Abstract
OBJECTIVE To construct algorithms with a sequential decision analysis pathway for monitoring of the fetal heart rate and managing fetal heart rate bradycardia, late decelerations and tachycardia during labour. POPULATION Low-risk pregnant women in labour with singleton cephalic term pregnancies. SETTING Institutional births in low- and middle-income countries. SEARCH STRATEGY We sought relevant published clinical algorithms, guidelines and randomised trials/reviews by searching the Cochrane Library, PubMed and Google on the terms: "fetal AND heart AND rate AND algorithm AND (labour OR intrapartum)", up to March 2020. CASE SCENARIOS The two scenarios included were fetal heart rate bradycardia or late decelerations (potentially related to uterine rupture, placental abruption, cord prolapse, maternal hypotension, uterine hyperstimulation or unexplained) and fetal heart rate tachycardia (potentially related to maternal hyperthermia, infection, dehydration or unexplained). The algorithms provide pathways for definition, assessment, diagnosis, interventions to correct the abnormalities and ongoing monitoring leading to mode of birth, and linking to other algorithms in the series. CONCLUSIONS The algorithms provide a framework for monitoring and managing fetal heart rate bradycardia, late decelerations and tachycardia during labour. We emphasise the inherent diagnostic inaccuracy of fetal heart rate monitoring, the tendency to over-diagnose fetal compromise, the need to consider fetal heart rate information in the context of other clinical features and the need to engage in informed, shared, family-centred decision-making. We note the need for further research on methods of fetal assessment during labour including clinical fetal arousal testing and the rapid biophysical profile test. TWEETABLE ABSTRACT Decision analysis algorithms for fetal bradycardia, late decelerations and tachycardia highlight diagnostic limitations.

Abstract
Background Adjacent segment pathology (ASP) following cervical disc arthroplasty (CDA) or anterior cervical discectomy and fusion (ACDF) is identified by imaging (RASP) or clinical symptoms (CASP). Clinical symptoms of CASP have been broadly defined, but subsequent adjacent-level surgeries are clear indicators of CASP. Current literature remains inconsistent in the incidence and potential predictors of CASP. Here, we will evaluate a robust data set for the incidence of CASP resulting in subsequent surgery, attempt to identify factors that might affect CASP, and analyze the association of CASP with patient-reported outcomes (PROS) and RASP. Methods Data were prospectively collected during a US Food and Drug Administration randomized, multicenter, investigational device exemption trial comparing CDA (Mobi-C, Zimmer Biomet, Westminster, CO) with ACDF. CASP was defined as any adjacent-level subsequent surgical intervention. Post hoc analyses were conducted on the incidence, time to CASP diagnosis, and relationship of CASP with patient demographics. Longitudinal retrospective case-control analysis was used to assess the correlation of CASP to PROs and radiographic adjacent segment pathology (RASP). Results Kaplan-Meier estimates indicated significantly lower probability of CASP over time for 1-level (P = .002) and 2-level (P = .008) CDA patients. Treatment with ACDF and younger age were associated with higher CASP risk. CDA was more effective than ACDF (70.5%; 95% CI = 45.1, 84.2; P < .0001) at preventing CASP. Case-control analysis indicated increased probability of CASP for patients with grade 3/4 RASP, but the difference was not statistically significant. When we pooled CASP patients, the median grade of RASP at the visit prior to surgery was 1, with only 6 patients presenting with grade 3/4 RASP. Conclusions Patients treated with CDA have a lower incidence of CASP than do patients treated with ACDF, although the mechanism remains unclear. CASP and RASP remain uncorrelated in this large data set, but other predictive variables such as treatment, age, and number of levels should be further investigated.

