Background: The prevalence of sleep problems is approximately 40% among the general and health-care populations. Post-covid-19 sleep disturbances may persist for a long time and are often precursors of psychiatric disorders and expeditors of many systemic diseases. Studies on sleep quality in COVID-19 patients are considerable but in post-COVID-recovered subjects are scanty. There is no study on sleep quality of such patients in Eastern India.
Aims and Objectives: We hypothesize that both sleep disturbances and sleep quality may be affected in subjects in their post-COVID state. Therefore, we planned to study the prevalence of sleep disturbances, sleep quality, severity of insomnia, and the relationship of different parameters with respect to sleep quality.
Materials and Methods: Two hundred and fifty COVID-19-recovered patients were administered a pre-structured questionnaire including Pittsburgh sleep quality index and insomnia severity index containing various sleep parameters.
Results: Majority of the study participants had sleep disturbances in the form of change in sleep pattern (59.6%), poor sleep quality (77.6%), reduced sleep duration (29.6%), daytime sleepiness (20%), difficulty in sleep initiation (29.6%), and subthreshold insomnia (53.6%). Poor sleep quality was strongly associated with reinfection, change in sleep pattern after infection, sleep pattern alteration during pandemic, and those who felt tired during daytime.
Conclusion: This study concludes that a significant number of COVID-19-recovered subjects experienced sleep disturbances including poor sleep quality.

Published: November 2023

Background: Tumor proliferation is a key prognostic factor in breast cancer, but the relationship between tumor proliferation and prognosis remains unclear.
Aims and Objectives: To investigate the association between tumor proliferation and prognosis in breast cancer patients using a pathological analysis.
Materials and Methods: A retrospective cohort study was conducted, including 100 breast cancer patients who underwent surgical resection between January 2021 and December 2022.Tumor proliferation was assessed using Ki-67 immunostaining and evaluated patient prognosis based on disease-free survival (DFS) and overall survival (OS). We performed statistical analyses to examine the association between tumor proliferation and prognosis.
Results: Our results showed a significant correlation between tumor proliferation and prognosis in breast cancer patients. High Ki-67 expression was associated with shorter DFS and OS, while low Ki-67 expression was associated with longer DFS and OS. The difference in DFS and OS between high and low Ki-67 expression groups was statistically significant.
Conclusion: Tumor proliferation is a valuable prognostic marker in breast cancer and could be used to guide treatment decisions. Our findings suggest that patients with high Ki-67 expression may benefit from more aggressive treatment options, while patients with low Ki-67 expression may be able to avoid unnecessary treatment and its associated side effects. The accurate assessment of tumor proliferation using Ki-67 immunostaining could potentially improve patient outcomes and reduce the burden of breast cancer treatment.
A comparative study of intraoperative analgesic consumption and recovery profile between sevoflurane- and propofol-based general anesthesia in adults
Authors: Ray Abanish , Das Debojyoti , Shaw Sweta , Chakraborty Soma , Laha Arpita , Mandal Mohanchandra
Published: November 2023

Background: Many researches were performed in the past to compare propofol and sevoflurane as sole anesthetics. While some studies have reported the advantages of propofol regarding better recovery profile and post-operative analgesic sparing effect, the contrast reporting does exist. Hence, there is a further need of research to explore recovery characteristics. Whether either of these two as sole anesthetics can yield any benefit regarding intraoperative analgesics consumption has not been evaluated.
Aims and Objectives: The study primarily aimed at determining total analgesic consumption in the intraoperative period (primary outcome), between those receiving either sevoflurane or propofol for induction as well as maintenance of anesthesia. In addition, intraoperative hemodynamics (heart rate and mean arterial pressure) and recovery profile were compared.
Materials and Methods: Total of 168 patients, aged 18–60 years, the American Society of Anesthesiologists’ physical status I/II, undergoing elective and emergency surgeries under general anesthesia for 2–3 h finally recruited. Patients were randomly allocated to receive either sevoflurane (group S, n=84) or propofol (group P, n=84) for both induction and maintenance. Anesthetics were titrated to achieve bispectral index (BIS) value of 60. For both the groups, additional fentanyl was considered aliquots of 25 mcg whenever the hemodynamics changes occurred despite maintaining BIS value in the above-mentioned range.
Results: The total intraoperative analgesic consumption was found comparable in both groups of patients. Induction time (38 vs. 59 s) and emergence time (8 vs. 10 s, P<0.001) were found shorter in the propofol group than in sevoflurane. Aldrete score >9 was achieved earlier with propofol compared with sevoflurane (8.5 vs. 12 min).
Conclusion: Propofol-based shows no advantage over sevoflurane in view of intraoperative consumption of analgesics and intraoperative hemodynamic stability. However, the use of propofol was associated with faster induction as well as quicker emergence from anesthesia.
Anesthetic considerations in supravalvular aortic stenosis: A case series
Authors: Virendra Kumar  , Mona Swain  , Ira Balakrishnan M  , Vineesha G
Published: November 2023

