Background: The critical role of antimicrobial stewardship (AMS) in mitigating antimicrobial resistance cannot be overemphasized, especially during COVID-19 pandemic. This study aimed to understand the perception of physicians about AMS as it relates to their training and practice experience.

Method: A phenomenological qualitative study design was employed, and data was collected using a semi-structured questionnaire-based interview of a purposive sample of practicing physicians in the federal capital territory of Nigeria. Eighteen physicians completed the interview and responded based on their perceptions and practice experience. Thematic analysis and coding of the data were performed through an iterative process.

Results: 56% of the respondents were female physicians, 67% worked in a private hospital/clinic, and 44% have been practicing for 11 – 15 years. 83% of the respondents think auditing clinicians would promote antibiotics stewardship. 44% of the respondents were unaware of clinical guidelines for an empirical antibiotics prescription. 56% felt doctors were not provided thorough training on AMS. The participants suggest that AMS in Nigeria could be promoted through training of personnel, establishing antibiotics policy and protocol, cessation of over-the-counter sales of antibiotics, creating awareness, access to prompt laboratory investigation and inter-professional collaboration between physicians and pharmacists. They also believed inter-professional collaboration is necessary to achieve AMS.

Conclusion: Physicians perceived a knowledge gap in AMS as a result of inadequate training and lack of clinical guidelines on antimicrobial stewardship in the healthcare system of Nigeria. Intensive education of healthcare providers and inter-professional collaboration are plausible approaches to improving antibiotic stewardship.
Review: JAK2V617F Allele Burden in Diagnosis and Therapeutic Monitoring of Myeloproliferative Neoplasms
Authors: Dharmawickreme Bhagya , Witharana Chamindri
Published: March 2023

Characterized by overproduction of differentiated cells of myeloid lineage, polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF) are Philadelphia chromosome negative myeloproliferative neoplasms (MPNs). Found in 95% of PV patients and 50-60% of ET and PMF patients, the JAK2V617F mutation is the most common molecular abnormality shared by the three MPN phenotypes. Although the JAK2 mutation is recommended for diagnosis of MPNs by the World Health Organization (WHO), its presence alone is insufficient to discriminate among the 3 subtypes. This implication of single mutation (JAK2V617F) in all three MPN phenotypes has long been an objective under question and several studies investigating on the gene dosage hypothesis have discovered the promising role of the JAK2V617F allele burden in MPN phenotype. The significant differences of the JAK2V617F allele burden in PV, ET and PMF patients as well its associations with specific clinical and haematological characteristics bear high utility in diagnosis, prognosis, and therapeutic monitoring. Although great strides have been achieved with the use of qPCR and new molecular biology techniques in allele burden quantification, addressing the deficits in the current understandings and further improvement of technology will be highly beneficial. Therefore, we have reviewed PubMed database from 2005 to 2022.
Using keywords such as JAK2V617F mutation, Allele burden, Myeloproliferative neoplasms etc. and the present review discusses the significance of JAK2V617F allele burden in diagnosis and therapeutic monitoring of myeloproliferative neoplasms.
Nevoid Basal Cell Carcinoma Syndrome: A Review
Authors: Binsheikhan Saleh , Mittal Saurabh , Al Abadie Mohammed
Published: March 2023

Introduction: Gorlin syndrome (GS) or nevoid basal cell carcinoma syndrome (NBCCS) is a rare genetic disorder characterised by development of multiple basal cell carcinomas (BCCs) at a young age.  NBCCS occurs because of mutations in the PTCH1 gene, which functions as a tumour suppressor gene.

Patients with GS can have varied manifestations, both cutaneous and extra-cutaneous.  The most notable cutaneous manifestations are BCCs, which are also the most characteristic tumours in GS, and palmar/plantar pits.  Besides the BCC, medulloblastomas are the second most characteristic malignant presentation.

There are a set of criteria for the diagnosis of GS, which have a high predictability in making an accurate diagnosis of GS.  Genetic testing for PTCH1 gene is one of the diagnostic criteria, which is positive in about 60% of patients.