Abstract
Background Adjacent segment pathology (ASP) remains a concern following treatment with cervical disc arthroplasty (CDA) and anterior cervical discectomy and fusion (ACDF). Radiographic ASP (RASP) is ASP identified on imaging, which may or may not include clinical symptoms. The risk factors for development of RASP and its clinical effects remain controversial. In part 1 of a 2-part publication we evaluate the incidence and predictors of RASP as well as determine whether any association exists between RASP and patient-reported outcomes (PROs). Methods Data were prospectively collected during a US Food and Drug Administration randomized, multicenter, investigational device exemption trial comparing CDA (Mobi-C; Zimmer Biomet, Westminster, CO) with ACDF. Multiple post hoc analyses were conducted on RASP as it related to demographics and patient outcomes. Kaplan-Meier estimates of time to Kellgren-Lawrence (K-L) grade 3/4 were calculated separately for all groups. Multivariate Cox proportional hazard models were used analyze whether RASP was associated with patient preoperative demographic characteristics and preoperative and postoperative radiographic characteristics. The association of RASP with PROs was analyzed using generalized estimating equations and matched, retrospective cohort analysis. Results The incidence of grade 3/4 RASP was lower for patients treated with CDA when initial treatment was at 1 level (27% vs 47%, P < .0001) and at 2 levels (14% vs 49%, P < .0001). Kaplan-Meier estimates indicated significantly lower probability of grade 3/4 RASP over time for patients receiving CDA (P < .001). Treatment with ACDF, treatment of 1 level, higher age, body mass index, higher preoperative physical components score, and a lower Cobb angle were associated with elevated risk of grade 3/4 RASP. CDA was shown to be more effective than ACDF (64.4%; 95% CI = 50.9, 74.2; P < .0001) at preventing RASP. Conclusions The incidence and risk of RASP is decreased when patients are treated with CDA compared with ACDF. Although the mechanism of CDA that generates this protective effect is not understood, PROs remain unaffected through 7 years despite changes in RASP.

Abstract
Background Heterotopic ossification (HO) is a known risk following cervical total disc replacement (CTDR) surgery, but the cause and effect of HO are not well understood. Reported HO rates vary, and few studies are specifically designed to report HO. The effects on outcomes, and the risk factors for the development of HO have been hypothesized and reported in small-population, retrospective analyses, using univariate statistics. Methods Posthoc, multiple-phase analysis of radiographic, clinical, and demographic data for CTDR as it relates to HO was performed. HO was radiographically graded for 164 one-level and 225 two-level CTDR patients using the McAfee and Mehren system. Analysis was performed to correlate HO grades to clinical outcomes and to evaluate potential risk factors for the development of HO using demographics and baseline clinical measures. Results At 7 years, 1-level clinically relevant HO grades were 17.6% grade 3 and 11.1% grade 4. Two-level clinically relevant HO grades, evaluated using the highest patient grade, were 26.6% grade 3 and 10.8% grade 4. Interaction between HO and time revealed significance for neck disability index (NDI; P = .04) and Visual Analog Scale (VAS) neck pain (P = .02). When analyzed at each time point NDI was significant at 48-84 months and VAS neck at 60 months. For predictors 2 analyses were run; odds ratios indicated follow-up visit, male sex, and preoperative VAS neck pain are related to HO development, whereas hazard ratios indicated male sex, obesity, endplate coverage, levels treated, and preoperative VAS neck pain. Conclusions This is the largest study to report HO rates, and related outcomes and risk factors. To develop an accurate predictive model, further large-scale analyses need to be performed. Based on the results reported here, clinically relevant HO should be more accurately described as motion-restricting HO until a definitive link to outcomes has been established.

Abstract
OBJECTIVE The aim of this study was to educate medical professionals about potential financial impacts of improper diagnosis-related group (DRG) coding in adult spinal deformity (ASD) surgery. METHODS Medicare's Inpatient Prospective Payment System PC Pricer database was used to collect 2015 reimbursement data for ASD procedures from 12 hospitals. Case type, hospital type/location, number of operative levels, proper coding, length of stay, and complications/comorbidities (CCs) were analyzed for effects on reimbursement. DRGs were used to categorize cases into 3 types: 1) anterior or posterior only fusion, 2) anterior fusion with posterior percutaneous fixation with no dorsal fusion, and 3) combined anterior and posterior fixation and fusion. RESULTS Pooling institutions, cases were reimbursed the same for single-level and multilevel ASD surgery. Longer stay, from 3 to 8 days, resulted in an additional $1400 per stay. Posterior fusion was an additional $6588, while CCs increased reimbursement by approximately $13,000. Academic institutions received higher reimbursement than private institutions, i.e., approximately $14,000 (Case Types 1 and 2) and approximately $16,000 (Case Type 3). Urban institutions received higher reimbursement than suburban institutions, i.e., approximately $3000 (Case Types 1 and 2) and approximately $3500 (Case Type 3). Longer stay, from 3 to 8 days, increased reimbursement between $208 and $494 for private institutions and between $1397 and $1879 for academic institutions per stay. CONCLUSIONS Reimbursement is based on many factors not controlled by surgeons or hospitals, but proper DRG coding can significantly impact the financial health of hospitals and availability of quality patient care.