Supravalvular aortic stenosis (SVAS), characterized by elastin arteriopathy, presents either as a localized narrowing at the sinotubular junction or as a diffuse form with additional involvement of the ascending aorta, aortic arch, and its branches. Associated lesions of the aortic valve, coronary artery narrowing, and pulmonary artery stenosis can further complicate the disease process. These patients are inherently at risk for developing myocardial ischemia, particularly in the setting of anesthesia or sedation. The left ventricular hypertrophy, secondary to the obstruction, results in increased left ventricular wall tension and myocardial oxygen consumption. Associated anatomic factors in the coronary arteries can further impair coronary blood flow. Any anesthetic drug that further increases oxygen consumption or decreases the coronary blood flow will result in an imbalance and increase the risk of cardiac arrest. We present a series of three patients with SVAS who were operated at our institute and subsequently discharged with good outcomes. The hemodynamic goal during the perioperative should aim to balance the myocardial oxygen supply-demand ratio. Extreme vigilance and aggressive resuscitative measures are needed to prevent any adverse myocardial event that can happen immediately after anesthetic induction or during periods of intense sympathetic stimulation such as laryngoscopy, sternotomy, aortic cannulation, or during emergence from anesthesia.

Authors: Kishor Kumar B  , Ramani C P  , Sudha N
Published: November 2023

Background: Implant site and periprosthetic joint infections (PPJI) are of major concern with tremendous improvement in orthopedic operative procedures. Early diagnosis of infection is the cornerstone for success rate and prevention of implant failure. The need for inflammatory biomarkers followed by culture sensitivity remains inevitable in the diagnosis of infection.
Aims and Objectives: The aim is to study the prevalent biofilm-forming pathogens and to correlate with antimicrobial resistance and also to estimate inflammatory markers to predict the presence of PPJI.
Materials and Methods: A descriptive cross-sectional study involving 57 patients showing signs of PPJI was evaluated. Clinical samples of these cases were processed, the bacterial pathogens were isolated and bio-film formation was tested. Inflammatory markers C-reactive protein by latex agglutination and interleukin-6 (IL6) by ELISA is determined.
Results: A total of 36 bacterial pathogens are isolated, 17% are Gram-positive cocci (GPC) and 46% are Gram-negative bacilli (GNB). Among these, 54% are biofilm producers and pseudomonas species (33%) are predominant. Antibiotic susceptibility studies showed GPC to be highly sensitive to linezolid (100%) and vancomycin (100%). Among GNB, pseudomonal species showed susceptibility of 85%, 57%, and 47% to meropenem, amikacin, and piperacillin–tazobactam, respectively. Acinetobacter is the most resistant isolate. The IL value of 19.5 arrived by the receiver operating curve showed maximum sensitivity and minimal false positivity.
Conclusion: Assessing the infection-specific biomarkers like IL6 levels is advantageous in earlier detection of implant site infection and aid in instituting specific antibiotics for the most common implant and PPJI before permanent implant failure and sepsis.

