Study Design.

Retrospective cohort comparison study.

Objective.

To compare perioperative outcomes, radiographic parameters, and patient reported outcome measures (PROMs) between minimally invasive unilateral laminotomy with bilateral decompression (MIS-ULBD) versus MIS transforaminal lumbar interbody fusion (MIS-TLIF) for treatment of low-grade lumbar degenerative spondylolisthesis.

Summary of Background Data.

While lumbar degenerative spondylolisthesis is a common condition, optimal surgical treatment remains controversial. Newer MIS techniques, which preserve bone, paraspinal musculature, and posterior midline stabilizers, are thought to reduce the risk of iatrogenic instability and may obviate the need for fusion. However, few comparative studies of MIS techniques for low-grade lumbar degenerative spondylolisthesis currently exist.

Methods.

Consecutive patients with low-grade (Meyerding grade I or II) lumbar degenerative spondylolisthesis treated with single-level MIS-ULBD or MIS-TLIF were identified retrospectively from a prospectively collected spine surgery registry from April 2017 – November 2021. Perioperative outcomes, radiographic data, and PROMs were assessed.

Results.

A total of 188 patients underwent either MIS-ULBD or MIS-TLIF (79 MIS-ULBD and 109 MIS-TLIF). Patients who underwent MIS-ULBD tended to be older, had higher Charlson Comorbidity Index, lower mean percentage back pain, higher percentage of L4/L5 pathology, shorter operative time, lower estimated blood loss, and lower postoperative pain (P<0.05). In both groups, there were statistically significant improvements at 1 year for five out of the six PROMs studied: Oswestry Disability Index (ODI), visual analog scale (VAS)-back pain, VAS-leg pain, Short Form 12 Physical Component Score (SF12-PCS), and Patient-Reported Outcomes Measurement Information System (PROMIS) (P<0.05). On multivariate analysis controlling for confounders, there were no associations between procedure type and achieving MCID at 1 year in any of the PROMs studied.

Conclusions.

The current study suggests that both MIS-ULBD and MIS-TLIF result in significant improvements in pain and physical function for patients with low-grade lumbar degenerative spondylolisthesis.

Systematic Review of the “Pragmatism” of Pragmatic Critical Care Trials
Authors: Palakshappa Jessica A. , Gibbs Kevin W. , Lannan Margo T. , Cranford Anna R. , Taylor Stephanie P.
Published: July 2022

OBJECTIVES:

To assess the pragmatism of published critical care randomized controlled trials self-described as pragmatic using a validated tool.

DATA SOURCES:

Medical Literature Analysis and Retrieval Online database and PubMed interface from inception to November 1, 2021.

STUDY SELECTION:

We performed a systematic search of randomized controlled trials evaluating interventions for critically ill adults that self-identified as pragmatic in title or abstract.

DATA EXTRACTION:

Reviewers independently performed study selection and data extraction in duplicate; discrepancies were resolved by consensus. Pragmatism was assessed independently in duplicate by trained reviewers using the Pragmatic-Explanatory Continuum Indicator Summary 2 (PRECIS-2), a validated tool designed to represent how explanatory/pragmatic a trial is on the pragmatic to explanatory continuum. Trials were scored in nine domains on a 5-point continuum (from 1 = very explanatory to 5 = very pragmatic). Discrepancies of greater than 2 points were adjudicated by consensus discussion.

DATA SYNTHESIS:

The search resulted in 284 studies; 56 met eligibility criteria. Forty-one of the trials had a discrepancy in at least one domain that required consensus discussion, most commonly in domains of eligibility and follow-up. Twelve studies (21.4%) were scored as “overall pragmatic,” defined as score of greater than 4 in five domains provided the scores in the remaining domains were three. The overall PRECIS-2 score of self-identified pragmatic studies increased from 1995 to 2021 suggesting increasing pragmatism over time. Pragmatic trials were more likely to have a waiver of informed consent (p = 0.05).

CONCLUSIONS:

The number and pragmatism of self-identified pragmatic trials have increased, particularly in the past decade. However, less than one-quarter of these trials that use the term pragmatic in title or abstract were retrospectively rated as pragmatic. Our results support the concept that trials are designed on a spectrum of pragmatic to explanatory. Advances in the design and reporting of critical care trials are needed to ensure their real-world applicability.

Published: July 2022

OBJECTIVES:

In mechanically ventilated patients, awareness with paralysis (AWP) can have devastating consequences, including post-traumatic stress disorder (PTSD), depression, and thoughts of suicide. Single-center data from the emergency department (ED) demonstrate an event rate for AWP factors higher than that reported from the operating room. However, there remains a lack of data on AWP among critically ill, mechanically ventilated patients. The objective was to assess the proportion of ED patients experiencing AWP and investigate modifiable variables associated with its occurrence.

DESIGN:

An a priori planned secondary analysis of a multicenter, prospective, before-and-after clinical trial.

SETTING:

The ED of three academic medical centers.

PATIENTS:

Mechanically ventilated adult patients that received neuromuscular blockers.

INTERVENTIONS:

None.

