ObjectiveTo investigate the effects of home‐based telerehabilitation based on the Internet‐based rehabilitation management system on hip function, activities of daily living and somatic integrative ability of elderly postoperative hip fracture patients.MethodsFrom June 2020 to November 2020, we recruited 58 elderly postoperative hip fracture patients and randomly assigned them to the telephone group (n = 29) and the telerehabilitation group (n = 29). Both groups received routine discharge instructions, and the former received telephone follow‐up after discharge, while the latter received remote rehabilitation based on the Internet‐based rehabilitation management system. The Harris hip score (HHS), functional independence measure (FIM), timed up‐and‐go test (TUG), and short physical performance battery (SPPB) were used to evaluate the patients' hip function, activities of daily living, and overall somatic ability.ResultsThere was no significant difference between the baseline data of the two groups before the intervention (P > 0.05); no matter after hip replacement or internal fixation, the HHS score and FIM score of both groups increased gradually with the postoperative time, and the scores in the telerehabilitation group were higher than those in the telephone group at 1 and 3 months after the intervention, and the difference was significant (P < 0.05); for patients after hip replacement, the TUG and SPPB scores in the telerehabilitation group were better than those in the telephone group at 3 months after the intervention, and the difference was significant (P < 0.05).ConclusionsThe Internet‐based rehabilitation management system applied to postoperative home rehabilitation of elderly hip fracture patients can improve the functional recovery of the hip joint and enhance the ability to perform activities of daily living and somatic integration to a certain extent. This seems to provide an effective option for conducting home rehabilitation.

BackgroundPeriprosthetic osteolysis is a serious complication following total hip arthroplasty (THA). However, most orthopedic surgeons only focus on bone loss and hip reconstruction. Thus, it was required to understand the treatment algorithm for periprosthetic osteolysis integrally.Case PresentationA 52‐year‐old Asian male presented with chronic hip pain. A mass appeared on the medial side of the proximal left thigh at more than 20 years after bilateral THA. Radiographs revealed catastrophic periprosthetic osteolysis, especially on the acetabular side. Large amounts of necrotic tissue and bloody fluids were thoroughly debrided during revision THA. A modular hemipelvic prosthesis was used for revision of the left hip. Four years later, the patient presented with right hip pain, where a mass appeared on the medial side of the proximal right thigh. A primary acetabular implant with augment was used for revision of the right hip. Laboratory evaluation of bloody fluid retrieved from surgery revealed elevated levels of inflammatory markers.ConclusionInflammatory responses to polyethylene wear debris can lead to severe bone resorption and aseptic loosening in the long‐term following THA. Therefore, in spite of revision THA, interrupting the cascade inflammatory might be the treatment principle for periprosthetic osteolysis.

ObjectiveAt present, the true sagittal alignment of the cervical spine is uncertain, resulting in no standard reference for subaxial cervical surgery. So, we aimed to explore the age difference of normal cervical sagittal alignment and to further investigate the mid‐and long‐term changes of sagittal alignment after subaxial cervical spine surgery.Materials and MethodsThis was a retrospective study and 1223 asymptomatic volunteers and 79 patients undergoing subaxial cervical spine surgery were retrospectively reviewed in total. Asymptomatic volunteers and patients were divided into six subgroups: 20–29, 30–39, 40–49, 50–59, 60–69 and ≥70 groups. The age difference and trend with age of cervical sagittal parameters of asymptomatic volunteers were assessed by cervical lateral radiography and analyzed by ANOVA test, and the regression equation of C2‐7 Cobb was established via multiple linear regression. Based on the C2‐7 Cobb regression equations of different ages, the theoretical value, deviation value, loss value of the C2‐7 Cobb, and JOA recovery rate of patients were calculated, and the correlation among the loss value, deviation value of the C2‐7 Cobb, and JOA recovery rate of the 79 patients was evaluated by Pearson correlation analysis.ResultsFor the asymptomatic volunteers, the C0‐2 Cobb decreased gradually with increasing age. The C2‐7 Cobb, C2‐7 SVA, T1S, NT, and TIA increased gradually with increasing age. The CBVA fluctuated with increasing age. T1S demonstrated a moderate correlation with C2‐7 Cobb (r = 0.60, p < 0.01); C0‐2 Cobb, C2‐7 SVA, CBVA, and TIA demonstrated a fair correlation with C2‐7 Cobb (r = −0.30, −0.33, 0.41, 0.40, p < 0.01); age demonstrated a poor correlation with C2‐7 Cobb (r = 0.19, p < 0.01). The regression equations of C2‐7 Cobb were established using C0‐2 Cobb, C2‐7 SVA, CBVA, and T1S. For the patients with subaxial cervical spine surgery, the loss of C2‐7 Cobb was moderately correlated with the deviation of C2‐7 Cobb (r = 0.33, p < 0.01).ConclusionThe age difference of cervical sagittal alignment was obvious, and the C2‐7 Cobb increased with age especially. The closer the postoperative C2‐7 Cobb was to the theoretical value of corresponding age, the smaller the loss of correction angle was, and the better the mid‐ and long‐term outcomes. The personalized sagittal reconstruction should be performed according to age difference for subaxial cervical spine surgery.