Published: November 2023

Background: Chronic obstructive pulmonary disorder (COPD) is a prevalent and debilitating respiratory condition characterized by chronic inflammation within the airways and lung tissues. By elucidating the specific mediators involved and their potential therapeutic implications, this research seeks to contribute to a better understanding of the inflammatory mechanisms underlying COPD and explore novel avenues for managing the disease.
Aims and Objectives: The objective of study is to determine systemic anti-inflammatory mediators in COPD and its correlation with disease severity.
Materials and Methods: The study analyzed systemic levels of several anti-inflammatory mediators, namely, soluble interleukin 1 receptor II (sIL-1RII), soluble tumor necrosis factor receptor p55 (sTNF-R55), and sTNF-R75, as well as C-reactive protein (CRP) and lipopolysaccharide binding protein (LBP), in 55 patients with stable COPD (median forced expiratory volume in 1 s [FEV1] of 34% predicted, ranging from 15% to 78%) and compared them with 23 control subjects. In addition, changes in these mediators were studied in 13 COPD patients (median FEV1 of 34% predicted, ranging from 19% to 51%) during the first 7 days of hospitalization for an exacerbation of the disease.
Results: The results revealed that patients with stable COPD showed evidence of a systemic inflammatory process, characterized by an elevated leukocyte count, increased levels of CRP and LBP, and moderate increases in both sTNF-Rs. However, the sIL-1RII levels did not differ significantly between patients and controls. During the treatment of disease exacerbations, systemic levels of CRP (at day 3) and LBP (at day 7) significantly decreased compared to day 1, while sIL-1RII levels increased.
Conclusion: Based on these findings, it is suggested that there is an imbalance in systemic levels of pro- and anti-inflammatory mediators in patients with stable COPD. The observed increase in the anti-inflammatory mediator sIL-1RII during treatment of exacerbations may play a role in the clinical improvement observed in these patients.

Published: November 2023

With the rapid growth of high-rise buildings and large-scale structures, there is a need to preserve natural resources and reduce loads on buildings by using lightweight concrete to achieve better performance for structures. In the study, four groups were prepared; the first group included one mix containing natural aggregate, and the second mix replaced all the natural aggregates with lightweight pumice aggregates. These mixes are reinforced with carbon fiber with a 0.5% volume fraction. In the second group, a variable volume fraction of carbon fiber of (0.0 and 1%) of mixes. In the third group, the mixes have different lengths of carbon fiber (20mm, 30mm) and a volume fraction of carbon fibers 0.5%. Finally, the fourth group partially replaces sand as a variable with a percentage of lightweight fine aggregates (10% and 30%) reinforced with fibers. Adding carbon fibers to the concrete specimens by 0.5% and 1% improved splitting tensile strength and flexural strength compared to the specimens containing carbon fibers with a length of 5mm. Also, enhanced samples containing fibers by 0.5% and lengths of 20 mm or 30 mm, compared to the sample containing carbon fibers with a length of 5 mm. Also, the specimens containing lightweight fine aggregates as a replacement with a percentage of sand have a lower splitting tensile strength and flexural strength than the reference mix.

First-principles study on transition-metal doping and band-structure modulation in ZnO
Authors: Kang Youngho
Published: November 2023

Transparent conducting oxides (TCOs) have both the electrical conductivity of a metal and the optical transparency of an insulator. Due to this unique feature, TCO is utilized in various applications such as flat panel displays, solar cells, light emitting diodes, and smart windows. At present, Sn-doped In2O3 (ITO) is the most widely used in the TCO market because of the superior materials properties. However, due to the demand for higher conductivity, instability of indium supply and high price, research to find new TCO materials has been continuously conducted. In this study, to develop a new TCO based on ZnO, we investigate the thermal stability of the transition metal dopants Sc and V and their effect on the band structure of ZnO using first-principles calculations. Our results show that Sc and V are efficient donors that can generate one free electron by substituting Zn when doped into ZnO. Furthermore, by analyzing the band structure of the doped system and calculating the electron effective mass, we show that Sc and V doping can be an important strategy to develop ZnO-based high-performance TCOs.
Assessing the state of LGBTQ+ diversity and inclusion in neurosurgery
Authors: Foresi Brian D. , Pellot Karolina , Quadri Saif S. , Muzyka Logan , White Sarah , Uzoukwu Cynthia , Pannullo Susan C.
Published: November 2023

OBJECTIVE

The aim of this study was to assess the diversity of neurosurgeons in terms of lesbian, gay, bisexual, transgender, and/or queer (LGBTQ+) gender and sexual minority status using the Graduation Questionnaire (GQ) as the single nationalized source of LGBTQ+ identification. Additionally, inclusivity was assessed through interviews by residents and attendings in the field.

