Published: September 2021

Background:

This study aimed to assess the efficacy and safety of minimally invasive percutaneous nephrolithotomy (MPCNL) versus standard percutaneous nephrolithotomy in patients with renal and upper ureteric stones.

Methods:

We conducted a pooled analysis on randomized controlled trials (RCTs). The eligible RCTs were selected from the following databases: MEDLINE, Embase, Web of Science, and the Cochrane Library. The reference lists of retrieved studies were also investigated.

Results:

Our analysis included 10 RCTs with 1612 patients. Pooled data from 10 RCTs revealed the following: stone-free rate (odds ratio = 1.46, 95% confidence interval (CI) [1.12,1.88], P = .004), operative time (mean difference [MD]  = 4.10, 95% CI [–1.37,9.56], P = .14), length of hospital stay (MD = –15.31, 95% CI [–29.43,–1.19], P = .03), hemoglobin decrease (MD = –0.86, 95% CI [–1.19,–0.53], P < .00001), postoperative fever (MD = 0.83, 95% CI [0.49,1.40], P = .49), and urine leakage (MD = 0.59, 95% CI [0.25,1.37], P = .22). Besides, we performed sub-group analysis based on vacuum suction effect and multiple kidney stones. For vacuum suction effect, it revealed the following: stone-free rate in vacuum suction group (P = .007) and in non-vacuum suction group (P = .19). Operative time in vacuum suction group (P = .89), non-vacuum suction group (P = .16). Postoperative fever in vacuum suction group (P = .49), non-vacuum suction group (P = .85).

Conclusion:

This pooled analysis indicated that MPCNL was a safe and effective method for treating renal stones compared with standard percutaneous nephrolithotomy. Besides, the vacuum suction effect in MPCNL played a more important role. When it comes to multiple or staghorn stones, the longer operative time in MPCNL could not be ignored.
HIV prevalence in patients with cervical carcinoma
Authors: Mohosho Mokoena Martins
Published: September 2021

The Human Immunodeficiency Virus (HIV) seropositive prevalence among women with cervical cancer varies in different parts of the world and even within a country. This study aimed to document the prevalence of HIV infection in women with newly diagnosed cervical cancer at a secondary hospital in South Africa.

This study is a retrospective review of records of 89 women who were newly diagnosed with cervical cancer between 01 June 2010 and 31 May 2013 at Pelonomi Hospital, Mangaung, South Africa. Data such as age, parity, gravidity, marital status, occupation, HIV status, CD4 count, on anti-retroviral treatment, clinical stage of disease were retrieved from the case files, the Meditech-patient record and Disa laboratory system. Data analysis was done using the SAS statistical package.

HIV-seropositive prevalence was 52.4%, with the highest prevalence (91.3%) in the age group 40 years and younger. In HIV-positive women, the mean CD4 cell count was 280 cell/mm3 and 43% of them were not on anti-retroviral treatment. The majority (86%) of all patients presented with late stage disease (International Federation of Gynecology and Obstetrics Stage III and IV) when newly diagnosed with cervical cancer.

This study highlights high HIV-seropositive prevalence; severe immunosuppression and late presentation of the disease in women newly diagnosed with cervical cancer. Cervical cancer screening programs need to be fully reinforced into existing HIV health care services to allow for ideal prevention and early detection of the disease. Anti-retroviral treatment needs to be prioritized for HIV-positive women.

Published: September 2021

To investigate the clinical and pathological characteristics in patients with pulmonary inflammatory pseudotumors (PIP).

This retrospective study included 31 patients with PIP from 2001 to 2019. Preoperative computed tomography scan was performed in all patients. Clinical and pathological characteristics were collected and analyzed.

Thirty-one patients (16 female and 15 male) were recruited, with a median age of 57 years (range, 11–72 years). Eight (25.8%) patients were asymptomatic, and the others had symptoms characterized by cough with sputum, chest and back pain, dry cough, fever and blood in sputum, or hemoptysis. All cases were single lesions, including 23 cases in the right lung, and 8 cases in the left lung. Computed tomography scan demonstrated irregular lobulated nodules or masses in 14 patients, and regular round or oval nodules or masses in 11 cases. The blurred edge of tumors and spiculation was found in 12 cases. Microscopic results were characterized by the collection of inflammatory mesenchymal cells. Immunohistochemical examination showed vimentin, smooth muscle actin, and anaplastic lymphoma kinase positive. Complete tumor resection was obtained in all cases. No recurrence or metastasis was observed during the follow-up period.

PIP has a variety of manifestations. Preoperative diagnosis is difficult to reach. The final diagnosis still depends on the pathological and immunohistochemical examination. Complete surgical resection is the main treatment at present, and the overall prognosis is good.
Comparison of attitudes towards the service connection claims process among veterans filing for PTSD and veterans filing for musculoskeletal disorders
Authors: Spinola Suzanne , Fenton Brenda T. , Meshberg-Cohen Sarah , Black Anne C. , Rosen Marc I.
Published: September 2021

Many veterans have negative views about the service connection claims process for posttraumatic stress disorder (PTSD), which likely impacts willingness to file service connection claims, re-file claims, and use Veterans Healthcare Administration care. Nevertheless, veterans have reported that PTSD claims are important to them for the financial benefits, validation of prior experience and harm, and self-other issues such as pleasing a significant other. It is unknown if reported attitudes are specific to PTSD claimants or if they would be similar to those submitting claims for other disorders, such as musculoskeletal disorders. Therefore, the purpose of this study was to compare attitudes and beliefs about service connection processes between veterans submitting service connection claims for PTSD and musculoskeletal disorders.

