Published: February 2022

ObjectiveTo assess the feasibility of implementing a web-based discharge education programme for general surgery patients both prior to and after hospital discharge.Design, setting and participantsThis is a prospective, two-arm, pilot randomised controlled trial. Patients who had a general surgery procedure were recruited from a tertiary hospital between October 2020 and January 2021. Patients were randomly assigned to either the standard education or the web-based education intervention.InterventionThe web-based education comprised of three components designed to enhance patients’ knowledge, skills and confidence to improve their engagement with self-care, and the ability to detect any postoperative issues that can arise during the postdischarge period.Main outcomes and measuresThe primary outcome was feasibility in terms of recruitment, randomisation, retention and treatment fidelity related to intervention delivery, adherence and satisfaction. Secondary outcomes were patient activation, self-care ability and unplanned healthcare utilisation.ResultsEighty-five patients were recruited and randomised (42 control; 43 intervention). Twenty-three (27%) were lost to follow-up. All patients received their group allocation as randomised and all patients in the intervention group received the web-based education prior to discharge. Postdischarge, patients accessed the education an average of 3 times (SD 3.14), with 4 minutes (SD 16) spent on the website. 28 (97%) of the intervention patients found the content easy to understand, 25 (86%) found it useful and 24 (83%) were satisfied with its content. There was a significant association between the intervention and patient activation (F(1,60)=9.347, p=0.003), but not for self-care ability and unplanned healthcare utilisations.ConclusionThis pilot study demonstrated the feasibility of implementing a web-based education programme. There was a high number of participants lost to follow-up, requiring additional attention in the design and implementation of a larger trial.Trial registration numberACTRN12620000389909p.

ObjectivesPhysical distancing as a non-pharmaceutical intervention aims to reduce interactions between people to prevent SARS-CoV-2 transmission. Intimate physical contact outside the household (IPCOH) may expand transmission networks by connecting households. We aimed to explore whether intimacy needs impacted adherence to physical distancing following lockdown in Britain in March 2020.MethodsThe Natsal-COVID web-panel survey (July–August 2020) used quota-sampling and weighting to achieve a quasi-representative population sample. We estimate reporting of IPCOH with a romantic/sexual partner in the 4 weeks prior to interview, describe the type of contact, identify demographic and behavioural factors associated with IPCOH and present age-adjusted ORs (aORs). Qualitative interviews (n=18) were conducted to understand the context, reasons and decision making around IPCOH.ResultsOf 6654 participants aged 18–59 years, 9.9% (95% CI 9.1% to 10.6%) reported IPCOH. IPCOH was highest in those aged 18–24 (17.7%), identifying as gay or lesbian (19.5%), and in steady non-cohabiting relationships (56.3%). IPCOH was associated with reporting risk behaviours (eg, condomless sex, higher alcohol consumption). IPCOH was less likely among those reporting bad/very bad health (aOR 0.54; 95% CI 0.32 to 0.93) but more likely among those with COVID-19 symptoms and/or diagnosis (aOR 1.34; 95% CI 1.10 to 1.65). Two-thirds (64.4%) of IPCOH was reported as being within a support bubble. Qualitative interviews found that people reporting IPCOH deliberated over, and made efforts to mitigate, the risks.ConclusionsGiven 90% of people did not report IPCOH, this contact may not be a large additional contributor to SARS-CoV-2 transmission, although heterogeneity exists within the population. Public health messages need to recognise how single people and partners living apart balance sexual intimacy and relationship needs with adherence to control measures.

