı Mülteciler Üzerindeki Hukuksal Etkisi
Authors: BAKIR Hakim
Published: December 2022

Coğrafi konumu gereği Rusya-Avrupa arasında stratejik bir öneme sahip olan ve 46 milyon nüfusun yaklaşık %22 Rus olan Ukrayna 1991 yıllında bağımsızlığını ilan etmiştir. Ukrayna’nın 2004 yılında itibaren NATO ve Avrupa Birliği’ne yakın siyaset izlemesi Rusya tarafında sert bir tepkiyle karşılanmıştır. Bu rağmen iki ülke ekonomik ilişkilerini devam ettirmiş ve Rus doğalgazının Avrupa’ya transferi Ukrayna üzerinden sağlanmıştır. 2014 yılında ise Rusya, tarihi ve stratejik bir öneme sahip olan Kırım’ı ilhak etmesi Ukrayna’ya yönelik ilk işgali kabul edilmiş ve 921.000'den fazla kişi yerinden edilmiştir. Yakın dönemde de ise Rusya devlet başkanı Vladimir Putin savaş yanlısı politika izlemesi Şubat 2022’de büyük bir savaşın yaşanmasına neden olmuştur. Ukrayna Cumhurbaşkanı Volodimir Oleksandroviç Zelenski ise savaşın çıkmaması için büyük uğraşlar vermiş ve savaş başladıktan sonra ise ülkede kaçmak yerine kalıp direnmeyi seçmiştir.

Birleşmiş Milletler Mülteciler Yüksek Komiserliği’ne göre 24 Şubat 2022’den 4 Ekim 2022 tarihine kadar toplam 13,736,198 Ukraynalı savaş nedeniyle yerinden edilmiş ve Avrupa kıtasında mülteci olmuştur. Avrupa kıtası bu savaş ile II. Dünya Savaşı’ndan beri en büyük mülteci krizine maruz kalmıştır. Avrupa Birliği’ne üye devletlere sığınan Ukraynalı mülteciler Avrupa Birliği tarafından 4 Mart 2022 yılında kabul edilen geçici koruma kapsamında değerlendirilirken diğer ülkelere göç edenler Ukraynalılar ise 1951 Cenevre Mülteci Sözleşmesi kapsamında mülteci olarak kabul edilmiştir. Ukrayna krizi aynı zamanda da küresel iş birliğinin ve 1951 Mültecilerin Statüsüne İlişkin Sözleşme’nin kitlesel mülteci krizlerine cevap vermekten de ne kadar yetersiz olduğunu göstermiştir.

Published: December 2022

The relocation of the capital city of Indonesia in Panajam had an impact on the Paser ethnicity the original ethnicity that inhabited the location. These ethnic groups experience a pattern of subalternity relations, such as their residential land and livelihoods being suddenly set, not being involved in decision-making processes, being prohibited from accessing the zero point, and not given space to become local workers in the work of the National Capital development project. This pattern of subalternity relations then developed into a communal identity as the spirit of this community to carry out emancipatory struggles. Aim this research is explore social dinamics of Paser Community Survival as subaltern group in the IKN project. The research method used is a qualitative method with data collection in the form of interviews, FGDs, and participatory observations. The data were analyzed by finding meaning patterns/themes and presented narratively. The results of the study found the social dynamics of resilience and sustainability through social dialogue, advocacy communication, network mobilization, use of social media, and cultural movements. This research concludes that the dynamics of survival and survival are pursued through advocacy dialogue to gain capacity building and recognition of Paser culture. It is hoped that this community needs to build mutual awareness to continue the struggle for its existence through community empowerment efforts in the form of capacity building.
Mercantilización de las Áreas Naturales Protegidas y Gentrificación verde metropolitana. El caso de la ciudad de Querétaro, México
Authors: Bonfil Jiménez Úrsula , Ribeiro Palacios Mónica
Published: December 2022

