Klinik Teluk Banten merupakan salah satu klinik yang berlokasi di Jalan Kampung Margagiri Kecamatan Puloampel Kabupaten Serang Provinsi Banten, beroperasi baru Sembilan bulan lamanya. Fasilitas yang tersedia salah satunya adalah poli pelayanan rawat jalan dan instalasi farmasi yang mengelola dan mengatur persedian obat. Tujuan dari penelitian ini adalah membuat prediksi terhadap pengelolaan persediaan obat. Pengelolaan persediaan obat pada klinik ini dilakukan setiap satu minggu sekali dengan pencatatan manual. Transaski penjualan obat pun dicatat dalam pembukuan biasa yaitu dicatat dalam buku besar, sehingga proses kontrol terhadap persedian obat belum dapat dilakukan dengan baik, tidak dapat dilakukan proses prediksi terhadap persediaan obat yang harus dibeli untuk periode berikutnya. Hal ini disebabkan karena catatan transaski penjualan yang tersedia hanya digunakan sebagai catatan dan arsip saja dan belum digunakan sebagai data yang dapat mendukung proses prediksi untuk menentukan obat yang harus disediakan untuk periode minggu selanjutnya. Permasalahan ini dapat diatasi dengan mengimplementasikan metode regresi linier sederhana yang dapat digunakan sebagai salah satu pendekatan untuk menghasilkan informasi berupa hasil prediksi untuk persediaan obat dalam proses penjualan obat jenis tablet. Berdasarkan perhitungan dengan menggunakan metode regresi linier diperolah akurasi sebesar 98, 505% yang artinya metode ini dapat diimplementasikan dalam membuat prediksi stok obat jenis tablet (ibu profen) pada Klinik Teluk.

Published: March 2022

ABSTRAKProduktivitas ternak potong yang rendah disebabkan oleh status nutrisi dan suplai hijauan sepanjang tahun yang rendah terutama pada musim kemarau. Indigofera zollingeriana merupakan salah satu tanaman pakan jenis leguminosa yang memiliki kandungan nutrien dan produksi yang tinggi, berumur panjang, dapat beradaptasi pada semua jenis tanah, dan toleran terhadap kekeringan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk kompos dan pupuk urea terhadap produksi tanaman I. zollingeriana. Penelitian disusun dalam rancangan acak lengkap pola faktorial. Faktor pertama adalah perlakukan pupuk kompos (K) dengan 3 taraf, yaitu K0 (tanpa pupuk kompos sebagai kontrol), K1 (5 ton/ha pupuk kompos) dan K2 (10 ton/ha pupuk kompos). Faktor kedua adalah pupuk urea dengan 4 taraf, masing-masing N0 (tanpa urea), N1 (150 kg/ha urea), N2 (300 kg/ha urea), N3 (450 kg/ha urea). Terdapat 48 satuan percobaan. Variabel yang diamati meliputi produksi hijauan segar, produksi bahan kering, rasio daun batang dan kandungan nutrien. Hasil penelitian menunjukkan bahwa kombinasi perlakuan pupuk kompos dan urea berpengaruh nyata terhadap produksi tanaman I. zollingeriana, yaitu terhadap produksi bahan kering. Produksi bahan kering tertinggi yaitu sebesar 38,57 g/polybag diperoleh pada kombinasi perlakuan 10 ton kompos/ha dengan 300 kg urea/ha (K2N2). ABSTRACTThe low productivity of beef cattle is due to the low nutritional status and supply of forage throughout the year, especially during the dry season. Indigofera zollingeriana is one of the leguminous forage plants that has high nutrient content and production, has a long life, can adapt to all types of soil, and is drought tolerant. The study aimed to determine the effect of compost and urea fertilizer on the production of I. zollingeriana. The research was arranged in a factorial completely randomized design. The first factor was the treatment of compost (K) with 3 levels, each K0 (without compost as control), K1 (5 tons/ha compost) and K2 (10 tons/ha compost). The second factor was urea fertilizer with 4 levels, which are N0 (without urea), N1 (150 kg/ha urea), N2 (300 kg/ha urea), N3 (450 kg/ha urea). There were 48 experimental units. The variables observed were fresh forage production, dry matter production, stem leaf ratio and nutrient content. Research result showed that the interaction between compost and urea had a significant effect on the production of I. zollingeriana plants, which was the dry matter The highest dry matter production 38.57 g/polybag reached by the interaction between 10 tons of compost/ha with 300 kg of urea/ha (K2N2).