BackgroundThe efficacy of performing a restorative proctocolectomy and J-pouch ileoanal anastomosis without diverting ileostomy in children with inflammatory bowel disease has been a longstanding debate. A systematic review and meta-analysis is presented comparing the occurrence of postoperative complications in children who underwent either the pouch-anal anastomosis (IPAA) with ileostomy (diverted) versus the undiverted procedure.MethodsRecords were sourced from CINAHL, CENTRAL, EMBASE and MEDLINE databases. Studies followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and compared postoperative complications in pediatric patients diagnosed with inflammatory diseases aged less than 18 years who underwent J-pouch with ileostomy versus without ileostomy. The primary outcome was the occurrence of postoperative leaks, and the secondary outcomes were presence of postoperative small bowel obstruction (SBO), pouchitis, stricture and fistula complications. A random-effects meta-analysis was used.ResultsTwenty-three observational studies in the systematic review were included with 658 patients (83% diverted, 17% undiverted). Pooled estimates showed no difference in occurrence of leaks in children who underwent J-pouch/IPAA with ileostomy versus without (odds ratio (OR) 0.54, 95% confidence interval (CI) 0.17 to 1.64, I2=16%). There was no difference in the occurrence of SBO, pouchitis or strictures in children who underwent J-pouch/IPAA with ileostomy versus without (SBO: OR 2.27, 95% CI 0.52 to 9.92, I2=0%, pouchitis: OR 1.76, 95% CI 0.95 to 3.24, I2=0%, strictures: OR 2.72, 95% CI 0.44 to 16.69, I2=66%).ConclusionThe meta-analysis did not find differences in the occurrence of complications in pediatric patients who underwent the IPAA with ileostomy procedure versus without ileostomy.
Optimizing the parameters for force, temperature, and metal removal rate: a multi-feature fusion model for titanium alloy milling
Authors: Li Songyuan , Li Shuncai , Li Yuqing , Popov Eugene 
Published: February 2022

In the processing of titanium alloy, the milling parameters determine the process temperature and force. Increasing the milling temperature and force can affect the quality of the titanium alloy produced. In this study, we developed a multi-feature fusion model for high-quality titanium alloy workpieces. In the milling experiments with different milling parameters, an infrared thermal imager and a three-dimensional dynamometer were used to collect the time-domain signals for temperature near the tip of the milling cutter and the milling force. Based on the experimental data, a multi-feature fusion model was established with the milling temperature, milling force, and metal removal rate as the targeted variables, and the milling parameters as the optimized parameters. Based on the particle swarm optimization algorithm, the optimal milling parameters within the test parameters were resolved using the multi-feature fusion model. The results show that: within the milling parameter range of the experimental design, the optimal solutions for the milling parameters are: milling speed of 22.14 m/min; feed speed of 8.25 mm/min; milling depth of 1.36 mm. The multi-feature fusion model resulted in lower milling temperature and force, and provides theoretical guidance for scientifically designing the parameters for the milling process.
Retesting the no-hair theorem with GW150914
Authors: Wang Ke 
Published: February 2022

AbstractFor a distorted black hole (BH), its ringdown waveform is a superposition of quasi-normal modes (QNMs). In general relativity (GR), the lower order QNM frequencies and damping rates can be well approximated by a polynomial of BH’s dimensionless spin and overall scaled by BH’s mass. That is to say, we can test the no-hair theorem of BH in GR model-independently by allowing not only an overall fractional deviation (as M. Isi et al. did) but also a set of fractional deviation for every coefficient. In the paper, we will apply the latter method to retest the no-hair theorem with GW150914 and probe hairs’ behaviors if hairs exist. Eventually, we find the data favors GR.

In this paper, we analyze the wormhole solutions in [Formula: see text] gravity. Specifically we sought for wormhole geometry solutions for the following three shape functions: (i) [Formula: see text], (ii) [Formula: see text] and (iii) [Formula: see text], under some legitimate physical conditions on the parameters as well as constants involved here with the shape functions. It is observed from the graphical plots that the behavior of the physical parameters are interesting and viable.

Published: February 2022

Background: Soft tissue sarcomas (STS) are rare, and little is known about the factors that affect the delays in the initial treatment. The aim of this study is to quantify the period between onset of symptoms and start of treatment of STS and determine the factors affecting delays in initial treatment.Methods: This is a retrospective study of all STS treated in our institution between October 2009 and March 2019. We analysed patient record to determine the period from onset of symptoms to start of initial treatment. We also collected data with regard to patient characteristics and features of the tumour. Tumours were classified into upper extremity, lower extremity, trunk and others based on location of the tumour. Statistical tests were done to identify factors that affected delay in initial treatment.Results: The study included 134 patients (76 male and 58 female) with STS with an average age of 56.6 years. The tumours involved the upper extremity in 20 patients, lower extremity and trunk in 50 patients each and other areas in 14 patients. The most frequent histological subtypes were liposarcomas (n = 31, 23.5%) and undifferentiated pleomorphic sarcomas (n = 24, 18.2%). Initial treatment was delayed by an average of 9.9 months for all groups. The period of treatment delay for tumours involving the upper extremity was shorter (7.9 months) and these tumours were smaller at initial presentation (57.6 mm) compared to tumours in other locations (p < 0.05). Other factors that were positively associated with treatment delays were a history of diabetes mellitus (p = 0.037) and smoking (p = 0.026).Conclusion: Patients with upper-extremity STS may have the benefit of a relatively better prognosis as they present earlier and with a smaller tumour. In addition, factors, such as diabetes and smoking, which indicate a low interest in health also influenced the delay in the initial treatment.Level of Evidence: Level III (Therapeutic)

