A Class-AB LDO regulator with high stability suitable for multiple input reference voltages
Authors: Ge Zhongyuan , Dong Zizheng , Li Yingtao 
Published: August 2024

Abstract
A Class-AB LDO capable of sinking/sourcing current from/to the load is presented. Unlike conventional LDO structures, the input reference voltage of this circuit is adjustable and has a wide adjustment range. The circuit has been demonstrated in a 0.35 um BCD process at a 3.3 V supply voltage. Its low-frequency sourcing 10 mA current, sinking 10 mA current and no-load PSRR are -80.3 dB, -106.1 dB, and -83.4 dB, respectively. The voltage undershoot is 69 mV when the output changes from sinking 10 mA to sourcing 10 mA in 10 us, and the overshoot is 64 mV for the opposite process. The minimum phase margin is 50 degrees at 0.1-10 mA load current. The area of the entire LDO circuit is 0.28 mm2, including the protection circuit.
Metamerism problem in the colour recipe calculation
Authors: Ludaš Anja , Ira Glogar Martinia , Ercegović Ražić Sanja 
Published: August 2024

Abstract
The analysis presented in this paper was carried out in the context of two main objectives. One was the study of the phenomenon of metamerism, and the other was the investigation of the possibility of applying new acid dyes in relation to the already known ones, from the aspect of durability, and ecological and economic sustainability. The analysis was carried out on samples dyed under industrial conditions in the Jadran d.d. sock factory. The aim was to show the phenomenon of metamerism as one of the key parameters of quality control in dyeing, which, if present, prevents the conversion of production to new dyes that would allow faster and cheaper production with a higher degree of dye exhaustion, which certainly has an impact on economic and environmental sustainability. The analysis of the metamerism was performed spectrophotometrically and the results are shown in a form of the reflectance curves, the numeric evaluation of colour parameters (L*, C*, h) and the positioning of the colours in the a*/b* colour space. The analysis and comparison of the colorations obtained with two types of dyes (new generic and known) did not show a great difference in the occurrence of the phenomenon of metamerism. This speaks in favour of the further development of new dyes that, whose improved properties, would contribute to an improvement in the context of sustainability, although this part is still within the scope of the research hypothesis that continues and whose results will be published in further publications.
Full SMAS: Endoscopy-Assisted Full Facial Rejuvenation
Authors: Casagrande Carlos , Facin Emilio , Saltz Renato 
Published: August 2024

Abstract

Background
Every region of the face may bear the signs of aging. Treating isolated areas without adequate anatomical knowledge can lead to incomplete or artificial-looking results and decrease patient satisfaction. The authors’ “Full SMAS” technique for complete rejuvenation addresses the anatomical continuity of the superficial musculoaponeurotic system (SMAS)-platysma to the deep-plane suspension of the face.

Objectives
The aim of this study was to evaluate the contribution of endoscopic techniques to traditional facelift and neck lift procedures. Procedures treating from the frontal and temporal regions of the superior part of the face to its mid and lower parts, including the cervical region, were evaluated.

Methods
Treatment of the 3 sub-SMAS layers of the face was performed using endoscopy for repositioning the frontal region and midface. This procedure involved frontal and zygomatic-masseter ligament release, open treatment of the lower subplatysmal section, and the complete release of the retaining ligaments of the face and approach to the jowl.

Results
One hundred sixty-one patients underwent the Full SMAS technique, leading to long-lasting results, low complication rates, and high patient satisfaction.

Conclusions
The Full SMAS is a systematic technique that provides complete facial rejuvenation by combining an endoscopic approach for the temporal and midface regions with traditional open approaches for the lower face and neck. Treating the temporal and midface regions by minimally invasive techniques (endoscopy) reduces the possibility of permanent nerve injuries, provides smaller scars, and creates natural, long-lasting results.