Patients with GS need a multidisciplinary approach.  Mohs micrographic surgery is recommended for BCCs on high risk areas.  SMO receptor inhibitors such as Vismodegib and Sonidegib have been approved by FDA for the treatment of advanced BCCs.
Does Posterior Stabilized Better than Posterior Cruciate Retaining in Total Knee Replacement? A Systematic Review and Meta-analysis
Authors: Wiradiputra Agus Eka , Dharmayuda Cokorda Gde Oka , Febyan
Published: March 2023

This meta-analysis aimed to compare the results of posterior stabilized and posterior cruciate-retaining prosthesis. To find randomized controlled studies comparing the clinical outcomes of cruciate-retaining and posterior-stabilized systems, a computerized literature search was performed. To find more pertinent studies, the table of contents of four significant orthopaedic journals and the references part of two arthroplasty text books were examined. Finally, 1114 individuals' knees totaling 1265 were compared. A statistical analysis showed that posterior-stabilized knees had significantly greater flexion and range of motion, but no change in complication rates. This's clinical significance is still unknown. The surgeon's preference and comfort level with a particular design should determine which design is used.
Laminoplasty Versus Laminectomy and Fusion in the Surgery Approach for Multilevel Cervical Spondylotic Myelopathy: A Current Perspective and Meta-Analysis
Authors: Putra I Gusti Ngurah Paramartha Wijaya , Febyan
Published: March 2023

Background: Cervical spondylotic myelopathy (CSM) is a clinical disease which characterized by degeneration of the intervertebral discs and nearby spinal structures. The goal of this study is to compare laminoplasty (LP) versus laminectomy and fusion (LF) for multilevel cervical spondylotic myelopathy (CSM) in terms of clinical safety and effectiveness.

Methods: This study is a meta-analysis from randomized and non-randomized control study. The database being used were PubMed, Google Scholar, Cochrane Registry, and Embase. The authors extensively searched the relevant papers comparing the clinical efficacy and safety of LF and LP for the therapy of multilayer CSM. The outcome measures recorded were visual analog scale (VAS), cervical curvature index (CCI), The Japanese Orthopaedic Association (JOA) scores, Nurich grade, reoperation rate, complications, and rate of nerve palsies. The analysis were performed by using RevMan 5.3.

Results: Our meta-analysis includes a total of 14 papers. The pooled mean difference between LF and LP was insignificant in terms of VAS of neck pain (p=0.54), post-operative CCI (p=0.24), JOA score (p=0.29), Nurich grade (p=0.16) and reoperation rate (p=0.21). The complication and nerve palsies rate was higher in LF group compared to LP group (OR 2.60, 95% CI 1.85, 3.64, I2=26%, P < .00001) and (OR 3.18, 95% CI 1.66, 6.11, I2=47%, P=.0005) respectively.               

Conclusion: Our meta-analysis demonstrates that the majority of clinical outcomes for surgical treatments of multilevel CSM utilizing LF and LP are comparable. However, it was discovered that LP was superior compared to LF in terms of nerve palsy rate. This needs additional validation and research in more extensive sample-size and randomized studies.
Ethical issues in geriatric care

Published: March 2023

Increased life expectancy along with an increasing share of elderly and senile patients in the structure of the population make the tasks of longer healthy life expectancy pressing. A set of activities aimed at optimization of management of patients within the framework of gerontological practice should include elimination and prevention of diagnostic and therapeutic errors. The basic risk factors of medical errors include high heterogeneity of elderly and senile patients, overburdened healthcare system, polypharmacy, including due to parallel prescription of drugs to the same patient by multiple medical professionals, concomitant diseases, and high comorbidity, measured by the Charlson Comorbidity Index. Mismanagement of elderly patients can result both from underestimated severity of the patient’s conditions, and from hyperdiagnostics. Typical errors of pharmacotherapy include use of potentially inappropriate medications, potential prescribing omissions, simultaneous prescription of drugs with high risk of clinically significant interactions, incorrect selection of dosage without taking into account the renal failure, which is associated with high risk of toxic effects. Affordability of medical aid for an elderly patient is another important social aspect influencing the patient’s quality of life. As far as basic ethical principles of management of elderly and senile patients go, it is necessary to respect independence, well-being and justice for the patients regarding possible obtaining of qualitative medical aid as compared with other age groups.

Authors: Alaa Ismael Mays , Gh. Yahya Samir , Azhar Md. , Mahbubul I.M. , Ilori Olusegun
Published: March 2023

A conventional vapor compression refrigeration cycle is among the most effective technology in refrigeration systems. In the present experimental study, thermal performance and the effect of the condenser temperature have been analyzed. With the decrease in the condenser temperature, the overall performance of the refrigeration cycle is increased. However, the cooling power and efficiency of conventional vapor pressure air conditioning units can experience a significant reduction when operating in extreme weather (hot and dry). This drop is mainly affected by the increase in the temperature (and pressure) of the condenser with an increase in the ambient air temperature. Unfortunately, Iraq experiences the most extreme summer seasons especially in the months of June and July when the temperature reaches or exceeds 50° C. So, ground cooling has been used in areas with a hot environment for split system air conditioners. Evaporative cooling was also performed to lower the coolant temperature of the AC unit used inside the condenser area. Experimental results showed that when using a geothermal heat exchanger, the temperature of the condenser is reduced from 116 to 110 ° C and the coefficient of performance (COP) is improved by 41%. In addition to this when the system uses evaporative cooling the temperature of the condenser is reduced from 110 ° C to 88° C. Moreover, a 65% improvement was made in the COP of the conventional vapor compression refrigeration cycle. Furthermore, with a decrease in the evaporator temperature from 6 to 3.5 °C there was an increase in refrigeration capacity by an average of 52%.

