Clinical features and risk factors of adverse clinical outcomes in central pulmonary embolism using machine learning analysis. Respir Med 2023:107295. [PMID: 37236407 DOI: 10.1016/j.rmed.2023.107295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 04/26/2023] [Accepted: 05/23/2023] [Indexed: 05/28/2023]
Abstract
BACKGROUND In prior studies, central pulmonary embolism (PE) was associated with high clot burden and was considered an independent predictor for thrombolysis. Further information about predictors of adverse outcomes in these patients is needed for better risk stratification. The objective is to describe independent predictors of adverse clinical outcomes in patients with central PE. METHODS Large retrospective, observational, and single-center study of hospitalized patients with central PE. Data were gathered on demographics, comorbidities, clinical features on admission, imaging, treatments, and outcomes. Multivariable standard and Least Absolute Shrinkage and Selection Operator (LASSO) machine learning logistic regressions and sensitivity analyses were used to analyze factors associated with a composite of adverse clinical outcomes, including vasopressor use, mechanical ventilation, and inpatient mortality. RESULTS A total of 654 patients had central PE. The mean age was 63.1 years, 59% were women, and 82% were African American. The composite adverse outcome was observed in 18% (n = 115) of patients. Serum creatinine elevation (odds ratio [OR] = 1.37, 95% CI = 1.20-1.57; p = 0.0001), white blood cell (WBC) count elevation (OR = 1.10, 95% CI = 1.05-1.15; p < 0.001), higher simplified pulmonary embolism severity index (sPESI) score (OR = 1.47, 95% CI = 1.18-1.84; p = 0.001), serum troponin elevation (OR = 1.26, 95% CI 1.02-1.56; p = 0.03), and respiratory rate increase (OR = 1.03, 95% CI = 1.0-1.05; p = 0.02) were independent predictors of adverse clinical outcomes. CONCLUSION Among patients with central PE, higher sPESI score, WBC count elevation, serum creatinine elevation, serum troponin elevation, and respiratory rate increase were independent predictors of adverse clinical outcomes. Right ventricular dysfunction on imaging and saddle PE location did not predict adverse outcomes.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) may result in rapid onset of hypoxemic respiratory failure. This study aimed to characterize the factors and outcomes associated with prolonged hypoxia in patients with COVID-19. Prolonged severe hypoxia (PSH) was defined as hypoxia requiring ≥ 6 L/min of oxygen by nasal cannula or equivalent for more than 10 days. RESEARCH DESIGN AND METHODS This study was designed as a single-center retrospective analysis. Multivariable logistic regression was utilized to assess factors associated with PSH. RESULTS The final sample included 554 patients with 117 (21%) having PSH. Median length of stay of patients with PSH was significantly longer (median IQR: 18 days vs 6 days, p<0.0001). Patients with prolonged severe hypoxia had significantly higher rates of acute venous thromboembolism (p <0.0001) and major bleeding (p<0.004). The presence of cirrhosis (OR 3.32, 95% CI [1.02 to 10.83]) and hypertension (OR 1.99, 95% CI [1.12 to 3.53]) were independently associated with PSH, while outpatient use of anti-platelet agents had an inverse association (OR 0.57, 95% CI [0.36 to 0.91]. CONCLUSION PSH is associated with increased length of stay, morbidity, and mortality. Hypertension and liver cirrhosis were significantly associated with higher odds of PSH, while use of anti-platelet therapy had a protective effect.

Impact of achieving euthyroidism on pulmonary artery systolic pressures in hyperthyroidism-associated pulmonary hypertension - a systematic review. AMERICAN JOURNAL OF CARDIOVASCULAR DISEASE 2022; 12:212-223. [PMID: 36147789 PMCID: PMC9490158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 06/29/2022] [Indexed: 06/16/2023]
Abstract
In this systematic review, we seek to clarify the impact of treatment of hyperthyroidism on pulmonary hypertension in patients with both these conditions. We included 39 of 709 articles retrieved, that studied patients with hyperthyroidism and pulmonary hypertension (PH). From these, those with a documented pre-treatment Pulmonary Artery Systolic Pressure (PASP) > 35 mmHg and complete follow up were analyzed, yielding 3 case series and 22 case reports with a total of 81 cases. A significant improvement in PASP was noted with achieving euthyroidism in the 3 case series. The case reports showed a significant reduction in mean PASP from 60.5 ± 13.2 mmHg to 37.5 ± 10.1 mmHg (p < 0.001) in patients with Grave's disease with achieving euthyroidism. No deaths were reported during the follow up period. Achievement of a euthyroid state in patients with hyperthyroidism is associated with statistically significant reductions in PASP.

