Authors: Mi Shiqing , Hu Junshan , Xuan Shanyong , Yu Jiali , Tian Wei 
Published: December 2022

This paper reports an experimental study on the forming mechanism and bearing behavior of single-lap composite riveted joints with different hole diameters (4.82 mm and 4.9 mm) and squeeze forces (15 KN, 18 KN, 20 KN, and 23 KN). Pressure riveting and tensile tests are conducted to composite riveted joints to obtain the joint interference, joint stiffness and bearing strength needed to quantitatively evaluate their deformation features and mechanical properties. Furthermore, microscopic studies on damaged areas using applying ultra-depth three-dimensional microscope to monitor damage evolution are conducted to comprehend the joint shear failure mechanism. Results show that the hole diameter and riveting force have a significant effect on the performance of the joint. The forming damage occurs mainly in the hole wall near the driven head and is dominated by fiber crushing and interfacial shear cracks. The radial expansion of the rivet shank is not uniform under the riveting force and the whole is drum shaped. But the hole expansion of the joint at 4.82 mm hole diameter is more uniform than 4.9 mm, which would lead to better joint stiffness and bearing strength. Moreover, high interference fit would cause the shear fracture of the rivet, while lower interference joints are dominated by compression-pull mixed failure. In general, the size of interference fit is an unneglectable factor in the composite riveted joints that should be thoroughly investigated.

Introduction Chemotherapy-induced nausea and vomiting (CINV) are two serious adverse effect of cancer chemotherapy. The objectives of this study are to assess patient satisfaction with antiemetics prescribed, incidence of nausea and vomiting in cancer patients, and the effectiveness of antiemetic regimens in reducing CINV. Methods This is a prospective observational cross-sectional patient survey study, conducted between January and July 2021 in the oncology center at King Saud University Medical City, Riyadh, Saudi Arabia. A suitable, data entry form was designed to collect data including patient demographics, cancer type, antiemetics prescribed, chemotherapy regimen, and incidence of CINV. Results The sample comprised 283 cancer patients with a mean age of 47.7 (±14.6) years. Colorectal and breast cancer ( n = 67; 23.6%, for each) were the two most common diagnoses. Among the patients who received chemotherapy, most patients ( n = 144; 50.8%) received chemotherapy that was classified as highly emetogenic, and 139 (49%) received moderately emetogenic chemotherapy. Antiemetics were given to control CINV before chemotherapy administration (as prophylaxis) were either combination therapy (170 patients (60.0%) received four classes of antiemetics, 72 (25.4%) received three classes; and 31 (10.9%) received two classes) or monotherapy (six patients (2.1%) received one drug). Four patients (1.4%) did not receive any antiemetic medication. Antiemetics given to control CINV after chemotherapy administration (for delayed CINV) were also either in combination (151 patients (53.3%) received three classes of antiemetics and 94 (33.2%) received two classes) or as monotherapy, where 27 patients (9.5%) received one medication. Eleven patients (3.8%) did not receive any antiemetic. The incidence rates for acute and delayed nausea after chemotherapy treatment were 32.1% and 30.7%, respectively; and those for acute and delayed vomiting were 13.4% and 10.2%, respectively. Acute nausea was much more frequent than vomiting. Conclusion The incidence of CINV was relatively high, and patients who received chemotherapy continued to experience nausea and vomiting despite receiving antiemetic treatment. This demonstrates that antiemetic regimens used are not effective in preventing CINV.

Objective: Low primary patency rate is a major problem of radio-cephalic arteriovenous fistula (RC-AVF) creation. Radial artery deviation and reimplantation (RADAR) is associated with low juxta-anastomotic stenosis rate. However, inflow artery stenosis is prominent with RADAR. To further reduce injury to veins and arteries during operation, a modified no-touch technique (MNTT) was used to create RC-AVF. Methods: We retrospectively reviewed our prospectively maintained database of patients with end-stage renal disease (ESRD)s undergoing RC-AVF creation for hemodialysis using either the MNTT between January 2021 and January 2022 (MNTT group) or conventional surgical procedure ( end-to-side vein-to-artery anastomosis) between October 2016 and October 2017 (Control group). Patients who chose to undergo RC-AVF surgery underwent standardized preoperative mapping and postoperative fistula evaluations using duplex ultrasound. Additionally, 4D flow MRI data were used to visualize and quantify the hemodynamics of one RC-AVF by MNTT. Outcomes included primary patency, juxta-anastomotic stenosis, and maturation rates. Results: Forty patients underwent RC-AVFs by MNTT, compared to 60 patients in the control group. The MNTT group had a higher primary unassisted patency rate than the control group ( p = 0.038). Juxta-anastomotic stenosis (all on the cephalic vein) occurred in 4 (10%) patients who underwent MNTT. RC-AVF maturation rates after 3 months were not different between both groups (maturation rate: 90% and 81.7% in the MNTT and control groups, respectively, p = 0.253). COX regression showed that both conventional AVF surgery ( p = 0.031) and smaller cephalic vein diameter ( p = 0.034) were associated with higher odds of RC-AVF failure. The AVF flow within the proximal vein remained helical during cardiac cycle. The distribution of wall shear stress (WSS) and oscillatory shear index (OSI) differed from that of conventional surgical AVF. Conclusion: RC-AVF by MNTT increases primary patency rate and decreases juxta-anastomotic stenosis rate. The improvement in hemodynamics may be one of the important reasons for the better patency rate of in the RC-AVF by MNTT group.

