Published: January 2020

Abstract

Background:
Coronary heart disease angina pectoris is a common clinical symptom in patients with coronary heart disease, due to coronary atherosclerotic stenosis or sputum leading to coronary insufficiency, myocardial transient ischemia, hypoxia caused by precordial pain as the main clinical manifestations Group syndrome. Coronary heart disease angina causes coronary blood flow insufficiency, cannot meet the normal activities of myocardial cells, leading to myocardial ischemia or necrosis. When the disease occurs, there is paroxysmal and crushing pain in the precordial area of the patient. Therefore, we recognize the importance of the disease and have paid enough attention. Clinical studies in recent years have found that the use of acupuncture in the treatment of angina pectoris has a good clinical application prospect. This study was conducted to study the effect of using acupuncture to treat angina pectoris.

Methods and analysis:
We will search for PubMed, Cochrane Library, AMED, EMbase, WorldSciNet, Nature, Science online and China Journal Full-text Database, China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to November 2019. We will use the criteria provided by Cochrane 5.1.0 for quality assessment and risk assessment of the included studies, and use the Revman 5.3 and Stata13.0 software for meta-analysis of the effectiveness, recurrence rate, and symptom scores of angina pectoris.

Ethics and dissemination:
This systematic review will evaluate the efficacy and safety of acupuncture for angina pectoris. Because all of the data used in this systematic review and meta-analysis have been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial.

Abstract

Introduction:
Anastomotic leakage (AL) remains one of the most threatening complications in colorectal surgery with the incidence of up to 20%. The aim of the study is to evaluate the safety and feasibility of novel – trimodal intraoperative colorectal anastomosis testing technique.

Methods and analysis:
This multi-center prospective cohort pilot study will include patients undergoing colorectal anastomosis formation below 15 cm from the anal verge. Trimodal anastomosis testing will include testing for blood supply by ICG fluorescence trans-abdominally and trans-anally, testing of mechanical integrity of anastomosis by air-leak and methylene blue leak tests and testing for tension. The primary outcome of the study will be AL rate at day 60. The secondary outcomes will include: the frequency of changed location of bowel resection; ileostomy rate; the rate of intraoperative AL; time, taken to perform trimodal anastomosis testing; postoperative morbidity and mortality; quality of life.

Discussion:
Trimodal testing of colorectal anastomosis may be a novel and comprehensive way to investigate colorectal anastomosis and to reveal insufficient blood supply and integrity defects intraoperatively. Thus, prevention of these two most common causes of AL may lead to decreased rate of leakage.

Chronic chorioretinal detachment under normal intraocular pressure in eye with uveitic glaucoma after trabeculectomy
Authors: Sakurai Yutaka , Takayama Kei , Abe Tatsuhiro , Takeuchi Masaru 
Published: January 2020

Abstract

Rationale:
Choroidal detachment is a major postoperative complication of trabeculectomy. Postoperative choroidal detachment occurs with low intraocular pressure (IOP), and is naturally resolved by elevation of IOP. We report a case of chronic chorioretinal detachment (CRD) in the eye with uveitic glaucoma after trabeculectomy which persisted with normal IOP resistant for medication and required surgery.

Patient concerns:
A 63-year-old man was referred to our department with uncontrolled uveitic glaucoma in his right eye. At first presentation, IOP was 62 mm Hg in the right eye with opened angle, and active ocular inflammation was presented by moderate cell infiltration to the anterior chamber.

Diagnosis:
Uveitic glaucoma.

Interventions:
Trabeculectomy with mitomycin-C combined with phacoemulsification were performed without any surgical trouble. Postoperative inflammation in the anterior segment was mild, and IOP decreased to the middle-teen.

Outcomes:
At 19 days after surgery, the depth of the anterior chamber changed to shallow and CRD occurred in the inferior quadrant area. This complication could not be resolved by additional systemic corticosteroid medication and scleral fenestration. Although IOP was maintained in middle-teen range, suture fixation of the sclera flap and additional scleral fenestration were necessary to resolve CRD at 191 days after primary surgery.