METHODS

First, a PRISMA literature review was conducted and independently reviewed by two authors on studies involving LGBTQ+ representation in neurosurgery from PubMed, Web of Science, and Google Scholar. Then, aggregate responses of 16,901 participants’ sexual and gender identities from the GQ administered between 2016 and 2022 were compiled. To statistically analyze the response frequencies, the authors performed a chi-square analysis. Finally, interviews were conducted with individuals who identify as LGBTQ+ and are currently neurosurgical residents or attendings. Direct invitations were extended to participate in interviews, and all participants gave informed consent prior to the interview. Interviews were conducted using standardized questions and were video recorded.

RESULTS

Two studies were identified by literature review that referenced the LGBTQ+ community in neurosurgery. A GQ chi-square analysis comparing neurosurgical with nonneurosurgical LGBTQ+ identification proved statistically insignificant (p = 0.65). More broad analysis of majority sexual and gender identification (heterosexual and cisgendered) compared with the total gender and sexual minority group also proved statistically insignificant (p = 0.32) in response frequency. Five interviews, including 4 residents and 1 attending, provided several overarching themes including self-identification as an invisible minority, self-limiting behavior to ensure inclusion, and LGBTQ+ status as a direct departure from the stereotypical neurosurgeon.

CONCLUSIONS

Results from the GQ analysis indicate that neurosurgery is achieving LGBTQ+ diversity of its incoming members comparable to that of other fields in medicine. However, qualitative data from the interviews and a lack of specific literature indicate that despite obtaining diversity, inclusion of LGBTQ+ neurosurgeons and trainees is lacking.

OBJECTIVE

Studies have demonstrated the benefits of diversity in neurosurgery. However, recruitment of minoritized groups within the neurosurgical workforce consistently lags other surgical specialties. While racial and gender demographics of neurosurgical residents are well documented, there has been minimal exploration into the multidimensional nature of diversity. The current study will evaluate the longitudinal diversity changes in neurosurgery residency programs compared with other surgical fields with validated diversity indices.

METHODS

Nationwide reports including data about resident physicians were obtained from the American Medical Association and the Association of American Medical Colleges for the academic years 2008–2021. Self-reported race, biological sex, and medical school affiliation were recorded for surgical residents in the 10 commonly recognized surgical fields. The Gini-Simpson Diversity Index was used to calculate the effective counts (ECs) of races, sexes, and medical school types for each field. A Composite Diversity Index (CDI) comprising the aforementioned diversity traits was used to calculate the percentage of characteristics upon which two randomly selected residents within each specialty would differ. CDIs were calculated for each field in every year from 2008 to 2021. Median CDIs were compared between fields using Kruskal-Wallis testing, and p values < 0.05 were deemed statistically significant.

RESULTS

Plastic surgery had the highest median sex EC (1.92, interquartile range [IQR] 1.78–1.95), indicating greater diversity, while neurosurgery had the third lowest sex EC (1.40, IQR 1.35–1.41). All surgical fields examined had fewer than 3 races effectively represented among their residents, despite there being 8 races present. Neurosurgery ranked among the top fields in effective racial diversity (EC 2.17, IQR 2.09–2.21) and medical school type diversity (EC 1.25, IQR 1.21–1.26). There were statistically significant differences in the sex, race, and school ECs between surgical specialties. While neurosurgery had a relatively low median overall diversity (CDI = 32.7, IQR 32.0–34.6), there was a consistent longitudinal increase in CDI from 2015 to 2021.

CONCLUSIONS

Neurosurgery resident physicians have become increasingly diverse in the past decade but are more homogenous than residents in other surgical fields. The continued use of diversity indices to more accurately track diversity progress over time may better inform leaders in the field of how they may best focus their equity and inclusion efforts.