Abstract
Identify factors associated with readmission after an index hospital admission for coronavirus disease 2019 (COVID-19) infection in a single center serving an underserved and predominantly minority population. This retrospective descriptive study included 275 patients who tested COVID-19 positive via reverse transcriptase-polymerase chain reaction assay at our institution and who survived the index hospitalization. The main outcomes were 1- and 6-month readmission rates after an index hospitalization for COVID-19. The mortality rate among the readmitted patients was also determined. Factors independently associated with readmission were investigated using multivariable logistic regression. A final sample of 275 patients was included. The mean age was 64.69 ± 14.64 (SD), 133 (48%) were female and 194 (70%) were African American. Their chronic medical conditions included hypertension 203 (74%) and diabetes mellitus 121 (44%). After the hospitalization, 1-month readmission rate was 7.6%, while 6-month readmission rate was 24%. Nine percent of patients who were readmitted subsequently died. Coronary artery disease (CAD) was significantly associated with 6-month readmission odds ratio (OR), 2.15 (95% confidence interval [CI]: 1.04-4.44; p = 0.039) after adjustment for age, gender, ethnicity, and comorbidities. Readmissions were due to cardiac, respiratory, and musculoskeletal symptoms. Hispanic ethnicity was associated with increased readmission OR, 3.16 (95% CI: 1.01-9.88; p = 0.048). No significant difference was found between inflammatory markers or clinical outcomes during the index hospitalization among patients who were readmitted compared to those who were not. A significant number of patients hospitalized for COVID-19 may be readmitted. The presence of CAD is independently associated with high rates of 6-month readmission.

Abstract
We report a case of a 59-year-old male with a one-month history of pleuritic chest pain who was diagnosed with tracheobronchopathia osteochondroplastica (TO). TO is a rare benign condition characterized by protruding submucosal nodules into the tracheobronchial lumen. The disease is generally asymptomatic, with rare cases of progressive nodularity, cough, dyspnoea, and haemoptysis. Diagnosis can be made via bronchoscopic visualization of bony and cartilaginous nodules on tracheal walls. Although generally benign, the rarity of this condition makes diagnosis difficult even for trained pulmonologists and frequently predisposes patients to unnecessary invasive diagnostic testing and improper management of symptoms and contributing co-morbid conditions. We present this case to increase physician and patient awareness about this disease to help improve diagnostic strategy and knowledge of disease manifestations and potential complications.

Abstract
In this Letter to the Editor, Agrawal et al. debate the conflicts that can arise regarding the authorship of case reports. Like all other medical journals, EJCRIM has zero tolerance for the willful undisclosed re-submission of papers that have already been published elsewhere. However, this may occasionally happen by accident, especially in large healthcare institutions in which multiple teams of physicians may care for a patient throughout their illness. EJCRIM endorses and recommends to all potential authors the very sensible suggestions made by Agrawal et al. to avoid such an error occurring. EJCRIM would also encourage authors to consider the following: The first author should ensure that no one else involved in the case has reported it or plans to report it. This is especially important for physicians working in large healthcare centres, and/or for case reports of patients who have been under investigation or treatment for prolonged periods.On rare occasions EJCRIM will consider a case that has already been published, provided that this is fully and explicitly disclosed, and there is a clear reason why re-publication is justified. An example might be where new information has come to light that significantly changes the conclusions of the original report. As in all reports published by EJCRIM the decision to publish will depend on the educational value, or learning points, of the case.

Abstract
Rhinocerebral mucormycosis (RCM) is an angioinvasive fungal infection most often caused by Rhizopus oryzae It is usually associated with an underlying risk factor and is associated with a poor prognosis. There are no consensus guidelines on the optimal management of this aggressive disease; most management decisions are based on case reports and expert opinion. We report a successfully managed case of RCM in an insulin-dependent diabetic, initially presenting with a change in mental status, rapidly progressing to complete right eye blindness and ophthalmoplegia and complicated by multiple cerebral infarctions and abscesses. We describe the diagnostic approach and various therapeutic interventions undertaken to successfully manage our patient.