En los últimos 25 años las ciudades medias y pequeñas del sur global han experimentado un acelerado crecimiento metropolitano. Esta expansión territorial en áreas periurbanas ha impulsado un nuevo modelo de desarrollo inmobiliario vinculado a la naturaleza y volcado a las clases altas. Por ello, las áreas naturales protegidas (ANPs) ubicadas en la periferia urbana entran en una lógica de mercado, contribuyendo a la concentración de valor entorno a ellas. En este escenario, es necesario entender el papel de los instrumentos de ordenamiento territorial, en la consolidación de ciertos desarrollos inmobiliario y los procesos de segregación espacial alrededor de las ANPs. Presentamos el caso de la Zona Metropolitana de la ciudad de Querétaro ubicada en el centro de México. A partir de métodos cualitativos identificamos las contradicciones en la materialización de los instrumentos de ordenamiento territorial y planeación urbana, asociados a las ANPs, los discursos publicitarios de los nuevos proyectos inmobiliarios ubicados en los alrededores de las ANPs y la reconfiguración territorial y gentrificación verde que se detona a la llegada de nuevos fraccionamientos en las tierras aledañas a las ANPs. Encontramos que la toma de decisiones sobre el ordenamiento territorial y planeación urbana está centrada en las autoridades locales, lo que permite implementar arreglos institucionales que favorecen la mercantilización de las ANPs. Las inmobiliarias han construido un discurso donde las ANPs se conciben como un bien inmueble, destinado a quienes tiene la capacidad de pagar por su disfrute, a expensas de las poblaciones campesinas que ahí habitaban.

El Bono de Desarrollo Humano constituye un programa de transferencias monetarias condicionadas direccionado a combatir la pobreza y pobreza extrema, puesta en marcha desde 1998 en Ecuador. En este contexto, el objetivo de este artículo es realizar una descripción de la condición socioeconómica de los beneficiarios del Bono de Desarrollo Humano, y discutir cuál ha sido su aporte en el mejoramiento del nivel de vida de las familias de bajos recursos. Para ello se realizó un estudio exploratorio descriptivo, utilizando como instrumento de recolección de datos una encuesta aplicada a una muestra de 195 beneficiarios del Bono de Desarrollo Humano, de la parroquia urbana El Valle, del cantón Loja en Ecuador. Los resultados muestran que el 34,4 % de los beneficiarios del BDH son madres de familia entre los 26 y 35 años, que tienen hasta 3 cargas familiares y han aprobado solamente el nivel de educación primario. Igualmente, se determinó que los beneficiarios ocupan este ingreso para pagar: servicios básicos, alimentos y arriendo. En general, los gastos superan a los ingresos, por lo que la situación de pobreza no logra superarse.

Darle voz a la violencia más silenciada. Experiencias de sufrimiento de activistas críticas de la violencia obstétrica en Buenos Aires
Authors: Jerez Celeste
Published: December 2022

En Buenos Aires, Argentina, los activismos de mujeres cumplieron un rol fundamental en la consolidación de los derechos reproductivos, específicamente, de las leyes de parto humanizado y violencia obstétrica. Aunque no han sido reconocidas públicamente, las activistas fueron pioneras en alzar la voz y pujar por darle sentido al término. Ellas politizaron su propia experiencia de sufrimiento durante la atención del parto al nombrarla violencia obstétrica, modalidad de la violencia de género. Es más, se reconocieron como víctimas e hicieron audible los mandatos de género y las prácticas naturalizadas del sistema de atención: ser tratadas como cuerpo-objetos para la reproducción. Consideramos, pues, a la violencia obstétrica como una categoría epistémica, ambigua y que ha sido disputada políticamente en su significado por distintos actores sociales. Como objetivo principal se analizan –en clave de género y feminista- los modos en los que el sufrimiento durante el parto de las activistas fue reconocido por ellas mismas como violencia obstétrica junto a otras mujeres y se transformó en una herramienta política con alcances comunitarios. Para ello, el método etnográfico, como metodología cualitativa, permite ahondar en las reflexividades implicadas como acercamiento a lo social, a las relaciones de poder y a la cotidianidad íntima de los actores. Así, sus testimonios sobre la violencia obstétrica fueron una puerta de entrada al desarrollo de redes políticas y militancia sobre el tema. Ellas tuvieron un rol protagónico en la disputa moral por el sentido de la violencia obstétrica, en la que sus corporalidades jugaron un rol central.

Published: December 2022

Bamboo shoots form an integral part of the local diet of the Northeastern states of India. Fermented shoots have been consumed by tribal communities since ancient times. However, with increasing globalization and fast-food consumption, the traditional knowledge and skills of processing bamboo shoots seem to be changing. This paper highlights the changes in processing ways over the years in the younger generation. Data were collected using an unstructured interview schedule and observation through home visits from Adi women of four villages namely Balek, Sibut, Runne, and Mirbuk in Pasighat Block of Arunachal Pradesh. It was observed that some newer practices of processing bamboo shoots had been adopted while ignoring the traditional practices which emphasized eliminating toxicity in bamboo shoots.