MEASUREMENTS AND MAIN RESULTS:

All data related to sedation and analgesia were collected. AWP was the primary outcome, assessed with the modified Brice questionnaire, and was independently adjudicated by three expert reviewers. Perceived threat, in the causal pathway for PTSD, was the secondary outcome. A total of 388 patients were studied. The proportion of patients experiencing AWP was 3.4% (n = 13), the majority of whom received rocuronium (n = 12/13; 92.3%). Among patients who received rocuronium, 5.5% (n = 12/230) experienced AWP, compared with 0.6% (n = 1/158) among patients who did not receive rocuronium in the ED (odds ratio, 8.64; 95% CI, 1.11–67.15). Patients experiencing AWP had a higher mean (sd) threat perception scale score, compared with patients without AWP (15.6 [5.8] vs 7.7 [6.0]; p < 0.01).

CONCLUSIONS:

AWP was present in a concerning proportion of mechanically ventilated ED patients, was associated with rocuronium exposure in the ED, and led to increased levels of perceived threat, placing patients at greater risk for PTSD. Studies that aim to further quantify AWP in this vulnerable population and eliminate its occurrence are urgently needed.

Published: July 2022

Fetal growth restriction (FGR) is a common complication of pregnancy associated with higher rates of perinatal mortality and morbidity, as well as a variety of long-term adverse outcomes. To standardize the clinical practice for the management of FGR in China, Fetal Medicine Subgroup, Chinese Society of Perinatal Medicine, Chinese Medical Association and Maternal-Fetal Medicine Committee, Chinese Society of Obstetrics and Gynecology,Chinese Medical Association organized an expert committee to provide official consensus-based recommendations on FGR. We evaluated the evidence provided by relevant high-quality literature, performed a three-round Delphi study and organized face-to-face meetings with experts from multidisciplinary backgrounds. The consensus includes the definition, prenatal screening, prevention, diagnosis, monitoring and management of FGR.
Histological evidence supporting the durability of successful radiofrequency renal denervation in a normotensive porcine model
Authors: Sharp Andrew S.P. , Tunev Stefan , Schlaich Markus , Lee David P. , Finn Aloke V. , Trudel Julie , Hettrick Douglas A. , Mahfoud Felix , Kandzari David E.
Published: July 2022

Background:

Sustained blood pressure reductions after radiofrequency (RF) renal denervation (RDN) have been reported to 3 years in patients with uncontrolled hypertension. However, mechanistic data to support procedural durability are lacking. We aimed to quantify the long-term nerve anatomic and functional effects of RF RDN in a preclinical model.

Methods:

Bilateral RF RDN was performed in 20 normotensive swine. Renal tissue samples were obtained in the RDN-treated groups at 7 (n = 6), 28 (n = 6), and 180 days (n = 8) postprocedure for quantification of cortical norepinephrine (NE) levels and renal cortical axon density. Tissue fibrosis, necrosis and downstream nerve fiber atrophy (axonal loss) were also scored for each sample. Three additional untreated groups (n = 6, n = 6 and n = 8, respectively) served as control.

Results:

Pathologic nerve changes were characterized by necrosis in the ablated region at 7 days that partially resolved by 28 days and fully resolved at 180 days. Axonal loss was apparent within and downstream to the ablation regions and was evident at 7, 28 and 180 days in the main vessel and branch vessels. Consequently, renal cortical axon density and corresponding cortical NE levels were significantly reduced at 7 days in the RDN vs. control group and remained suppressed at 180 days.

Conclusions:

Reductions in renal NE, cortical axon density and downstream axonal loss caused by axonal destruction persisted through 180 days post-RDN in a normotensive swine model. These results suggest functional nerve regrowth after RF RDN is unlikely and support published clinical evidence that the procedure results in durable blood pressure reduction.
Immunoglobulin A (De Novo) Vasculitis After mRNA Moderna COVID-19 Vaccination
Authors: Aguilar-Aragon Javier Antonio , Mauro Anna Grace
Published: July 2022

Concurrent with the administration of vaccines for the novel coronavirus (COVID-19), there have been many reported adverse effects, and many of them anticipated as with any vaccine administration. This case report, however, focuses on a patient who, shortly after receiving the first dose of the Moderna COVID-19 vaccine, developed a pruritic maculopapular rash with typical distribution and clinical characteristics, along with high levels of immunoglobulin A (IgA), consistent with IgA vasculitis, formerly known as Henoch-Schonlein purpura. Although there are reported cases of IgA vasculitis after different vaccine administrations, to our knowledge, there are no reports of development of this condition after COVID-19 vaccination. The patient did not have any other triggering events or factors that could be attributed to the development of this pathology. This case describes the development of IgA vasculitis after the COVID-19 vaccination.

Authors: Masoudian Pourya , Kwok Chanel , Li Pen , Hosseini Sarah , Zhang Tinghua , Amjadi Kayvan
Published: July 2022

Background:

Indwelling pleural catheters (IPCs) reduce dyspnea and improve quality of life in patients with malignant pleural effusions (MPEs). Data on outcomes of MPEs secondary to metastatic melanoma managed with IPCs are scarce. We aimed to evaluate outcomes of patients receiving IPCs for MPEs secondary to melanoma compared with other malignancies.

Methods:

We identified patients from our prospectively collected database of all patients who had an IPC insertion for MPEs at our tertiary care center for melanoma between May 2006 and November 2018 and for nonmelanoma between May 2006 and June 2013. Chart reviews were conducted to obtain patient demographics, catheter complications, time of IPC removal or death, x-ray imaging, and pleural fluid characteristics.

