Purpose: We present the paraspinal approach use for neuromuscular scoliosis with focus on deformity correction, perioperative (≤30 days) morbidity and outcome at a minimal follow-up length of 2 years. Methods: We prospectively collected data of 61 neuromuscular scoliosis patients operated using a paraspinal (Wiltse) approach between 2013 and 2019. We additionally collected data of 104 control cases, operated using a midline approach between 2005 and 2016. Fifteen Wiltse, respectively 37 control patients were excluded due to a short follow-up (<2 years), and 22 controls were excluded secondary to lacking follow-up data. Hence, 46 Wiltse and 45 control patients were compared. Results: Wiltse and control patients had comparable follow-up lengths, demographics, deformity corrections, complication rates, number of levels fused, and intensive care unit and hospital lengths of stay. Wiltse cases had a lower estimated blood loss (535 vs 1187 mL; p-value < 0.001), allogenic transfusion rate (48% vs 96%; p-value < 0.001), and operating time (ORT) (337 vs 428 min; p-value < 0.001) than controls. This was also the case when selecting for patients without pelvic fixation (p-values < 0.001). When selecting the cases with pelvic fixation (20 among 91 cases), only the number of levels fused and the ORT differed significantly according to the approach (p-value <0.015 and <0.041). Conclusion: The paraspinal approach for neuromuscular scoliosis is safe, associated with significant deformity correction, reduced estimated blood loss, and allogenic transfusion rate. These potential benefits still need to be evaluated, especially for cases with pelvic fixation, with further follow-up of larger cohorts. Level of evidence: level III.

Introduction: International guidelines recommend hospital care for patients with severe Coronavirus disease (COVID-19), but fragile health care systems struggle to cope with high number of admissions, placing patients at risk of receiving substandard care. We describe an outpatient ambulatory surveillance and treatment strategy (OPAT) for health care workers (HCWs) with severe COVID-19 during low hospital bed availability periods in Mexico City. Methods: In this observational, descriptive, retrospective study, we included HCWs with severe disease for whom there were no hospital beds available at the time of evaluation. We provided daily assessments by infectious disease specialists, daily ambulatory steroid, oral thromboprophylaxis and domiciliary low-dose oxygen. We recorded the number of patients who recovered, were hospitalized or died on follow-up. Results: From 18 March 2020 to 16 July 2021, 1739 HCWs attended our service. A total of 540 were diagnosed with COVID-19. Seventy-four had severe COVID-19 and needed hospitalization. Immediate hospitalization was not possible in 56 patients who were sent to the OPAT and included in our study. Twenty-four patients subsequently required hospitalization and 32 recovered as outpatients. Conclusions: We describe a feasible and safe outpatient management strategy for HCWs with severe COVID-19 in a low-resource setting.

The likelihood of contraceptive implant discontinuation is very common and varies worldwide. This high prevalence of discontinuation may also indicate problems with implementation of family planning programmes. Consequently, a significant number of women are exposed to conception after discontinuation. Although studies have been conducted in Ethiopia, there are inconsistencies across studies. Therefore, this meta-analysis aimed to estimate the pooled prevalence of contraceptive implant discontinuation among women in Ethiopia. Published articles from various electronic databases such as PubMed/MEDLINE, Google Scholar, Science Direct, AJOL and Cochrane library were systematically searched. All cross-sectional studies conducted on prevalence of contraceptive implant discontinuation and published up to 30 January 2022 were included in this review. To estimate the pooled prevalence, random effect model was used and a subgroup analysis was performed to identify the possible source of heterogeneity. Begg’s and Egger’s tests were used to identify possible publication bias. A total of 13 cross-sectional studies with 5012 participants were included. Significant heterogeneity was observed across studies (I2 = 98.2%). However, there was no evidence of publication bias (p = 0.066). The estimated pooled prevalence of contraceptive implant discontinuation in Ethiopia was found to be 36.95% (95% confidence interval = 27.6–46.3). A subgroup analysis by time of discontinuation indicated that 21.5%, 42.2% and 33.5% of contraceptive implant user discontinue within 12 months, 2.5 years and 3 years, respectively. This meta-analysis indicated that the prevalence of discontinuation of contraceptive implant was found to be high in Ethiopia. Therefore, strengthening the appropriate counselling prior to insertion and proper follow-up, independent choice will improve the proportion of implants retention.