Abstract
Patients with end-stage renal disease (ESRD) receiving hemodialysis (HD) suffer from a number of metabolic derangements. Ectopic deposition of calcium in the skin, soft tissues, blood vessels, and viscera is a potentially devastating consequence of disorders of calcium and phosphorus homeostasis. We report the case of a patient with ESRD and secondary hyperparathyroidism receiving HD who developed metastatic pulmonary calcification and calciphylaxis following initiation of warfarin therapy after mechanical valve replacement. Because not all patients with ESRD receiving HD develop ectopic calcification, there appears to be a complex cascade of metabolic interactions that predispose patients to this process. Warfarin is a vitamin K antagonist with inhibitory effects not only on proteins of the coagulation cascade, but also on other important protein systems. Its role in ectopic calcium deposition has been the subject of theories and has been reported in the literature, but no link with metastatic pulmonary calcification has been made. Patients receiving HD have an increased incidence of conditions that require chronic anticoagulation with warfarin, such as VTE, atrial fibrillation, and valvular heart disease requiring valve replacement surgery. Bioprosthetic valves should be considered in these patients because of the potential risk of metastatic calcification when warfarin is used in the setting of mechanical valve replacement.

Abstract
BACKGROUND Recent data suggest a reduction in the occurrence of venous thromboembolism in select groups of patients who use statins. The objective of this study is to evaluate the impact of statin use on the occurrence of venous thromboembolism in patients with solid organ tumor. METHODS We conducted a retrospective, case-control study reviewing 740 consecutive patients with a diagnosis of solid organ tumor who were admitted to the Albert Einstein Medical Center, Philadelphia, Penn, between October 2004 and September 2007. Patients treated with anticoagulation therapy before their first admission were excluded. The occurrence of venous thromboembolism, risk factors for venous thromboembolism, and statin use were recorded. Patients who never used statins or had used them for less than 2 months were relegated to the control group. RESULTS The mean age of the study population was 65 years, and 52% of the patients were women and 76% were African American. The occurrence of venous thromboembolism was 18% (N=132), and 26% (N=194) were receiving statins. Among patients receiving statins, 8% (N=16) developed a venous thromboembolism compared with 21% (N=116) in the control group (odds ratio 0.33; 95% confidence interval, 0.19-0.57). A logistic regression analysis including risk factors for venous thromboembolism (metastatic disease, use of chemotherapy, immobilization, smoking, and aspirin use) along with statin use yielded the same results. CONCLUSION This study suggests that the use of statins is associated with a significant reduction in the occurrence of venous thromboembolism. This pleiotropic effect warrants further investigation.

Abstract
We aimed to improve internal medicine residents' deficiencies in pain management and evaluate the effectiveness of our intervention, which included an interactive conference series, e-mail vignettes, and didactic sessions. An anonymous survey was administered at the beginning and at the end of an academic year, before and after the intervention, respectively. We analyzed 65 preintervention and 63 postintervention surveys. Self-perception of competency in pain management increased from 40% to 60% (P = .02). Perception of adequacy of training increased from 38.5% to 55.6% (P = .05). Opioid conversion skills improved by 25% (P = .02). Overall, knowledge did not change significantly, except in the subgroup of residents who had completed the oncology rotation from 0.60 to 0.72 (P = .003). ``Opiophobia'' improved by 20% (P = .05). Documentation of pain improved (rank correlation = 21; P = .02). We concluded that educational and institutional interventions administered over an academic year improved pain management skills and documentation and reduced ``opiophobia'' among residents.

Abstract
Treatment of patients with verapamil overdose remains challenging. Traditional decontamination and supportive measures with intravenous calcium and vasopressors are the mainstays in initial care. Recently, the successful use of rescue hyperinsulinemic euglycemia therapy has been described in multiple cases. Treatment resulted in improved hemodynamic parameters and increased metabolic efficiency in patients with a low-output, myocardial shock state. Information on clinical use of hyperinsulinemic euglycemia therapy in humans is limited to case reports and small case series; no controlled clinical trials have been done. Hyperinsulinemic euglycemia therapy should be considered for patients with calcium channel blocker overdose who do not respond to initial supportive therapy.

Abstract
A 49-year-old woman was brought to the emergency department because of an intentional overdose of sustained-release verapamil along with captopril and glyburide. The estimated interval between ingestion and the time she was found was several hours. Initial findings were blood pressure 72/39 mm Hg, heart rate 32/min, and a score of 9 on the Glasgow Coma Scale. She was intubated and given intravenous fluid and vasopressor support. Decontamination with activated charcoal was instituted. Administration of dopamine and norepinephrine, atropine, sodium bicarbonate, and calcium chloride did not yield significant clinical improvement. Hyperinsulinemic euglycemia therapy was started: a bolus of regular insulin then infusions of insulin and 10% dextrose. After 24 hours of therapy, the bradycardia resolved and the patient’s hemodynamic condition stabilized with normalization of cardiac indices. On day 5 the patient was transferred to the medical unit, and on day 8 she was discharged to psychiatric care.

