Introduction: Hyponatremia and/or hypoglycorrhachia are commonly encountered biochemical derangements during the acute stage of childhood tuberculous meningitis (TBM). Few studies have explored the correlation between these derangements and the staging of TBM disease (severity), or explored their role as biomarkers for vascular ischemic events, hydrocephalus, or seizures.Methods: We aimed to identify the prevalence and the correlation between serum hyponatremia (mild, moderate and severe) and/or hypoglycorrhachia in relation to clinical TBM features such as stage of disease, seizures and stroke in children diagnosed with definite and probable TBM, between 1985 and 2015, at Tygerberg Hospital, Cape town, South Africa.Results: The prevalence of hyponatremia was 344 out of 481 (71.5%) patients; 169 (49.1%) had mild hyponatremia, 146 (42.4%) moderate hyponatremia and 29 (8.4%) severe hyponatremia. Children with severe hyponatremia had higher frequency of stroke [odds ratio (OR) 4.36, 95% confidence interval (CI) 1.24–15.35; p = 0.01], brainstem dysfunction (OR 7.37, 95% CI 2.92–18.61; p < 0.01), cranial nerve palsies (OR 2.48, 95% CI 1.04–5.91; p = 0.04) and non-communicating hydrocephalus (OR 2.66, 95% CI 1.09–6.44; p = 0.03). Children with moderate hyponatremia and mild hyponatremia compared to those without hyponatremia similarly were more likely to exhibit signs of brainstem dysfunction (OR 1.91, 95% CI 1.11–3.28; p = 0.02) and hydrocephalus (OR 3.18, 95% CI 1.25–8.09; p = 0.01), respectively. On multivariable analysis only brainstem dysfunction was significantly associated with severe hyponatremia [adjusted odds ratio (aOR) 4.46, 95% CI 1.62–12.30; p < 0.01]. Children with hypoglycorrhachia compared to normoglycorrhachia were more likely to have had longer symptom duration prior to admission (OR 1.87, 95% CI 1.09–3.20; p = 0.02), non-communicating hydrocephalus (OR 1.64, 95% CI 0.99–2.71; p = 0.05), higher cerebrospinal white cell counts (OR 3.00, 95% CI 1.47–6.12; p < 0.01) and higher CSF protein concentrations (OR 2.51, 95% CI 1.49–4.20; p < 0.01). On multivariable analysis raised CSF protein concentration >1 g/L was significantly associated with hypoglycorrhachia (aOR 2.52, 95% CI 1.44–4.40; p < 0.01). Death rates did not differ by sodium level category or presence of hypoglycorrachia, however an increasing trend of children that had demised was noted the more severe the sodium category.Conclusion: Hyponatremia and/or hypoglycorrhachia occur in more than two-thirds of children with TBM. Severe TBM disease complications such as brainstem dysfunction was associated with moderate hyponatremia, while severe hyponatremia was associated with brainstem dysfunction, stroke, cranial nerve palsies and non-communicating hydrocephalus. Cerebrospinal fluid (CSF) glucose depletion correlated with non-communicating hydrocephalus and increased CSF inflammation.

Background: Mitral annular dilation has been shown to challenge successful edge-to-edge therapy with earlier MitraClip generations. Recently, third-generation MitraClip-XTR with extended clip arm length was introduced. We assessed the impact of annular dilation on residual mitral regurgitation (MR) after MitraClip-XTR repair and sought to identify cutoffs associated with suboptimal MR reduction. Methods: We included 107 patients (78.9±6.7 years; 40.2% female) with symptomatic severe MR (46.7% primary MR; 53.3% secondary MR) undergoing MitraClip-XTR repair. Annular dimensions were retrospectively assessed by 2-dimensional and 3-dimensional-transesophageal echocardiography including a semiautomated analysis. Impact of annular diameters and area on suboptimal reduction defined as ≥2+MR on transthoracic echocardiography at discharge was assessed and predictive cutoff values identified. Previously identified predictors of suboptimal outcome after MitraClip therapy were included in multivariable analysis. Results: Technical success was achieved in 93%, 1-year mortality was 23%. Suboptimal MR reduction was observed in 26% and associated with higher 1-year mortality (odds ratio, 4.5 [1.5–14.1]). End-systolic anteroposterior and intercommissural annular diameters, annular area and further vena-contracta width, effective regurgitant orifice area and left atrial volume were associated with suboptimal outcomes. Independent predictors of suboptimal reduction were end-systolic annular area (odds ratio, 1.36 [1.08–1.71] per cm 2 ) and vena-contracta width (odds ratio, 1.47 [1.04–2.09] per mm). On receiver operating characteristic analysis, 3-dimensional-transesophageal echocardiography end-systolic anteroposterior diameter >40.5 mm, intercommisural diameter >40.5 mm, and annular-area >12.50 cm 2 were the most predictive thresholds for suboptimal reduction. If all 3 annular measurements exceeded the determined threshold values, the risk for suboptimal reduction increased by 17-fold. Conclusions: Annular dilation was found to challenge successful edge-to-edge therapy also with extended-reach MitraClip-XTR. Our proposed thresholds for preprocedural annular dimensions may serve as guidance for improved patient selection in edge-to-edge repair.