Results:

We identified 27 MPEs because of melanoma and 1114 because of nonmelanoma malignancies treated with IPC. The most frequent complication was pleural fluid loculation requiring fibrinolytics which was significantly higher in the melanoma (14.8%) compared with the nonmelanoma group (3.8%; P=0.02). Cumulative incidence functions for catheter removal (P=0.8) or death with catheter in situ (P=0.3) were not significant between melanoma and nonmelanoma groups in competing risk analysis. Baseline radiographic pleural effusion scores were similar, but became significantly higher (increased pleural opacity) in the melanoma group at time points following IPC insertion (P<0.05).

Conclusion:

MPEs because of melanoma had a higher rate of loculations requiring fibrinolytics and less radiographic improvement after IPC insertion suggesting this patient subgroup has a more complicated pleural space which may be less responsive to drainage.

Pulmonary vein stump thrombosis (PVST) is uncommonly encountered postoperative in-situ thrombosis in the stump of pulmonary veins after lung resection. Data regarding the incidence and clinical behaviour of PVST are scarce. Thus, this study aims to investigate the incidence, clinical characteristics and outcome of PVST after lung resection in patients with lung cancer. Follow-up enhanced chest computed tomography (CT) scans acquired after the surgery were retrospectively reviewed to determine PVST presence for patients with lung cancer who underwent lung resection in two tertiary referral centres. Out of the 1885 patients with lung cancer who underwent lobectomy or more extensive lung resection, PVST was observed in 37 patients (2.0%) on their follow-up chest CT. Most stump thrombi were observed in the left superior pulmonary vein [35 (94.6%)] and in patients who underwent left upper lobectomy [34 (91.9%)]. At the last CT follow-up of each patient, 33 (89.2%) exhibited complete resolution, three partial resolution and one stabilization. Eleven (29.7%) patients received anticoagulant therapy after the diagnosis. The rate of complete PVST resolution did not differ significantly between the anticoagulation and nonanticoagulation groups. None of the PVST patients experienced systemic embolic events, regardless of anticoagulation. The PVST incidence diagnosed at routine chest CT follow-up following lung cancer surgery was 2%. PVST was characterized by a benign clinical course without progression and systemic embolization, regardless of anticoagulation. However, further studies are required to determine individualized therapeutic strategies, including anticoagulation.
Primary immune thrombocytopenia: a ‘diagnosis of exclusion’?
Authors: Visweshwar Nathan , Ayala Irmel , Jaglal Michael , Killeen Robert , Sokol Lubomir , Laber Damian A. , Manoharan Arumugam
Published: July 2022

Current diagnosis of primary immune thrombocytopenia (ITP) is presumptive, centered on excluding other causes of thrombocytopenia. The diagnosis of ITP is challenging because of the wide range of potential inherited and acquired causes of thrombocytopenia. The treatment of ITP is empiric with steroids, high-dose immunoglobulin, immunosuppressants and thrombopoietin agonists with potential side effects. We searched Medline and Cochrane databases, reviewed the study data and analyzed the individual diagnostic tests for their evidence-based role in the diagnosis of ITP. We then analyzed the strength of the scientific evidence for each diagnostic test in the diagnosis of ITP and identified gaps in the diagnostic accuracy. The diagnostic challenges in ITP include: insufficient evidence for the individual test for diagnosis of ITP, no standardized protocol/guideline for diagnosis, hurdles in accessing the available resources and failure to correlate the clinical data while reviewing the blood smear. We did not identify a diagnostic test that clinicians can use to confirm the diagnosis of ITP. In the absence of a diagnostic test of proven value in ITP, the clinician is best served by a comprehensive history and physical examination, complete blood count and review of the peripheral blood smear in evaluating thrombocytopenia.
Comparing the efficacy and safety of direct oral anticoagulants versus Vitamin K antagonists in patients with antiphospholipid syndrome: a systematic review and meta-analysis
Authors: Wu Xiaoling , Cao Shaobo , Yu Bo , He Tao
Published: July 2022

Thromboprophylaxis is the cornerstone strategy for thrombotic antiphospholipid syndrome (APS). Data comparing direct oral anticoagulants (DOACs) to Vitamin K antagonists (VKAs) in the secondary prevention of thrombosis in APS patients remain contentious.

We aim to review and analyse literature on the efficacy and safety of DOACs compared with VKAs in treating patients with APS. A literature search was performed from inception to 31 December 2021. Subgroups were analysed based on the risk stratification of APS profiles and different DOAC types.

A total of nine studies with 1131 patients were included in the meta-analysis. High-risk APS patients (triple positive APS) who used DOACs displayed an increased risk of recurrent thrombosis [risk ratio = 3.65, 95% confidence interval (95% CI): 1.49–8.93; I
2 = 29%, P = 0.005] compared with those taking VKAs. Similar risk of recurrent thrombosis or major bleeding was noted in low-risk APS patients (single or double antibody-positive) upon administering DOACs or VKAs. The utilization of Rivaroxaban was associated with a high risk of recurrent thromboses (RR = 2.63; 95% CI: 1.56–4.42; I
2 = 0, P = 0.0003), particularly recurrent arterial thromboses (RR = 4.52; 95% CI: 1.99–10.29; I
2 = 0, P = 0.18) in overall APS patients. Comparisons of the rate of recurrent thrombosis events and major bleeding events when using dabigatran or apixaban versus VKAs yielded no statistical differences.