Authors: Arief Ria Qadariah , Sarih Karmila , Mahmud Nur Ulmy
Published: March 2023

Birth weight is an essential indicator in assessing a baby's health and a factor that affects the baby's long-term health. This study aimed to determine the relationship between the Body Mass Index (BMI), Hemoglobin levels, and Blood Pressure of mothers during pregnancy and to birth weight of the baby. The study used a cross-sectional survey of a group of mothers who gave birth in Makassar. The data on mothers during pregnancy was the maternal history recorded in the mother and Child Health Book (KIA). And the data on the birth weight of the baby was also from the KIA book with the support of secondary data from the Community Health Center and Midwife. The results showed that 41.7% of the low-birth-weight babies had mothers who experienced underweight during pregnancy, 83.3% of the low-birth-weight babies had mothers who experienced Anemia during pregnancy, and 66.7% of the low-birth-weight babies had mothers who experienced hypertension during pregnancy. There was a significant and close relationship between the mother's BMI, Hemoglobin levels, and Blood Pressure to the baby's birth weight. There was a meaningful relationship between the mother's Body Mass Index, Anemia, and Hypertension during pregnancy to low birth weight. Therefore, it is important to maintain a good quality of nutrition for mothers both before and during pregnancy, following Islamic teachings that Allah SWT has decreed for every pregnant woman a thousand good deeds every day and erases a thousand misdeeds as motivation to remain strong throughout the pregnancy process.
Modern Dishes: How Are They Named and What Do They Tell Us about Culinary Trends?
Authors: Son Phan Ngoc
Published: March 2023

This research aims to uncover linguistic and cultural features in dish names, also known as culinaronyms. The purpose of this study is to show how the culinaronym is structured, specifically to examine the link between the components of the name and its semantic diversification within the word. Additionally, this study will identify the characteristics of the culinary trends of an ethnic group based on the dishes of that language. The results exhibit that culinaronyms are created by linking, recreating, adding, and rotating its components. In addition, the modern culinary trend is gradually synching with the trend of developing life, the need for healthy living and the promotion of traditional values, combined with modern factors. The prospect that the topic will contribute to the study of culinary language, especially within the field of identifiers, is the idea that it will create a foundation for the study of culinary culture based on the linguistic features of dish names, and food of one nation or another.
What Jokes Can Tell: A Top 5 of Ethical Transgressions in Consulting
Authors: Bouwmeester Onno
Published: March 2023

In studies on consultant ethics clients are usually portrayed as their potential victims. However, in newspapers a different story can be found, when journalists report cased where clients and consultants have been partners in crime. To better map the common ethical transgressions in consulting, this study presents a top five based on interviews with consultants. In addition, the study illustrates these common transgressions with public jokes, found on the internet. The findings show how clients are not the only, and certainly not the most vulnerable stakeholder. Client interests are relatively well acknowledged in consultancies’ codes of conduct, and much more so than for example those of client staff, or junior consultants. This study contributes to consultant practice by emphasizing how consultant ethics should acknowledge more stakeholders than only clients. Likewise, it flags the issue of consultant independence, as it is consultants second most reported ethical challenge. The study contributes to the business ethics literature by demonstrating the illustrative value of business jokes in pointing at common ethical transgression, complementary to the less common and more severe cases journalists report about.

Las estimaciones de precipitación basadas en satélites representan una valiosa fuente de información alternativa para diferentes aplicaciones hidrológicas, por lo que entender la habilidad de los productos satelitales para capturar la variabilidad espacial y temporal de la precipitación es crucial para el desarrollo de sistemas de monitoreo y alerta hidrometeorológica. En este trabajo se evalúa la confiabilidad de tres productos de precipitación satelital (PPS) en la región pampeana argentina, antes y después de aplicarles el método de corrección de sesgo Quantile Mapping. Los PPS usados son TMPA, CMORPH e IMERG, todos en sus versiones en tiempo casi real. La evaluación se realizó mediante estadísticos categóricos y descriptivos a fin de conocer su capacidad en proporcionar estimaciones confiables y detectar correctamente la magnitud de los eventos. El análisis de los estadísticos categóricos se realizó a nivel diario; en este caso, los PPS estiman mejor las observaciones para intensidades bajas (menores a 5 mm) y medias (entre 5 y 20 mm) que para intensidades altas (mayores a 20 mm). La evaluación de estadísticos descriptivos a nivel mensual mostró que el CMORPH tiene mayor capacidad de detección en los trimestres EFM y AMJ, mientras que el IMERG obtuvo los menores errores para los trimestres JAS y OND. La incorporación de un método de remoción del sesgo en el proceso de validación de los PPS introdujo mejoras significativas en los estadísticos evaluados. Especialmente el CMORPH superó su rendimiento al compararlo con el IMERG, siendo el TMPA el que mayores errores presenta en la región.

