Cardiovascular disease is prevalent in the older population, making older patients susceptible to complications, including cardiac arrest. Early intervention via cardiopulmonary resuscitation or another form of emergency cardiovascular care can reduce mortality in this population. In 2000, the American Heart Association, in conjunction with various international organizations, published guidelines for cardiopulmonary resuscitation and emergency cardiovascular care, which include a section on advanced cardiac life support (ACLS). By understanding these ACLS recommendations, primary care physicians will be better prepared to assist their older patients during a cardiac emergency. In the geriatric population, awareness of the patients' wishes regarding initiation of cardiopulmonary resuscitation is important in deciding if it is appropriate to proceed with these measures. Awar MM, Walinsky P. Advanced cardiac life support: Reviewing recommendations from the AHA guidelines. Geriatrics 2003; 58(Nov):30-34.

- Abstract
An important gap in the literature is how clinicians feel about patient-centered technologies and how clinicians experience patient-centered technologies in their workflows. Our goal was to identify clinician users' perspectives on facilitators (pros) and barriers (cons) to using 1 digital texting innovation to promote family centered care during patients' hospitalizations. This qualitative study was conducted at a tertiary care center in Houston, consisting of 7 hospitals (1 academic hospital and 6 community hospitals), involving analyzation of 3 focus groups of 18 physicians, 5 advanced practice providers, and 10 nurse directors and managers, as well as a content analysis of 156 real-time alerts signaling family dissatisfaction on the nursing unit/floor. Thematic analysis methods were used. We selected these participants by attending their regularly scheduled service-line meetings. Clinician feedback from focus groups resulted in 3 themes as facilitators : (a) texting platforms must be integrated within the electronic medical record; (b) texting reduces outgoing phone calls; (c) texting reduces incoming family phone calls. Clinician feedback resulted in 3 themes as barriers : (a) best practice alerts can be disruptive; (b) real-time alerts can create hopelessness; and (c) scale-up is challenging. The analyzation of facilitators (pros) and barriers (cons) pertains only to the clinician's feedback. We also analyzed real-time alerts signaling family dissatisfaction (defined as "service recovery escalation" throughout this manuscript). The most common selection for the source of family dissatisfaction, as reflected through the real-time alerts was, "I haven't heard from physicians enough," appearing in 52 out of 156 alerts (33%). The second most common selection for the source of dissatisfaction was "perceived inconsistent or incomplete information provided by team members," which was selected in 48 cases (31%). Our findings indicate that clinicians value inpatient texting, not only for its ability to quickly relay updates to multiple family members with 1 click, but also because, when used intentionally and meaningfully, texting decreases family phone calls., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

- Abstract
While there is an evolving literature on the benefits of texting and patient-centered technologies, texting initiatives have not focused on family members. We sought to identify patients' family members' perspectives on facilitators and barriers to using 1 digital texting innovation to promote family-centered care during patients' hospitalizations. This qualitative study was conducted at a tertiary care center in Houston, consisting of 7 hospitals (1 academic hospital and 6 community hospitals), involving analyzation of 3137 comments from family members who used the digital texting technology. Thematic analysis methods were used. The data analysis for loved ones' feedback resulted in 4 themes as facilitators: (1) inpatient text messaging keeps loved ones updated and connected (n = 611); (2) inpatient text messaging allows for stronger continuity of communication (n = 69); (3) messaging promotes a sense of staff compassion and service (n = 245); and (4) messaging reduces phone calls (n = 65). The data analysis resulted in 4 themes as barriers to text messaging helpfulness: (1) messages could feel generic (n = 31); (2) inpatient texting was not needed if all loved ones were regularly at bedside (n = 6); (3) messages could have a perceived delay (n = 37); and (4) security features could impact convenience (n = 29). Our findings indicate that family members and loved ones value inpatient text messages, not only for the information the messages provide, but also because the act of writing text messages and preparing loved ones shows inclusiveness, compassion, and family-centered care., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