In the absence of contraindications, this meta-analysis suggests that VKAs remain the first-choice treatment for high-risk APS patients, with DOACs a more appropriate option for low-risk APS patients. Different DOACs may exhibit different levels of efficacy and safety for thromboprophylaxis in APS patients and require further exploration.

Published: July 2022

Hemophilia is a rare constitutional hemorrhagic disorder. There is insufficient epidemiological data on hemophilia in Tunisia. To describe the epidemiological, clinical, therapeutic, and outcome of a cohort of patients with hemophilia in southern Tunisia. A retrospective study was conducted on patients with hemophilia at the Hemophilia Treatment Center of Southern Tunisia in Sfax over 38 years (from January 1982 to December 2020). Data were collected in a regional hemophilia registry of the South Tunisian center. We collected 141 cases of hemophilia, 85% of whom had hemophilia A and 15% had hemophilia B. The severe form represented 65%, followed by the moderate form at 25%. The prevalence of hemophilia was 4.4 in 100 000 population. Family history of hemophilia was found in 70%. The mean age of patients at diagnosis was 28 months. Hemophilia was detected in 87% of cases after hemorrhagic syndrome. Bleeding occurred mainly in hemarthrosis (73%), hematoma (70%), and visceral bleeding (28%). Intracranial bleeding occurred in 6% of cases. Thirty-six percent of patients were on prophylactic therapy. Hemophilic arthropathy was the most important orthopedic complication in our patients (38%). Inhibitory antibodies occurred in 16% of PWH. Transfusion-transmitted infections with HIV and hepatitis C were in 2 and 31% of cases, respectively. The prevalence of hemophilia is still underestimated in our center. The severe form of hemophilia is the most frequent. Hemophilic arthropathy was the most important complication in our patients. This showed that hemophilia is still a disabling disease in our country.
Self-reported sleep-disordered breathing and insomnia in association with hypertension: a community-based study in Eastern China
Authors: Wang Cuicui , Wang Bo , Liu Dong , Zhang Ya , Zheng Yanmin , Guo Li , Li Shengnan , Zuo Hui
Published: July 2022

Objective

We aimed to explore the associations of self-reported sleep-disordered breathing (SDB) and insomnia with hypertension based on a community-based survey among adults in Suzhou, Eastern China.

Methods

The Suzhou Food Consumption and Health Survey was conducted from 2018 to 2019. A multistage random sampling method was used to recruit potential participants. Associations of SDB and insomnia with hypertension were examined by multivariable logistic regression models with adjustment for covariates. In addition, sensitivity analysis was used to reinforce our findings.

Results

A total of 2728 participants were included in the final analysis. SDB (OR, 1.83; 95% CI, 1.44–2.34; P < 0.001) and insomnia (OR, 1.31; 95% CI, 1.04–1.65; P < 0.001) were significantly associated with prevalent hypertension after multivariable adjustments. In the subgroup analysis by age groups and sex, the association between SDB and hypertension persisted in all groups, whereas the association between insomnia and hypertension remained significant in males and different age groups. In addition, SDB was positively correlated with DBP. Notably, participants with comorbid SDB and insomnia had the highest risk for hypertension (OR, 1.95; 95% CI, 1.40–2.72; P < 0.001).

Conclusion

Both SDB and insomnia were associated with the prevalence of hypertension among the Chinese adults, whereas the comorbid conditions conveyed the highest risk for hypertension. Our findings provide a new insight for the potential pathogenesis of hypertension and a prevention strategy of hypertension among community adults.

Published: July 2022

Among obstructive sleep apnea (OSA) patients, there exists a high prevalence of hypertension. Determining the optimal blood pressure (BP) monitoring modality in this population will lead to a better understanding of hypertension profiles and a more accurate diagnosis of hypertension. PubMed, Ovid/Medline, Web of Science, Scopus, Cochrane Library, and CINAHL databases were screened, and the relevant articles regarding BP monitoring in OSA patient population were selected. Studies evaluating both ambulatory (ABPM) and office BP measurements were selected to be analyzed for the hypertension diagnosis specificity of ABPM measurement in OSA patients compared with office measurements. If reported, additional information regarding white-coat, masked hypertension, and circadian BP pattern prevalence was included. A cumulative analysis of five studies revealed a prevalence of hypertension based on BP to be 44%, whereas a cumulative analysis of four studies revealed a prevalence of hypertension based on ABPM to be 66%. Excluding a study with the nighttime assessment of hypertension reduced the cumulative prevalence of hypertension in OSA patients to 59%. The cumulative prevalence of Studies demonstrated the prevalence of masked and white-coat hypertension to be 34 and 9%, respectively. As a higher prevalence of hypertension was detected by ABPM and nighttime measurement, it can be deduced that ABPM is more sensitive in determining OSA patients with hypertension, and that nighttime ABPM further increases this sensitivity. The presence of masked and white-coat hypertension in OSA patients underlines the importance of correct hypertension diagnosis as it affects further management in this population with increased cardiovascular risk.
Volatile anesthesia versus propofol-based total intravenous anesthesia: A retrospective analysis of charts of patients who underwent elective digestive tract cancer curative surgeries
Authors: Zhang Ying , Wang Fang , Zhang Hui , Wei Yulong , Deng Yanan , Wang Dezhi
Published: July 2022