Participants were Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn veterans filing service connection claims for PTSD (n = 218) or musculoskeletal disorder (n = 257) who completed a modified Disability Application Appraisal Inventory. This secondary data analysis using multiple regression models tested the effect of demographics, clinical characteristics, and claim type on 5 Disability Application Appraisal Inventory subscales: Knowledge about service connection claims, Negative Expectations about the process, and importance of Financial Benefits, importance of Validation of veteran's experience/condition, and importance of Self-Other attitudes.

The PTSD group assigned significantly less importance to financial benefits than the musculoskeletal disorder group. In addition, the subset of the PTSD group without depression had significantly more Negative Expectations than musculoskeletal disorder claimants without depression. Negative Expectations did not differ between the PTSD and musculoskeletal disorder groups with depression. Depression was significantly positively associated with Negative Expectations, importance of Financial Benefits, and importance of Validation.

Most perceptions around seeking service connection are not specific to PTSD claimants. Depression is associated with having negative expectations about service connection claims and motivations to file claims. Addressing depression and negative expectations during the compensation and pension process might help veterans at this important point of contact with Veterans Healthcare Administration services.
Patient with sick sinus syndrome and implanted dual-chamber pacemaker with reduced P-wave duration following low interatrial septal pacing
Authors: Mercik Jakub , Gajek-Marecka Aleksandra , Zawadzki Jacek Marcin , Sławuta Agnieszka , Gajek Jacek
Published: September 2021

Introduction:

A dual-chamber pacemaker (DDD/R) for a sinus node disease is sometimes referred to as a physiological pacemaker as it maintains atrioventricular synchrony, however several clinical trials have proved its inferiority to a nonphysiological single-chamber ventricular back-up pacing.

Patient concerns:

A subject of the study is a 74-year-old woman with a sick sinus syndrome (SSS) and a previously implanted physiological DDD/R pacemaker. The SSS was diagnosed because of patient's very slow sinus rhythm of about 36 bpm, and due to several episodes of dizziness. After the DDD/R implantation the percentage of atrial pacing approached 100%, with almost none ventricular pacing.

Diagnoses:

Sick sinus syndrome, complete Bachmann's bundle block, atrial fibrillation, atrial flutter.

Interventions:

The patient was previously implanted with a physiological DDD/R pacemaker. Several years after the implantation, the atrial fibrillation was diagnosed and the pulmonary vein isolation was then performed by cryoablation. During the follow-up after pulmonary vein isolation, the improvement of mitral filling parameters was assessed using echocardiography. Shortly thereafter the patient developed the persistent paroxysm of a typical atrial flutter which was successfully terminated using a radiofrequency ablation. No recurrence thereof has been observed ever since (24 months).

Outcomes:

The atrial electrode of the pacing system was implanted within the low interatrial septal region that resulted in a reduced P-wave duration compared to native sinus rhythm P-waves. The said morphology was deformed because of the complete Bachmann bundle block. That approach, despite a nonphysiological direction of an atrial activation, yielded relatively short P-waves (paced P-wave: 179 ms vs intrinsic sinus P-wave: 237 ms). It also contributed to a significantly shorter PR interval (paced PR: 204 ms vs sinus rhythm PR: 254 ms).

Conclusions:

The authors took into consideration different aspects of alternative right atrial pacing sites. This report has shown that in some patients with a sinus node disease, low interatrial septal pacing can reduce the P-wave duration but does not prevent from the development of atrial arrhythmias.
Effects of non-pharmacological interventions on anxiety, depression, and sleep quality in patients with postoperative glaucoma
Authors: Liu Jiong , Cao Lei , Yang Guang , Zhou Runhai
Published: September 2021

Background:

Glaucoma is the second most-common blinding ophthalmic disease in the world, and its incidence has been rising year by year in recent years. Currently, the main treatment of glaucoma still relies on surgery. Glaucoma patients often suffer from various psychological problems like anxiety and depression not only because of the lack of understanding of the surgical treatment of glaucoma, but also the long-term stress and the poor prognosis. As alternative therapies, non-pharmacological interventions can greatly alleviate psychological burdens and improve sleep quality in surgically treated glaucoma patients. Randomized controlled trials of non-pharmacologic interventions for glaucoma have been reported, although the results remain conflicting. Evidences for determining the efficacy of non-pharmacologic interventions for glaucoma are scant. This study aims to assess the effects of non-pharmacological interventions on anxiety, depression, and sleep quality in patients with postoperative glaucoma through a network meta-analysis.