Double dose of 5-aminolevulinic acid and its effect on protoporphyrin IX accumulation in low-grade glioma
Authors: Suero Molina Eric , Black David , Kaneko Sadahiro , Müther Michael , Stummer Walter 
Published: March 2022

OBJECTIVE
Administration of 5-aminolevulinic acid (5-ALA) does not regularly elicit fluorescence in low-grade glioma (LGG) at currently established doses and timing of administration. One explanation may be differences in blood-brain barrier (BBB) integrity compared to high-grade glioma. The authors hypothesized that for a BBB semipermeable to 5-ALA there might be a relationship between plasma 5-ALA concentration and its movement into the brain. A higher dose would elicit more 5-ALA conversion into protoporphyrin IX (PPIX). The authors present a case series of patients harboring LGG who received higher doses of 5-ALA.

METHODS
Patients undergoing surgery for indeterminate glioma later diagnosed as LGG were included in this study. 5-ALA was administered at a standard dose of 20 mg/kg body weight (bw) 4 hours prior to induction of anesthesia. A subgroup of patients received a higher dose of 40 mg/kg bw. Fluorescence was evaluated visually and PPIX concentration (cPPIX) was determined ex vivo by hyperspectral measurements in freshly extracted tissue. All adverse events were recorded.

RESULTS
A total of 23 patients harboring diffuse low-grade astrocytomas (n = 19) and oligodendrogliomas (n = 4) were analyzed. Thirteen patients received 20 mg/kg bw, and 10 patients received 40 mg/kg bw of 5-ALA. In the 20 mg/kg group, 30.8% (4 of 13) of tumors harbored areas of visible fluorescence, compared to 60% of cases (n = 6 of 10) with 40 mg/kg bw. The threshold to visibility was 1 μg/ml in both groups. Measured over all biopsies, the mean cPPIX was significantly higher in the double-dose group (1.8 vs 0.45 μg/ml; p < 0.001). In non–visibly fluorescent tissue the mean cPPIX was 0.146 μg/ml in the 20 mg/kg and 0.347 μg/ml in the 40 mg/kg group, indicating an increase of 138% (p < 0.001).

CONCLUSIONS
These observations demonstrate different regions with different levels of PPIX accumulation in LGG. With higher 5-ALA doses cPPIX increases, leading to more regions surpassing the visibility threshold of 1 μg/ml. These observations can be explained by the fact that the BBB in LGG is semipermeable to 5-ALA. Higher 5-ALA doses result in more PPIX conversion, an observation with implications for future dosing in LGG.
Spinal column shortening for tethered cord syndrome: a systematic review and individual patient data meta-analysis
Authors: McVeigh Luke G. , Anokwute Miracle C. , Chen Sixia , Jea Andrew 
Published: March 2022

OBJECTIVE
Tethered cord release (TCR) is the gold standard treatment for tethered cord syndrome (TCS); however, there are significant shortcomings including high rates of retethering, especially in complex and recurrent cases. Spinal column shortening (SCS) is an alternative treatment for TCS intended to avoid these shortcomings. Early studies were limited to case reports and smaller case series; however, in recent years, larger case series and small cohort studies have been conducted. Given the increase in available data, a repeat systematic review and meta-analysis is warranted to assess the safety and efficacy of SCS for TCS.

METHODS
The authors conducted a systematic review using MEDLINE (OVID), Embase (Elsevier), and Web of Science records dating from 1944 to July 2021 to identify all articles investigating SCS for TCS. They performed standard and individual patient data (IPD) meta-analyses, with 2 independent reviewers using PRISMA-IPD guidelines. Primary outcomes were improvement of preoperative clinical symptoms of pain, motor weakness, and bladder and bowel dysfunction, and also surgical complication rate. Secondary outcomes included urodynamic improvement and health-related quality-of-life outcomes determined using patient-reported outcome tools. Individual study quality assessment was performed using a standardized assessment tool for case reports/series, and publication bias was assessed using funnel plot analyses.