Desde el inicio de la pandemia, en Marzo 2020, la actividad asistencial se vio afectada. El Hospital Español de Buenos Aires comenzó a ser centro de derivación de AMBA para pacientes SAR COV2 PAMI, alcanzando un alto grado de saturación de ocupación de camas. Por este motivo se suspendió la actividad quirúrgica programada, interviniéndose sólo pacientes de urgencia y oncológicos. Se suspendieron los consultorios externos y turnos para endoscopias y estudios imagenológicos, provocando no solo un retraso en el diagnóstico de los pacientes con CCR, para screening y estadificación, sino también el tratamiento quirúrgico de los mismos.

De ahí la importancia de analizar el impacto de la pandemia en el tratamiento quirúrgico del cáncer colorrectal en nuestra institución.

Authors: Oloye Abraham O. , Olalusi Ayoola P. , Falayi Fola R.
Published: December 2022

Yam tuber (Dioscorea spp.) is a staple tropical tuber crop that is usually best eaten in its fresh form. However, inadequate preservation and storage can result in yam tubers deterioration immediately after harvesting due to their relatively high moisture content. All the traditional structures of preserving and storing yam tubers could not maintain their freshness for a long time. Therefore, the need for developing a new storage structure for the preservation of farm produce is needed. The major components of the cold storage structure are the frame, compressor, condenser, capillary tube, and evaporator. It would be fabricated with angle iron, galvanized mild steel, and stainless steel and insulated with 0.025 m thick polystyrene foam with the cooling system operating with R134a fluid. The total storage space was 0.2 m3 and it can store 100 kg of tubers of yam.  The total heat load, compressor capacity, condenser capacity, and evaporator capacity were 0.204 kW, 0.46 kW, 1.6059 kW, and 1.37931 kW respectively. The structure has the prospect of being used for the preservation and storage of yam tubers and will be very useful in a developing economy like Nigeria.
Stochastic Simulation Modelling and Analysis of Out-Patient flow: A Case Study of General Hospital Hadejia, North-western Nigeria
Authors: Abubakar Maji I.
Published: December 2022

Increasing demand for health care coupled with resource constraints may lead to overcrowding in health care center. Generally, patient flow into health care center is characterized by variability due to its stochastic behavior. In recent years, there has been increasing interest in Discrete Event Simulation (DES) technique in healthcare systems due to its sensitivity to systems’ variability. Discrete Event Simulation (DES) technique is used in this study to examine patient flow in an urban health care center, the General Hospital Hadejia (GHH), with a view to analyzing resource utilization, minimizing waiting time, and improving efficiency and effectiveness. Data relating to waiting time, service time, and movements of patients between departments within the health center were collected and analyzed. The influence of operational policies on the efficient movement of patients during peak and off-peak demand periods is studied. Results of the discrete event simulation experiment show an average increase of 41% of patients’ visits to the hospital when the existing layout of the hospital is modified.

Authors: Adebayo Bosede O. , Olatunde Nathaniel A.
Published: December 2022

Construction projects are greatly affected by endogenous and exogenous risk factors. The purpose of this study is to investigate risk factors with high levels of occurrence and their impacts on project goals. These will help in finding the most appropriate mitigating strategy used by contractors on educational building projects with a view to enhance performance and reduce cost. A convenience sampling method was used to select 3 professionals each from 44 contracting firms working in the Educational building construction projects in Ekiti State, Nigeria. Forty-eight risk factors were identified through a review of literature. Data was collected through a structured survey and the data was analysed using Mann-Whitney U-test, Mean item score and frequencies.  The results showed that inadequate funding by the client, the financial instability of contractors and suppliers, fluctuations in market price and inflation (all finance related) are the most critical risk factors in terms of the level of occurrence and impact. These factors had a great effect on project success. The study highlights risk factors that are capable of causing negative effects on the success of educational building projects. It also helps to solve the problems associated with the handling of risk by contracting firms. The study will be of value to stakeholders in providing the information needed to devise response strategies to minimise the impact of a risk on projects.