Methods:

A systematic search of relevant literatures published before August 2021 about the effects of non-pharmacological interventions on anxiety, depression, and sleep quality in patients with postoperative glaucoma will be performed in Wanfang, VP Information Chinese Journal Service Platform, China National Knowledge Infrastructure, Chinese BioMedicine Literature Database, Pubmed, Embase, Cochrane, and Web of science. Two reviewers will be independently responsible for literature screening and selection, quality assessment, and data extraction. WinBUGS 1.4 will be used for the network meta-analysis.

Results:

This meta-analysis will provide additional and stronger evidences for non-pharmacological interventions on anxiety, depression, and sleep quality in patients with postoperative glaucoma, which will help clinicians and decision makers to make an optimal therapeutic strategy.

Conclusion:

This study will provide a reliable evidence-based basis for the clinical application of non-pharmacological interventions on anxiety, depression, and sleep quality in patients with postoperative glaucoma.

Ethics and dissemination:

Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. This review would be disseminated in a peer-reviewed journal or conference presentations.

Published: September 2021

The turnover rate among kindergarten teachers in advanced countries is extremely high. As such, there is an urgent need to determine the reasons for this turnover and to identify ways to prevent it. The current study investigates the individual and environmental factors that impact kindergarten teachers’ willingness to continue working.

A total of 600 kindergarten teachers in Japan participated in this study. Participants responded to questionnaires regarding their willingness to continue working, mental health, work engagement, and the availability of social support. Multiple logistic regression analysis was used to analyze participants’ data, with willingness to continue working for 5 or more years as the dependent variable. Additionally, Spearman rank correlation was used to examine the correlations between factors associated with willingness to continue working.

Factors such as older age, living with a spouse, caring for younger children (up to 2 years old) at work, good mental health, and higher work engagement were significantly associated with teachers’ higher willingness to continue working. Factors such as marriage, health and family problems, overtime work, issues with workplace childcare, and education policy, working time/day problems, human relations, and difficulties taking care of children were correlated with teachers’ lack of willingness to continue working.

The findings of this cross-sectional study suggest that welfare benefits and individual support systems could be key elements to encourage kindergarten teachers to continue working and could lead to their improved job satisfaction and mental health. Balanced work conditions and workers’ high agreement with their workplace's overall childcare or educational policies may lead to lower turnover. Some programs – such as relationship counselling – could have a positive impact on teachers’ mental health and job satisfaction.

Published: September 2021

Background:

Constipation is one of the common complications of thoracolumbar compression fractures, which seriously affects the quality of life and increases pain of patients. External treatment of traditional Chinese medicine (TCM) has been widely used clinically for constipation after thoracolumbar compression fractures, but there are no systematic review and meta-analysis of its efficacy. Therefore, we will conduct this study to systematically evaluate the clinical effects of external treatment of TCM for patients with constipation after thoracolumbar compression fractures.

Methods:

We will search the following electronic databases: PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infastructure, Chinese Biomedical Literatures Database, Chinese Scientific Journal Database, and Wanfang Database. Randomized controlled trials on the treatment of constipation after thoracolumbar compression fractures with external treatment of TCM published from inception to May 2021 will be included in the search scope. The observation group was treated with Simple external treatment of TCM (such as external application of Chinese medicine, Chinese drugs at the acupoint, acupuncture, moxibustion, etc) or external treatment of TCM combined with conventional treatment/nursing of Western medicine, while the control group only was treated by conventional treatment/nursing of Western medicine. After screening literatures, extracting data, and assessing the risk of bias in the included studies, meta-analysis will be performed by Revman 5.3 software.

Results:

This study is expected to provide an evidence of the efficacy of external treatment of TCM for constipation after thoracolumbar compression fractures.

Conclusion:

The results of this meta-analysis may help provide evidence to determine whether external treatment of TCM can be effective interventions for thoracolumbar compression fractures patients with constipation.

Efficacy and safety of PD-1/PD-L1 inhibitors combined with CTLA-4 inhibitor versus chemotherapy for advanced lung cancer
Authors: Zhang Pei-Pei , Wang Juan , Ding Da-Zhi , Zhang Li , Cheng Chun , Chen Da-Ke
Published: September 2021

Background:

This meta-analysis was performed to compare efficacy and tolerability between antiprogrammed cell death (PD-1)/programmed cell death-ligand-1 (PD-L1) + anticytotoxic T-lymphocyte-associated protein-4 (CTLA-4) treatment and chemotherapy in advanced lung cancer.

Methods:

Cochrane Library, Embase, and PubMed databases were searched for potential articles. The fixed-effect model or random-effect model was adopted for pooled analysis based on the I2 and P-value.