The surgical stress responses, surgeries, and anesthetics used during surgeries have effects on post-surgery complications and metastasis. Volatile and/or intravenous anesthetics are generally used for cancer curative surgeries. Therefore, appropriate selection of anesthetics should be considered for better clinical outcomes. The objectives of the study were to compare postoperative complications, the overall survival, and recurrence-free survival of patients who had received volatile anesthesia against those of patients who had received propofol-based total intravenous anesthesia for digestive tract cancer curative surgeries. Patients had received propofol-based total intravenous anesthesia (PA cohort, n = 120) or volatile anesthesia (VA cohort, n = 185) for elective digestive tract cancer curative surgeries. Patients with age > 50 years (P = .0399), body mass index ≥ 25 kg/m2 (P = .0423), cancer stage III (P = .0041), and cancer stage IV (P = .0189) were operated through volatile anesthesia. Females (P = .0346), disable patients (P = .0479), patients with Charlson Comorbidity Index 2 (P = .0449), patients with cancer stage 0 or I (P = .0141), and patients with cancer stage II (P = .0289) were operated through propofol-based total intravenous anesthesia. Postoperative complication(s) between patients of both cohorts were statistically same (P = .9217). After 3-years of the follow-up period, a total of 81 (44%) patients from the VA cohort and 63 (52%) patients from the PA cohort survived irrespective of any kind of disease(s) (P = .9918). Also, a total of 53 (29%) patients from the VA cohort and 42 (35%) patients from the PA cohort survived without progression of cancer (P = .9981) after 3-years. Age > 50 years (P = 0.0491), Charlson Comorbidity Index ≥ 3 (P = 0.0481), and cancer stage > II (P = .0412) were independent parameters for death of patients suffering from digestive tract cancer due to any reason(s) during 3-years of the follow-up period after surgeries. The selection of anesthetic agents for cancer curative surgeries does not affect survival during 3-years of follow-up and postoperative complication(s) of patients suffering from digestive tract cancer (Level of Evidence: III; Technical Efficacy Stage: 4).
A bibliometric and emerging trend analysis on stress granules from 2011 to 2020: A systematic review and bibliometrics analysis
Authors: Yu Haiyang , Chen Qinhao , Pan Yueyin
Published: July 2022

Background:

Stress granules (SGs) are the dense granules formed in the cytoplasm of eukaryotic cells in response to stress stimuli, such as endoplasmic reticulum stress, heat shock, hypoxia, and arsenate exposure. Although SGs have been attracting a lot of research attention, there is still a lack of systematic analysis of SGs in the literature.

Methods:

By analyzing the literature published in the Web of Science database using the R software, we extracted all the information related to SGs from the literature and cited references. The following information was included: publications per year, overall citations, top 10 countries, top 10 authors, co-author collaborations, top 10 institutions, critical areas, and top 10 cited research articles.

Results:

A total of 4052 articles related to SGs were selected and screened. These documents have been cited a total of 110,553 times, with an H-index of 126 and an average of 27.28 citations per article. The authors of the literature included in this study were from 89 different countries/regions. The United States and China had the highest number of publications and ranking institutions.

Conclusions:

This article presents essential insights on the characteristics and influence of SGs, demonstrating their indispensable role in immune regulation and other fields.
Evaluation of chest radiography and low-dose computed tomography as valuable screening tools for thoracic diseases
Authors: Kasuga Ikuma , Maezawa Hiromi , Gamo Sanae , Yokoe Yoshimi , Yanagihara Yuri , Sugiyama Tomoko , Tokura Michiyo , Okayama Mayumi , Ohtsubo Osamu
Published: July 2022

Background:

Recent studies have shown that low-dose computed tomography (LDCT) is effective for the early detection of lung cancer. However, the utility of chest radiography (CR) and LDCT for other thoracic diseases has not been as well investigated as it has been for lung cancer. This study aimed to clarify the usefulness of the veridical method in the screening of various thoracic diseases.

Methods:

Among individuals who had received general health checkups over a 10-year period, those who had undergone both CR and LDCT were selected for analysis. The present study included 4317 individuals (3146 men and 1171 women). We investigated cases in which abnormal opacity was detected on CR and/or LDCT.

Results:

A total of 47 and 124 cases had abnormal opacity on CR and LDCT, respectively. Among these, 41 cases in which the abnormal opacity was identified by both methods contained 20 treated cases. Six cases had abnormalities only on CR, and none of the cases required further treatment. Eighty-three cases were identified using LDCT alone. Of these, many cases, especially those over the age of 50 years, were diagnosed with thoracic tumors and chronic obstructive pulmonary disease, which required early treatment. In contrast, many cases of pulmonary infections have improved spontaneously, without any treatment.