Abstract
The CD4 lymphocyte plays a pivotal role in both sarcoidosis and HIV infection. Caring for a patient with both conditions represents a diagnostic and therapeutic challenge. We describe a patient, previously diagnosed with sarcoidosis, who subsequently contracted HIV infection. Manifestations of sarcoidosis were clinically silent until highly active anti-retroviral therapy was instituted. Her condition improved with the institution of corticosteroids. The diagnostic and therapeutic dilemmas encountered in patients with both conditions will be discussed including a complete review of the literature.

Abstract
Deficiencies in practice, knowledge, and competence among physicians are important contributing factors to the unsatisfactory level of analgesic care in hospitalized patients. By way of a comprehensive survey, we characterized these deficiencies within an internal medicine residency program as an initial step in designing remedial educational strategies. To do so, an anonymous 43-item survey was administered to residents in an internal medicine program. A total of 61 residents (69 percent) responded. The results indicated that patient-controlled analgesia (PCA), a standardized pain scale, and an opioid equivalence table were underused. Competence in opioid conversion was suboptimal, but completion of an oncology rotation and familiarity with the opioid equivalence table predicted greater competence in this area (p = 0. 00 7 and p = 0.001, respectively). Self-perceptions of adequacy of training and pain-management competence were predictors of knowledge (p = 0.026 andp = 0.038, respectively). Attitudes regarding opioid analgesia were generally satisfactory (i.e., low "opiophobia " score), although the risk of addiction was still overestimated. The characterization of deficiencies in pain management in a residency program is an essential step in the design and implementation of educational interventions. Administration of a comprehensive survey is a simple and effective method of gathering this data and has the additional benefit of promoting awareness of pain management issues. Our experience served to establish, among other findings, the didactic value of experience on an oncology floor; this result substantiates the value of practical experience in the gaining of clinical competence in pain management. Interventions that capitalize on the findings of the survey and the interest in pain management generated by its administration are currently ongoing at our institution.

Do global rating forms enable program directors to assess the ACGME competencies? ACADEMIC MEDICINE : JOURNAL OF THE ASSOCIATION OF AMERICAN MEDICAL COLLEGES 2004; 79:549-56.

Abstract
PURPOSE In 1999 the Accreditation Council for Graduate Medical Education (ACGME) mandated that GME programs require their residents to be proficient in six general competencies. The purpose of this study was to ascertain whether an existing global rating form could be modified to assess these competencies. METHOD A rating form covering 23 skills described in the ACGME competencies was developed. The directors of 92 specialty and subspecialty programs at Thomas Jefferson University Hospital and the Albert Einstein Medical Center in Philadelphia were asked to rate residents at the end of the 2001-02 and 2002-03 academic years. RESULTS Ratings for 1,295 of 1,367 (95%) residents were available. Residents were awarded the highest mean ratings on items tied to professionalism, compassion, and empathy. The lowest mean ratings were assigned for items related to consideration of costs in care and management of resources. Factor analysis indicated that the program directors viewed overall competence in two dimensions of medical knowledge and interpersonal skills. This factor structure was stable for groups of specialties, and residents' gender and training level. Mean ratings in each dimension were progressively higher for residents at advanced levels of training. CONCLUSION Global rating forms, the tool that program directors use most frequently to document residents' competence, may not be adequate to assess the six general competencies. The results are consistent with earlier published research indicating that physicians view competence in just two broad dimensions, which questions the premise of the six ACGME competencies. Further research is needed to validate and measure six distinct dimensions of clinical competence.

Abstract
We report a case of ventilator auto-triggering resulting from tuberculous bronchopleural fistula being managed with chest tube suction. Early recognition of bronchopleural fistula-related auto-triggering is extremely important. Auto-triggering can lead to serious adverse effects, including severe hyperventilation and inappropriate escalation of sedatives and/or neuromuscular blockers (administered to reduce spontaneous breathing efforts). Auto-triggering was confirmed in our patient when tachypnea persisted despite pharmacologic neuromuscular paralysis. Auto-triggering can be reduced or eliminated by decreasing ventilator trigger sensitivity or by decreasing the air leak flow by reducing the degree of chest tube suction.

Abstract
Mitral regurgitation is usually tolerated well in pregnancy, mainly because of left ventricular unloading due to the physiologic decrease in systemic vascular resistance (SVR). We report the case of a patient with mitral regurgitation who had pulmonary edema soon after delivery, which likely was due to a sudden increase in SVR. The sudden changes in SVR should be added to the differential diagnosis when pulmonary edema occurs after delivery in patients with mitral regurgitation.