Lessons:
In uveitic eye with uncontrolled ocular hypertension, severe CRD after trabeculectomy is able to occur even with normal IOP, which requires surgical procedure in addition to the medical treatment.
FLAIR vascular hyperintensity-DWI mismatch most likely to benefit from recanalization and good outcome after stroke
Authors: Wang Yong , Zhou Zhijun , Ding Shaohua 
Published: January 2020

Abstract
We assessed the value of fluid-attenuated inversion recovery vascular hyperintensity (FVH)-diffusion-weighted imaging (DWI) mismatch in predicting revascularization and functional outcome in stroke patients with large vessel occlusion (LVO) after endovascular thrombectomy (EVT).
Seventy-two acute stroke patients within 6 hour of stroke onset who received EVT were enrolled. FVH-DWI mismatch, revascularization (mTICI score), functional outcome (mRS at 3 months) and other clinical data were collected. Statistical analysis was performed to predict revascularization and functional outcome after stroke.
Twenty-nine patients (60.42%) had FVH-DWI mismatch in patients with complete revascularization and 8 patients (33.33%) had FVH-DWI mismatch in patients with no/partial revascularization, and there was significant difference in 2 groups (t = 4.698; P = .045). The good functional outcome group (37/72; 51.39%) had higher FVH score (4.38 ± 1.53 vs 3.49 ± 1.52; t = 2.478; P = .016), higher FVH-DWI mismatch ratio (81.25% vs 48.15%; t = 10.862; P = .002), higher complete revascularization ratio (83.78% vs 48.57%; t = 10.036; P = .002) than the poor functional outcome group (35/72; 48.61%). Spearman's rank correlation analysis revealed that FVH-DWI mismatch was positively correlated with complete revascularization (r = 0.255; P = .030) and good functional outcome (r = 0.417; P = .000). Multivariable logistic regression analysis demonstrated that FVH-DWI mismatch was independently associated with complete revascularization (OR, 0.328; 95% CI, 0.117–0.915; P = .033) and good functional outcome (OR, 0.169; 95% CI, 0.061–0.468; P = .001).
Assessments of FVH-DWI mismatch before thrombectomy therapy might be useful for predicting revascularization and functional outcome in stroke patients with LVO.
Correlation between expression of Ki-67 and MSCT signs in different types of lung adenocarcinoma

Published: January 2020

Abstract
To investigate the correlation between the proliferating cell nuclear antigen Ki-67 and the multislice computed tomography (MSCT) signs in different subtypes of lung adenocarcinoma.
Ninety-five patients with lung adenocarcinoma confirmed by surgical pathology and treated between January 2017 and December 2017 were included. MSCT was performed before the operation, and the characteristics of the high-resolution CT (HRCT) signs of the lesions were compared with the Ki-67 immunohistochemistry results.
The levels of Ki-67 in the 95 lung adenocarcinoma specimens were positively correlated with the malignancy of lung adenocarcinoma. Spearman correlation coefficient was 0.615. The expression of Ki-67 was positively correlated with the nodules’ diameter, density, and lobulated sign, with Spearman correlation coefficients of 0.58, 0.554, and 0.436. There was no significant correlation with spiculation and pleural retraction, with correlation coefficients of 0.319/0.381.
These findings suggest that the MSCT signs of different types of lung adenocarcinoma might be associated with the expression of Ki-67. Without replacing biopsy, the imaging features of pulmonary nodules could be comprehensively analyzed to evaluate the proliferation potential of preoperative nodules, but additional studies are needed for confirmation.

Published: January 2020

Abstract

Background:
Delirium is a commonly occurred complication in the critically ill. Melatonin is an endogenous hormone exerting multiple biological effects, mainly in regulating diurnal rhythms, also in inflammatory process and immune response. We aimed to assess the efficacy of exogenous melatonergics in prevention of delirium.