Authors:   Universidad Autónoma de San Luis Potosí, San Luis Potosí, México, Campos-Aranda Daniel Francisco
Published: March 2023

La planeación y manejo de los recursos hidráulicos de un río y la elaboración de los planes ―de tipo no estructural― de mitigación de daños causados por sus inundaciones dependen de la relación que guarda el gasto máximo anual con su fecha de ocurrencia. Tales fechas, al acontecer durante el año, pueden ser tratadas como datos circulares, cuyos estadísticos de dirección media y dispersión, o índice de estacionalidad, definen los dos parámetros de ajuste de la distribución de von Mises (dvM), la cual permite la caracterización probabilística de las fechas de ocurrencia de las crecientes anuales; es decir, define su función de distribución de probabilidades. En este estudio se describe la dvM y su método de ajuste por máxima verosimilitud cuando los datos o fechas anuales son unimodales y abarcan todo el año. Cuando las fechas anuales se concentran en una porción del año, la dvM se ajusta con optimización numérica, vía el algoritmo de Rosenbrock. Por último, se describe cómo se representan, con una mezcla de tres dvM, las fechas de ocurrencia que son bimodales, cuyo ajuste, vía optimización numérica restringida, se realizó con el algoritmo Complex. Como un caso de aplicación, se procesaron las fechas de ocurrencia de 777 crecientes anuales registradas en 21 estaciones hidrométricas de la Región Hidrológica No. 10 (Sinaloa), México; se exponen con detalle siete aplicaciones típicas de los tres tipos de ajuste de la dvM. Las conclusiones ratifican a la dvM como modelo probabilístico de las fechas de ocurrencia de las crecientes anuales, sean unimodales o bimodales.

Spatial and temporal changes in water chemistry were evaluated using surface water extracted from a Mediterranean river basin, i.e., The Mataquito River, central Chile. The processes that control water chemistry dynamics in the basin were determined by assessing the relationship between hydrologic events (rainfall, river flow, runoff rates), physical-chemistry properties, and major ion concentrations/distributions along the river. During the rainy period, major ion levels were controlled predominantly by weathering (rainfall). During the dry period, seawater intrusion was the main factor controlling water chemistry. Unusually high chlorine and sulfate concentrations suggested anthropogenic sources of the ions entering the basin. Thus, pollution from industrial and agricultural activities in the basin might be quantitatively important and should be considered in future studies of this area.

La calidad ecológica del agua indica la estabilidad del ecosistema y garantiza su conveniencia de uso. El objetivo fue investigar el índice de calidad del agua (ICA) y la pertinencia de uso de la red hidrográfica del centro-norte de Sinaloa. Se recolectaron 40 muestras de agua superficial de diferentes recursos hídricos (RH): drenes (n = 26), ríos (n = 8) y bahías (n = 6), incluyendo tomas de caudal (agua dulce) y desembocadura (agua salada). Los parámetros fisicoquímicos, nutrientes, metales e indicadores fecales fueron evaluados y comparados con los estándares nacionales bajo un análisis multivariado y de correlación. El ICA se determinó solo en las muestras de caudal. Los RH se diferenciaron por ciertos parámetros fisicoquímicos (pH, CE y SDT), nutrimentales (P y NO3) y microbiológicos (p < 0.05). El análisis multivariado reveló un perfil de contaminación particular al RH: indicadores fecales y nutrimentos se identificaron como factores de riesgo. La concentración fecal en las muestras de agua (65 %) expone el riesgo para la salud (> 200 NMP·100 ml-1), y sus valores muestran correlación con los otros parámetros. El caudal de todos los ríos y mayoría de los drenes (64 %) presentan un ICA “bueno”, que está en línea con su pertinencia para la vida acuática y actividad agrícola, pero no recreacional. Por el contrario, la desembocadura de los RH es pertinente para uso recreativo y acuícola. Nuestros hallazgos evidencian un manejo antrópico similar de los RH y advierten sobre el uso potencial. Además, indican la importancia de restaurar la calidad del agua para reducir las implicaciones ambientales y de salud.