The relationship between neutral genetic diversity and performance in wild arthropod populations
Authors: Ho Tammy Ai Tian , Downing Philip A , Schou Mads F , Bechsgaard Jesper , Thomsen Philip Francis , Jorgensen Tove H , Bilde Trine 
Published: August 2024

Abstract
Larger effective populations (Ne) are characterized by higher genetic diversity, which is expected to predict population performance (average individual performance that influences fitness). Empirical studies of the relationship between neutral diversity and performance mostly represent species with small Ne, while there is limited data from the species-rich and ecologically important arthropods that are assumed to have large Ne but are threatened by massive declines. We performed a systematic literature search and used meta-analytical models to test the prediction of a positive association between neutral genetic diversity and performance in wild arthropods. From 14 relevant studies of 286 populations, we detected a weak (r = 0.15) but nonsignificant positive association both in the full data set (121 effect sizes) and a reduced data set accounting for dependency (14 effect sizes). Theory predicts that traits closely associated with fitness show a relatively stronger correlation with neutral diversity; this relationship was upheld for longevity and marginally for reproduction. Our analyses point to major knowledge gaps in our understanding of relationships between neutral diversity and performance. Future studies using genome-wide data sets across populations could guide more powerful designs to evaluate relationships between adaptive, deleterious and neutral diversity and performance.
Case report: thigh hidradenoma masquerading as lipoma
Authors: Alhaqbani Abdullah , Alawfi Homoud , Alahmadatea Firas , Almalki Sami 
Published: August 2024

Abstract
Hidradenomas are benign adnexal neoplasms, which were recently been subdivided into two groups: eccrine differentiation (poroid hidradenomas) or apocrine differentiation (clear cell hidradenomas) with the latter being rarer. These types of tumors have been associated with recurrence and malignant transformation; however, recurrence and malignancy are considered very rare. We present a case report of a 35-year-old male who presented with two lumps, clinically representing simple lipomas but one of them turned to be a hidradenoma. A 35-year-old gentleman not known to have any medical illnesses and surgically free, presented to our general surgery clinic complaining of two slow-growing (over 3 years) painless lumps, one in the right upper thigh and the other one in the left shoulder. The patient denied any previous history of trauma or infection nor any history of discharge or overlying skin changes, and there were no clinical features that might suggest the presence of malignancy. Upon examination, both lumps were firm, freely mobile, non-tender, intact overlying skin, with no skin changes, and no regional lymphadenopathy. Prior to excision, our preliminary impression was lipoma for both masses. Surgical excision was carried out with clear margins; each mass was labeled separately, and specimens were sent for histopathology. Histopathological diagnosis of the left shoulder mass was consistent with lipoma; however, the right upper thigh mass turned to be a hidradenoma. Hidradenomas are uncommon benign neoplasms with varied types. Recurrence and transformation into malignancy have been reported in some cases. Complete surgical excision with negative margins and further follow-up with the patient are crucial to prevent such consequences. Clinical diagnosis can be difficult; however, the management is the same with surgical removal as it will give us the definitive diagnosis with the pathology report.
Optimizing Aesthetic Outcomes after Retroglandular Breast Implant Explantation
Authors: Maciel Patrícia J. 
Published: August 2024

Summary:
The safety of silicone breast implants has been questioned due to concerns such as the risk of associated lymphoma, as well as rheumatological and systemic symptoms. This has resulted in an increased demand for explantation, posing the challenge of addressing stigmas related to implant removal. There is a dearth of literature on techniques for restoring breast contour postexplantation. After implant removal, the original breast anatomy is altered, and depressed areas may manifest in random locations. To reposition the breast tissue displaced by the implant, we enlarge the retroglandular pocket and subsequently use sutures for centripetal traction, relocating the tissue back to the footprint area but now in an improved position, delineating the breast contour. This maneuver enables us to restore the breast contour to an anatomical condition akin to preimplantation; diminish the final explantation defect, creating a more suitable pocket for delicate mastopexy flaps; recruit breast tissue, allowing internal sutures to conceal tissue irregularities; and redesign the breast contour area on the chest to achieve better symmetry.

Authors: Akerman Michelle , Sneag Darryl B. , Gfrerer Lisa , Endo Yoshimi , Valenti Alyssa B. , Clements Isaac P. , Tan Ek T. 
Published: August 2024

Background:
Nerve Tape is a novel nerve repair device containing nitinol microhooks that provide sutureless attachment for nerve coaptation. This study evaluated visualization of Nerve Tape on magnetic resonance imaging (MRI) and ultrasound, with the objective of exploring its potential as an imaging marker for localizing nerve repair sites.

