Iagnosis and treatment of myelitis after lumbar reoperation: A case report
Authors: Li Dongru , Chen Xiao , Zhang Zifang , Liang Xiao , Gao Xu , Tian Zhikang , Meng Chunyang 
Published: February 2024

Rationale:
At present, acute myelitis (AM) is a great challenge to diagnosis and treatment because of its complicated etiology, critical condition, and poor prognosis, and it is easy to leave different degrees of limb motor dysfunction. The report of this case is helpful to improve the understanding of AM after lumbar surgery, reduce misdiagnosis and provide reference for clinical treatment.

Patient’s concern:
This study reported a case of AM after lumbar reoperation. Before the patient was diagnosed as AM, we gave high-dose hormone anti-inflammatory and detumescence symptomatic treatment according to empirical treatment, and the effect was ideal and rehabilitation treatment was actively carried out at the right time. After 10 months of follow-up, the patient recovered well.

Diagnosis:
Because lumbar surgery is a contraindication of lumbar puncture, the patient’s diagnosis was confirmed by thoracic magnetic resonance imaging. Magnetic resonance imaging of thoracic vertebra on the 17th day after lumbar operation showed that small round T1W1 signal, slightly higher T2W1 signal and T2-fat suppression imaging equal signal were seen in the horizontal spinal cord of thoracic vertebra 10.

Intervention:
According to the empirical treatment, patients have been given high-dose hormone therapy after operation, and comprehensive treatment such as comprehensive training of paraplegic limbs, joint loosening training, electric massage and other rehabilitation training will be carried out when the general condition of patients improves.

Outcomes:
After 10 months of follow-up, there were no major sequelae such as limb paralysis.

Conclusion:
Due to the rarity of AM in clinical work, it is easy for doctors to ignore the disease and miss the best treatment stage, which will lead to serious sequelae.
Prostatic abscess due to carbapenem-resistant K. pneumonia: A case report
Authors: Zhou Wen-Qiang , Chen Zhi , Cai Xue-Ju 
Published: February 2024

Rationale:
Due to the widespread use of broad-spectrum antibiotics, the morbidity of prostate abscesses (PA) has declined dramatically. However, under special circumstances, such as invasive procedures and immunosuppressive conditions, some patients are more likely to develop this disease. Here, we present the case of a 21-year-old man, diagnosed with PA, with a history of chronic steroid use and a long-term indwelling urinary catheter. The pathogen was confirmed as carbapenem-resistant Klebsiella pneumoniae, a rare bacterium. This case indicates that immunodeficiency and invasive catheter use may be risk factors for PA and opportunistic bacterial infections.

Patient concerns:
A 21-year-old young man presented with sudden onset of high fever (39.7°C). The patient had a history of long-term use of steroids and long-term indwelling urinary catheter. Digital rectal examination revealed obvious swelling and tenderness of the prostate. Subsequent pelvic magnetic resonance imaging showed a high signal lesion measuring 2.1 × 2.9 × 2.8 cm with T1 enhancement and T2 enhancement.

Diagnoses:
On the 8th day of hospitalization, the patient underwent a PA drainage procedure and a pus culture was conducted. Subsequent pus and urine cultures showed the presence of Klebsiella pneumoniae, which exhibited resistance to all injectable carbapenems, cephalosporins, aminoglycosides, piperacillin-tazobactam, and quinolone drugs.

Interventions:
On the 8th day of hospitalization, the patient underwent PA drainage surgery under general anesthesia to drain the abscess and relieve obstruction. After the surgery, the patient received a 2-week treatment of doxycycline.

Outcomes:
Finally, the patient was discharged after recovery and did not experience recurrence during the 6-month follow-up period.

Lessons:
PA is not commonly found, but some patients are more susceptible to this disease under certain host conditions. Immunodeficiency and invasive catheter use may be risk factors for PA and opportunistic bacterial infections. The use of omadacycline for the treatment of carbapenem-resistant Klebsiella pneumoniae infections appears to be effective.
Re-evaluation for systematic reviews of traditional Chinese medicine in the treatment of chronic bronchitis
Authors: Deng Yasheng , Xi Lanhua , Han Siyin , Liang Tianwei , Huang Hui , Fan Yanping , Zheng Yiqing , Lin Jiang 
Published: February 2024

Background:
Chronic bronchitis (CB) is a common clinical chronic respiratory disease, which has a high incidence in the middle aged and elderly population. With the development of the disease, the number of acute attacks becomes more and more frequent, which leads to the continuous decrease of lung function. If not treated in time, it will lead to a variety of complications and seriously affect the quality of life of patients. Traditional Chinese medicine (TCM) or TCM combined with western medicine is highly effective in the treatment of CB disease. In recent years, there are many systematic reviews on the use of TCM therapy in the treatment of CB, and the efficacy and safety of TCM in the treatment of CB diseases are evaluated. The aim of this study was to re-evaluate the Meta analysis/Systematic reviews (MAs/SRs) of TCM for the treatment of CB, aiming to provide a clinical basis for the treatment of CB by TCM.