AbstractA 10‐year‐old female with a several‐year history of pityriasis lichenoides (PL) presented with a new, asymptomatic, large, and necrotic ulcer of her right upper arm. Skin biopsy was consistent with lymphomatoid papulosis (LyP) Type D, a recently recognized subtype of LyP that is distinguished histologically by marked epidermotropism and a perivascular infiltrate of medium‐sized pleomorphic lymphocytes with a cytotoxic phenotype (CD3+, CD8+). This is only the sixth reported case of LyP Type D in a child, and while the prognosis in children appears favorable, with no reports of progression to lymphoma to date, more experience in children with longer‐term follow‐up is needed. Our case highlights both the challenging clinical diagnosis, since in our patient the longstanding clinical presentation was indistinguishable from PL, as well as histopathologic diagnosis, which required expert opinion and consensus.

Published: July 2022

AbstractWe describe the rapid growth of a Reed nevus followed by its slow involution and present dermoscopic follow‐up images. The child was monitored for 10 years (from age 3 to 13 years) by digital dermoscopy. The Reed nevus completely lost its typical dermoscopic arrangement (starburst pattern) with involution and distinct changes in dermoscopic pattern.
Regulatory reforms, normative changes, and performance: Evidence from the electricity sector in Latin America
Authors: González Camilo Ignacio , Peci Alketa 
Published: July 2022

AbstractOver the past three decades the Latin American region has experienced various regulatory reforms, and distinctive normative changes have been introduced in the framework, instruments, or procedures adopted by independent regulatory agencies (IRAs). While there is evidence that the establishment of an IRA positively affects regulated sector performance, little is known about the effects of these additional legal dispositions when incorporated in primary or secondary legislation. However, normative changes may shape IRAs' actual regulatory activities and the signals they send to their stakeholders, potentially influencing sectoral performance. This research traces the evolution of several instruments and procedures legally adopted by IRAs located in Latin America and comprehensively assesses the influence of these normative changes on the performance dimensions of the electricity sector. We built indexes that describe the adoption of specific legal dispositions in the region. These indexes reveal that the evolution of the normative dispositions varies in terms of extent, context, and timing of adoption. In addition, the changes are not equally or even positively associated with specific performance dimensions. While economic regulatory instruments shape many performance dimensions, “soft” procedural dispositions also play an important role in perceptions of quality in the electricity sector.

AbstractInformation provision for social welfare via cheap technological media is now a widely available tool used by policymakers. Often, however, an ample supply of information does not translate into high consumption of information due to various frictions in demand, possibly stemming from the pecuniary and non‐pecuniary cost of engagement, along with institutional factors. We test this hypothesis in the Indian context using a unique data set comprising 2 million call records of enrolled users of ARMMAN, a Mumbai‐based nongovernmental organization that sends timely informational calls to mobile phones of less‐privileged pregnant women. The strict lockdown induced by COVID‐19 in India was an unexpected shock on engagement with m‐Health technology, in terms of both reductions in market wages and increased time availability at home. Using a difference‐in‐differences design on unique calls tracked at the user‐time level with fine‐grained time‐stamps on calls, we find that during the lockdown period, the call durations increased by 1.53 percentage points. However, technology engagement behavior exhibited demographic heterogeneity increasing relatively after the lockdown for women who had to borrow the phones vis‐à‐vis phone owners, for those enrolled in direct outreach programs vis‐à‐vis self‐registered women, and for those who belonged to the low‐income group vis‐à‐vis high‐income group. These findings are robust with coarsened exact matching and with a placebo test for a 2017–2018 sample. Our results have policy implications around demand‐side frictions for technology engagement in developing economies and maternal health.