Abstract
BACKGROUND Bone graft material for lumbar fusion was historically autologous bone graft (ABG). In recent years alternatives such as allograft, demineralized bone matrix (DBM), ceramics, and bone morphogenetic protein (BMP) have gained favor, although the complications of these are not fully understood. Bioactive amniotic suspension (BAS) with allograft is a new class of material derived from human amniotic tissue. METHODS Eligible patients receiving a one or two level lumbar interbody fusion with Nucel, a BAS with allograft, were contacted and scheduled for a mininmim 12 month follow-up visit. Patients were evaluated for fusion using CT's and plain radiographs. Clincal outcomes, including ODI, VAS back and leg were collected, as well as comorbidities including BMI, smoking status, diabetes and previous lumbar surgery. RESULTS One-level patients (N=38) were 71.1% female with mean age of 58.4 ± 12.7 and mean BMI of 30.6 ± 6.08. Two-level patients (N=34) were 58.8% female with mean age of 49.3 ±10.9 and mean BMI of 30.1 ± 5.82. Kinematic fusion was achieved in 97.4% of one-level patients and 100% of two-level patients. Baseline comorbidities were present in 89.5% of one-level patients and 88.2% of two-level patients. No adverse events related to BAS were reported in this study. CONCLUSION Fusion status is evaluated with many different biologics and varying methods in the literature. BAS with allograft in this study demonstrated high fusion rates with no complications within a largely comorbid population. Although a small population, BAS with allograft results were encouraging for one and two-level lumbar interbody fusion in this study. Further prospective studies should be conducted to investigate safety and efficacy in a larger population.

Abstract
OBJECTIVE To estimate maternal mortality ratio (MMR) and determine maternal death causes and trends in Greater Soweto, Johannesburg, South Africa. DESIGN Cross-sectional study. SETTING Chris Hani Baragwanath Maternity Hospital (CHBMH) in Greater Soweto. POPULATION Maternal deaths at CHBMH. METHODS Record review of maternal deaths from 1997 to 2012, using hospital death records, with denominator data from the district health information system and the hospital. MAIN OUTCOME MEASURES Maternal mortality ratio per 100,000 live births, and causes of death classified as in the South African confidential enquiries. RESULTS There were 479 deaths, with a peak MMR of 139 in 2004 and a decline to 86 in 2012. Of 332 women tested, 245 (74%) were HIV-infected. Nonpregnancy-related infection (40%) was the most frequent cause of death, followed by hypertension (16%) and obstetric haemorrhage (13%). HIV infection rates in these groups were 92%, 30% and 61%, respectively. Previous caesarean section was associated with obstetric haemorrhage death (odds ratio [OR] 3.2, 95% confidence interval [95% CI] 1.7-6.0), maternal age ≥35 years with hypertension death (OR 2.2, 95% CI 1.2-3.7) and antenatal anaemia with nonpregnancy-related infection death (OR 4.0, 95% CI 2.3-6.9), compared with other causes of death. CONCLUSION There is evidence of a decline in MMR since HIV treatment for pregnant women was introduced in 2004. Previous caesarean section, advanced maternal age, and anaemia were associated with death from obstetric haemorrhage, hypertensive disorders of pregnancy and nonpregnancy-related infections, respectively. MMR may be further reduced with accelerated initiation of HIV treatment during pregnancy.

Abstract
INTRODUCTION This study was conducted to compare and contrast published in vitro intrinsic clearance values reported for compounds from different laboratories and the predictivity of these data to project in vivo clearance. METHODS A total of 103 compounds were selected for investigation and an exhaustive literature search was conducted to identify in vitro intrinsic clearance (CL,i) values for comparative purposes. The simple well-stirred model was used to predict in vivo clearance using these in vitro intrinsic clearance values. RESULTS Data were available in the literature for <10% of the compounds of interest in rat, dog, monkey, or human S9, as well as <10% for dog or monkey microsomes or hepatocytes. Therefore, this comparative exercise was limited to rat and human microsomes and hepatocytes. Examination of the available CL,i values indicated a substantial (up to 100 s-fold) variation in values reported in the literature; this variability translated into substantial variation in predicted in vivo clearance. DISCUSSION The literature paucity and variability described here demonstrate the importance of generating experimentally consistent de novo CL,i data for the purpose of method validation or in vitro-in vivo scaling.