Results:

Six articles with 1338 patients were identified and subjected to meta-analysis. Compared with chemotherapy, anti-PD-1/PD-L1 + anti-CTLA-4 treatment could significantly improve the overall survival (hazard ratio [HR] = 0.78, 95%confidence interval [CI]: 0.71–0.84, P = .21) and progression-free survival (HR = 0.77, 95%CI: 0.71–0.83, P = .30) of advanced lung cancer patients. Moreover, there was no obvious difference in the incidence of 3 to 4 adverse events (AEs) serious adverse reactions (HR = 1.35, 95%CI: 0.66–2.74, P < .00001) between the 2 treatment groups, but the incidence rates of AEs leading to discontinuation (HR = 2.56, 95%CI: 1.53–4.30, P < .00001) and AEs leading to death (HR = 2.10, 95%CI: 1.21–3.63, P = .20) were higher. Furthermore, no remarkable differences in objective response rate (HR = 1.31, 95%CI: 0.97–1.77, P = .02) were observed between the 2 groups.

Conclusion:

Our meta-analysis revealed that PD-1/PD-L1 inhibitors plus CTLA-4 inhibitor could markedly improve the endpoint outcomes of patients compared with chemotherapy alone, and did not significantly increase the serious adverse reactions. Thus, it can serve as a new treatment strategy for advanced lung cancer.

Published: September 2021

We aimed to investigate the genetic and demographic differences and interactions between areas where observed genomic variations in Mycobacterium tuberculosis (M. tb) were distributed uniformly in cold and hot spots.

The cold and hot spot areas were identified using the reported incidence of TB over the previous 5 years. Whole genome sequencing was performed on 291 M. tb isolates between January and June 2018. Analysis of molecular variance and a multifactor dimensionality reduction (MDR) model was applied to test gene-gene-environment interactions. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were computed to test the extent to which genetic mutation affects the TB epidemic using a multivariate logistic regression model.

The percentage of the Beijing family strain in hot spots was significantly higher than that in cold spots (64.63% vs 50.69%, P = .022), among the elderly, people with a low BMI, and those having a history of contact with a TB patient (all P < .05). Individuals from cold spot areas had a higher frequency of out-of-town traveling (P < .05). The mutation of Rv1186c, Rv3900c, Rv1508c, Rv0210, and an Intergenic Region (SNP site: 3847237) showed a significant difference between cold and hot spots. (P < .001). The MDR model displayed a clear negative interaction effect of age groups with BMI (interaction entropy: −3.55%) and mutation of Rv0210 (interaction entropy: −2.39%). Through the mutations of Rv0210 and BMI had a low independent effect (interaction entropy: −1.46%).

Our data suggests a statistically significant role of age, BMI and the polymorphisms of Rv0210 genes in the transmission and development of M. tb. The results provide clues for the study of susceptibility genes of M. tb in different populations. The characteristic strains showed a local epidemic. Strengthening genotype monitoring of strains in various regions can be used as an early warning signal of epidemic spillover.
Airway management during left-sided gastrobronchial fistula repair after esophagectomy for esophageal carcinoma
Authors: Wang Sih-Yu , Yuan Wei-Chin , Wu En-Bo
Published: September 2021

Rationale:

Gastrobronchial fistula (GBF) is a rare but life-threatening complication of esophagectomy with gastric conduit reconstruction, and airway management during fistula repair is challenging. Here, we describe airway management in a patient undergoing left-sided GBF repair using video-assisted thoracoscopic surgery.

Patient concerns:

A 63-year-old man diagnosed with esophageal carcinoma underwent esophagectomy with reconstruction by gastric pull-up and tabularization of the gastric conduit. Subsequently, about 8 weeks later, the patient presented with repeated pneumonia and a 1-week history of cough with significant sputum, dysphagia, and repeated fever.

Diagnosis:

GBF, a rare postoperative complication, was located on the left main bronchus at 2 cm below the carina and was diagnosed based on findings from gastroscopy, flexible bronchoscopy, and thoracic computed tomography scan with contrast.

Interventions:

We performed left-sided one-lung ventilation (OLV) under total intravenous anesthesia instead of inhalational anesthetics. The left-sided OLV, with positive end-expiratory pressure (PEEP) and nasogastric tube decompression, generated positive pressure across the fistula. It prevented backflow into the left main bronchus. Total intravenous anesthesia preserved hypoxic pulmonary vasoconstriction and prevented adverse effects associated with inhalational anesthetics. A right-sided, double-lumen endotracheal tube was inserted after anesthesia induction, and surgical repair was performed through a right-sided video-assisted thoracoscopic surgery.

Outcomes:

Intraoperative hemodynamics remained relatively stable, except for brief tachycardia at 113 beats/min. Arterial blood gas analysis revealed pH 7.17 and PaO2 89.1 mmHg upon 100% oxygenation, along with hypercapnia (PaCO2 77.1 mmHg), indicating respiratory acidosis. During OLV, pulse oximetry remained higher than 92%. The defect in the left main bronchus was successfully sutured after dissecting the fistula between the left main bronchus and the gastric conduit, and subsequently, OLV resulted in ideal ventilation.