Methods:
Retrieval among Chinese and English databases such as China National Knowledge Infrastructure, Wanfang database, China Scientific Journals Database, SinoMed, PubMed, Web of Science, The Cochrane Library and EMbase, etc. were conducted within the duration from database establish Tion date to March 2023.The included research was independently conducted by 2 researchers for literature screening, data extraction, and quality evaluation. The AMSTAR 2 scale was used to evaluate the quality of the report, the PRISMA 2020 statement evaluated the quality of the report, the ROBIS tool evaluated the risk of bias, and the GRADE quality evaluation tool evaluated the quality of the evidence.

Results:
Fifteen MAs/SRs were included, for a total of 224 studies involving 20,710 patients with CB. The 15 studies included in AMSTAR 2 are of very low quality. The ROBIS evaluation results showed that 8 MAs/SRs were considered to have high risk and 7 with low risk. The PRISMA 2020 report quality showed evaluation results of the included studies scores between 24 and 30, among them 13 with high quality and 2 with low quality. The GRADE system results showed that, within 70 outcome indicators, only 14 of them have moderate quality for evidence, with 31 for low quality, 25 for very low quality, and none for high quality.

Conclusion:
The MAs/SRs methodological quality of using TCM for treatment CB is generally poor, the quality of reports as well as evidence are generally low, and the risk of bias is high, therefore we should treat these results with caution.
Meta-analysis of stereotactic hematoma removal and craniotomy hematoma removal in the treatment of hypertensive intracerebral hemorrhage in the elderly
Authors: Tang Chao , Zhang Min , Li Wei 
Published: February 2024

Background:
A large number of clinical studies suggested that surgery might be a better choice than conservative treatment for treating hypertensive intracerebral hemorrhage in the middle-aged and elderly. Stereotactic puncture can reduce the mass effect caused by hematoma, reduce the intervention of body homeostasis, reduce brain tissue damage, and improve the prognosis of patients with cerebral hemorrhage. This meta-analysis aims to evaluate the efficacy of stereotactic puncture and craniotomy in elderly patients with hypertensive intracerebral hemorrhage.

Methods:
A search strategy was designed to search in databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials, CNKI, Wanfang database and relevant references. Literature on the efficacy and safety of different surgical methods for hypertensive cerebral hemorrhage in the middle-aged and elderly were retrieved. The search time was until August 17, 2022. Keywords included “hypertensive intracerebral hemorrhage,” “stereotactic hematoma removal,” “craniotomy.” After the literature search, 2 researchers independently conducted literature screening, quality evaluation of included trials and data extraction. RevMan5.4 software was used to perform a Meta-analysis on the operation time, hospital stay, postoperative Glasgow Coma Scale (GCS) score, postoperative daily activity ability, postoperative complications and neurological prognosis scores included in the included studies.

Results:
A total of 1988 samples were included in 9 studies. 1022 patients underwent stereotactic hematoma removal, and 968 patients underwent craniotomy hematoma removal. The orientation group had more advantages in the length of hospital stay, postoperative disability, pulmonary infection, intracranial infection and digestive tract ulcer, and the difference was statistically significant (P < .05). In addition, the length of stay (I²= 83%) of the included articles had good homogeneity (I²< 50%), and there was no significant difference between the 2 groups in operation time, postoperative GCS score, postoperative daily activity ability, and neurological prognosis score (P > .05).

Conclusion:
The meta-analysis indicate that compared to craniotomy for hematoma removal, stereotactic hematoma removal can reduce the postoperative disability rate, intracranial infection rate, lung infection rate, and digestive tract ulcer rate in middle-aged and elderly patients with hypertensive intracerebral hemorrhage.
Utility of iPhone-Based Pupillometry in Comparing Pupillary Dynamics Between Sport Concussed Subjects With Photosensitivity and Healthy Controls
Authors: Dutta Pritam 
Published: February 2024

Background:
To compare the pupillary dynamics using an iPhone-based pupillometry technique in subjects with sports concussion with photosensitivity and aged-matched controls.

Methods:
Fifty subjects with sports concussion were compared with 50 aged-matched healthy controls. Athletes with persistent concussive symptoms for 1 year or more after the initial injury were included. All the subjects underwent a Post-Concussion Symptom Scale (PCSS) administration followed by pupillary dynamics measurement using an iPhone-based application (Reflex-Pro PLR analyzer).

Results:
The mean age was 27 ± 4 years in the concussed group and 26 ± 5 years in the control group. In subjects with concussion, there was a significant decrease in the mean of the following parameters: average constriction speed (1.10 ± 0.15 vs 1.78 ± 0.12 mm/s; P < 0.001), maximum constriction speed (2.05 ± 0.26 vs 3.84 ± 0.28 mm/s; P < 0.001), average diameter (3.64 ± 0.12 vs 0.36 ± 0.05 mm; P < 0.001), maximum diameter (4.75 ± 0.17 vs 5.23 ± 0.16 mm; P < 0.001), and minimum diameter (2.75 ± 0.17 vs 3.64 ± 0.11 mm; P < 0.001). An increase in the following parameters was noted in concussion vs age-matched controls: dilation release amplitude (0.54 ± 0.96 vs 0.36 ± 0.05 mm; P < 0.001) and latency (0.25 ± 0.05 vs 0.21 ± 0.02 s; P < 0.001). Subjects with concussion with photosensitivity exhibited increased dilation release amplitudes (P < 0.001).