RESULTS
The review yielded 15 studies with 191 cases of TCS treated with SCS. IPD were available in 11 studies with 89 cases. The average age at time of surgery was 28.0 years (range 5–76 years). The average follow-up time was 33.2 months (range 7–132 months). Improvement was observed at last follow-up in 60 of 70 (85.7%) patients with preoperative pain, in 38 of 60 (60.3%) patients with preoperative weakness, and in 36 of 76 (47.4%) patients with preoperative bladder or bowel dysfunction. Complications of CSF leak, new neurological deficit, wound infection, or reoperation occurred in 4 of 89 (4.5%) patients.

CONCLUSIONS
SCS may be considered a safe and efficacious treatment option for TCS in children and adults (level C evidence; class IIb recommendation), especially for recurrent and complex cases. Current evidence is likely to be affected by selection and publication bias. Prospective comparative studies of SCS and TCR for TCS are recommended to determine long-term duration of outcomes, long-term safety in skeletally immature children, and exact indications of SCS versus traditional TCR.

Authors: Ohiorhenuan Ifije E. , Walker Corey T. , Zhou James J. , Godzik Jakub , Sagar Soumya , Farber S. Harrison , Uribe Juan S. 
Published: March 2022

OBJECTIVE
Lateral lumbar interbody fusion (LLIF) facilitates the restoration of disc height and the indirect decompression of neural elements. However, these benefits are lost when the graft subsides into the adjacent endplates. The factors leading to subsidence after LLIF are poorly understood. This article presents a case series of patients who underwent LLIF and reports factors correlating with subsidence.

METHODS
A retrospective review of a consecutive, prospectively collected, single-institution database of patients who underwent LLIF over a 29-month period was performed. The degree of subsidence was measured on the basis of postoperative imaging. The timing of postoperative subsidence was determined, and intraoperative fluoroscopic images were reviewed to determine whether subsidence occurred as a result of endplate violation. The association of subsidence with age, sex, cage size and type, bone density, and posterior instrumentation was investigated.

RESULTS
One hundred thirty-one patients underwent LLIF at a total of 204 levels. Subsidence was observed at 23 (11.3%) operated levels. True subsidence, attributable to postoperative cage settling, occurred for 12 (5.9%) of the levels; for the remaining 11 (5.4%) levels, subsidence was associated with intraoperative endplate violation noted on fluoroscopy during cage placement. All subsidence occurred within 12 weeks of surgery. Univariate analysis showed that the prevalence of true subsidence was significantly lower among patients with titanium implants (0 of 55; 0%) than among patients with polyetheretherketone cages (12 of 149; 8.1%) (p = 0.04). In addition, the mean ratio of graft area to inferior endplate area was significantly lower among the subsidence levels (0.34) than among the nonsubsidence levels (0.42) (p < 0.01). Finally, subsidence among levels with posterior fixation (4.4% [6/135]) was not significantly different than among those without posterior fixation (8.7% [6/69]) (p = 0.23). Multivariate analysis results showed that the ratio of cage to inferior endplate area was the only significant predictor of subsidence in this study (p < 0.01); increasing ratios were associated with a decreased likelihood of subsidence.

CONCLUSIONS
Overall, the prevalence of subsidence after LLIF was low in this clinical series. Titanium cages were associated with a lower prevalence of observed subsidence on univariate analysis; however, multivariate analysis demonstrated that this effect may be attributable to the increased surface area of these cages relative to the inferior endplate area.

OBJECTIVE
Data regarding risk factors for the progression of ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine are scarce. Therefore, in this study, the authors aimed to elucidate the difference in the radiographic progression pattern of OPLL and its risk factors between cervical and thoracic OPLL using longitudinally acquired whole-spine CT scans.

METHODS
Overall, 123 patients with symptomatic OPLL who underwent repeated whole-spine CT examinations, with an average interval of 49 months (at least 3 years) between scans, were retrospectively reviewed. Progression of OPLL was assessed to compare the distribution of OPLL over the entire spine on the initial and final CT scans. Patients were divided into a cervical OPLL (C-OPLL) group and a thoracic OPLL (T-OPLL) group according to the location of the main lesion. The progression pattern of OPLL and its risk factors were compared between the two groups using the Student t-test or Mann-Whitney U-test.