Methods:
PubMed, Cochrane Library, and Embase will be searched to identify randomized controlled trials published from 1960 to April 2019. Critically ill adult patients administrated with melatonergics will be included. The primary outcome measure will be the incidence of delirium. The secondary outcome measure will be the length of stay in intensive care unit. The pooled effects of dichotomous outcomes will be analyzed as risk ratio, and that of continuous outcomes will be analyzed using weighted mean difference. Subgroup and sensitivity analyses will be conducted. Funnel plots and/or Egger test will be done for the examination of publication bias. The quality of evidence resulting from this study will be evaluated using the GRADE methodology. Trial sequential analysis (TSA) will be done to test whether the evidence in our meta-analysis is reliable and conclusive.

Result:
The evidence to date of the melatonergics in prevention of delirium will be systematically reviewed and meta-analyzed with the GRADE level reported and TSA examined.

Conclusion:
The stronger evidence for the efficacy of melatonergics in prevention of delirium in critically ill patients will be provided for intensive care physicians.

Autoimmune hemolytic anemia in hospitalized patients
Authors: Chen Chunxia , Wang Lixin , Han Bing , Qin Li , Ying Binwu 
Published: January 2020

Abstract
Autoimmune hemolytic anemia (AIHA) is a rare disease in which autoantibodies target red blood cells (RBCs), leading to anemia that ranges from no symptoms to severe life-threatening hemolysis. Little is known about the severity of anemia, blood transfusion efficiency and risk of transfusion-related reactions among hospitalized AIHA patients, especially in those with incompatible RBC transfusions.
A retrospective study was conducted among hospitalized AIHA patients from January 2009 to December 2015 in a large tertiary care medical center in southwest China.
A total of 450 AIHA hospitalized patients were recruited, of whom 97.3% had warm AIHA, 30.3% had primary AIHA, and 90.7% were treated with corticosteroids. On admission, approximately 3% of patients had an hemoglobin (Hb) <30 g/L, 34% had an Hb between 30 and 59.9 g/L, and 46% had an Hb ranging from 60 to 89.9 g/L. A total of 2509.5 U RBCs were transfused to AIHA patients, and 14 transfusion-related adverse reactions were recorded, without any hemolytic transfusion reactions. With an average transfusion trigger of 52.0 ± 9.3 g/L, 59.7% of the patients received RBCs, and 55.8% of the transfusions were viewed as effective. Least incompatible RBCs were given in 39% of the transfusions, but the transfusion efficiency did not significantly decrease with these incompatible blood transfusions (P = .253). Primary AIHA patients with a nadir Hb of approximately 40 to 50 g/L during their hospital stay had the highest rate of remission and did not require a different total number of RBC transfusions (P = .068) or length of hospitalization (P = .194) compared to other groups with nadir Hb values <30 g/L, ≥30 and <40 g/L, ≥50 and <60 g/L, and ≥60 g/L.
One-third of AIHA patients suffered from severe anemia during hospitalization, and transfusions, even with incompatible RBCs, were safe and efficient. However, transfusion triggers between 40 and 50 g/L seemed to benefit the most patients by alleviating the RBC destruction caused by autoantibodies, and a restrictive transfusion strategy was beneficial in AIHA patients.
The hepatitis B core antibody positive/hepatitis B surface antigen negative pattern is associated with the increased risk of intracranial atherosclerotic stenosis
Authors: Shen Lin , Zhou Huchuan , Wei Fei , Shuai Jie 
Published: January 2020

Abstract
The high prevalence of hepatitis B virus (HBV) infection and intracranial atherosclerotic stenosis (ICAS) in Asia raises the question as to whether HBV infection is associated with ICAS. To answer this question, we tested the association between HBV infection and ICAS. Totally, 3072 in-hospital subjects were retrospectively enrolled. All subjects underwent computed tomography angiography (CTA) and serological testing for HBV infection. Based on the results of CTA, all subjects were categorized into 4 groups including ICAS, extracranial atherosclerotic stenosis (ECAS), ICAS/ECAS (both ICAS and ECAS), and normal. HBV infection was divided into 4 patterns including hepatitis B core antibody (anti-HBc) positive/hepatitis B surface antigen (HBsAg) positive, anti-HBc-positive/HBsAg-negative, anti-HBc-negative/HBsAg-positive, and anti-HBc-negative/HBsAg-negative. Risk factors for atherosclerosis were collected based on medical records. Multiple logistic regression models were used to determine the association between infection patterns and ICAS. We found that the anti-HBc-positive / HBsAg-negative pattern was associated with the increased risk of ICAS (OR = 1.462) and not associated with ECAS or ICAS / ECAS. The HBc-positive/HBsAg-positive pattern was not associated with ICAS, ECAS or ICAS/ECAS. In conclusions, the anti-HBc-positive/HBsAg-negative pattern was associated with the increased risk of ICAS. Anti-HBc should be employed to investigate the association between HBV infection and cerebrovascular diseases.
Accuracy of Hospital Discharge Codes in Medicare Claims for Knee and Hip Replacement Patients
Authors: Kim Hyunjee , Grunditz Jenny I. , Meath Thomas H.A. , Quiñones Ana R. , Ibrahim Said A. , McConnell K. John 
Published: January 2020