Abstract OBJECTIVE Cerebral infarction would be expected to be associated with poor outcome after aneurysmal subarachnoid hemorrhage (SAH), although there are few data on which to base this assumption. The goals of this study were to determine the impact of cerebral infarction on outcome and to examine predictors of infarction in these patients. METHODS Univariate and multivariable statistical methods were used to examine the impact of cerebral infarction on the Glasgow Outcome Scale score 3 months after SAH among 3567 patients entered into four prospective, randomized, double-blind, placebo-controlled trials of tirilazad conducted in neurosurgical centers around the world between 1991 and 1997. Patient demographics, clinical variables, radiographic characteristics, and treatment variables associated with cerebral infarction were also determined by the same methods. RESULTS Seven hundred and seven (26%) out of 2741 patients with complete data had cerebral infarction on computed tomographic scans 6 weeks after SAH. Multivariable logistic regression showed that cerebral infarction increased the odds of unfavorable outcome by a factor of 5.4 (adjusted odds ratio, 5.4; 95% confidence interval, 4.2–6.8; P < 0.0001), which was a higher odds ratio than all other factors associated with outcome. The proportion of explained variance in outcome was also highest for cerebral infarction and accounted for 39% of the explained variance. Multivariable analysis found that cerebral infarction was significantly associated with increasing patient age, worse neurological grade on admission, history of hypertension or diabetes mellitus, larger aneurysm, use of prophylactically or therapeutically induced hypertension, temperature more than 38°C 8 days after SAH, and symptomatic vasospasm. CONCLUSION Cerebral infarction was strongly associated with poor outcome after aneurysmal SAH. The most important potentially treatable factor associated with infarction was symptomatic vasospasm.

Background: This study evaluates the impact of the 2018 allocation policy change on outcomes of orthotopic heart transplantation (OHT) in patients bridged with intra-aortic balloon pumps (IABPs). Methods: Adult (≥18 years) patients undergoing OHT between 2013 and 2019 who were bridged with an IABP were stratified based on temporal relation to the policy change. Univariate analysis was used to compare baseline characteristics and postoperative outcomes. Multivariate Cox regression analysis was used to estimate risk-adjusted predictors of post-transplant mortality. Results: A total of 1342 (8.6%) OHT patients were bridged with an IABP during the study period. Rates of bridging with IABP to OHT increased significantly after the policy change (7.0% versus 24.9%, P <0.001). The mean recipient age was 54.1±12.1 years with 981 (73.1%) patients being male. Baseline characteristics were similar between the 2 groups whereas post–policy change patients spent fewer days on the waitlist (15 versus 35 days, P <0.001), had longer ischemic times (3.5 versus 3.0 hours, P <0.001), and received organs from a greater distance (301 versus 105 miles, P <0.001). By multivariable analysis, days on the waitlist (for every 30 days; odds ratio, 1.01 [95% CI, 1.00–1.02], P =0.031) and diabetes mellitus (odds ratio, 1.87 [95% CI, 1.16–3.02], P =0.011) emerged as significant predictors of post-transplant mortality. After the policy change, waitlisted patients requiring IABP support were more likely to survive to transplant (76.4 versus 89.8%, P <0.001). Conclusions: IABP utilization has increased over 3-fold since the 2018 policy change with improved waitlist outcomes and comparable post-OHT survival. Thus, bridging patients to OHT with IABPs appears to be an effective strategy in the current era.