Politeknik Industri ATMI is a vocational education institution that beside carrying out the educational process, ATMI has a production division that aims to carry out order-based production in order to increase the income for education funds. The products produced are custom products ordered by customers which have different process variations. The object of the research is the production processed in the lathe and milling practical section. The percentage of defective products in this division in the period January 2022 - October 2022 reach 8% higher than the specified procentage, which should not exceed 5% defects form the products produced. Problems related to product quality lead to increase production operational costs as a result of repeat production process or rework. This activity can cause loss of customers due to disappointment over poor product results. This research activity was carried out to find problems in product defects, find the root of the problem and propose improvements. All possibilities that affecting Product defects are evaluated using an affinity diagram which produces 5 parts that can be the cause of defects, namely: Humans, Materials, Processes, Equipment and Systems. These results explore further the relationship between one another using an interrelationship diagram. Tree diagrams are used to obtain factors that can be used as suggestions for improvements to the corrections of problems found. The improvement to the corrections suggestions are: Recruiting competent employees; Employee training / training; Implementation of inherent quality control; Application of SOP in production; Making clear job descriptions; Implementation of 5R and K3; Routine machine maintenance. Using a complete matrix diagram with the analysis carried out, it is obtained a sequence of possible improvements to be made in order to improve quality, namely the first is the application of inherent quality control; the second order is the application of SOP in production; third is the implementation of 5R and K3; fourth is recruiting competent employees, employee training / training or routine machine maintenance; fifth is making a clear job description.

Authors: ÇAM YANIK Tuğba , ALTUN UĞRAŞ Gülay
Published: December 2022

Amaç: Bu araştırma, COVID-19 pandemisinde kendi kendine uygulanan akupresürün cerrahi hemşirelerinin uyku kalitesi ve gündüz uykululuklarına etkisini belirlemek amacıyla planlandı. Örneklem ve Yöntem: Bu çalışma, prospektif, iki kollu (1:1), randomize kontrollü tek kör çalışmadır. Protokolün hazırlanmasında SPIRIT 2013 kontrol listesi ve CONSORT akış şeması kullanılmıştır. Çalışmanın örneklemini, Mart 2021-Haziran 2021 tarihleri arasında Türkiye’de bir üniversite hastanesinin cerrahi kliniklerinde vardiyalı çalışan 60 cerrahi hemşiresi oluşturacaktır. Hemşireler, akupresür (çalışma) ve plasebo akupresür (kontrol) gruplarına randomizasyonla atanacaktır. Akupresür grubuna (n:30) HT7 ve SP6 noktalarına basınç uygulatılırken, plasebo akupresür grubuna (n:30) aynı noktaların 1.5 cm çevresindeki noktalara daha hafif basınç uygulanması sağlanacaktır. Akupresür 4 hafta boyunca haftada 3 kez uyumadan bir saat önce yaptırılacaktır. Araştırmanın primary outcome olan uyku kalitesi Pittsburg Uyku Kalitesi İndeksi (PUKİ) ile; secondary outcome olan gündüz uykululuk durumu ise Epworth Uykululuk Ölçeği (EUÖ) ile değerlendirilecektir. Körlenmiş hemşireler PUKİ ve EUÖ’ni, akupresür/plasebo akupresür öncesi ve sonrası dolduracaktır. Bulgular: COVID-19 pandemisinde çalışan sağlık profesyonellerinin uyku problemleri yaşadığı bilinmektedir. Akupresürün uyku kalitesini arttırdığı bilinmesine karşın pandemide vardiyalı çalışan cerrahi hemşirelerinde etkili olup olmadığı bilinmemektedir. Bu çalışmada cerrahi hemşirelerinin uyku kalitesinin arttırılması ve gündüz uykululuğunun azaltılmasında nonfarmakolojik bir yöntem olan akupresürün etkisinin belirlenmesine yönelik kanıt düzeyi yüksek sonuçlar elde edilmesi beklenmektedir. Sonuç: Çalışma sonuçları, COVID-19 pandemisi gibi sağlık profesyonellerinin aşırı strese maruz kaldıkları dönemde hemşirelerin yaşadıkları uyku sorunlarıyla baş etmesine yardımcı olabilecek ve yeni araştırmalara rehberlik edebilecektir. Kayıt numarası: Bu çalışma ClinicalTrials.gov’a Mart 2021 tarihinde kaydedilmiştir (NCT04800939).
