The light curve simulations of the 2021 anomalous event in SS Cygni
Authors: Kimura Mariko , Osaki Yoji 
Published: January 2023

Abstract
The prototype dwarf nova SS Cyg unexpectedly exhibited an anomalous event in its light curve in the early few months of 2021 in which regular dwarf nova-type outbursts stopped, and only small-amplitude fluctuations occurred. Inspired by this event, we have performed numerical simulations of light curves of SS Cyg by varying mass transfer rates and varying viscosity parameters in the cool disk. We have also studied the effect of gas-stream overflows beyond the outer disk edge in the light curve simulations. We have confirmed that the enhanced mass transfer is not likely to be responsible for the 2021 anomalous event or its forerunner. We have found that the enhancement of the viscosity in the disk may reproduce the forerunner of that event but may not be sufficient to explain the 2021 anomalous event, although the latter result might be particular to the thermal equilibrium curve we used. Within our simulations, a model of the gas-stream overflow with a slightly higher mass transfer rate than that of our standard model reproduces light curves similar to the 2021 anomalous event. We suggest that the gas-stream overflow is necessary to reproduce that event. The gas-stream overflow may also be responsible for the abnormally high X-ray flux during the normal quiescent state in SS Cyg.

Published: January 2023

Introduction: Restless legs syndrome (RLS) is a neurological sensory-motor disorder that is observed as an unpleasant sensation in the legs, especially when sitting or lying down and at rest. This study aimed to determine the prevalence RLS and its related factors among older adults in Eslamabad-e-Gharb, Kermanshah province, Iran in 2021.

Methods: Totally, 240 elderlies entered the study using two stages random sampling. The instruments used in the study included the International RLS Questionnaire, Pittsburgh Sleep Quality Index, Mind Wandering Questionnaire, Epworth Sleepiness Scale and Pain Self-efficacy Questionnaire.

Results: Symptoms of RLS were mild in 68.3% of the participants and severe in 14.2% of them. There was a statistically significant relationship between RLS and sleep quality (p = 0.001) and daily drowsiness (p = 0.034). The chance of developing RLS in the group with poor sleep quality was 22% higher than the group with good sleep quality (OR = 1.22). Also, people with drowsiness were 13% more likely to develop RLS than others (OR = 1.131), and in the age group of 71-80 years and over 80 years, 6% and 2% higher than the 60-70 years respectively (OR = 1.068 and 1.023). No statistically significant relationship was found between RLS with mind wandering and pain self-efficacy.

Conclusion: Due to the high prevalence of RLS and its relationship with sleep quality and daily drowsiness among older adults, implementation of RLS screening to identify patients to prevent sleep disorders seems necessary. The relation of RLS with mind wandering and pain self-efficacy need further studies.
Factors Influencing the Adoption of Mobile Health Monitoring and Care Systems by the Elderly Living at Home in South Africa
Authors: Fotoyi Yolande , Cilliers Liezel 
Published: January 2023

Introduction: Technology can improve the health care outcomes of the elderly. However, there are many barriers to the adoption of mobile monitoring and care systems (MMCs) by the elderly reported in literature. The main purpose of this research was to investigate why elderly people do not adopt MMCs to improve the quality of their health care.

Methods: The study made use of semi-structured interviews to collect data in the Buffalo City Metropolitan Municipality, South Africa. The study sample consisted of 15 purposively chosen study participants, representing a diverse racial profile, in order to investigate the adoption of MMCs of the elderly in their home environment. The interviews were analysed thematically.

Results: The study found that social challenges like technology anxiety, the intrusive nature of the technology and attitude towards the technology will affect adoption of MMCs. Government need to address the standardisation, data governance and interoperability of the systems. The cost of MMCs were seen as an inhibitor, but could be off set against the perceived return on investment of health care. While the elderly acknowledged that MMCs can improve their independence, the design of the MMCs and training to use it was identified as barriers to the adoption.

Conclusion: The study, therefore, recommends collaborative engagements amongst government, business and the elderly to facilitate the adoption of MMCs in the elderly community to improve the quality of health care.