Conclusions:
Individuals with sport concussion had impairment in pupillary constriction velocities, latency, and diameter in more than 1 year after concussion. The increase in dilation release amplitude among subjects with concussion might serve as a biomarker in diagnosing the underlying symptom of photosensitivity. The iPhone-based pupillometry could serve as a convenient and diagnostic tool in diagnosing these symptoms.

Published: February 2024

We characterize the equation of state (EoS) of the SU(N>2) Fermi-Hubbard Model (FHM) in a two-dimensional single-layer square optical lattice. We probe the density and the site occupation probabilities as functions of interaction strength and temperature for N=3, 4, and 6. Our measurements are used as a benchmark for state-of-the-art numerical methods including determinantal quantum Monte Carlo and numerical linked cluster expansion. By probing the density fluctuations, we compare temperatures determined in a model-independent way by fitting measurements to numerically calculated EoS results, making this a particularly interesting new step in the exploration and characterization of the SU(N) FHM.

Developing meaningful leadership in organizations: Evidence from a cross-case analysis in India
Authors: Pattanayak Anindya , Majhi Siddharth Gaurav 
Published: February 2024

Purpose
The extant organizational leadership literature acknowledges the utility of pursuing meaningful leadership, yet the scarcity of meaningful leaders persists. This paper compares two cases to elicit the factors distinguishing successful and unsuccessful meaningful leadership.

Design/methodology/approach
This paper delves into the strategies and practices of leaders in two organizations, and data are collected in the form of field notes of participant observations, and informal conversations with the members of both organizations. It seeks to unveil the defining characteristics of a leader who fosters member meaningfulness (Organization X) compared to one who does not (Organization Y).

Findings
The paper highlights distinct strategies that contribute to meaningful leadership. Effective leaders emphasize broader objectives, align values, adopt participatory leadership, mitigate meaninglessness, and promote continuous learning and growth. Conversely, ineffective leaders prioritize short-term goals, overlook value alignment, and lack participative engagement; together, these factors enable leaders to inspire, engage, and guide their teams with a sense of meaning.

Practical implications
By acknowledging that meaningful leaders may not be easily developed, organizations can shift focus towards identifying and nurturing such leaders, enhancing their capacity to foster genuine meaning among members and thereby improving overall organizational effectiveness.

Originality/value
This paper’s unique contribution lies in its comparative analysis of real-world cases, illuminating the specific practices that underlie meaningful leadership. By delineating the critical factors contributing to meaningfulness, this research lays a foundation for organizations to locate and cultivate leaders capable of engendering authentic meaning within their teams.
CEO dark triad traits and organization COVID-19 response: the mediating effect of COVID-19 anxiety and moderating effect of follower self-leadership
Authors: Williams Ethlyn A. , McCombs Kate M. , Pillai Rajnandini , Lowe Kevin B. 
Published: February 2024

PurposeThis research aims to examine the influence of Chief Executive Officer (CEO) dark triad traits, follower COVID-19 anxiety and self-leadership on follower evaluations of the effectiveness of organizations’ response to the COVID-19 pandemic crisis.Design/methodology/approachIn this paper data were collected over two time periods. At time 1, mid-October 2021, 650 participants responded to questions on their CEO’s leadership traits and self-leadership. At time 2, (3-week lag) 275 matched individual responses provided followers’ evaluations of the effectiveness of the organization’s COVID-19 response and follower self-leadership.FindingsCEO dark triad traits had direct and indirect negative effects on followers’ evaluations of the organization’s COVID-19 response (through COVID-19 anxiety). Follower self-leadership mitigated the negative effects.Research limitations/implicationsBy examining the moderating role of self-leadership, we can offer organizations evidence-based strategies to mitigate some harmful effects of leaders exhibiting dark triad traits.Practical implicationsGiven that organizations are still dealing with the ongoing ramifications of COVID-19 and planning for future crises, our findings emphasize the negative effects of dark traits on COVID-19 anxiety, and in turn, on follower’s evaluation of effective organization response to a crisis, highlighting the importance of top-level leader selection.Social implicationsOur results bolster Manz’s (1986) argument that self-leadership might be key to achieving peak performance in organizations and important for follower well-being.Originality/valueThis study of dark traits is especially important in a crisis context to understand how leaders affect followers’ perceptions about organizational outcomes and factors that might mediate or moderate the negative impact. Despite interest in understanding leadership during a crisis, the majority of research is focused on positive traits of leaders (Palmer et al., 2020).