Abstract Background The association of recovered acute kidney injury (AKI) with mortality was controversial. Our study aims to investigate the impact of recovered AKI on mortality in patients following coronary angiography (CAG). Methods Our study retrospectively enrolled 3,970 patients with pre-operative serum p creatinine (Scr) and twice measurements within 48hours after procedure. Recovered AKI defined as the diagnosis of AKI (Scr &gt;0.3 mg/dL or &gt;50% from the baseline level) on day 1 when Scr failed to meet the criteria for AKI on the day 2. Maintained AKI was defined as AKI not meeting the definition for recovered AKI. The primary outcome was 1-year all-cause mortality. Multivariable logistic regression was used to assess the association between recovered AKI and 1-year mortality. Results Among 3,970 participants, 861 (21.7%) occurred AKI, of whom 128 (14.9%) was recovered AKI and 733 (85.1%) was maintained AKI. 312 (7.9%) patients died within 1-year after admission. After multivariable analysis, recovered AKI was not associated with higher 1-year mortality (adjusted odds ratio [aOR], 1.37; CI, 0.68–2.51) compared without AKI. Among AKI patients, Recovered AKI was associated with a 52% lower 1-year mortality compared with maintained AKI. Additionally, maintained AKI was significantly associated with higher 1-year mortality (aOR, 2.67; CI, 2.05–3.47). Conclusions Our data suggested that recovered AKI within 48h was a common subtype of AKI following CAG, without increasing mortality. More attention need to be paid to the patients suffering from maintained AKI following CAG. FUNDunding Acknowledgement Type of funding sources: None.

Abstract We investigated the impact of hypernatremia on mortality of neurocritically ill patients. Among neurosurgical patients admitted to the intensive care unit (ICU) from January 2013 to December 2019, the patients who were hospitalized in the ICU for more than 5 days included. Hypernatremia was defined as the highest serum sodium level exceeding 150 mEq/L observed. Among 1,146 patients, 353 patients (30.8%) showed hypernatremia. Based on propensity score matching, 290 pairs were analyzed. Hypernatremia group had higher rates of in-hospital mortality compared with non-hypernatremia group in overall and matched population (p < 0.001 and p = 0.001, respectively). In multivariable analysis of propensity score-matched population, moderate and severe hypernatremia were significantly associated with in-hospital mortality (adjusted odds ratio [OR]: 4.58, 95% confidence interval [CI]: 2.15 – 9.75 and adjusted OR: 6.93, 95% CI: 3.46 – 13.90, respectively) compared with the absence of hypernatremia. However, in-hospital mortality was not significantly different between non-hypernatremia and mild hypernatremia groups (p = 0.720). Interestingly, mild hypernatremia group of matched population showed the best survival rate. Eventually, moderate and severe hypernatremia were associated with poor clinical outcomes in neurocritically ill patients. However, prognosis of the patients with mild hypernatremia was similar with those without hypernatremia.

Objective: To assess the clinical profile and outcome of patients admitted with the diagnosis of tuberculous meningitis (TBM) at neurology unit of a tertiary care teaching hospital of Pakistan. Study Design: Cross-sectional study. Place and Duration of Study: Neurology department, Pak Emirates Military Hospital Rawalpindi, from Dec 2018 to Jun 2019. Methodology: This study was conducted on 69 patients of tuberculous meningitis admitted. Demographic profile included age, gender, and the symptoms with which the patient presented. Neurological complications were also documented among the target population. Outcomes included recovery, shifting to intensive care unit and death. Results: A total of 69 patients admitted in neurology ward diagnosed and managed as tuberculous meningitis in the study duration time. Male to female ratio was 1.4:1. Mean age of patients diagnosed with tuberculous meningitis in our study was 34.23 ± 3.915 years. Most of the patients presented with the fever followed by headache. Out of 69 patients, 41 (59.4%) recovered, 22 (31.9%) were shifted to the intensive care unit and 6 (8.7%) died. Seizures were the commonest neurological complication faced by the patients followed by cranial nerve palsies. Conclusion: Fever and headache were common symptoms with which patients of tuberculous meningitis presented in our study population. Most of the patients recovered in the ward but a high percentage required intensive care unit admission as well. Seizures and cranial nerve palsies were commonly experienced complication by patients included in our study.