Lessons:

A left-sided GBF could lead to leakage from the OLV during surgery. Possible aspiration or alveolar hypoventilation due to this leakage is a major concern during airway management before surgical repair of the main bronchus.
Carrelizumab combined with anlotinib in the treatment of extensive-stage small cell lung cancer
Authors: Liu Liang , Zhang Xin , Zhou Lihua , Yang Tao , Qiao Yun , Jiang Xiaodong
Published: September 2021

Rationale:

The emergence of immune checkpoint inhibitors has brought new breakthroughs in the treatment of small cell lung cancer (SCLC). Programmed cell death-ligand 1 inhibitors combined with chemotherapy have been approved for the first-line treatment of extensive-stage small cell lung cancer (ES-SCLC). However, programmed death 1 inhibitors have limited efficacy in the treatment of SCLC. The reason may be related to the abnormal vascular state in the tumor microenvironment.

Patient concerns:

A 55-year-old male patient, presenting cough and sputum for 1 month.

Diagnoses:

The patient was clinically diagnosed with SCLC and staged as ES-SCLC.

Interventions:

Etoposide combined with lobaplatin treatment every 3 weeks for 4 cycles, evaluate as progressive disease. On the basis of the original plan, combined with camrelizumab for 2 cycles, evaluation as progressive disease. Then, the patient was treated with intravenous infusion of camrelizumab plus oral anlotinib. After 4 cycles, evaluation as partial response. Then we continued to use camrelizumab combined with anlotinib treatment for the patient. At the end of 26 cycles, the chest computed tomography examination revealed that the patient had achieved complete remission.

Outcomes:

After treated with carrelizumab combined with anlotinib for 26 cycles, the curative effect was evaluated as complete remission, progression-free survival was 24 months and there was no immune-related adverse reaction during treatment period. Besides, the patient developed complicated hand–foot syndrome, but this symptom was significantly relieved after reducing the dosage of anlotinib.

Lessons:

In this case, antiangiogenesis combined with programmed death 1 inhibitors significantly inhibited tumor progression. It also indicated that anlotinib concurrent carrelizumab may be a superior choice for ES-SCLC. Further clinical trials required to confifirm its effificacy and safety.
Home-based rehabilitation programs on postural balance, walking, and quality of life in patients with stroke
Authors: Lim Jae-Heon , Lee Hye-Sun , Song Chiang-Soon
Published: September 2021

Background

The most challenging aspect of rehabilitation is the high costs of in-patient rehabilitation programs and poor continuity of care while patients are transferred to home. In this regard, numerous home-based rehabilitation programs have been developed. The purpose of this study was to investigate the effects of home-based rehabilitative programs on postural balance, walking, and quality of life in individuals with chronic hemiparetic stroke.

Design

A CONSORT-compliant randomized controlled trial.

Methods

Seventeen community-dwelling people diagnosed with a first stroke participated in this study. They randomly divided the home-based rehabilitative program (HBP) group (n = 9) and control group (n = 8). The HBP group received coordination exercises at home and the control group received clinic-based exercises. This study measured postural balance, walking, and quality of life using four outcome measures: 10-meter walk test, figure of 8 walk test, four-square step test, and 36 item short-form survey.

Results

After analysis, it was found that the HBP improved postural balance, comfortable speed, and fast speed walking, and straight and curved walking for chronic stroke. Second, clinic-based rehabilitation services improved postural balance, comfortable speed, and fast speed walking abilities in patients with chronic stroke.

Conclusion

The results of this study suggest that the HBP group received positive benefits with regard to the postural balance and walking abilities of chronic hemiparetic stroke patients compared to the clinical setting exercise program.
A meta-analysis of the association of atrial septal abnormalities and atrial vulnerability
Authors: Sun Heng , Zhou Chang , Xu Liang , Xu Tao
Published: September 2021

Background:

The mechanism of cryptogenic stroke (CS) in patients with atrial septal abnormalities remains unclear, and the increased incidence of atrial vulnerability may be one of the reasons. We performed this meta-analysis to clarify the association between atrial septal abnormalities and atrial vulnerability, and to provide evidence-based basis for the prevention and mechanism of CS.

Methods:

We systematically searched for studies on the association between atrial septal abnormalities and atrial vulnerability, and pooled available data on types of atrial septal abnormalities, types of atrial vulnerability, and methods of atrial vulnerability detection. The primary endpoints were the occurrence of atrial arrhythmias or P wave abnormalities. Random-effects models were used to calculate odds ratios (OR) and 95% confidence intervals (CI).

Results:

Twelve case-control studies were eligible. Compared with the control group, patients with atrial septal abnormalities had a higher risk of atrial vulnerability (OR: 1.93; 95% CI: 1.13-3.30, P = .02). Data based on stroke patients showed that the group with atrial septal abnormalities had a higher risk of atrial vulnerability than the control group (OR: 2.00; 95% CI: 1.13–3.53, P = .02). However, there was no significant difference in the incidence of atrial vulnerability between the 2 groups of nonstroke patients. Subgroup analysis showed that although atrial septal abnormality increased the risk of atrial vulnerability in the subgroup of atrial septal aneurysm (OR: 1.68; 95% CI: 0.47–5.95, P = .42), the subgroup of atrial fibrillation (AF)/atrial fluster (OR: 1.81; 95% CI: 0.94–3.46, P = .07) and the subgroup of subcutaneous recording system (OR: 1.33; 95% CI: 0.68–2.61, P = .41), the difference was not statistically significant.