Conclusion:

These results revealed that LDCT allowed early detection of thoracic tumors and chronic obstructive pulmonary disease, especially in individuals over the age of 50 years. CR is still a useful imaging modality for other thoracic diseases, especially in individuals under the age of 49 years.
Risk factors of trauma-induced thrombotic microangiopathy-like syndrome: A retrospective analysis
Authors: Lim Kyoung Hoon , Park Jinyoung , Cho Sung Hoon
Published: July 2022

Patients with trauma may develop thrombocytopenia. We encountered cases wherein patients experienced symptoms resembling thrombotic microangiopathies (TMAs) following severe trauma. As the condition of these patients did not meet the diagnostic criteria of thrombotic thrombocytopenic purpura and there was no mention of trauma among the several causes of TMAs, it was termed as “trauma-induced thrombotic microangiopathy-like syndrome” (t-TMAS). In this study, we aimed to analyze the risk factors that may affect the incidence of t-TMAS in patients with severe trauma. This retrospective study was conducted in the trauma intensive care unit at the Kyungpook National University Hospital between January 2018 and December 2019. The medical records of 1164 of the 1392 enrolled participants were analyzed. To assess the risk factors of t-TMAS, we analyzed age, sex, mechanism of trauma, abbreviated injury scale (AIS) score, injury severity score (ISS), hematological examination, and red blood cell volume transfused in 24 hours. Among the 1164 patients, 20 (1.7%) were diagnosed with t-TMAS. The univariate analysis revealed higher age, ISS, and myoglobin, lactate, creatine kinase-myocardial band (on admission), creatine phosphokinase, lactate dehydrogenase (LDH), and lactate (day 2) levels in the t-TMAS group than in the non-t-TMAS group. The red blood cell volume transfused in 24 hours was higher in the t-TMAS group than in the non-t-TMAS group. t-TMAS was more common in patients with injuries in the chest, abdomen, and pelvis (AIS score ≥3) than in those with head injuries (AIS score ≥3) alone. The higher the sum of AIS scores of the chest, abdomen, and pelvis injuries, the higher the incidence of t-TMAS. Multivariate analysis revealed age, ISS, and LDH level (day 2) to be independent predictors of t-TMAS. Trauma surgeons should consider the possibility of t-TMAS if thrombocytopenia persists without any evidence of bleeding, particularly among older patients with multiple severe torso injuries who have high LDH levels on day 2. Early diagnosis and treatment of t-TMAS could improve patients’ prognosis.

Published: July 2022

The relationship between sarcopenia and respiratory function has not been investigated in elderly Japanese orthopedic outpatients. This study aimed to assess the relationship between sarcopenia and respiratory function in elderly orthopedic outpatients in Japan.

Elderly outpatients (n = 102; aged ≥65 years) with orthopedic diseases were enrolled in the study. Muscle mass was measured using the bioelectrical impedance analysis. Grip strength and walking speed were measured (2 trials). The respiratory function (e.g., percent vital capacity [VC] and percent forced expiratory volume in 1 second) was also measured. The association between sarcopenia and respiratory function was assessed using logistic regression analysis, adjusting for sex, comorbidities, and smoking status.

The mean ages for men and women were 77.7 ± 8.3 and 76.5 ± 6.8 years, respectively, and the overall prevalence of sarcopenia was 25.5% (30.0% and 24.4% in men and women, respectively). The study demonstrated that low respiratory function, which was represented by decreased percent VC, was associated with sarcopenia in outpatients visiting an orthopedic department (odds ratio, 1.73; 95% confidence interval: 1.02–2.97).

Sarcopenia was significantly associated with a lower percentage of VC in orthopedic outpatients after adjustment for sex, comorbidity, and smoking. Further studies are needed to determine the causality.
Hyperfibrinolysis secondary to acquired factor XIII deficiency A case report
Authors: Gao Lingsu , Li Dengju , Ding Meiqi
Published: July 2022

Introduction:

Hyperfibrinolysis induced by factor XIII deficiency (FXIIID) is extremely rare, and patients with no manifestations of active bleeding can easily and frequently be neglected in clinical practice, leading to a missed diagnosis. Herein, we report a rare case of idiopathic FXIIID with secondary hyperfibrinolysis.

Patient concerns:

A 69-year-old man presented with ecchymosis of the right arm and chest wall.

Diagnosis:

Considering the clinical picture, coagulation function test results, and FXIII activity, the patient was finally diagnosed with hyperfibrinolysis secondary to acquired factor XIII deficiency.

Interventions:

The patient was treated with fresh frozen plasma, aminomethylbenzoic acid, a prothrombin complex, etamsylate, dexamethasone, and cryoprecipitate.

Outcomes:

The patient improved and was discharged after factor replacement therapy, and no further bleeding was reported 1 month after discharge.

Conclusion:

This case report illustrates that the complications of Factor XIII deficiency may include hyperfibrinolysis. Since timely diagnosis of FXIIID is challenging, detailed coagulation factor examinations are needed for definitive diagnosis. It has been suggested that gene testing and antibody testing can help in diagnosis. If ideal treatment is not available, alternative treatment should be provided to reduce bleeding.
Health economic evaluation of an mRNA high-risk human papillomavirus (HR-HPV) assay versus a DNA HR-HPV assay for the proposed French cervical screening programme
Authors: Dombrowski Caroline A. , Weston Georgie MF , Descamps Pr Philippe , Izopet Pr Jacques , Adams Elisabeth J. , Adams Elisabeth
Published: July 2022

Objective:

Population screening programmes must make good use of resources for the health system and users. To evaluate impacts of the type of diagnostic test in the new French cervical screening programme, an messenger ribonucleic acid (mRNA) high-risk human papillomavirus assay was compared to a deoxyribonucleic acid (DNA) high-risk human papillomavirus assay for a hypothetical cohort of women aged 25 to 65 years.