Abstract
OBJECTIVE In view of recent suggestions that human immunodeficiency virus (HIV) infection may protect against preeclampsia, this study was done to evaluate whether untreated HIV-positive pregnant women have a lower rate of preeclampsia-eclampsia than HIV-negative women. METHODS Subjects for this study were pregnant women from Soweto, South Africa, who gave birth from March to December 2002 at midwife-run clinics or at the Chris Hani Baragwanath Hospital and in whom the HIV status was known. A sample size calculation indicated that 2,588 subjects would be required to show statistical significance at P <.05 with a power of 80% for a reduction in the rate of preeclampsia from 8% to 5% with HIV seropositivity, assuming an HIV seroprevalence rate of 30%. Data collection was by record review from randomly selected patient files and birth registers. RESULTS In the total sample of 2,600 women, 1,797 gave birth at the hospital and 803 at the midwife-run clinics. The HIV seroprevalence rate was 27.1%. Hypertension was found in 17.3% of women, with 5.3% having preeclampsia-eclampsia. The rates of preeclampsia-eclampsia were 5.2% in HIV-negative and 5.7% in HIV-positive women (P =.61). CD4 count results were available for only 13 women (0.5%). CONCLUSION Human immunodeficiency virus seropositivity was not associated with any reduction in the risk of developing preeclampsia-eclampsia.

Abstract
A randomized experimental design was used to assign participants to an integrated mental health and substance use treatment program or to standard hospital treatment. A multilevel, nonlinear model was used to estimate hospital treatment effects on days of alcohol use for persons with serious mental illness and substance use disorders over 18 months. The integrated treatment program had a significant effect on the rate of alcohol use at 2 months postdischarge, reducing the rate of use by 54%. Motivation for sobriety at hospital discharge, posttreatment self-help attendance, and social support for sobriety were also found to reduce the rate of use during the follow-up period. Implications for mental health treatment and aftercare support are discussed.

Abstract
An association has been noted between trisomy 18 and genitourinary abnormalities, with six previous reports of the prune-belly syndrome occurring in patients with trisomy 18. We have observed a 120-g fetus of 18 weeks' gestational age at autopsy in whom there was severe prune-belly syndrome and trisomy 18. Serial histologic sections and reconstruction of the lower urinary tract demonstrated severe prostatic hypoplasia with a dilated, angulated prostatic urethra. Obstruction appeared to be present at the internal sphincter as a result of loss of prostatic support of the bladder. The bladder was distended and hypertrophic, and had a disruption of its wall near the apex. Massive ascites and intraabdominal urine accumulation had produced abdominal distention and pulmonary hypoplasia. The findings in this case lend support to the concept of prostatic hypoplasia as a cause of prune-belly syndrome and to the unexplained association between trisomy 18 and genitourinary anomalies including the prune-belly syndrome.

Abstract
The purpose of this study was to investigate to what extent students' assessments of their clerkship experiences varied in relation to perceptions of self-improvement, the time of year in which the clerkship experience took place, and the origin of the assessment device (departmental versus institutional). All students enrolled in each of six surgery clerkship rotations over the course of 1 academic year (224 students) were administered two questionnaires on completion of the clerkship. One questionnaire was institutionally developed and supported, whereas the other was departmentally sponsored. Results of multiple regression analyses indicated that (1) when students felt their medical skills had improved as a result of clerkship participation, the clerkship was considered of high quality; (2) students' perceived improvement in communication skills decreased as the academic year progressed; and (3) students did not alter their responses to the questionnaires based on whether the instrument was institutionally or departmentally sponsored.

Abstract
A patient studied at autopsy was found to have a post-operative wound infection with Aspergillus flavus in which there was the formation of fungal structures resembling sclerotia. The ability of Aspergillus to form sclerotia in tissue appears to be rare and is related to the strain of Aspergillus flavus. Since sclerotia are considered as structures capable of withstanding dramatic shifts in the environment, the production of these in tissue may affect the efficacy of antifungal therapy.

Abstract
The Type A behavior pattern (TABP) is a recognized risk factor for coronary heart disease (CHD), and yet treatments aimed at its modification are not in widespread use. We reviewed the literature of controlled studies (N = 18) of the psychologic treatment of the TABP and of CHD with the statistical method of "meta-analysis." The results of each study were converted to a standardized "Effect Size" (ES). The mean ES for TABP measures was 0.61 +/- 0.20 (95% confidence interval) (p less than 0.001), indicating that after treatment subjects across all studies reduced their TABP scores by half a standard deviation. The combined significance probability (pc) across studies for reduction in 3-year combined mortality and myocardial infarction was pc less than 0.0001, corresponding to a reduction in coronary events of roughly 50% after psychologic treatment. This finding must be approached with caution because it is based on only two studies. The analysis suggested that a combination of treatment techniques is most effective in reducing TABP and CHD recurrences. The literature was critiqued, and limitations of the findings are discussed. We conclude that psychologic intervention to reduce TABP may improve clinical outcome of CHD and that this deserves further study and preliminary clinical application.