Conclusions:

Atrial septal abnormalities can increase the risk of atrial vulnerability, and atrial arrhythmia caused by atrial septal abnormalities may be one of the mechanisms of CS.
Coronavirus disease 2019 pandemic, restriction, and orthopedic trauma
Authors: Toy Serdar , Polat Oktay , Özbay Hakan
Published: September 2021

In 2019, the Coronavirus disease 2019 (Covid-19) was reported in Wuhan, China. Governments in various countries had taken many safeguards. This study investigated the incidence of orthopedic trauma in a rural region epidemiologically and guided source distribution and medical professionals to sustain healthcare systems.

Between December 2019 and August 2020, 1651 patients admitted to orthopedics and traumatology clinics with trauma were evaluated in this study. Patients were grouped into 3 groups: pre-covid, restriction, and permitted groups. Age, sex, and fracture types of patients were recorded.

The number of patients in the pre-covid period was 629 (38.1%), those were 334 (20.2%) in the restriction period, and 688 (41.7%) patients were admitted in the permitted period. A total of 1203 (72.9%) patients with upper extremity fractures, 383 (23.2%) patients with lower extremity fractures, and 65 (3.9%) patients with axial skeleton and pelvic ring fractures were included in the study. The lowest rates were found in the restriction period when all fractures were evaluated according to the admission periods. There were significant differences between admission dates and the fractures (P < .001).

In this study, a decrease in orthopedic trauma rates was observed by half in the restriction period compared with the other 2 periods. Public health precautions had led to a reduction in the incidence of orthopedic trauma in all age groups.
The effects of additional electrical stimulation combined with repetitive transcranial magnetic stimulation and motor imagery on upper extremity motor recovery in the subacute period after stroke
Authors: Kang Ji Hye , Kim Min-Wook , Park Kyoung Ha , Choi Young-Ah
Published: September 2021

Background:

To evaluate the therapeutic effects of additional electrical stimulation (ES) combined with low frequency (LF)-repetitive transcranial magnetic stimulation (rTMS) and motor imagery (MI) training on upper extremity (UE) motor function following stroke.

Methods:

The participants with subacute stroke in the experimental group (n = 8) received LF rTMS + MI + active ES interventions, and those in control group (n = 9) received LF rTMS + MI + sham ES interventions. Interventions were performed 5 days a week for 2 weeks, for a total of 10 sessions. All participants were given the same dosage of conventional rehabilitation during the study period. The primary outcome measure was the UE Fugl-Meyer Assessment (FMA). The secondary outcome measures were the shoulder abduction and finger extension scores, modified Barthel Index, Purdue Pegboard Test, and finger tapping test. All scores were measured before and just after the intervention.

Results:

After the 2-week intervention period, the FMA and modified Barthel Index scores were improved in both groups compared to baseline assessment (P < .001 in the experimental group and P = .008 in the control group). Of note, the change in FMA scores was significantly higher in the experimental group compared with that of the control group (P = .04).

Conclusion:

These results suggest that the use of LF rTMS + MI combined with additional ES lead to greater improvement of UE motor function after stroke. As such, this intervention may be a promising adjuvant therapy in UE motor training.

Published: September 2021

Background:

Candidemia and Candida-associated catheter-related bloodstream infections (CRBSIs) are the significant cause of mortality and morbidity in patients with malignancy.

Methods:

A retrospective analysis including all pediatric hematologic/oncologic malignancies patients with CRBSIs treated in Dr. Behçet Uz Children Diseases and Surgery Training and Research Hospital between the period of 2009 and 2020.

Results:

During the study period, 53 children with CRBSIs associated with Candida species were included. The most common malignancy was acute lymphoblastic leukemia (45.3%) and acute myeloid leukemia (15.1%). A total of 56 Candida isolates were present including non–albicans Candida species (80.4%) and Candida albicans (19.6%). The most common isolated Candida species was Candida parapsilosis (42.9%) and followed by C. albicans (19.6%). The ratio of azole prophylaxis was significantly higher in patients with the non–albicans Candida group (P=0.031). Candida-related endocarditis (vegetation) was present in 2 (3.8%) patients, and the overall rate of hepatosplenic candidiasis was 3.8%. Seven days Candida attributable mortality was 7.5% (4 patients) and 30 days Candida attributable mortality was 11.3% (6 patients). The Candida species responsible for the Candida-related deaths were as following: Candida tropicalis (n=3), C. parapsilosis (n=2), and C. lusitanae (n=1).

Conclusion:

In pediatric cancer patients with Candida-associated CRBSIs, evaluation of the patient for organ involvement including liver and spleen ultrasonography and cardiac involvement with echocardiography are essential regardless of the patients’ clinical picture.

Authors: Hermann Erin , Ferdjallah Asmaa
Published: September 2021

Eltrombopag is approved for the treatment of chronic immune thrombocytopenia purpura (ITP) in pediatric patients 1 year and older who have demonstrated an insufficient response to corticosteroids and intravenous immunoglobulin. We present the case of a 2-year-old boy with chronic immune thrombocytopenia purpura who developed life-threatening adverse effects of acute liver failure, metabolic acidosis and encephalopathy with standard drug dosing. To our knowledge, this is the first case of eltrombopag-induced hepatic encephalopathy highlighting the critical need for prescribers to exercise caution when prescribing eltrombopag in the pediatric setting.