Methods:
Phantom imaging experiments were first conducted to assess the visibility of Nerve Tape on MRI and ultrasound. A cadaveric limb investigation was then performed to further characterize the magnetic susceptibility patterns of Nerve Tape and to confirm its localization at the repair site.

Results:
Phantom imaging experiments demonstrated clear visualization of Nerve Tape on both MRI and ultrasound, with Nerve Tape microhooks appearing as signal voids on MRI and hyperechoic foci on ultrasound. Subsequent cadaveric limb investigation further characterized Nerve Tape’s magnetic susceptibility patterns and confirmed localization of the device at the repair site. The physical dimensions of Nerve Tape and locations observed on both MRI and ultrasound matched design and measurements made during surgery. Measurement discrepancies could be attributed to magnetic susceptibility artifacts in MRI, and to comet tail and shadowing effects in ultrasound.

Conclusions:
Repairs performed with Nerve Tape can be reliably localized for imaging, potentially facilitating assessment of repair site integrity and further advancement toward image-based monitoring of nerve regeneration. Further research, including in vivo human studies, is warranted to confirm these preliminary findings.

Authors: Pu Chan Yeu , Ospina-Delgado Daniel , Kheir Fayez , Avendano Camilo A. , Parikh Mihir , Beattie Jason , Swenson Kai E. , Wilson Jennifer , Gangadharan Sidharta P. , Majid Adnan 
Published: August 2024

Background:
Short-term airway stent placement (stent evaluation) has been employed to evaluate whether patients with excessive central airway collapse (ECAC) will benefit from tracheobronchoplasty. Although retrospective studies have explored the impact of stent placement on ECAC, prospective randomized controlled trials are absent.

Methods:
This was a randomized open-label trial comparing patients receiving airway stent placement and standard medical treatment (intervention group) versus standard medical treatment alone (control group) for ECAC. At baseline, patients’ respiratory symptoms, self-reported measures, and functional capabilities were assessed. Follow-up evaluations occurred 7 to 14 days postintervention, with an option for the control group to crossover to stent placement. Follow-up evaluations were repeated in the crossover patients.

Results:
The study enrolled 17 patients in the control group [medical management (MM)] and 14 patients in the intervention group. At follow-up, 15 patients in the MM crossed over to the stent group, resulting in a total of 29 patients in the combined stent group (CSG). Subjectively (shortness of breath and cough), 45% of the CSG exhibited improvement with the intervention compared with just 12% in the MM. The modified St. George Respiratory Questionnaire score in the CSG improved significantly from 61.2 at baseline to 52.5 after stent placement (-8.7, P = 0.04). With intervention, the 6-minute walk test in CSG improved significantly from 364 meters to 398 meters (34 m, P < 0.01). The MM did not show a significant change in the St. George Respiratory Questionnaire score or 6-minute walk test distance.

Conclusion:
Short-term airway stent placement in patients with ECAC significantly improves respiratory symptoms, quality of life, and exercise capacity.
Comparison of adalimumab with methotrexate for psoriasis: A meta-analysis of randomized controlled studies
Authors: Yang Xiaolin , Liu Yan 
Published: August 2024

Introduction:
The efficacy of adalimumab versus methotrexate for psoriasis remained controversial. We conducted this systematic review and meta-analysis to explore the influence of adalimumab versus methotrexate on treatment efficacy for psoriasis patients.

Methods:
We have searched PubMed, EMbase, Web of Science, EBSCO, and Cochrane Library databases through August 2023 for randomized controlled trials (RCTs) assessing the efficacy of adalimumab versus methotrexate for psoriasis. This meta-analysis was performed using the random-effect or fixed-effect model based on the heterogeneity.

Results:
Four RCTs and 733 patients with psoriasis were included in this meta-analysis. Overall, compared with methotrexate treatment, adalimumab treatment was associated with improved Psoriasis Area and Severity Index 75 (PASI 75, odd ratio [OR] = 4.50; 95% confidence interval [CI] = 2.81–7.22; P < .00001), physician global assessment (PGA) 0/1 response (OR = 4.86; 95% CI = 3.02–7.82; P < .00001), PASI 100 (OR = 3.01; 95% CI = 1.33–6.80; P = .008) and decreased Dermatology Life Quality Index (DLQI, standard mean difference [SMD] = −0.60; 95% CI = −0.84 to −0.36; P < .00001), but exhibited no impact on PASI 90 (OR = 3.30; 95% CI = 0.77–14.20; P = .11), adverse events (OR = 1.23; 95% CI = 0.26–5.87; P = .79) or serious adverse events (OR = 2.59; 95% CI = 0.49–13.79; P = .26).