Published: February 2022

Background: The outcomes of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) compared to the trapeziectomy (T) alone or in combination with tendon interposition (TIA) in the treatment of osteoarthritis (OA) of the carpometacarpal joint (CMCJ) of the thumb are still debated. The aim of this study is to conduct a meta-analysis to determine whether the outcomes of LRTI were better compared to T or TIA.Methods: A meta-analysis of randomised trials that included the outcomes of patients with thumb CMCJ OA that underwent LRTI, T or TIA with at least 1 year follow-up. The outcomes included number of patients with pain 1 year after surgery (NPP), Visual Analog Scale for Pain (VAS Pain), key pinch strength, patient reported outcome measurements (PROMs) and number of adverse effect (AEs). The effect was assessed using mean difference for quantitative variables (VAS pain and key pinch), standardised mean difference for PROMs and relative risk for binary variables (NPP and AEs).Results: Seven studies met the inclusion criteria (857 participants: 438 LRTI vs 419 T/TIA). We did not find significant differences between LRTI and T/TIA in NPP, VAS pain, key pinch at 1 year and 5 years or more, PROMs, and AEs at 1 year and at 5 years or more after surgery.Conclusions: The outcomes of LRTI are not superior to T or TIA in the treatment of OA of the thumb CMCJ.Level of Evidence: Level I (Therapeutic)

Published: February 2022

Background: The standard cross-finger flap (CFF) and laterally based thenar flap (LTF) are the time-tested modalities of fingertip reconstruction. We were unable to find any studies that have compared these two flaps for fingertip reconstruction. The aim of this study is compare the outcomes of these two flaps at 11 months after fingertip reconstruction. Methods: This is a prospective study of 40 patients with fingertip amputation who underwent reconstruction with either a standard CFF or an LTF. Data with regards to the patient, the injury, treatment and complications were recorded. Patients were followed up weekly for the first 6 weeks and at 3, 6, 9 and 12 months thereafter. Outcome measures assessed at final follow-up included passive range of motion, two-point discrimination, cold intolerance, patient aesthetic satisfaction with the flap, assessment of donor scar and psychosocial benefit. Results: Fingertip reconstruction was done with 23 CFFs and 17 thenar flaps. Partial necrosis was noted in three thenar flaps. The mean follow-up period was 11 months. The sensory recovery and aesthetic satisfaction with the flap were greater in thenar flap group. There were no differences between the two flaps in the other outcome measures. Conclusions: Sensory recovery and aesthetic outcomes were better in thenar flaps compared to a CFF. However, thenar flap were associated with a greater incidence of partial flap loss.

Authors: CHEN Wei F. , KIM Bong-Sung , LIN Yu-Te 
Published: February 2022

Peritendinous adhesions represent a common problem without a satisfactory solution despite several studies. We have been using a conventional silicone Penrose drain in patients undergoing tenolysis in the hand since 2006. The Penrose drain is wrapped around the segment of the tendon after tenolysis. Therapy is started on the second post-operative day and the Penrose drain removed after one week in the outpatient clinic. We have had good outcomes with this technique. It is inexpensive, readily available and effective. Level of Evidence: Level V (Therapeutic)
The structure and tectonics of the Guyana Basin
Authors: Trude James , Kilsdonk Bill , Grow Tim , Ott Bryan 
Published: February 2022