Authors: Shaukat Zunaira , Shaheen Najma , Abubakar Muhammad , Wali Rabia
Published: September 2021

Objectives:

The aim was to review outcome with residual disease at the end of first line chemotherapy in patients with extracranial germ cell tumor (GCT) in our resource limited setting.

Methods:

A retrospective analysis of 196 patients with GCT recruited at Shaukat Khanum Memorial Cancer Hospital (SKMCH) from January 2008 to December 2016. Data fields included site, histopathology, stage, risk groups, baseline alpha fetoprotein, beta human chorionic gonadotropin levels, residuum after primary treatment, completeness of surgical excision and outcomes. Data analysis involved quantitative analysis, mean and median calculations, event free survival (EFS) and overall survival (OS) calculations using Kaplan-Meier curves.

Results:

In 196 included patients, M:F ratio was 1. There were 81 (41.3%) adolescents. Alpha fetoprotein was >10,000 IU/L in 56 (28.6%) patients. Sixty-two (31.6%) patients had extragonadal disease. Most patients (n=137, 69.9%) presented with advanced stage (III/IV). Seventy-six patients had postchemotherapy residual disease (n=59 [78%] with partial response (PR) and 17 [22%] with no response [NR]). Five-year OS was 83% and EFS was 67%. Five-year EFS of patients with complete remission after primary chemotherapy was 85% versus 70% in patients with PR and 6% in those with NR (P=0.001). OS in patients with complete remission, PR and NR was 94%, 87%, and 46%, respectively. All patients with NR progressed or relapsed and 8/17 died. Four patients with normalized tumor marker response were found to have active tumor on resection of postchemotherapy residuum.

Conclusion:

Patients with postchemotherapy residual disease in pediatric extracranial GCTs, fare better if their residuum is resected compared with those who do not undergo resection.
Oncology Nursing Telephone Triage Workshop
Authors: Ciccolini Kathryn , Spaulding Erin M. , Boyde Tiffini , Berizzi Donna , Hansen Bryan R.
Published: September 2021

Background

Outpatient oncology nurses are responsible for symptom assessment/management and care coordination during telephone triage. Nursing telephone triage interventions can improve patient outcomes and clinical efficiency. Therefore, the lack of education and training in telephone triage can greatly impact patient care.

Objective

Using a prospective pretest/posttest design, we sought to determine if a telephone triage educational workshop would improve oncology nurses’ knowledge, confidence, and skill over 12 weeks.

Intervention/Methods

The educational intervention incorporated an online didactic lecture, group case scenario, and feedback on a virtual triage simulation. Evaluation was conducted before and after the intervention through an online, 13-item survey (knowledge and confidence) and simulation utilizing a 56-item checklist (skills).

Results

Thirteen oncology nurses were enrolled; 54% did not have telephone triage experience before this job. A total of 12 participants completed the workshop. From pretest to posttest, there was a median 1.0 out of 5.0 (interquartile range, 2.8) improvement in confidence (P = .008) and a 26.3% (interquartile range, 15.2) improvement in skills (P = .002). There was no difference in knowledge scores from pretest to posttest (P = .11).

Conclusions

This workshop was associated with an improvement in oncology nurse confidence and skill, using telephone triage models. It benefits an existing process within the outpatient center and it highlights a new educational strategy that may optimize nursing practice and improve patient care and experience.

Implications for Practice

This workshop contributes to existing evidence of telephone triage models and nursing education. The findings can guide future research, nursing orientation, and educational activities within the field of nursing and telehealth.
Relationship Between Anticipatory Grief and Communication Avoidance in Chinese Caregivers of Patients With Advanced Cancer
Authors: Yu Wenhua , Lu Qian , Lu Yuhan , Guo Renxiu , Hou Xiaoting , Yang Hong
Published: September 2021

Background

Anticipatory grief (AG) and its relationship with communication avoidance in Chinese caregivers of patients with advanced cancer have not been previously examined. An association between AG and communication avoidance could provide important insights to Chinese caregivers worthwhile to be investigated.

Objectives

The aims of this study were to evaluate AG and communication avoidance with patients among Chinese caregivers of patients with advanced cancer and to identify their relationship.

Methods

A cross-sectional study was conducted with a convenience sample of caregivers of patients with advanced cancer practicing at an academic cancer hospital. The participants completed the Anticipatory Grief Scale (AGS) and the Caregivers’ Communication With Patients About Illness and Death scale.

Results

Of the 256 participants, the mean age was 49.10 (SD, 12.87) years, and 63.28% of participants were female. The mean AGS score was 88.05 (SD, 18.42). The AGS subscales in descending order of scores were feeling of loss, sadness, decreased ability to function at usual tasks, anxiety, anger, guilt, and irritability. The mean Caregivers’ Communication With Patients About Illness and Death score was 3.60 (SD, 1.13). In the multiple linear regression, AG severity was significantly, positively correlated with communication avoidance. Old age, low education level, religious belief, low income, and living with the patient, spouse, parents, and child implied severe AG.