Abstract
The Type A behavior pattern (TABP) has been demonstrated as a risk factor for the development of coronary heart disease (CHD). Psychophysiologic studies suggest that the TABP may be associated with autonomic hyperreactivity to a variety of stressors. Recent studies report an association of TABP with autonomic hyperreactivity in patients under general anesthesia for coronary artery bypass surgery. The present study did not find a significant correlation between the TABP and intraoperative rise in blood pressure for 44 noncardiac patients undergoing anesthesia for elective general surgical procedures. Suggestive associations were found in sub-samples with family history of CHD or age greater than 60 years. Thus, the TABP may be correlated with heightened physiologic response under anesthesia only in selected populations.

Abstract
One hundred consecutive patients who underwent coronary artery bypass surgery at the Columbia-Presbyterian Medical Center from December 1972 through February 1975 were evaluated at surgery and then followed for as long as 4 1/2 years to study their postoperative psychosocial and behavioral course. One patient died during the first 30 days. At 4 1/2 years, 23 patients were reported as deceased, 15 from cardiac causes. The majority of the long-term survivors had substantially less angina and greater exercise capacity; surgery did not increase the number of patients who were employed, but led to substantial improvements in the quality of life, including general pleasure, reduction of anxiety and depression and subjective improvement in job and family roles. Sexual adjustment improved the least; the frequency of sexual relations tended to decrease. Compliance with the medical regimen was relatively good for smoking and exercise, but not for diet or type A behavior, suggesting a need for psychological intervention.

Abstract
Several recent studies have examined the association between Type A personality and coronary artery disease (CAD) by coronary angiography. Most of these studies have reported a significant association. The present study is an attempt at further confirmation, using a new non-invasive technique for measuring CAD. Subjects were 53 patients undergoing routine exercise stress tests with concomitant thallium-201 myocardial perfusion studies. Five aspects of Type A behavior were assessed by the use of the Rosenman-Friedman Semistructured Interview, and each was rated on a three-point scale. Severity of CAD was independently estimated on a four-point scale. Pearson correlation coefficients were separately computed for patients with and without reported history of myocardial infarction (MI). For 37 patients without reported MI, CAD severity was significantly correlated with Overall Type A (r = -0.53), Vocal Characteristics (r = -0.53), Job Involvement (r = -0.36) and Aggressiveness (r = -0.48), but not Time Urgency (r = -0.25). For 16 patients with reported MI, CAD severity was significantly correlated with Job Involvement only (r = +0.49). The data are consistent with the association of Type A personality and coronary atherogenesis, but may also reflect Type A psychological and physiological characteristics. Future studies may be able to examine these and other aspects of Type A behavior using this noninvasive technique in more diverse patient populations.

Abstract
Systemic hypertension has been reported as common during coronary artery bypass surgery. The coronary-prone Type A behavior pattern has been associated with heightened reactivity of the sympathetic nervous system. Therefore, the possible relationships between the two was explored. Significant correlations were found between systolic blood pressure rise during surgery and interview ratings of overall Type A (p < 0.05), aggressive content (p < 0.01), and job commitment (p < 0.001). A statistically association was also found between diastolic pressure rise and the job commitment rating (p < 0.01). Significant correlations were still present after controlling for the role of physical predictors of blood pressure rise by statistical multiple regression analysis. The data suggest that patients with Type A behavior characteristics manifest an autonomic hyperactivity which is present under general anesthesia. This hyperactivity may contribute to the association of Type A behavior pattern and coronary heart disease.

Abstract
Psychological intervention studies designed to reduce cardiac morbidity are reviewed. Preliminary findings suggest that various psychotherapeutic modalities may be effective. Such studies also provide an avenue through which the physical and psychological mechanisms involved in coronary heart disease and their interactions may be clarified. Implications for clinical interventions are also discussed.

Abstract
One hundred forty-seven consecutive patients scheduled to undergo coronary angiography were classified according to the type-A behavior pattern. Statistically significant correlations were found between diseases severity and the physical risk factors cholesterol, smoking, hypertension, sex, and age. The correlation of the behavior pattern with angiographic disease severity was of the same magnitude as that of the other risk factors except cholesterol, which was greater. The association between the behavior pattern and severity persisted after adjustments had been made for the effects of five other major risk factors.

Abstract
The incidence of postoperative delirium following coronary artery bypass surgery was 28%. This rate is comparable to that after open-heart surgery. However, of those variables which were previously found to correlate with delirium in the open-heart group, only severity of postoperative illness in the recovery room significantly correlated with delirium in patients having bypass. The relationship between personality type and delirium, previously found to be signficant, was suggestively associated in these patients. A history of myocardial infarction prior to surgery was significantly associated with delirium.