Abstract

The Guyana Basin formed during the Jurassic opening of the North Atlantic. The basin margins vary in tectonic origin and include the passive extensional volcanic margin of the Demerara Plateau in Suriname, an oblique extensional margin inboard at the Guyana–Suriname border, a transform margin parallel to the shelf in NW Guyana, and an ocean–ocean margin to the NE, which morphed from transform to oblique extension. Plate reconstructions suggest rifting and early seafloor spreading began with NNW/SSE extension (
c.
190–160 Ma) but relative plate motion later changed to NW/SE. The fraction of magmatic basin floor decreases westwards and the transition from continental to oceanic crust narrows from 200 km in Suriname to less than 50 km in Guyana. The geometry and position of the onshore Takutu Graben suggest it formed a failed arm of a Jurassic triple junction that likely captured the Berbice river during post-rift subsidence and funneled sediment into the Guyana Basin. Berriasian to Aptian shortening caused crustal-scale folds and thrusts in the NE margin of the basin along with minor inversions of basin margin and basin-segmenting faults. Stratigraphically trapped Liza trend hydrocarbon discoveries are located outboard of inverted basement faults, suggesting a link between transform margin structure and their formation.
Exploring the predictive power of seismic geomorphology to assess sedimentary characteristics of gravity-flow deposits: examples from offshore East and West Africa reservoirs
Authors: Scarselli Nicola 
Published: February 2022

Abstract
This research seeks to test the hypothesis that the rheology of submarine gravity-flows influences the planform geometry of associated fan lobe deposits. If this control exists, seismic geomorphology has the potential to predict the sedimentary characteristics of these deposits by analysing relatively simple seismic outputs such as time structure maps and amplitude maps. This predictive power could potentially aid the identification of prospective reservoirs through automated processes of seismic interpretation. In this work, Upper Cretaceous and Neogene deep-water reservoirs from East and West Africa with porosity in excess of 20% and multi-Darcy permeability were analysed. The overall external geometry of the reservoirs was described by integrating seismic amplitude extractions, structure and isochron maps derived from high-quality 3D seismic data. The maps were generated from detailed interpretation of the top and base reservoir reflections. Core photos of the reservoirs were integrated into the seismic project and their examination allowed the identification of dominant sedimentary facies, enabling a proposal for the classification of these deposits in terms of flow processes. The research indicates that the confinement of flows exerts an obvious control on the shape of the deposits and results in sedimentary bodies with marked elongation at the seismic scale. However, analysis of the reservoirs at the core scale indicated that they are dominated by massive, poorly sorted, medium- to coarse-grained sandstones, commonly with floating oversize clasts, as well as beds with disrupted laminae and sandy conglomerates. These characteristics may indicate ‘depositional freezing’ from high-density flows with yield strength, which may also have contributed to the limited lateral spread of the deposits analysed. The research also highlights the importance of the non-unique relationship between sedimentary processes and external geometries of the resulting deposits at the seismic scale. This means that deposits with similar geometries may have markedly different sedimentary characteristics. This work highlights the increasing importance of integrating detailed seismic geomorphology studies with an accurate examination of core data to validate models of gravity flow processes and test their predictive value.

Objectives. The NUTRIC (nutrition risk in the critically ill) score and the modified NUTRIC score are two scoring systems that show the nutritional risk status and severity of acute disease of patients. The only difference between them is the examination of interleukin-6 (IL-6) level. The aim of this study was to investigate whether or not the NUTRIC score is superior to the mNUTRIC score in the prediction of mortality of patients with COVID-19 followed up in the Intensive Care Unit (ICU). Material and Method. This retrospective study included 322 patients followed up in ICU with a diagnosis of COVID-19. A record was made of demographic data, laboratory values, clinical results, and mortality status. All the data of the patients were compared between high and low variations of the NUTRIC score and the mNUTRIC score. Results. A high NUTRIC score was determined in 62 patients and a high mNUTRIC score in 86 patients. The need for invasive mechanical ventilation, the use of vasopressors in ICU, the development of acute kidney injury, and mortality rates were statistically significantly higher in the patients with high NUTRIC and high mNUTRIC scores than in those with low scores (

p

= 0.0001 for all). The AUC values were 0.791 for high NUTRIC score and 0.786 for high mNUTRIC score (

p

= 0.0001 for both). No statistically significant difference was determined between the two scoring systems. Conclusion. Although the NUTRIC score was seen to be superior to the mNUTRIC score, no statistically significant difference was determined. Therefore, when IL-6 cannot be examined, the mNUTRIC score can be considered safe and effective for the prediction of mortality in COVID-19 patients.