Objectives: Routine dipstick urinalysis is a useful and inexpensive method for the early detection of asymptomatic diseases. Our study was carried out to detect the prevalence of urinary abnormalities among an apparently asymptomatic healthy female group and emphasize the value of routine dipstick urinalysis. Methods: A cross-sectional study was carried out among second to sixth (final)-year female medical students of Nnamdi Azikiwe University, Nnewi campus between 8 and 30 September 2019. A total of 100 subjects were enrolled. First-morning midstream urine samples were collected and promptly tested with dipstick strips. Subjects with abnormal findings were informed and treated appropriately. Results: In all, 54 (54%) of the subjects had urine abnormalities. Trace proteinuria was the commonest abnormality seen with a prevalence of 33%, followed by abnormal urine appearance (17%), leucocytes (14%), nitrites (8%) and urobilinogen (2%). Urine abnormalities were commoner in students who resided in the school hostel. Abnormal urine appearance was significantly associated with nitrites (0.003) and leucocytes (0.001). Conclusion: Routine dipstick urinalysis should be performed among students and apparently healthy individuals for early detection and diagnosis of renal diseases to facilitate quick interventions and prevent further progression.

Objective To identify the core components of digital behaviour change interventions for weight loss maintenance targeting physical activity, in terms of: (i) behaviour change techniques, (ii) mechanisms of action, (iii) modes of delivery, (iv) dose and (v) tailoring/personalization. In addition, the links between these components were investigated. Methods A literature search was performed in five electronic databases: PubMed, Embase, CINHAL, PsycINFO and Web of Science. Two reviewers independently screened the identified articles and extracted data related with the study characteristics and behaviour change techniques, mechanism of action, mode of delivery, dose, and tailoring, using standardized classifications whenever available (e.g. behaviour change techniques taxonomy). Results Seventeen articles reporting 11 original studies were selected. Two studies were protocols, 9 studies presented results for weight change and all but one showed no significant differences between the intervention and control groups. Eight studies (73%) provided adequate information on behaviour change techniques. Five studies (45%) provided partial information about how the behaviour change techniques were linked to mechanisms of action, and only one study (0.9%) described these links for all the techniques. Around half of the studies reported the modes through which behaviour change techniques were delivered. Descriptions of dose were present in most studies, but with minimal information. The use of tailoring or personalization approaches was mentioned in eight studies (73%), but descriptions of what was tailored and how were minimal. Conclusions The compilation of information regarding intervention components was difficult due to the lack of information and systematization in reporting across papers. This is particularly true for the reporting of the links between behaviour change techniques and the other core intervention components. This information is crucial to help us understand in the context of behaviour change interventions what works or does not work, how it works and why.

Abstract
Thromboses are major causes of morbidity and mortality in polycythemia vera (PV) and essential thrombocythemia (ET) diseases associated with JAK2V617F mutation. However, the molecular mechanism(s) of increased thrombosis in PV and ET remain unknown. Kruppel-like factor 2 (KLF2) is a transcription factor that regulates expression of genes associated with inflammation and thrombosis; the absence of KLF2 in neutrophils causes thrombosis by inducing tissue factor. We studied the role of KLF2 in regulating prothrombotic gene expression in PV and ET. Neutrophils and platelets KLF2 expression in PV and ET was lower than the controls. Furthermore, in patients with thromboses, KLF2 transcripts were lower in platelets than those without thromboses. JAK2V617F allelic burden was inversely correlated with KLF2 transcript levels, suggesting JAK-STAT pathway may downregulate KLF2 expression. Whole transcriptome analyses of neutrophils and platelets showed that a lower KLF2 expression was associated with an upregulation of KLF2-regulated thrombotic genes. In addition, low KLF2 expression in platelets positively correlated with thrombotic events. In patients with PV and ET, KLF2 expression was induced by pegylated interferon alfa (PegINF-α) but not by hydroxyurea treatments. These data suggest that KLF2 may be a regulator of PV and ET thrombosis and a novel therapeutic target to prevent thrombosis.
CMOS-Compatible Memristor for Optoelectronic Neuromorphic Computing