Authors: Kusdiyono Kusdiyono , Mulyono Tedjo , Supriyadi Supriyadi
Published: November 2023

Fly ash dan bottom ash merupakan limbah padat dihasilkan sisa pembakaran batubara pada pembangkit listrik tenaga uap atau proses industri lainnya. Limbah padat ini terdapat dalam jumlah yang relatif besar, sehingga memerlukan pengelolaan yang serius agar tidak menimbulkan masalah pencemaran lingkungan, seperti pencemaran udara, perairan dan penurunan kualitas ekosistem lainnya. Fenomena yang terjadi, penanganan limbah ini tidak maksimal, terbukti masih adanya perusahaan membuang abu batu bara di Jalan lingkar selatan kota Salatiga (Suara Merdeka, 2012), limbah batu bara makan korban di Kayen, Pati (Sura Merdeka, 2012), kejadian seperti ini menunjukkan bahwa pengelolaan limbah padat dari industri tidak dikelola dengan baik. Sementara penelitian dibidang Rekayasa Bahan sudah banyak dilakukan oleh peneliti sebagai upaya untuk memecahkan permasalahan dan memanfaatkan limbah industri ini untuk dapat diproduksi menjadi industri lain seperti bahan bangunan. Hasil penelitian menunjukkan bahwa mutu paving (Bata beton) dengan bentuk empat persegi panjang dengan ukuran 60 mm x 100 mm x 200 mm dan model/jenis B2,5, B5, B7,5, B10, B12,5, B15, B17,5 dan B20 terdapat peningkatan kuat tekan rata-rata dibanding dengan model/jenis BN (tanpa penambahan fly ash dan bottom ash). Tertinggi pada penambahan fly ash dan bottom ash 5% dengan kekuatan tekan rata-rata mencapai 225,37 kg/cm² umur 14 hari, sedang penurunan terjadi pada penambahan fly ash dan bottom ash mulai dari 7,5% sampai 20% dengan penurunan kuat tekan rata-rata terendah 144,36 kg/cm² pada umur uji 14 hari. Persamaan regresi yang didapat Y= - 4,130 X² - 38,91 X + 117,2 dengan nilai korelasi R² = 0,766, artinya dengan penambahan fly ash dan bottom ash mempunyai pengaruh kuat terhadap kuat tekan paving (Bata beton). Sehingga diperoleh suatu gambaran bahwa dengan menambahkan fly ash dan bottom ash pada pembuatan paving (Bata beton) mutunya dapat menjadi lebih baik.

Pengolahan limbah padi (jerami) kering masih sangat minim, mayoritas petani akan membakar jerami padi kering supaya lahan dapat ditanami kembali. Padahal jika dikelola dengan baik, jerami padi kering dapat dibuat tepung yang digunakan sebagai campuran pakan bagi hewan ternak unggas. Untuk mengubah sampah jerami padi kering menjadi campuran pakan hewan unggas diperlukan alat teknologi tepat guna yang efektif dan praktis, sehingga mudah diopersikan dan menghasilkan bentuk produk pengolahan jerami yang sesuai kebutuhan. Beberapa studi dan pembuatan alat sudah dilakukan dengan menggunakan berbagai mekanisme. Pada penelitian kali ini akan dibuat mesin penghancur jerami padi dengan mengoptimalkan bentuk dan dimensi pisau potong sehingga dapat menghasilkan ukuran potongan yang sesuai dan mempunyai kapasitas dan kecepatan potong yan besar. Proses rancang bangun pisau pemotong jerami pada mesin penghancur jerami padi ini menggunakan metode perancangan VDI 2222 untuk mempermudah dalam proses perancangan, yaitu dengan melakukan tahapan merencana, mengkonsep, merancang, penyelesaian. Dari hasil perancangan didapatkan bahwa pisau penghancur pada mesin penghancur jerami padi memiliki beberapa komponen yaitu bilah pisau, piringan atas, ring kipas, kipas pendorong, pilar penopang, dan piringan bawah. Pisau potong berbentuk serrated edge atau mata pisau yang bergerigi. Hasil perencanaan pisau penghancur pada mesin penghancur jermi padi, ditetapkan jumlah pisau sebanyak 8 (delapan) buah. Dengan jumlah pisau tersebut kecepatan hasil potong yang dihasilkan adalah 0,018 m3/menit serta kapasitas pemotonganya sebanyak 25,9 kg/menit. Ukuran hasil potongan menunjukkan bahwa penggunaan pisau bergerigi menghasilkan ukuran potong antara 7-10 mm, sedangkan bentuk pisau rata menghasilkan potongan 10 – 15 mm.