AbstractBackgroundRosacea is a facial chronic inflammatory skin disease with almost 5.5% prevalence. Although there are various scales of rosacea, they are objective and discordant among different dermatologists. Noninvasive objective measurements such as VISIA system might play essential roles in the diagnosis and evaluation of rosacea. Here, we intended to reveal the effectiveness of VISIA system in rosacea.Materials and methodsA number of 563 participants diagnosed with facial rosacea were enrolled in study. They all received both full‐face image‐shoot by VISIA system with quantitative analysis software and physician's assessment via five different scales, including investigator global assessment (IGA), clinician erythema assessment (CEA), numerical score, the National Rosacea Society (NRS) grading system and telangiectasis.ResultsAbsolute score and percentile of red area had significant correlations with IGA and CEA, whereas red area had no significant correlation with numerical score, NRS and telangiectasis. Red area in erythematotelangiectatic rosacea patients demonstrated the highest correlation with IGA and CEA, especially in those aged between 51 and 60. Besides red area, pigmentation parameters in VISIA system (brown spot) also showed significant correlation with IGA and CEA.ConclusionVISIA system might be an effective measurement in the assessment of rosacea severity.
Effect of cover crops residue on weed control and yield in conservation tillage tomato (Lycopersicon esculentum Mill.) production
Authors: Samedani Batoul , Meighani Fariba 
Published: July 2022

AbstractIt has been proved that cover crops combined with minimal or no till in tomato production reduce weed pressure and simultaneously slow down soil erosion, conserve soil organic carbon, and improve soil fertility. Therefore, a study was conducted to evaluate the interaction effects of cover crops including legumes, (Vicia villosa Roth and Vicia sativa L.), and legumes mixed with grasses (Secale cereale L. and X Triticosecale Wittmack), and cover crop biomass management (incorporation of residues into soil, strip tillage and no tillage) on weed control, tomato yield, nitrogen level of tomato leaf and soil, and soil organic carbon for 2 years. Generally, cover crops reduced weed dry weight in all tillage systems, and increased tomato leaf N level compared to that of conventional methods, but soil N and organic carbon contents were not affected throughout the experiments. In 2017, the highest tomato yield (40.5 and 41.1 t ha−1) was recorded in legumes and mixed legumes‐grasses treatments with no‐till management, respectively. However, in 2018, the tomato yield decreased about 41% in the latter treatment. Totally, legume treatments in incorporation residue into soil and no‐till systems with 61.3 and 61.2 t ha−1, and mixed legumes‐grasses treatments in strip‐till system with 62.2 t ha−1, respectively, had the highest tomato yield compared to that of other treatments. It seemed legumes‐grasses treatment in the strip‐till was generally more advantageous over the no‐till. Based on results, to make possible no‐till in vegetable systems, cover crops should provide an appropriate seedbed for tomato roots in the soil.
Performance improvement and decolourization in the high‐solid thermophilic anaerobic digestion of thermally pretreated sewage sludge
Authors: Takashima Masanobu , Yaguchi Junichi 
Published: July 2022

AbstractThis laboratory‐scale study attempted performance improvement and decolourization in the high‐solid thermophilic anaerobic digestion of thermally pretreated sewage sludge, as it tends to be disturbed by ammonia inhibition and colour generation. Sewage sludge was adjusted to 7%–8% total solids (TS), and pretreated at 150°C for 1 h. The digesters were operated at 55°C and 20 days hydraulic retention time. An addition of powdered activated carbon (approximately 2% of the feed TS) significantly contributed to the removal of propionate and reduced the colour in digested sludge by about 27%. Microbial analysis detected less abundance of bacterial Synergistia and archaeal Methanosarcina and implied more hydrogenotrophic methanogenesis with the activated carbon addition. Conditioning with ferric chloride for dewatering digested sludge mitigated the colour of dewatered liquor by about 67%. Therefore, these methods were demonstrated to be effective and partly overcome the above‐mentioned problems.