Published: December 2022

Context: Therapeutic exercise is considered the mainstay in the management of rotator cuff-related shoulder pain (RCRSP). Manual therapy (MT) interventions have also shown to be effective in RCRSP. However, the benefits of adding MT along with exercise interventions for the management of RCRSP remain unknown. Objective: To evaluate the additional benefits of MT with exercise compared with exercise in isolation for the management of RCRSP. Data Sources: A search of PubMed, Scopus, PEDro, and EBSCO from the inception date of each database through April 20, 2022, was conducted for randomized trials comparing the additional effects of MT in exercise interventions compared with exercise alone for pain management and function in patients with RCRSP. Standardized mean differences (SMDs) and 95% CIs were calculated using a random-effects inverse variance model according to the outcome of interest and comparison group. Methodological quality was assessed with PEDro and quality of evidence with the grading of recommendations assessment, development and evaluation approach. Study Design: Meta-analysis of randomized controlled trials. Level of Evidence: Level 2. Results: Twelve articles were found eligible and 8 of them demonstrated high methodological quality. Eleven articles were included for quantitative analysis. Pain with movement was not significantly different between MT and exercise versus exercise alone (SMD [95% CI] = −0.15 [−0.41 to 0.12]; I2 = 0%), whereas pain at rest was significantly improved in the groups that used exercise only with a moderate effect size (SMD [95% CI] = 0.47 [0.04 to 0.89]; I2 = 75%). Furthermore, shoulder function was not significantly different between MT and exercise versus exercise alone in the short term (SMD [95% CI] = 0.23 [−0.22 to 0.69]; I2 = 88%) or the long term (SMD [95% CI] = −0.02 [−0.21 to 0.16]; I2 = 2%). Conclusion: Adding MT to exercise interventions for the management of RCRSP is not more effective than exercise alone for pain and function in adult patients.

Published: December 2022

Background: Risk for lower extremity musculoskeletal injury increases after sport-related concussion (SRC) and may result from unresolved motor control deficits. Muscle weakness is a deficit that could contribute to musculoskeletal injury risk. Hypothesis: Athletes with SRC will demonstrate quadriceps and hamstring muscle weakness at the time of return to sport and 30 days later compared with controls. Study Design: Prospective matched cohort. Level of Evidence: Level 3. Methods: A total of 31 athletes with SRC (CONCUSSION) were matched by sex, age, and activity level to controls (CONTROL). Testing was conducted at initial assessment and 30 days later; initial assessment in CONCUSSION occurred when cleared for return to play. Isokinetic testing assessed quadriceps and hamstring strength of the dominant and nondominant legs at 60 and 180 deg/s. Peak torque values were normalized to body mass (N-m/kg). Data were analyzed with repeated measures general linear models (group × time), and effect sizes were calculated. Results: Analysis at 60 deg/s included 26 matched pairs (15 male per group) and at 180 deg/s included 30 matched pairs (17 males per group). Time from concussion to initial assessment was 21.3 (7.8) mean (standard deviation) days. No significant interactions or main effects were detected ( P > 0.05). Across muscle groups, legs, and testing speeds, effect sizes at initial assessment were small ( d = 0.117 to 0.353), equating to a strength deficit in CONCUSSION of 0.04 to 0.18 N-m/kg, and effect sizes were further reduced at 30-day follow-up (d = −0.191 to 0.252). Conclusion: In athletes with SRC, quadriceps and hamstring strength were decreased only minimally at return to play compared with controls and the difference lessened over 30 days. Clinical Relevance: Strength deficits may not be a major contributor to increased lower extremity musculoskeletal injury risk after SRC. Strength training could be implemented before return to play after SRC to mitigate any strength deficits.
All Arthroscopic Suprapectoral Biceps Tenodesis
Authors: McCahon Joseph A. S. , Albana Mohamed F. , Szukics Patrick F. , McMillan Sean 
Published: December 2022