Published: January 2023

Abstract
The consequences of myocardial infarction (MI) are an increasing problem worldwide. Despite spectacular progress in the invasive treatment of ischemic heart disease, the ability to limit the ischemia-reperfusion (I/R) injury remains largely unrealized. Recent studies have shown that stimulation of opioid receptors may confer a cardioprotective effect against I/R injury. Levosimendan, the inodilator, is indicated for the short-term treatment of acutely decompensated heart failure. We tested the hypothesis that levosimendan may provide cardioprotection in the opioid-like mechanism in the human myocardium.

OBJECTIVE
Sacroiliac joint (SIJ) fusion utilizing intraoperative navigation requires a standard reference frame, which is often placed using a percutaneous pin. Proper placement ensures the correct positioning of SIJ fusion implants. There is currently no grading scheme for evaluation of pin placement into the pelvis. The purpose of this study was to evaluate the occurrence of ideal percutaneous pin placement into the posterior ilium during navigated SIJ fusion.

METHODS
After IRB approval was obtained, electronic medical records and intraoperative computed tomography images of patients who underwent navigated SIJ fusion by the senior author between October 2013 and January 2020 were reviewed. A pin placement grading scheme and the definition of "ideal" placement were developed by the authors and deemed acceptable by fellow attending surgeons. Six attending surgeons completed two rounds of pin placement grading, and statistical analysis was conducted.

RESULTS
Of 90 eligible patients, 73.3% had ideal pin placement, 17.8% medial/lateral breach, and 8.9% complete miss. Male patients were 3.7 times more likely to have ideal placement than females (p < 0.05). There was no relationship between BMI, SIJ fusion laterality, or pin placement laterality and ideal placement. Interobserver reliability was 0.72 and 0.70 in the first and second rounds, respectively, and defined as "substantial agreement." Intraobserver reliability ranged from 0.74 (substantial agreement) to 0.92 (almost perfect agreement).

CONCLUSIONS
Nonideal pin placement occurred in 26.7% of cases, but a true "miss" into the sacrum was rare. Ideal pin placement was more likely in males and was not associated with BMI, SIJ fusion laterality, or pin placement laterality. The grading scheme developed has high intraobserver and interobserver reliability, indicating that it is reproducible and can be used for future studies. When placing percutaneous pins, surgeons must be aware of factors that can decrease placement accuracy, regardless of location.

Published: January 2023

Acellularized nerve allografts (ANAs) have been developed as substitutes for nerve autograft to promote nerve regeneration after surgical repair. In this video, the authors demonstrate operative techniques for using ANAs to repair potentially functional nerve fascicles during tumor resection. A 67-year-old female with schwannomatosis requested resection of a painful enlarging mass of the left ulnar nerve proximal to the elbow. During surgery, neuromonitoring suggested that fascicles entering the tumor could be functional. Therefore, nerve allograft was used to repair the transected fascicles. The patient recovered with full strength and sensation in the ulnar distribution, with resolution of her preoperative symptoms.

Published: January 2023

Neonatal brachial plexus palsy describes injury to the brachial plexus in the perinatal period, resulting in motor and sensory deficits of the upper arm. Nerve reconstruction, including graft repair and nerve transfers, can be used to restore function in patients whose injury does not respond to conservative management. Despite the availability of these techniques, 30%–40% of children have lifelong disability, reflecting a 10-fold underutilization of surgery. Here, the authors demonstrate a supraclavicular approach for brachial plexus exploration, as well as a spinal accessory to suprascapular nerve transfer for restoration of shoulder abduction and external rotation.

Published: January 2023

A 48-year-old female was admitted to the authors’ department due to hand weakness as a consequence of C8, T1 root injury. Eight months earlier, the patient had been treated by a pulmonary surgeon due to an expansive lesion near the apex of the right lung, which resulted in right lower brachial plexus palsy. Postoperative pathohistological findings indicated that the lesion was nerve schwannoma. The diagnostic process included physical examination, electromyoneurography, and MRI. A distal nerve transfer (pronator teres–anterior interosseus nerve [PT-AIN], supinator–posterior interosseus nerve [SUP-PIN]) was performed in order to restore hand function.

