Impact of the COVID-19 pandemic on inpatient antibiotic use in Indonesia and the Philippines

Background: The coronavirus disease 2019 (COVID-19) pandemic severely affected Southeast Asia, with >35 million cases and ~360,000 deaths. Despite relatively low rates of secondary bacterial infection among inpatients with COVID-19, several countries reported increased antibiotic use; raising concerns for worsening antimicrobial resistance. We assessed the impact of the COVID-19 pandemic on the use of antibiotics commonly used to treat respiratory infections in Southeast Asia. Methods: We evaluated intravenous antibiotic use among hospitalized adults in acute-care wards in 6 hospitals; 3 in Indonesia and 3 in the Philippines. We abstracted data on antibiotics that are commonly used to treat respiratory infections in these hospitals. We calculated antibiotic use rates for the 25 included antibiotics as monthly defined daily dose per 1,000 patient days (or patient discharges where patient days was unavailable) using data from pharmacy dispensing records and administrative records. Median antibiotic use rates for the prepandemic period (March 2018–February 2020) and the pandemic period (March 2020–February 2021) were compared, and percentage changes were calculated for (1) all 25 antibiotics combined; (2) ceftriaxone; (3) vancomycin and linezolid combined (anti-MRSA); and (4) broad-spectrum antibiotics with activity against Pseudomonas aeruginosa (anti-PSA). Monthly antibiotic use and COVID-19 patient discharges were graphed over the 36-month study period (March 2018–February 2021) to visualize trends (Fig. 1). The Wilcoxon rank-sum test was used to determine whether differences in median antibiotic use rates were statistically significant (2-tailed P < .05). Results: Overall, trends in antibiotic use were higher during months with increased COVID-19 patient discharges (Fig. 1). Use of all 25 antibiotics combined significantly increased in 4 of 6 hospitals (6.9%–63.6%) during the pandemic period compared to the prepandemic period. Ceftriaxone use significantly increased in 3 of 6 hospitals (37.1%–55.4%) and decreased in 3 of 6 hospitals (15.9%–31.9%). Anti-PSA antibiotic use significantly increased in 4 of 6 hospitals (16.1%–161.5%). Although anti-MRSA antibiotic use was low (comprising <2% of the overall included antibiotic use in Indonesia and <11% in the Philippines), use during the pandemic increased in 3 of 6 hospitals (59.8%–212.6%). Conclusions: We observed substantial increases in antibiotic use among hospitalized adults in Indonesia and the Philippines during the COVID-19 pandemic. The increased use of broad-spectrum antibiotics is concerning given the potential consequence of worsening antimicrobial resistance. Understanding how increases in antibiotic use compares to rates of bacterial infection, antimicrobial resistance, and antibiotic availability and accessibility during this time is important to contextualize results. These findings reinforce the importance of antibiotic stewardship practices to optimize antibiotic use, especially during pandemics

Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity &gt; 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P &lt; 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Desain Proyek Pabrik Isopropilamin dari Proses Aminasi Isopropanol dengan Katalis Ni/LaAlSiO dengan Kapasitas 11.000 Ton/Tahun

Isopropilamin atau yang dikenal juga sebagai monoisopropilamin (MIPA) adalah senyawa kimia organik yang termasuk dalam kelompok amina. Senyawa dengan rumus molekul (CH3)2CHNH2 tersebut secara struktural merupakan amina primer, karena sebuah gugus alkil dan dua buah atom hidrogen terikat pada atom nitrogen. Isopropilamin umumnya berbentuk cairan tak berwarna dengan bau seperti amonia. Pengaplikasian isopropilamin dikembangkan dalam penggunaan farmasi seperti bahan untuk mensintesis obat dan digunakan dalam proses kimia dalam industri. Hingga saat ini, isopropilamin telah digunakan secara luas dalam berbagai industri seperti pada industri kimia, farmasi, pertanian, dan lainnya. Berdasarkan data BPS tahun 2022, Indonesia mengimpor isopropilamina sebanyak 7.951 ton. Dengan berdirinya pabrik isopropilamin dengan kapasitas 11.000 ton/tahun, diharapkan kuantitas impor isopropilamin ke Indonesia dapat berkurang dan Indonesia sendiri juga dapat mengekspor isopropilamin ke luar negeri. Proses pembuatan isopropilamin dapat dibuat dengan berbagai jenis reaksi dan berbagai jenis bahan baku seperti proses hidorgenasi amonia dan aseton maupun dengan proses aminasi amonia, isopropanol dan hidrogen. Namun proses hidrogenasi memiliki kelemahan dimana adanya limbah berupa amonia yang berbahaya dibandingkan dengan isopropanol sedangkan proses aminasi cenderung memiliki konversi yang rendah. Untuk mengatasi kelemahan tersebut, maka digunakan proses aminasi dengan katalis Ni/AlSiO3 dimana limbahnya lebih ramah lingkungan dibandingkan aseton dan masih memiliki konversi reaksi yang tinggi. Adapun produk samping dari reaksi ini berupa diisopropilamin dan air. Produksi isopropilamin dengan proses yang dipilih menggunakan isopropanol, amonia, dan hidrogen sebagai umpan fixed bed reactor yang sudah berisi katalis Ni/AlSiO3. Isopropanol direncanakan diperoleh dari ExxonMobil Chemical Co. yang berlokasi di Los Angeles, amonia direncanakan diperoleh dari PT Pupuk Kalimantan Timur, dan hidrogen direncanakan diperoleh dari PT. Air Products Indonesia

Analisis Face Image Rotate Detection Sebagai Authentication Face Biometric

Penggunaan wajah merupakan bagian unik pada manusia yang mudah untuk diperoleh, dalam tekniknya otentikasi, saat ini biometrik pengenalan wajah digunakan sebagai metode yang banyak digunakan sebagai otentikasi keaslian dari pengguna. Hal ini dikarenakan penggunaan wajah sebagai identitas unik individu yang hanya dimiliki oleh seseorang dan sukar untuk dipalsukan. Namun rotasi wajah adalah komponen variabel dan membuat deteksi wajah menjadi tugas yang kompleks dan menantang dengan berbagai sudut dan rotasi (Verma, et al., 2022), jika kepala berubah posisi bergerak kebawah (depresi) dan bergerak keatas (elevasi) akan mempengaruhi keterbacaan wajah. Tujuan dari penelitian ini adalah Analisis perubahan posisi kepala depresi dan elevasi dapat mempengaruhi keterbacaan face image dalam otentikasi biometrik wajah. Hasil dari analisis data dapat disimpulkan bahwa dalam penggunaan wajah sebagai authentication biometric perputaran wajah elevasi mapun depresi tidak disarankan lebih dari 270. Hal ini mengakibatkan wajah tidak dikenali karena struktur anggota wajah, seperti mata, mulut dan hidung tidak telihat dengan jelas, sedangkan face distance euclidean kemiripan wajah perputaran elevasi dan depresi wajah dianggap mirip pada perputara 00 sampai perputaran 270. Sedangkan derajat diatas 270 kemiripan wajah tidak stabil dan cenderung tidak miri