Background: Biceps tendinopathy can have significant clinical manifestations in active patients. Failure to achieve resolution of symptoms through nonsurgical modalities oftentimes results in surgical intervention. The 2 most common surgical treatment options for tendinopathy of the long head of the biceps tendon (LHBT) are tenotomy and tenodesis. Both modalities have shown efficacy within the literature; however, tenodesis of the LHBT has many advantages to tenotomy. Indications: Subgroove tenodesis eliminates the potential pain generation within the bicipital groove. Despite recent proof of clinical equivalence in open versus arthroscopic tenodesis, there has been increasing interest in all-arthroscopic biceps tenodesis techniques in hopes of minimizing surgical exposure, decreasing the rate of potential neurovascular compromise, and decreasing the time to recovery. Technique: We present an all-arthroscopic technique for a subgroove biceps tenodesis using a unicortical tensionable button. The proximal biceps anchor is held in place at its insertion site with a spinal needle to prevent retraction. The lateral portal is redirected into the subdeltoid space. A novel suprapectoral biceps portal, called the Willingboro portal, is placed percutaneously 2 cm above the pectoralis tendon. Onlay fixation of the LHBT is performed proximal to the pectoralis major muscle insertion using a unicortical button. Postoperative protocol is similar to other fixation constructs. Results: Numerous arthroscopic biceps tenodesis techniques have been described with good success; however, an all-arthroscopic suprapectoral tenodesis is attractive to many reasons. The unicortical button construct shows similar load to failure strength as the bicortical button construct, both of which are greater than all other constructs described in the literature. Discussion/Conclusion: Arthroscopic subgroove biceps tenodesis using a unicortical button technique is a viable option that avoids the complications associated with an open axillary incision as well as persistent groove pain. Anchoring the biceps tendon prior to tenotomy allows for preservation of tendon length, limiting the complications associated with tendon retraction with anticipated improvement in patient-reported outcomes. The unicortical button is known to have a similar strength profile as the bicortical button technique, which is greater than other techniques described in the literature. Future studies should be aimed at assessing long-term patient-reported outcomes.

AbstractBackgroundAs literature largely focuses on long-term outcomes, this study aimed at elucidating the perioperative outcomes of liver transplant patients receiving a graft from two groups of unconventional expanded criteria donors: brain dead aged > 80 years and cardiac dead.MethodsData of 247 cirrhotic patients transplanted at two high volume liver transplant centers were analysed. Confounders were balanced using a stabilized inverse probability therapy weighting and a propensity score for each patient on the original population was generated. The score was created using a multivariate logistic regression model considering a Comprehensive Complication Index ≥ 42 (no versus yes) as the dependent variable and 11 possible clinically relevant confounders as covariate.ResultsForty-four patients received the graft from a cardiac-dead donor and 203 from a brain-dead donor aged > 80 years. Intraoperatively, cardiac-dead donors liver transplant cases required more fresh frozen plasma units (P < 0.0001) with similar reduced need of fibrinogen to old brain-dead donors cases. The incidence of reperfusion syndrome was similar (P = 0.80). In the Intensive Care Unit, both the groups presented a comparable low need for blood transfusions, renal replacement therapy and inotropes. Cardiac-dead donors liver transplantations required more time to tracheal extubation (P < 0.0001) and scored higher Comprehensive Complication Index (P < 0.0001) however the incidence of a severe complication status (Comprehensive Complication Index  ≥ 42) was similar (P = 0.52). ICU stay (P = 0.97), total hospital stay (P = 0.57), in hospital (P = 1.00) and 6 months (P = 1.00) death were similar.ConclusionSelected octogenarian and cardiac-dead donors can be used safely for liver transplantation.
Comparison of response options and actual symptom frequency in the Japanese version of the Edinburgh Postnatal Depression Scale in women in early pregnancy and non-pregnant women
Authors: Suenaga Hiromi 
Published: December 2022

Abstract
Background
The positive predictive rate of the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS) is lower than those of other versions. This study aimed to confirm whether the EPDS Japanese version reflects actual symptom frequency and to examine the possibility of improving the positive predictive rate.

Methods
This is a methodological study aimed at improving the positive predictive value of EPDS. The participants were 63 non-pregnant and 382 pregnant women. They answered the 10 questions of the Japanese version of the EPDS and reported the specific number of days as the frequency. The EPDS score (EPDS-S) and the frequency score (FREQ-S) were calculated for three factors of emotion: anhedonia, anxiety, and depression.