This is a video demonstration of hemihypoglossal-facial neurorrhaphy. Any irreversible facial palsy more than House-Brackmann grade II is aesthetically problematic. Also, the functional and psychological impact associated with a higher grade of facial palsy is even worse.
In this video, the procedure is demonstrated in a female patient with irreversible grade VI facial palsy and corneal opacity due to exposure keratitis 1 year following surgical excision of cerebellopontine angle (CPA) schwannoma. Postoperative outcomes are shown in another patient who underwent a similar procedure for establishing outcomes. The nasolabial fold and eye closure symmetry can be achieved with minimal or no hypoglossal morbidity.

Published: January 2023

Smooth symmetric facial muscle function is important for social interactions. When lesions of the facial nerve occur, achieving complete restoration of balanced and spontaneous facial function can be challenging. In this video, the authors demonstrate the surgical details and long-term follow-up of a masseter-to-facial nerve transfer in a 3-year-old girl who had insidious onset of a left facial palsy due to a facial nerve schwannoma. After resection, she underwent distal nerve repair with a masseter-to-zygomatic branch transfer. She demonstrated decreased lagophthalmos and good activation and excursion on the left side with near symmetry to the right side, but lacked left frontalis function.

Distal anterior interosseous nerve to ulnar nerve motor branch reverse end-to-side transfer in a case of severe ulnar neuropathy
Authors: Pathiyil Rajesh Krishna , Elzinga Kate , Umansky Daniel , Midha Rajiv 
Published: January 2023

Reverse end-to-side (RETS) distal transfer is gaining popularity in cases of proximal nerve damage with the nerve in continuity, allowing the nerve to potentially retain its ability to regenerate and recover. While preserving the original axon pool, RETS could provide an additional pool of motor axons and/or possibly "babysit" the muscle endplates and distal denervated nerve Schwann cells until reinnervation from the original pool occurs. The authors present a video demonstrating anterior subcutaneous transposition of the ulnar nerve at the elbow coupled with a distal anterior interosseous nerve to ulnar nerve RETS in a case of severe posttraumatic ulnar neuropathy at the elbow.

Published: January 2023

Cervical dystonia (spasmodic torticollis) is a condition that involves sustained, involuntary contraction of neck and shoulder muscles, leading to abnormal movements and head posture. The authors present the case of a 41-year-old man with severe right rotational torticollis for 1.5 years due to predominant right cervical paraspinal and left sternocleidomastoid muscle hyperactivity. Following failed medical management, the patient elected to undergo surgical treatment for his torticollis. In their video, the authors discuss the steps of selective denervation using a modified Bertrand procedure, highlighting the associated anatomy and surgical planes. At the 1.5-year follow-up, the patient had no pain and his head position remained straight.

C1 Fixation by (Fc)5µ Fragment
Authors: Bubb Martin O. , Conradie Jan D. 
Published: January 2023

Abstract
The ability of C1 to bind to (Fc)5µ-fragment of a monoclonal IgM was determined by means of a hemolytic C1-inhibition assay. (Fc)5µ-fragments were produced by trypsin digestion at five different temperatures ranging from 54 to 62°C (2°C increments) and were purified by immunoadsorption through a column of monospecific anti-Fabµ and by molecular exclusion chromatography. Analytical ultracentrifugation showed the final preparations to be free of aggregates. A plot of µg (Fc)5µ required to inhibit 50% of available C1 (Z = 1 to 1.5) vs temperature of production of the fragment, yielded a curve with a minimum (5 µg) at 58 to 60°C. Upon mild reduction and alkylation of these (Fc)5µ's their C1-fixing capacity reverted to being approximately the same (60 µg) irrespective of temperature of production. (Fc)5µ was also prepared at 25°C in the presence of 5 M urea, purified by immunoadsorption as before and aliquots then exposed to temperatures ranging from 40 to 70°C (5°C increments) for 15 min.