Perspective:

This evaluation takes the perspective of the French healthcare system.

Setting:

France

Methods:

A decision tree model reflecting the French cervical screening algorithms was parametrised using French cost and population data and the Danish Horizon study. The outcomes were total costs, and number of colposcopies, HPV tests and cytology tests for the cohort. One-way and probabilistic sensitivity analyses and scenarios analyses were conducted to test the robustness of results to parameter and structural uncertainty.

Results:

Adopting an mRNA versus DNA assay as part of national cervical screening in France is estimated to save €6.5 million (95% credibility intervals €-1.3 - €13.5 million) and prevent 47,795 (95% credibility intervals 35,309 - 60,139) unnecessary colposcopies, 38,666 unnecessary HPV tests and 121,670 cytology tests over two years for a cohort of 2,168,806 million women aged 25 to 65 years. Sensitivity analyses indicated robust results across a range of inputs.

Conclusion:

The choice of high-risk human papillomavirus assay makes a significant difference to resource use and costs and is important to consider when implementing cervical screening in France. Using an mRNA versus DNA assay can result in cost savings and reductions in unnecessary testing and procedures, which in turn benefits women and the health care system.
Evaluation of SARC-F and SARC-CalF for sarcopenia screening in patients with chronic musculoskeletal pain: A prospective cross-sectional study
Authors: Tsuji Hironori , Tetsunaga Tomoko , Tetsunaga Tomonori , Misawa Haruo , Oda Yoshiaki , Takao Shinichiro , Nishida Keiichiro , Ozaki Toshifumi
Published: July 2022

Objectives:

Early sarcopenia detection using screening tools, such as SARC-F and SARC-CalF, has been proven reliable. However, the relationship between chronic musculoskeletal pain with sarcopenia is unknown. This study assessed sarcopenia morbidity as well as the reliability of sarcopenia screening with SARC-F and SARC-CalF in patients with chronic musculoskeletal pain.

Methods:

Overall, 172 patients with chronic musculoskeletal pain were included in this cross-sectional study. All participants completed the SARC-F, SARC-CalF, numeric rating scale (NRS), and pain disability assessment scale (PDAS) assessments. Sarcopenia was diagnosed using the Asian Working Group for Sarcopenia criteria 2019. Correlations between SARC-F and SARC-CalF scores and each measured variable were evaluated using univariate and multiple linear regression analyses. A receiver operating characteristic curve analysis was conducted, and reliabilities of SARC-F and SARC-CalF scores for diagnosing sarcopenia were compared.

Results:

Thirty-nine patients were diagnosed with sarcopenia. Among these, 10 patients were <65 years old, and 29 were >65 years old. Both SARC-F and SARC-CalF scores significantly correlated with grip power, gait speed, skeletal mass index, numeric rating scale score, and PDAS score. In multiple linear regression analysis, SALC-F and SALC-CalF scores significantly correlated with PDAS score, skeletal mass index, and gait speed. The area under the curve were 0.70 for SARC-F and 0.88 for SARC-CalF; SARC-CalF had a significantly higher area under the curve than SARC-F.

Discussion:

Sarcopenia was diagnosed in patients aged <65 years with chronic musculoskeletal pain. SALC-F and SARC-CalF scores showed a significant correlation with disability due to pain and were reliable sarcopenia screening tools for chronic musculoskeletal pain. SARC-CalF was more reliable than SARC-F.

Authors: Sopracordevole Francesco , Clemente Nicolò , Papiccio Maria , Del Fabro Anna , Serri Matteo , Fichera Mariasole , Buttignol Monica , Giorda Giorgio , Delli Carpini Giovanni , Ciavattini Andrea
Published: July 2022

Objective:

To analyze the histopathological findings in postmenopausal women who underwent hysterectomy for postsurgical cervical stenosis, evaluating the incidental findings of preinvasive or invasive uterine and cervical disease.

Methods:

Retrospective case series of postmenopausal women who underwent hysterectomy for postsurgical cervical stenosis at Gynecological Oncology Unit of Istituto di Ricovero e Cura a Carattere Scientifico Centro di Riferimento Oncologico Aviano—National Cancer Institute from January 2014 to January 2021.

Results:

During the study period, 36 women underwent hysterectomy for postsurgical cervical stenosis at our institution. Cervical stenosis occurred 10.2 ± 5.6 years from the onset of menopause. In particular, 26 (72.2%) patients underwent a single loop electrosurgical excision procedure or carbon dioxide (CO2)-laser conization before the onset of stenosis. The remaining 10 (27.8%) women had multiple surgical excision before the onset of stenosis. At the final histopathological analysis, 17 (47.2%) patients had a preinvasive or invasive gynecological disease. In particular, 9 cases of cervical disease (including 1 case of endocervical squamous cell carcinoma pT1a) and 6 cases of endometrial hyperplasia emerged. Also, 2 cases of tubo-ovarian diseases were found.