Purpose: This study examined the associations among common assessments for measuring strength and power in the lower body of high-performing athletes, including both cross-sectional and longitudinal data. Methods: A total of 100 participants, including both male (n = 83) and female (n = 17) athletes (21 [4] y, 182 [9] cm, 78 [12] kg), were recruited for the study using a multicenter approach. The participants underwent physical testing 4 times. The first 2 sessions (1 and 2) were separated by ∼1 week, followed by a period of 2 to 6 months, whereas the last 2 sessions (3 and 4) were also separated by ∼1 week. The test protocol consisted of squat jumps, countermovement jumps, jump and reach, 30-m sprint, 1-repetition-maximum squat, sprint cycling, and a leg-press test. Results: There were generally acceptable correlations among all performance measures. Variables from the countermovement jumps and leg-press power correlated strongly with all performance assessments (r = .52–.79), while variables from sprint running and squat-jump power displayed more incoherent correlations (r = .21–.82). For changes over time, the correlations were mostly strong, albeit systematically weaker than for cross-sectional measures. Conclusions: The associations observed among the performance assessments seem to be consistent for both cross-sectional data and longitudinal change scores. The weaker correlations for change scores are most likely mainly caused by lower between-subjects variations in the change scores than for the cross-sectional data. The present study provides novel information, helping researchers and practitioners to better interpret the relationships across common performance assessment methods.

Published: July 2022

Purpose: The authors investigated whether far-infrared radiation (FIR) lamp therapy would reduce muscle damage and enhance recovery from multiple soccer-match-related running activities. Methods: Twenty-four elite female soccer players (20–24 y) were assigned into a FIR or a sham treatment group (n = 12/group). They performed a daily 90-minute Loughborough Intermittent Shuttle Test (LIST) for 6 consecutive days. Maximal voluntary contraction torque of the knee extensors (KEs) and flexors, muscle soreness, plasma creatine kinase activity, countermovement jump, and several other performance measures (eg, 30-m dash, Yo-Yo Intermittent Recovery Test Level 1) were taken before the first LIST, 1 hour after each LIST, and 24, 48, 72, 96, and 120 hours after the last LIST. All participants received a 30-minute FIR or sham treatment on KEs and knee flexors, respectively, at 2 hour after each LIST and 25, 49, 73, and 97 hours after the last LIST. Results: All measures changed significantly (P < .05) at 1 hour after the first LIST without difference (P > .05) between groups. Maximal voluntary contraction torque (eg, the largest decrease of KE for FIR: 13% [4%], sham: 25% [5%]), countermovement jump height (4% [3%] vs 14% [4%]), and other performance measures (eg, Yo-Yo Intermittent Recovery Test: 11% [5%] vs 26% [5%]) decreased less, and peak muscle soreness (eg, KE: 26 [9] vs 51 [18] mm) and plasma creatine kinase activity (172 [32] vs 1289 [610] IU/L) were smaller for the FIR than for the sham group (P < .05), and they returned to the baseline earlier (P < .05) for the FIR group. Conclusions: These results suggest that the FIR therapy provided potent effects on reducing accumulated muscle damage and enhancing recovery.

Published: July 2022

The present study aimed to examine the impact of the level of physical activity on prefrontal cortex activation in older adults during single- and dual-task walking. Thirty physically inactive and 36 active older adults (60–85 years old) performed six 2-min tasks on a treadmill: two static cognitive tasks, two single-task walking tests, and two dual-task walking tests. Hemodynamics at the level of the prefrontal cortex were measured continuously using functional near-infrared spectroscopy to evaluate cortical activation. The perceived difficulty of the task, cognitive performance, and gait parameters were also measured. During the walking tasks, the level of prefrontal cortex activation, the perceived difficulty of the task, cognitive performance, and motor parameters were not significantly different between active and inactive older adults. This unchanged activation with physical activity was likely the consequence of a similar motor and cognitive load and cardiorespiratory fitness in both active and inactive older adults.

Abstract
In the development of promising ULIS scaling technologies, one of the key roles is played by porous dielectrics with a low permittivity used to isolate interconnects in a metallization system. Condensation of gaseous products in the pores of such films makes it possible to solve the most important problem that prevents the integration of such films, to carry out low-damage plasma etching. However, methods for studying porosity are also based on the study of the adsorption isotherm during condensation in film pores. Therefore, the study of adsorption in pores is one of the most important practical problems arising in the creation of dielectrics with a low permittivity and the study of low-damaging methods for their structuring. The method of ellipsometric porosimetry is an easy-to-implement and accurate approach for obtaining an adsorption isotherm; however, its further analysis and determination of the pore size distribution are reduced to solving an integral equation and is an ill-posed problem. In this paper, we propose to apply Tikhonov’s regularization method to solve it. The method is verified on model data and used to study a low-k dielectric sample with an initial thickness of 202 nm and a permittivity of 2.3 based on organosilicate glass.