Published: November 2022

AbstractOptoelectronic memristor is a promising candidate for future light-controllable high-density storage and neuromorphic computing. In this work, light-tunable resistive switching (RS) characteristics are demonstrated in the CMOS process-compatible ITO/HfO2/TiO2/ITO optoelectronic memristor. The device shows an average of 79.24% transmittance under visible light. After electroforming, stable bipolar analog switching, data retention beyond 104 s, and endurance of 106 cycles are realized. An obvious current increase is observed under 405 nm wavelength light irradiation both in high and in low resistance states. The long-term potentiation of synaptic property can be achieved by both electrical and optical stimulation. Moreover, based on the optical potentiation and electrical depression of conductances, the simulated Hopfield neural network (HNN) is trained for learning the 10 × 10 pixels size image. The HNN can be successfully trained to recognize the input image with a training accuracy of 100% in 13 iterations. These results suggest that this optoelectronic memristor has a high potential for neuromorphic application.

Published: November 2022

Abstract
Background
Lumbar disc herniation is seen in 5–15% of patients with lumbar back pain and is the most common spine disorder demanding surgical correction. Spinal surgery is one of the most effective management for these patients. However, current surgical techniques still present complications such as chronic pain in 10–40% of all patients who underwent lumbar surgery, which has a significant impact on patients’ quality of life. Research studies have shown that transcutaneous electrical acupoint stimulation (TEAS) may reduce the cumulative dosage of intraoperative anesthetics as well as postoperative pain medications in these patients.

Objective
To investigate the effect of pTEAS on pain management and clinical outcome in major spinal surgery patients.

Methods
We conducted a prospective, randomized, double-blind study to verify the effect of pTEAS in improving pain management and clinical outcome after major spinal surgery. Patients (n = 90) who underwent posterior lumbar fusion surgery were randomized into two groups: pTEAS, (n = 45) and Control (n = 45). The pTEAS group received stimulation on acupoints Zusanli (ST.36), Sanyinjiao (SP.6), Taichong (LR.3), and Neiguan (PC.6). The Control group received the same electrode placement but with no electrical output. Postoperative pain scores, intraoperative outcome, perioperative hemodynamics, postoperative nausea and vomiting (PONV), and dizziness were recorded.

Results
Intraoperative outcomes of pTEAS group compared with Control: consumption of remifentanil was significantly lower (P < 0.05); heart rate was significantly lower at the end of the operation and after tracheal extubation (P < 0.05); and there was lesser blood loss (P < 0.05). Postoperative outcomes: lower pain visual analogue scale (VAS) score during the first two days after surgery (P < 0.05); and a significantly lower rate of PONV (on postoperative Day-5) and dizziness (on postoperative Day-1 and Day-5) (P < 0.05).

Conclusion
pTEAS could manage pain effectively and improve clinical outcomes. It could be used as a complementary technique for short-term pain management, especially in patients undergoing major surgeries.

Combination of thoracic epidural analgesia with patient-controlled intravenous analgesia versus traditional thoracic epidural analgesia for postoperative analgesia and early recovery of laparotomy: a prospective single-centre, randomized controlled trial
Authors: Xu Wenwen , Li Youpei , Li Nanqi , Sun Yu , Wang Chao , An Ke 
Published: November 2022

Abstract
Background
Thoracic epidural analgesia (TEA) has always been the first choice for postoperative pain treatment, but associated complications and contraindications may limit its use. Our study put forward a new analgesic strategy that combines TEA with patient controlled intravenous analgesia (PCIA) to optimize TEA.