Results
The positive rates of the EPDS-S and FREQ-S in pregnant women were 6% and 8%, respectively, which were lower than those in non-pregnant women (17%). On comparing the EPDS-S with the FREQ-S, a significant underestimation of frequency was observed in approximately 3% of pregnant women. The FREQ-S showed better internal consistency than the EPDS-S. Among the factors of emotion, women tended to rate anhedonia lower in the EPDS-S than in the frequency scale.

Conclusion
Pregnant women tended to report a lower frequency on the Japanese version of the EPDS than their actual symptom frequency, which was especially true for those with a desire to self-harm. The combined use of the FREQ-S and EPDS-S can prevent underestimation and help improve the detection rate of depression.

Published: December 2022

Abstract
Background
Non-clinical hospital staff were rarely studied despite their potential exposure to workplace stressors. We aimed to measure the prevalence of depression, anxiety, and stress (emotional distress symptoms) and determine their association with perceived job stress level and socioeconomic factors among non-clinical hospital staff.

Methods
This cross-sectional study was conducted in Ain-Shams University Hospitals from March to May 2019. Tools were the Arabic Depression, Anxiety, and Stress Scale-21, Workplace Stress Scale, and Socioeconomic status scale. Independent correlates were determined using multivariable ordinal regression.

Results
Out of 462 participants, 72.5% reported receiving insufficient income and 54.8% showed Effort-reward imbalance. Job stress was scored as severe/potentially dangerous by 30.1%. The prevalence of depression, anxiety, and stress were 67.5, 69.0, and 51.7%; and the severe/extremely severe levels were 20.8, 34.6, and 17.6% respectively. Across all the severity levels, the likelihood of depression, anxiety, and stress were progressively higher with more serious levels of income insufficiency [in debt versus able to save, OR:5.82 (95%CI:2.35–14.43), OR:3.84 (95%CI:1.66–8.91), and OR:3.01 (95%CI:1.20–7.55) respectively] and with higher job stress levels. Specifically, the likelihood of depression, anxiety, and stress increased by 74, 56, and 53% respectively with feelings of unpleasant/unsafe work conditions and by 64, 38, and 62% respectively with the presence of work-life conflict; while the likelihood of depression and stress increased by 32 and 33% respectively when there was difficult communication with superiors; and only the likelihood of depression increased by 23% with underutilization of skills.

Conclusion
Non-clinical hospital staff were commonly affected by emotional distress symptoms with high rates of severe/very severe levels, and they often considered their workplace stress as severe/potentially dangerous. Workplace stress and income insufficiency were strong correlates with emotional distress symptoms. Decreasing work-life conflict, enhancing leadership skills, and mitigation of the economic hardship are needed.
Hidden blood loss of minimally invasive hybrid lumbar interbody fusion: an analysis of influencing factors

Published: December 2022

Abstract
Background
Lumbar interbody fusion(LIF) is the leading way to treat Lumbar Degenerative Diseases(LDD). At present, there is a lack of research on the influencing factors of hidden blood loss in minimally invasive hybrid lumbar interbody fusion. This study comprehensively explores the definite factors affecting the hidden blood loss in minimally invasive hybrid lumbar interbody fusion.

Materials and methods
One hundred patients with Lumbar degenerative diseases who underwent minimally invasive hybrid lumbar interbody fusion in our center were included. Demographics, laboratory data, surgical data, and radiographic data were collected. The Gross equation and Sehat equation were used to calculate the estimated value of hidden blood loss. Multi-factor linear regression analysis was used to determine the influencing factors of hidden blood loss.

Result
We reviewed and collected 100 patients who underwent minimally invasive hybrid approach, mean age 65 ± 10 years, male: female 37:63; 17 patients of diabetes and 83 patients of non-diabetes; Total blood loss was 645.59 ± 376.37 ml, hidden blood loss was 421.39 ± 337.45 ml, the hidden blood loss percentage was 57 ± 26%. Results from the multi-factorial linear regression model: Diabetes (p < 0.05), hypertension (p < 0.05), psoas thickness (p < 0.05) and dorsal extensor group thickness (p < 0.05) were potential risk factors for postoperative hidden blood loss.

Conclusion
Although minimally invasive hybrid approach is minimally invasive surgery, there is still a significant amount of hidden blood loss. There is a greater risk of blood loss in diabetes, hypertension and preoperative MRI assessment of thickness of the psoas, thickness of the dorsal extensor group.