PT. XYZ merupakan perusahaan yang memproduksi kemasan untuk berbagai merk kosmetik dan perawatan tubuh. Dalam pemenuhan tingkat permintaan konsumen, PT. XYZ terkadang melakukan pembelian material dari perusahaan lain yang disebut dengan sistem incoming dan trading. Sebanyak 39 kali frekuensi pembelian produk incoming dan trading tidak memenuhi spesifikasi kualitas pada tahun 2019. Hal inilah yang mendasari tujuan penelitian ini, yaitu menemukan penyebab produk tidak memenuhi spesifikasi dan memberikan upaya perbaikan untuk meningkatkan kualitas dari produk incoming dan trading pada PT XYZ. Penelitian ini menggunakan metode six sigma dengan konsep DMAIC. Dengan menggunakan diagram Pareto diketahui bahwa jenis kecacatan visual dan fungsi menjadi prioritas perbaikan. Selanjutnya perbaikan difokuskan pada penyebab kecacatan dengan nilai RPN terbesar, yaitu jumlah sample tidak sesuai standar yang disebabkan karena terbatasnya waktu untuk melakukan inspeksi. Perbaikan yang dilakukan adalah dengan mengurangi beban kerja operator sebanyak 30%, dengan tujuan agar operator memiliki lebih banyak waktu untuk melakukan inspeksi. Perbaikan yang dilakukan ini berhasil mengurangi beban kerja operator dari 70,04% menjadi 49,55%.
PENGUKURAN KINERJA RANTAI PASOK PADA PT. SIP DENGAN PENDEKATAN SCOR DAN ANALYSIS HIERARCY PROCESS (AHP)

PT SIP adalah sebuah perusahan distribusi baru yang saat ini belum melakukan pengukuran kinerja rantai pasok secara  menyeluruh melainkan hanya satu sisi saja yaitu dari variabel cost. Kendati performa perusahaan berdasarkan cost dikatakan baik (operational cost 4%  dengan target 5% dari total penjualan). Sisi kinerja yang belum menjadi perhatian perusahaan antara lain kecepatan pengiriman, persentase pengiriman produk dan kecepatan pengembalian modal belanja. Penelitian ini menggunakan metode Supply Chain Operation Reference (SCOR) 3 level dengan 4 inti bisnis proses yaitu: plan, source, delivery, dan return. Selain itu penelitian ini juga mengunakan Analytical Hierarchy Process (AHP) untuk menentukan bobot pada tiap-tiap metrik kinerja. Metrik kinerja yang didapatkan dari proses validasi oleh operational kemudian dilakukan perhitungan normalisasi Snorm guna menyamakan pencapaian kinerja saat ini dan menentukan pengukuran menggunakan metode traffic light system. Berdasarkan perhitungan dan analisis, disimpulkan bahwa untuk pencapaian kinerja rantai pasok PT SIP memiliki nilai sebesar 68.72 atau kondisi saat ini sudah cukup baik. Untuk mengoptimalkan kinerja rantai pasok, PT SIP perlu melakukan perbaikan pada metrik ketepatan waktu pengiriman Purchase Order (PO). Hasil brainstorming dengan operational manager menyimpulkan bahwa untuk peyebab tidak tercapainya metrik kinerja yang berwarna merah yaitu ketepatan perencanaan pengiriman.

Pendidikan adalah suatu usaha sadar dan terencana yang dilakukan untuk meningkatkan kualitas manusia yang diperoleh dari proses belajar mengajar. Universitas Pertamina adalah perguruan tinggi swasta yang membutuhkan infrastruktur dalam mendukung Kegiatan Belajar Mengajar (KBM). Gedung Griya Legita adalah salah satu infrastruktur yang digunakan Universitas Pertamina untuk proses KBM, perkumpulan organisasi, UKM, dan kegiatan lainnya. Permasalahan yang dihadapi dalam penggunaan gedung Griya Legita adalah terhambatnya kegiatan yang akan dilakukan akibat keterbatasan jumlah ruang kelas dan jadwal perkuliahan. Simulasi diskrit atau discrete event simulation (DES) dikembangkan untuk mencari alternatif solusi. Berdasarkan hasil pengembangan model simulasi, alternatif solusi optimal yang dihasilkan adalah dengan membangun 6 unit ruang kelas tambahan, sehingga variabel decline bernilai 0. Penambahan 6 unit ruang kelas mengakibatkan penurunan utilitas rata – rata ruang kelas menjadi 70,01%.