Conclusions:
Adalimumab was superior to methotrexate for the treatment of psoriasis.
A rare association of pheochromocytoma, paraganglioma, and pituitary adenoma (3PA): A case report and literature review
Authors: Rahmati Rahem , Meftah Elahe , Hamidi Hamed , Esfahanian Fatemeh 
Published: August 2024

Rationale:
3P association (3PA) is a rare condition with co-occurrence of pituitary adenoma and pheochromocytoma/paraganglioma. There have been less than a hundred documented cases of 3PA, which can be sporadic or related to genetic mutations. The present case report describes the first Iranian patient with 3PA and a 90th case of 3PA in the available literature.

Patient concerns and interventions:
A 36-year-old Caucasian male was admitted with headache and sudden increase in blood pressure. An abdominal CT scan revealed a retroperitoneal mass posterior to the inferior vena cava, later removed and diagnosed as a pheochromocytoma. Four years later, he noticed occasional mild headaches and a painless mass on the right side of his neck. The ultrasonography evaluations suggested a carotid body tumor, which was surgically removed. About a month after his second surgery, the severity of the patient’s headaches worsened, and he developed right homonymous hemianopia. A brain MRI showed a mass in favor of macroadenoma, craniopharyngioma, or meningioma, and elevated prolactin level led to the diagnosis of macroprolactinoma.

Diagnoses:
Based on the provided history, this patient was diagnosed with 3PA, and a genetic study identified a positive succinate-dehydrogenase-complex subunit b mutation, possibly linked to his family history of carotid body tumor.

Outcomes:
He has remained symptom-free during his visits every 3 months.

Lessons:
The number of cases diagnosed with 3PA worldwide is increasing. Using clinical and genetic assessments, we can timely diagnose and adequately monitor individuals with or at risk of 3PA.

Patient concerns:
Cough with light-yellow phlegm for 2 weeks.

Diagnoses:
The final diagnosis was bacterial pneumonia.

Interventions:
The patient was treated with ceftazidime (2 g, every 12 h) for 1 week.

Outcomes:
The patient’s lung infection improved and he was discharged.

Lessons:
This case highlights a rare occurrence of lung infection caused by Shewanella algae in elderly Tibetan men residing in non-marine environments.
Impact of the COVID-19 pandemic on risk of sarcopenia: From lockdown and infection perspectives: A systematic review and meta-analysis
Authors: Wang Xiang , Guo Qiaofeng , Huang Kai , Ma Gouping , Zhai Lifeng , Lin Bingyuan , Ren Haiyong , Yang Ze 
Published: August 2024

Background:
During the new coronavirus disease 2019 (COVID-19) pandemic, there are numerous symptoms in the skeletal muscular system, such as decreased skeletal muscle mass, strength, and muscle function, which are the main manifestations of sarcopenia. To investigate the impact of the COVID-19 pandemic on sarcopenia from the perspectives of COVID-19 pandemic lockdown and COVID-19 infection, we conducted this study.

Methods:
We searched for literature related to COVID-19 and sarcopenia published in PubMed, Embase, Cochrane Library, and Web of Science. Two researchers independently searched and screened the articles, extracted data, and assessed the quality of the final included literature. RevMan 5.4 was used for meta-analysis.

Results:
A total of 8 articles with a total of 1145 patients were included. There was a significant difference in SARC-F scores (MD = 0.67, 95%CI = [0.41, 0.93], Z = 5.00, P < .00001), handgrip (MD = ‐1.57, 95%CI = [‐2.41, ‐0.73], Z = 3.66, P = .0002), body weight (MD = ‐1.87, 95%CI = [‐3.69, ‐0.05], Z = 2.01, P = .04), and skeletal muscle mass index (MD = ‐0.28, 95%CI = [‐0.54, ‐0.02], Z = 2.13, P = .03) between the time before the COVID-19 pandemic and during the COVID-19 pandemic. However, the results showed that there was no significant difference in muscle mass between the 2 groups (MD = ‐1.72, 95%CI = [‐4.39, 0.94], Z = 1.27, P = .21).