Background:
Despite the importance of the hospital discharge destination field (“discharge code” hereafter) for research and payment reform, its accuracy is not well established.

Objectives:
The aim of this study was to examine the accuracy of discharge codes in Medicare claims.

Data Sources:
2012–2015 Medicare claims of knee and hip replacement patients.

Research Design:
We identified patients’ discharge location in claims and compared it with the discharge code. We also used a mixed-effects logistic regression to examine the association of patient and hospital characteristics with discharge code accuracy.

Results:
Approximately 9% of discharge codes were inaccurate. Long-term care hospital discharge codes had the lowest accuracy rate (41%), followed by acute care transfers (72%), inpatient rehabilitation facility (80%), and home discharges (83%). Most misclassifications occurred within 2 broad groups of postacute care settings: home-based and institutional care. The odds of inaccurate discharge codes were higher for Medicaid-enrolled patients and safety-net and low-volume hospitals.

Conclusions:
Inaccurate hospital discharge coding may have introduced bias in studies relying on these codes (eg, evaluations of Medicare bundled payment models). Inaccuracy was more common among Medicaid-enrolled patients and safety-net and low-volume hospitals, suggesting more potential bias in existing study findings pertaining to these patients and hospitals.
Metabolomics and adductomics of newborn bloodspots to retrospectively assess the early-life exposome
Authors: Petrick Lauren M. , Uppal Karan , Funk William E. 
Published: January 2020

Purpose of review
Exposomics studies can measure health-relevant chemical exposures during a lifetime and estimate the ‘internal’ environment. However, sampling limitations make these features difficult to capture directly during the critical neonatal time period.

Recent findings
We review the use of newborn dried bloodspots (DBS) archived from newborn screening programs for exposomic analysis in epidemiological children's health studies. Emerging ‘omics technologies such as adductomics and metabolomics have been adapted for DBS analysis, and these technologies can now provide valuable etiological information on the complex interplay between exposures, biological response, and population phenotypes.

Summary
Adductomics and metabolomics of DBS can provide robust measurements for retrospective epidemiological investigations. With extensive bioarchiving programs in the United States and other countries, DBS are poised to substantially aid epidemiological studies, particularly for rare and low-frequency childhood diseases and disorders.
Health-related quality of life in renal stone formers: are we improving?
Authors: Serna Juan , Talwar Ruchika , Ziemba Justin B. 
Published: January 2020

Purpose of review
Health-related quality of life (HRQOL) is a multidimensional construct measuring how disease impacts one's life. In the context of nephrolithiasis this is particularly relevant given the active and quiescent phases of the disease which may not correlate with the traditional index of stone free status. Several instruments are now available to objectively measure HRQOL in this population, including the first disease-specific instrument. Therefore, an overview of emerging data on HRQOL is provided that reviews the availability of these tools/instruments and emphasizes patient-centered care and research.

Recent findings
The common generic instruments used to measure HRQOL in any population (36-Item Short Form health survey and Patient-Reported Outcomes Measurement Information System) and the only disease-specific instrument developed to measure HRQOL in nephrolithiasis (Wisconsin Stone Quality of Life Questionnaire) are described. Emerging evidence suggests that age and sex influence renal stone formers perception of their HRQOL across a range of dimensions. Several other factors also appear to play a role, such as socioeconomic status, but these have yet to be validated in more than one study or population, and postoperative outcomes measured in terms of HRQOL are almost absent from the literature.