RESULTS
In the C-OPLL group, 15 (22.1%) of 68 patients had OPLL progression, of whom 12 patients (80.0%) had progression only in the cervical spine and 3 patients (20.0%) had progression in multiple regions (cervical and thoracic/lumbar). In the T-OPLL group, 16 (29.1%) of 55 patients had OPLL progression, of which 3 patients (18.8%) had progression only in the thoracic spine and 8 patients (50.0%) had progression in multiple regions. Young age was a common risk factor for OPLL progression regardless of the location of OPLL, and this trend was more pronounced in the T-OPLL group than in the C-OPLL group. High BMI, male sex, and multilevel, severe T-OPLL were identified as independent risk factors for progression of T-OPLL (OR 1.19, 95% CI 1.03–1.37; OR 10.5, 95% CI 1.39–81.94; and OR 1.24, 95% CI 1.16–1.45, respectively).

CONCLUSIONS
Patients with T-OPLL are predisposed to diffuse progression of OPLL over the entire spine, whereas patients with C-OPLL are likely to have progression in only the cervical spine. Young age and high BMI are significant risk factors for OPLL progression, especially in patients with T-OPLL. Our study highlights the need for continued follow-up in patients with T-OPLL, especially in young patients and those with obesity, for early detection of spinal cord and cauda equina symptoms due to the progression of OPLL throughout the spine.
Development of a methodology to assess the hydrocyclone process with account of the rheological properties of the mineral slurry
Authors: Aleksandrova Tatiana , Potemkin Vadim 
Published: March 2022

The paper studies the possibility of assessing the separation of mineral raw materials, taking into account the rheology of the mineral slurry. The ores of the Mayskoye deposit were chosen as the object of the study, characterized by a thin impregnation of the valuable component – gold in the host minerals, which determines the use of fine and ultrafine milling. This fact is essential because the presence of a fine grade seriously affects the rheology of the mineral slurry used in subsequent mineral processing stages. This predetermines the necessity to take into account rheological parameters. The research performed provides the development of a methodology for assessing the separation of minerals in the hydrocyclone based on the interpretation of numerical and mathematical modeling data. using the object-oriented programming language Python, a program for calculating empirical coefficients of the rheological equation, theoretically describing the dynamics of internal transformations of the mineral slurry, was developed. Taking into account the process parameters of the laboratory unit with hydrocyclone and ore properties, three concentrations of solids in the mineral slurry were selected, conditionally corresponding to the minimum, average and maximum values. Rheological equations successively composed for three concentrations, i.e., 400, 500, and 700 g/l, made it possible to calculate the critical shear rates corresponding to the maximum dispersion of the mineral slurry in the hydrocyclone flow. Subsequent numerical simulation using Ansys Fluent software, as well as statistical evaluation of the shear rates at different levels of solids content showed that the shear rate profile in the cross-section of the hydrocyclone corresponding to the maximum dispersion of the mineral slurry is obtained at the content of 400 g/l.

Authors: Cimino James J. 
Published: March 2022

The US National Library of Medicine’s Biomedical Informatics Short Course ran from 1992 to 2017, most of that time at the Marine Biological Laboratory in Woods Hole, Massachusetts. Its intention was to provide physicians, medical librarians and others engaged in health care with a basic understanding of the major topics in informatics so that they could return to their home institutions as “change agents”. Over the years, the course provided week-long, intense, morning-to-night experiences for some 1,350 students, consisting of lectures and hands-on project development, taught by many luminaries in the field, not the least of which was Donald A.B. Lindberg M.D., who spoke on topics ranging from bioinformatics to national policy.
The U.S. National Library of Medicine and standards for electronic health records: One thing led to another
Authors: McDonald Clement J. , Humphreys Betsy L. 
Published: March 2022

When Donald A.B. Lindberg M.D. became Director in 1984, the U.S. National Library of Medicine (NLM) was a leader in the development and use of information standards for published literature but had no involvement with standards for clinical data. When Dr. Lindberg retired in 2015, NLM was the Central Coordinating Body for Clinical Terminology Standards within the U.S. Department of Health and Human Services, a major funder of ongoing maintenance and free dissemination of clinical terminology standards required for use in U.S. electronic health records (EHRs), and the provider of many services and tools to support the use of terminology standards in health care, public health, and research. This chapter describes key factors in the transformation of NLM into a significant player in the establishment of U.S. terminology standards for electronic health records.