Conclusions

Chinese caregivers of patients with advanced cancer reported a high AG and poor communication with patients about illness and death. Less communication was related to more severe AG.

Implications for Practice

Healthcare professionals should pay attention to AG severity and communication of caregivers of patients with advanced cancer to explore the suitable clinical intervention.
Effect of Urea Cream on Hand-Foot Syndrome in Patients Receiving Chemotherapy
Authors: Lan Tzu-Chen , Tsou Po-Han , Tam Ka-Wai , Huang Tsai-Wei
Published: September 2021

Background

Hand-foot syndrome (HFS) is a specific adverse effect of certain chemotherapy that may lead to dosage reduction or chemotherapy discontinuation in patients with cancer. Topical urea cream may reduce symptom severity in patients with HFS. However, these studies have not provided consonant results.

Objective

To determine the effectiveness of urea cream, we conducted a meta-analysis of clinical trials to evaluate the prevention and treatment of HFS.

Methods

PubMed, EMBASE, and Cochrane Library databases were searched for studies published before September 2020. The study registered at PROSPERO (CRD 42020203164). Incidence of HFS reported in studies at any grade and at second grade or greater was assessed within 3 to 12 weeks. Secondary outcomes were time to HFS, incidence of skin-related adverse events, chemotherapy dose reduction, and quality of life.

Results

Seven trials involving 1387 patients were reviewed. In the prophylactic subgroup, patients with urea cream intervention showed a significantly lower incidence of HFS at second grade or greater (risk ratio, 0.72; 95% confidence interval, 0.58-0.90) and a nonsignificant lower incidence of any-grade HFS (risk ratio, 0.79; 95% confidence interval, 0.58-1.08) than those not receiving urea cream intervention.

Conclusions

Urea cream has advantages to reduce the incidence of severe HFS.

Implications for Practice

Urea cream is a safe and viable topical prevention strategy that can reduce the incidence of high-grade HFS in patients undergoing chemotherapy. We recommend a routine treatment option before chemotherapy for the patients.

Published: September 2021

Background:

Nursing faculty members may need several mentors to succeed in scholarly productivity, career development, work-life balance, and socialization in the academy. Underrepresented (UR) faculty report additional challenges to success.

Purpose:

The aim of this study was to search the literature for best practices in mentoring UR faculty.

Methods:

An integrative review was conducted to identify best and evidence-based practices for mentoring UR faculty, including gender, sexual minority, race, ethnicity, and geographic remoteness (rural). Fifteen articles were rated on evidence and methodological quality.

Results:

Successful mentorship programs include honest communication, including all stakeholders in forming a mentoring program, goals and activities that come from the mentees, and guaranteed resources.

Conclusions:

Underrepresented nursing faculty may benefit from formal mentoring programs, but more research is needed.
Thermoregulatory responses in persons with lower-limb amputation during upper-limb endurance exercise in a hot and humid environment
Authors: Fukuhara Kouki , Mikami Yukio , Hasegawa Hiroshi , Nakashima Daigo , Ikuta Yasunari , Tajima Fumihiro , Kimura Hiroaki , Adachi Nobuo
Published: September 2021

Background:

Persons with an amputation may have an increased heat strain due to reduced surface area. However, there is limited evidence on the thermoregulatory responses in persons with lower-limb amputation (LLA). Although a previous study reported no difference in their rectal temperatures (Tres) in a hot environment, suggesting compensatory sweating of the intact limb, we examined the thermoregulatory responses of such persons in a hot and humid environment.

Objective:

To compare the thermoregulatory responses―through changes in Tre, sweat, and oxygen uptake (O2)―between persons with LLA and able-bodied (AB) individuals, in hot and humid environments.

Study design:

A nonrandomized control trial.

Methods:

Nine AB men (AB group) and nine persons with LLA group performed the arm ergometer exercise at 60% peak power output intensity for 60 min in a hot and humid environment, and they were tested before and after performing. The O2, Tre and skin temperature, and total body sweating, and local sweating during exercise were measured and compared between the groups.

Results:

The changes in O2 and Tre after the endurance exercise did not differ between the groups (ΔTre: AB group, 1.1°C ± 0.5°C; LLA group, 1.2°C ±0.3 °C; P = 0.65), whereas the amount of local sweating of the chest (group effect, P < 0.01 by two-way analysis of variance [group × time], the group effect size was medium, η2 = 0.10) and dehydration rate (AB group, 1.5% ± 0.5%; LLA group, 2.1% ± 0.5%; P = 0.03) were higher in the LLA than in the AB group.

Conclusions:

We compared the thermoregulatory responses of persons with LLA with those of AB individuals in hot and humid environments. Core body temperatures of persons with LLAs during endurance exercise were not different from those of AB men even in hot and humid environments. We found compensatory increases in the sweat rate of the chest and increased dehydration rate in persons with LLA. More sweat potentially means that athletes with LLA need to drink more fulids.