Methods
Patients undergoing laparotomy were enrolled in this prospective randomized study. Patients were randomized to one of two groups: TEA/PCIA group and TEA group. Patients in TEA/PCIA group received TEA in the day of surgery and the first postoperative day and PCIA continued to use until the third postoperative day. Patients in TEA group received TEA for three days postoperatively. Visual analogue scale (VSA) pain scores at rest and on movement at 6, 24,48,72 h after surgery were recorded. In addition, the incidence of inadequate analgesia, adverse events, time to first mobilization, time to pass first flatus, time of oral intake recovery, time of urinary catheter removal, postoperative length of hospital stay, cumulative opioid consumption, and the overall cost were compared between the two groups. We examined VAS pain scores using repeated measures analysis of variance; P < 0.05 was considered as statistically significant.

Results
Eighty-six patients were analysed (TEA/PCIA = 44, TEA = 42). The mean VAS pain scores at rest and on movement in TEA/PCIA group were lower than TEA group, with a significant difference on movement and 48 h postoperatively (P < 0.05). The time to first mobilization and pass first flatus were shorter in TEA/PCIA group (P < 0.05). Other measurement showed no statistically significant differences.

Conclusions
The combination of TEA with PCIA for patients undergoing laparotomy, can enhance postoperative pain control and facilitate early recovery without increasing the incidence of adverse effects and overall cost of hospitalization.

Abstract
Background
Influenza is responsible for more than 5 million severe cases and 290,000 to 650,000 deaths every year worldwide. Developing countries account for 99% of influenza deaths in children under 5 years of age. This paper aimed to determine the dynamics of influenza viruses in African transmission areas to identify regional seasonality for appropriate decision-making and the development of regional preparedness and response strategies.

Methods
We used data from the WHO FluMart website collected by National Influenza Centers for seven transmission periods (2013–2019). We calculated weekly proportions of positive influenza cases and determined transmission trends in African countries to determine the seasonality.

Results
From 2013 to 2019, influenza A(H1N1)pdm2009, A(H3N2), and A(H5N1) viruses, as well as influenza B Victoria and Yamagata lineages, circulated in African regions. Influenza A(H1N1)pdm2009 and A(H3N2) highly circulated in northern and southern Africa regions. Influenza activity followed annual and regional variations. In the tropical zone, from eastern to western via the middle regions, influenza activities were marked by the predominance of influenza A subtypes despite the circulation of B lineages. One season was identified for both the southern and northern regions of Africa. In the eastern zone, four influenza seasons were differentiated, and three were differentiated in the western zone.

Conclusion
Circulation dynamics determined five intense influenza activity zones in Africa. In the tropics, influenza virus circulation waves move from the east to the west, while alternative seasons have been identified in northern and southern temperate zones. Health authorities from countries with the same transmission zone, even in the absence of local data based on an established surveillance system, should implement concerted preparedness and control activities, such as vaccination.

Abstract
Objective
To retrospectively analyze CT and MR imaging features of the brain in patients with hydrogen sulfide poisoning based on clinical symptom grading and to investigate their correlations with clinical symptoms and patients’ prognosis.

Methods
A retrospective analysis was performed of CT and MR imaging data of the brain in 40 patients with hydrogen sulfide poisoning in our hospital. There were four main imaging manifestations. Patients were clinically graded according to the central nervous system symptom scores of the Poisoning Severity Score (PSS) and staged according to the gas inhalation time segment. Based on clinical symptom grading, the frequencies and proportions of four imaging signs that occurred in each group were counted, their development trends were analyzed, and the correlations of imaging features with clinical grading and prognosis were calculated.

Results
Forty patients were divided into minor, moderate and severe clinical grades and classified into four stages. In patients with minor and moderate clinical grading, only one patient suffered from generalized brain edema at stage 1, with a good prognosis. Patients with severe clinical grade showed the highest probability of presenting with the four imaging signs. The imaging signs were correlated with the severe clinical grade and a poor prognosis (P = 0.000, R = 0.828; P = 0.000, R = 0.858).

Conclusion
In patients with the severe clinical grade, generalized brain edema and symmetrical hypodensity/abnormal signals in the bilateral basal ganglia and around the lateral ventricles were the main findings and were shown to persist. The presence of imaging signs can assist in the clinically effective evaluation of clinical symptom grade.