Summary
Physician-centric outcomes, such as stone status, are no longer the only objective and acceptable measures by which to understand the natural history of nephrolithiasis. Patient-centered approaches through the use of HRQOL are slowly emerging in research and clinical care alike. However, they remain largely in their infancy in these spheres.
Validity Analysis on the Findings of Dehydration in 2 to 24-Month-Old Children With Acute Diarrhea
Authors: Vatandas Nilgun Salk , Yurdakok Kadriye , Yalcin Siddika Songul , Celik Melda 
Published: January 2020

Objective
The most common cause of diarrheal mortality in children is dehydration. In this study, we aimed to assess the validity (sensitivity and specificity) of history and the clinical and laboratory findings in in the diagnosis of dehydration in children younger than 2 years with acute diarrhea.

Methods
One hundred twenty-six 2 to 24-month-old children with acute diarrhea, who were admitted to Hacettepe University Ihsan Dogramaci Children's Hospital's Diarrheal Diseases Treatment and Training Unit, were included. The patients were examined on admission for clinical findings of dehydration. Percent weight loss on admission was calculated by using the weight on admission and the weight after the diarrhea resolution and was used as the golden standard for analyzing the validity of clinical and laboratory findings.

Results
Compared with the golden standard, dehydration was overestimated in 13% of the cases and underestimated in 7% when using only the World Health Organization criteria. Dehydrated children had higher diarrheal frequency and longer anuria time. Thirst, weakness, sunken fontanelle, sunken eyes, decreased tears, dry mucous membranes, and dry lip were detected in children with 2% or greater of weight loss. The most valid laboratory findings were low serum pH (<7.30), low bicarbonate (<15 mmol/L), and hyperurisemia (>5.8 mg/dL). In multivariate analysis, physical findings, such as thirst, dry mucous membranes, weakness, sunken eyes, hoarse crying, and low pH, were found to be significant for the diagnosis of dehydration.

Conclusions
In children with acute diarrhea, diarrheal frequency and last urination time should be asked, thirst, dry mucous membranes, weakness, sunken eyes, and hoarse crying should be examined.
Persistent genital arousal disorder: a special sense neuropathy
Authors: Oaklander Anne Louise , Sharma Saurabh , Kessler Katie , Price Bruce H. 
Published: January 2020

Abstract

Introduction:
Persistent genital arousal (PGAD) is a syndrome of unprovoked sexual arousal/orgasm of uncertain cause primarily reported in female patients. Most patients are referred for mental-health treatment, but as research suggests associations with neurological symptoms and conditions, there is need to analyze cases comprehensively evaluated by neurologists.

Methods:
The IRB waived consent requirements for this retrospective university-hospital study. We extracted and analyzed neurological symptoms, test, and treatment results from all qualifying participants' records and recontacted some for details.

Results:
All 10 participants were female; their PGAD symptoms began between ages 11 to 70 years. Two patterns emerged: 80% reported daily out-of-context sexual arousal episodes (≤30/day) that usually included orgasm and 40% reported lesser, often longer-lasting, nonorgasmic arousals. Most also had symptoms consistent with sacral neuropathy—70% had urologic complaints and 60% had neuropathic perineal or buttock pain. In 90% of patients, diagnostic testing identified anatomically appropriate and plausibly causal neurological lesions. Sacral dorsal-root Tarlov cysts were most common (in 4), then sensory polyneuropathy (2). One had spina bifida occulta and another drug-withdrawal effect as apparently causal; lumbosacral disc herniation was suspected in another. Neurological treatments cured or significantly improved PGAD symptoms in 4/5 patients, including 2 cures.

Conclusions:
Although limited by small size and referral bias to neurologists, this series strengthens associations with Tarlov cysts and sensory polyneuropathy and suggests new ones. We hypothesize that many cases of PGAD are caused by unprovoked firing of C-fibers in the regional special sensory neurons that subserve sexual arousal. Some PGAD symptoms may share pathophysiologic mechanisms with neuropathic pain and itch.