Conclusions:

Postsurgical cervical stenosis is a challenging clinical condition, especially in women treated for cervical intraepithelial neoplasia or microinvasive cervical cancer. As shown, cervical stenosis can prevent an adequate gynecological follow-up and a prompt diagnosis of malignancies. Therefore, postmenopausal women with cervical stenosis should be carefully counseled, and hysterectomy could be a reasonable option, especially in those cases in which a conservative approach is not feasible, failed, or is not accepted by the patient.
Sequence CLCN1 and SCN4A genes in patients with nondystrophic myotonia in Chinese people
Authors: Meng Yan-Xin , Yu Mei , Liu Chunmiao , Zhang Haijuan , Yang Yuxiu , Zhang Jing
Published: July 2022

Background:

This study aimed to characterize the genetic, pathological, and clinical alterations of 17 patients in China presenting with nondystrophic myotonia (NDM) and to analyze the relationship between genotype and clinical phenotype.

Methods:

CLCN1 and SCN4A genes in patients with clinical features and muscle pathology indicative of NDM were sequenced. Furthermore, KCNE3 and CACNA1S genes were assessed in patients with wild-type CLCN1 and SCN4A.

Results:

Patients may have accompanying atypical myopathy as well as muscle hypertrophy, secondary dystonia, and joint contracture as determined by needle electromyography. All the study participants were administered mexiletine in combination with carbamazepine and showed significant improvements in myotonia symptoms in response to this therapy. CLCN1 gene mutation was detected in 8 cases diagnosed with myotonia congenital using gene screening. The detected mutations included 5 missense, 2 nonsense, 1 deletion, and 2 insertions. Further gene analysis showed 4 mutations in the SCN4A gene in patients diagnosed with paramyotonia congenita.

Conclusions:

Myotonia congenita and paramyotonia congenita are the predominant forms of NDM in China. NDM may be best diagnosed using genetic analysis in associated with clinical features.
Effect of vitamin D on endothelial and ventricular function in chronic heart failure patients: A prospective, randomized, placebo-controlled trial
Authors: Woo Jong Shin , Woo Yeongmin , Jang Jeong Yoon , Ha Sang Jin
Published: July 2022

Background:

Low 25-hydroxyvitamin D (25OHD) levels are common in patients with chronic heart failure (HF) and are associated with increased mortality risk. This study aimed to establish the safety and efficacy of oral vitamin D3 (cholecalciferol) supplementation and its effect on endothelial and ventricular function in patients with stable HF.

Methods:

This study was an investigator-initiated, multicenter, prospective, randomized, placebo-controlled trial. Seventy-three HF patients with 25OHD levels < 75 nmol/L (30 ng/mL) were randomized to receive 4000 IU vitamin D daily or a placebo for 6 months. The primary endpoint was a change in endothelial function between the baseline and after 6 months as assessed using EndoPAT. Secondary endpoints included changes in echocardiographic parameters and differences in quality of life (6-min walking test and New York Heart Association functional status) at 6 months.

Results:

There were no adverse events in either group during the study period. Vitamin D supplementation did not improve endothelial dysfunction (EndoPAT: baseline, 1.19 ± 0.4 vs 6 months later, 1.22 ± 0.3, P = .65). However, patients’ blood pressure, 6-min walking distance, and EQ-5D questionnaire scores improved after vitamin D treatment. In addition, a significant reduction in the left atrial diameter was observed.

Conclusion:

A daily vitamin D dose of 4000 IU for chronic HF appears to be safe. This dosage did not improve endothelial function but did improve the 6-min walk distance, symptoms, and left atrial diameter at 6 months.
Steroid-induced delayed diagnosis of primary vitreoretinal lymphoma with ghost brain tumor: A case report
Authors: Kau Hui-Chuan , Wang Cheng-Jen , Tsai Chieh-Chih
Published: July 2022

Rationale:

Primary vitreoretinal lymphoma is a great masquerader and provides a diagnostic challenge.

It is most frequently misdiagnosed as a chronic uveitis. Steroid treatment for presumed uveitis can interfere with the correct diagnosis of vitreoretinal lymphoma. Herein, we present a case of primary vitreoretinal lymphoma in which the correct diagnosis was delayed by short-term steroids until 2 years later.

Patient concerns:

A 45-year-old woman presented with floaters and blurred vision in her right eye for 3 months. An ocular examination revealed dense vitreous cells. Three months later, she developed headache and suicidal ideation after taking a 3-week medication of oral steroid medication from another eye clinic. Brain magnetic resonance imaging revealed a tumor involving the corpus callosum and periventricular region.

Interventions:

Vitreous biopsy and repeated brain biopsies were carried out for the patient.

Diagnosis:

A brain biopsy was performed for the first time, and a vitreous biopsy was performed when steroid medication was suspended for 20 and 41 days, respectively. Both biopsies were negative for the presence of malignant cells. Follow-up magnetic resonance imaging revealed complete remission of the brain tumor. Two years later, the tumor recurred in the optic chiasm. Diffuse large B-cell lymphoma was confirmed by a second brain biopsy.

Outcome:

The patient had complete tumor remission after receiving brain radiation therapy and chemotherapy.

Lessons:

Vitreoretinal lymphoma is difficult to diagnose owing to its rarity, masquerading presentation, and steroid-induced apoptosis of lymphoma cells. Physicians should consider vitreoretinal lymphoma as an important differential diagnosis in patients presenting with chronic uveitis and use steroids cautiously before making a definitive diagnosis.