Objective. To compare maternal morbidity in HIV-infected and uninfected pregnant women.Methods. Major maternal morbidity (severe febrile illness, illnesses requiring hospital admissions, surgical revisions, or illnesses resulting in death) was measured prospectively in a cohort of HIV-infected and uninfected women followed from 36 weeks of pregnancy to 6 weeks after delivery. Odds ratios of major morbidity and associated factors were examined using logistic regression.Results. Major morbidity was observed in 46/129 (36%) and 104/390 (27%) of the HIV-infected and HIV-uninfected women, respectively, who remained in followup. In the multivariable analysis, major morbidity was independently associated with HIV infection, adjusted odds ratio (AOR) 1.7 (1.1 to 2.7), nulliparity (AOR 2.0 (1.3 to 3.0)), and lack of, or minimal, formal education (AOR 2.1 (1.1 to 3.8)).Conclusions. HIV was associated with a 70% increase in the odds of major maternal morbidity in these Ugandan mothers.

ObjectIntracranial chondrosarcomas have a high risk of recurrence after surgery. This retrospective study of patients with intracranial chondrosarcoma was conducted to determine the long-term results of microsurgery followed by Gamma Knife surgery (GKS) for residual tumor or recurrence.MethodsThe authors treated nine patients whose median age was 36 years. Seven patients had low-grade chondrosarcomas (LGCSs), whereas mesenchymal chondrosarcomas (MCSs) were diagnosed in two. Radiosurgery was performed in eight patients, whereas one patient declined further surgical intervention and tumor-volume reduction necessary for the GKS.The patients were followed up for 15 to 173 months (median 108 months) after diagnosis and 3 to 166 months (median 88 months) after GKS. Seven patients had residual tumor tissue after microsurgery, and two operations appeared radical. In the two latter cases, tumors recurred after 25 and 45 months. Thus, definite tumor control was not achieved after surgery alone in any patient, whereas the addition of radiosurgery allowed tumor control in all six patients with LGCSs. Two of these patients experienced an initial tumor regrowth after GKS; in both cases the recurrences were outside the prescribed radiation field. The patients underwent repeated GKS, and subsequent tumor control was observed. An MCS was diagnosed in the remaining two patients. Complications after microsurgery included diplopia, facial numbness, and paresis. After GKS, one patient had radiation necrosis, which required microsurgery, and two patients had new cranial nerve palsies.Conclusions Tumor control after microsurgery alone was not achieved in any patient, whereas adjuvant radiosurgery provided local tumor control in six of eight GKS-treated patients. Tumor control was not achieved in the two patients with MCS. Similar to other treatments for intracranial chondrosarcoma, morbidity after micro- and radiosurgical combination therapy was high and included severe cranial nerve palsies.


Objective: While the use of intraoperative laser angiography (SPY) is increasing in mastectomy patients, its impact in the operating room to change the type of reconstruction performed has not been well described. The purpose of this study is to investigate whether SPY angiography influences post-mastectomy reconstruction decisions and outcomes. Methods and materials: A retrospective analysis of mastectomy patients with reconstruction at a single institution was performed from 2015-2017.All patients underwent intraoperative SPY after mastectomy but prior to reconstruction. SPY results were defined as ‘good’, ‘questionable’, ‘bad’, or ‘had skin excised’. Complications within 60 days of surgery were compared between those whose SPY results did not change the type of reconstruction done versus those who did. Preoperative and intraoperative variables were entered into multivariable logistic regression models if significant at the univariate level. A p-value <0.05 was considered significant. Results: 267 mastectomies were identified, 42 underwent a change in the type of planned reconstruction due to intraoperative SPY results. Of the 42 breasts that underwent a change in reconstruction, 6 had a ‘good’ SPY result, 10 ‘questionable’, 25 ‘bad’, and 2 ‘had areas excised’ (p<0.01). After multivariable analysis, predictors of skin necrosis included patients with ‘questionable’ SPY results (p<0.01, OR: 8.1, 95%CI: 2.06 – 32.2) and smokers (p<0.01, OR:5.7, 95%CI: 1.5 – 21.2). Predictors of any complication included a change in reconstruction (p<0.05, OR:4.5, 95%CI: 1.4-14.9) and ‘questionable’ SPY result (p<0.01, OR: 4.4, 95%CI: 1.6-14.9). Conclusion: SPY angiography results strongly influence intraoperative surgical decisions regarding the type of reconstruction performed. Patients most at risk for flap necrosis and complication post-mastectomy are those with questionable SPY results.