Conclusion:
The COVID-19 pandemic has had an impact on sarcopenia. Both infection with COVID-19 and lockdown during the COVID-19 pandemic increase the risk of sarcopenia. Research should pay more attention to this disease during the COVID-19 pandemic and adopt effective interventions to minimize adverse outcomes.
A giant solitary fibrous tumor of the abdominal pelvic cavity: A case report and literature review
Authors: Li Cao , Yang Jianyang , Chen Hongli , Yang Lie 
Published: August 2024

Rationale:
Solitary fibrous tumor (SFT) is a rare mesenchymal tumor, especially the giant one from the abdominal pelvic cavity. We report on a rare case of a giant SFT of the abdominal pelvic cavity to review the existing literature in detail to improve the diagnosis and treatment of SFT.

Patient concerns:
The patient is a 52-year-old female who presented with 2 weeks of abdominal distension. Abdominal magnetic resonance imaging showed a giant mass (>20 cm) in the abdominal pelvic cavity, considered a mesenchymal tumor. She denies a history of tumor disease.

Diagnoses:
A whole abdomen bulge and a mass of about 18 cm × 10 cm on the right side and middle side were found in the physical examination after admission. Abdominal enhanced computed tomography revealed a giant cystic-solid mass located on the middle and right side of the abdominal pelvic cavity, measuring approximately 20.4 cm × 11.7 cm, with multiple cystic changes and necrosis and compression of adjacent organs and tissues, and marked inhomogeneous enhancement.

Interventions:
The patient underwent an open abdominal pelvic cavity giant tumor operation to achieve a radical resection, and did not undergo chemotherapy or radiotherapy.

Outcomes:
The patient underwent open complete resection of a giant abdominal pelvic tumor with no complications and was diagnosed as SFT according to the pathology, immunohistochemistry showed that the tumor tested positive for CD34(+), STAT-6(+), and Ki-67 (10%). Abdominal computed tomography scans were performed 6 months after resection, and no signs of recurrence or metastasis were found.

Lessons:
The clinical symptoms and imaging features of giant abdominal pelvic cavity SFT are not typical. Preoperative diagnosis is difficult and has the potential for malignancy. Based on the results of the current study, there is no standard treatment strategy around the world and the therapeutic effect of radiation therapy and chemotherapy is relatively limited. Thus, complete surgical resection and close clinical follow-up are advocated.
Critical illness-associated cerebral microbleeds involving the corpus callosum following cardiac arrest: A case report
Authors: Srichawla Bahadar S. , Fang Ton , Kipkorir Vincent , Lalla Rakhee 
Published: August 2024

Rationale:
Critical illness-associated cerebral microbleeds (CI-aCMBs) are emerging as significant radiographic findings in patients with hypoxic ischemic injuries. Their occurrence, particularly in the corpus callosum, warrants a closer examination due to the potential implications for neurological outcomes in critically ill patients. We aim to describe a rare case of CI-aCMBs within the corpus callosum following cardiac arrest with the goal of bolstering the scientific literature on this topic.

Patient concerns:
A 34-year-old man with a history of polysubstance abuse was found unconscious and experienced a pulseless electrical activity (PEA) cardiac arrest after a suspected drug overdose. Post-resuscitation, the patient exhibited severe respiratory distress, acute kidney injury, and profound neurological deficits.

Diagnoses:
Initial magnetic resonance imaging scans post-cardiac arrest showed no acute brain abnormalities. However, subsequent imaging revealed extensive cerebral microbleeds predominantly in the corpus callosum, diagnosed as CI-aCMBs. These findings were made in the absence of high signal intensity on T2-weighted images, suggesting a unique pathophysiological profile of microhemorrhages.

Interventions:
The patient underwent targeted temperature management (TTM) and supportive care in the intensive care unit after cardiac arrest.

Outcomes:
He was subsequently extubated and had significant recovery without any neurological deficits.

Lessons:
CI-aCMBs is a rare radiographic finding after cardiac arrest. These lesions may be confined to the corpus callosum and the long-term clinical and radiographic sequelae are still largely unknown.