Abstract
We report the case of a 60-year-old woman with a history of ataxia who sought evaluation after a syncopal episode. A diagnostic workup revealed pulmonary emboli, pernicious anemia (PA), hyperhomocysteinemia, and a G20210A prothrombin gene mutation. She was successfully treated with homocysteine-lowering therapy, including high doses of oral cobalamin. She also received oral anticoagulation for 6 months. At 1 year of follow-up, no further thrombotic episodes had occurred. Our report highlights the thrombotic risk of hyperhomocysteinemia secondary to PA in a patient with the G20210A prothrombin gene mutation.

Abstract
OBJECTIVE Many prognostic variables have been studied in patients with Pneumocystis carinii pneumonia and acquired immunodeficiency syndrome (AIDS). The role of the electrocardiogram in this setting has not been previously evaluated. We analyzed the admission electrocardiogram in patients with Pneumocystis carinii pneumonia and AIDS in an attempt to identify electrocardiogram findings that could be associated with adverse clinical outcomes and worse prognostic variables. DESIGN A retrospective medical chart review. SETTING All confirmed cases of Pneumocystis carinii pneumonia in patients positive for human immunodeficiency virus admitted to Albert Einstein Medical Center from 1994 to 2000. METHODS Patients were assigned increasing severity ranks based on the findings on the admission electrocardiogram (normal sinus rhythm, sinus tachycardia, and right ventricular strain pattern). Data were extracted regarding study outcomes (admission to intensive care unit, mechanical ventilation, and hospital mortality) and prognostic variables. MAIN RESULTS Of the 40 study patients, 14 (35%) had normal sinus rhythm, 15 (37.5%) had sinus tachycardia, and 11 (27.5%) presented with signs of right ventricular strain. The number of admissions to the intensive care unit, use of mechanical ventilation, and hospital mortality rate all increased with the severity of the electrocardiogram findings (p < or =.03). The serum lactate dehydrogenase concentrations and the alveolar-arterial oxygen gradient both increased with the severity of the electrocardiogram findings (p < or =.02). CONCLUSION Electrocardiogram findings of sinus tachycardia and right heart strain are common in Pneumocystis carinii pneumonia. These findings are associated with adverse clinical outcomes as well as worsening of prognostic variables. The electrocardiogram may be useful in predicting outcome in patients with Pneumocystis carinii pneumonia.

Abstract
The mixture of helium and oxygen, called heliox, has been successfully used in the management of different respiratory diseases since 1935. Despite several reports on its usefulness, it is not widely available in acute care facilities and it remains somewhat controversial. In this article we present the case of a 69-year-old woman in whom bilateral vocal cord paralysis developed after radiation therapy and in whom heliox was successfully used to manage her upper airway obstruction. Although heliox offers an additional tool in the treatment of various airway and pulmonary problems, it can be used only as a temporizing agent to allow time for appropriate therapy of the underlying process. Given its beneficial physiologic and clinical effects, it seems that further studies are warranted to define a clear and concise protocol for its use in the emergency setting.

Abstract
Falciparum malaria is frequently associated with significant morbidity and mortality. The use of exchange transfusion as a therapeutic modality for severe cases of malaria has been described previously. We describe a case of a 49 year-old African American gentleman with a history of hemoglobin-SC disease who presented with a severe case of Plasmodium falciparum malaria 3 weeks after having received an infected blood transfusion. His peripheral smear showed the presence of numerous intraerythrocytic ring forms and "banana-shaped" gametocytes with a high-grade parasitemia, estimated at 18%. He was treated with antimalarial chemotherapy and also underwent a 12-unit red blood cell exchange transfusion, decreasing his parasite load to < 1%, as determined on repeat smear. It is prudent to be aware of the efficacy of this adjunctive treatment, especially with ever-increasing travel and a resultant increase in the prevalence of tropical diseases in the United States.

Abstract
The stiff-man syndrome is a rare neuromuscular disorder characterized by progressive rigidity, stiffness, and intermittent spasm of axial and extremity muscles. Its etiology is unknown. Different therapeutic regimens have been used with variable success. We present a case of refractory stiff-man syndrome, in which the symptoms were successfully controlled by the administration of intravenous immunoglobulin (IVIg). This case gives evidence that IVIg can be a safe and an efficient treatment of refractory stiff-man syndrome. The exact indication for and the cost-effectiveness of IVIg in the treatment of this rare entity remain to be determined.