- Abstract
Background: Acute small bowel obstruction is a common surgical emergency usually caused by abdominal adhesions, followed by intraluminal tumors from metastatic disease. Although lymphomas have been known to cause bowel obstruction, Burkitt lymphoma is seldom reported to induce an obstruction in the adult population., Case Presentation: A 78-year-old Hispanic man with a history of abdominal interventions presented to our hospital with abdominal pain. Computed tomography revealed a partial small bowel obstruction attributed to local inflammation or adhesions. Medical management with bowel rest and nasogastric decompression resulted in resolution of symptoms and quick discharge. He returned 2 days later with worsening abdominal pain. Repeat imaging showed progression of the partial small bowel obstruction, but with an additional 1.6-cm nodular density abutting the anterior aspect of the gastric antrum and lobulated anterior gastric antral wall thickening. He was taken to the operating room, where several masses were found. Intraoperative frozen sections were consistent with lymphoma, and pathology later revealed Burkitt lymphoma. Disease was found on both sides of the diaphragm by positron emission tomography. After the initial resection and adjuvant chemotherapy, the patient is alive and well about 14 months after resection., Conclusions: Small bowel obstruction is uncommonly due to Burkitt lymphoma in the geriatric population and is more frequently seen in the pediatric and young adult populations. Burkitt lymphoma is very aggressive with rapid cell turnover leading to significant morbidity. The rapid recurrence of an acute abdominal process should prompt an investigation for a more sinister cause such as malignancy.

- Abstract
A 58-year-old male patient with incessant ventricular tachycardia was referred to cardiac magnetic resonance for scar assessment. He was found to have metastatic amelanotic melanoma of the heart. The cardiac magnetic resonance-based diagnosis of cardiac malignancy critically altered the subsequent clinical management. There was a marked response to immunotherapy as evidenced by follow-up imaging studies. ( Level of Difficulty: Intermediate. )., (© 2019 The Authors.)

- Abstract
Purpose: To compare costs of care and quality outcomes between teaching and nonteaching hospitalist services, while testing the assumption that resident-driven care is more expensive., Method: Records of inpatients with the top 20 Medicare Severity Diagnosis-Related Groups admitted to the University Teaching Service (UTS) and nonteaching hospitalist service (NTHS) at Houston Methodist Hospital from 2014-2015 were analyzed retrospectively. Direct costs of care, length of stay (LOS), in-hospital mortality (IHM), 30-day readmission rate (30DRR), and consultant utilization were compared between the UTS and NTHS. Propensity score matching and case mix index (CMI) were used to mitigate differences in baseline characteristics. To compare outcomes between matched groups, the Wilcoxon rank sum test and chi-square test were used. A sensitivity analysis was conducted using multivariable regression analysis., Results: From the overall study population of 8,457 patients, 1,041 UTS and 3,123 NTHS patients were matched. CMI was 1.07 for each group. The UTS had lower direct costs of care per case ($5,028 vs. $5,502, P = .006), lower LOS (4.7 vs. 5.2 days, P = .0002), and lower consultant utilization (1.0 vs. 1.6, P ≤ .0001) versus the NTHS. The UTS and NTHS 30DRR (17.2% vs. 19.3%, P = .110) and IHM (2.9% vs. 3.7%, P = .206) were comparable. The multivariable regression analysis validated the matched data and identified an incremental cost savings of $333/UTS patient., Conclusions: Patients of an academic hospitalist service had significantly shorter LOS, fewer consultants, and lower direct care costs than comparable patients of a nonteaching service.

- Abstract
Salt flats (sabkha) are a recognized habitat for microbial life in desert environments and as analogs of habitats for possible life on Mars. Here we report on the physical setting and microbiology of interdune sabkhas among the large dunes in the Rub' al Khali (the Empty Quarter) in Liwa Oasis, United Arab Emirates. The salt flats, composed of gypsum and halite, are moistened by relatively fresh ground water. The result is a salinity gradient that is inverted compared to most salt flat communities with the hypersaline layer at the top and freshwater layers below. We describe and characterize a rich photosynthetically-based microbial ecosystem that is protected from the arid outside environment by a translucent salt crust. Gases collected from sediments under shallow ponds in the sabkha contain methane in concentrations as high as 3400 ppm. The salt crust could preserve biomarkers and other evidence for life in the salt after it dries out. Chloride-filled depressions have been identified on Mars and although surface flow of water is unlikely on Mars today, ground water is possible. Such a near surface system with modern groundwater flowing under ancient salt deposits could be present on Mars and could be accessed by surface rovers.

- Abstract
Background: The Ministry of Public Health (MOPH) in Lebanon provides cancer drugs free of charge for uninsured patients who account for more than half the total caseload. Other categories of cancer care are subsidized under more stringent eligibility criteria. MOPH's large database offers an excellent opportunity to analyze the cost of cancer treatment in Lebanon., Materials and Methods: Using utilization and spending data accumulated at MOPH during 20082013, the cost to the public budget of cancer drugs was assessed per case and per drug type., Results: The average annual cost of cancer drugs was 6,475$ per patient. Total cancer drug costs were highest for breast cancer, followed by chronic myeloid leukemia (CML), colorectal cancer, lung cancer, and NonHodgkin's lymphoma (NHL), which together represented 74% of total MOPH cancer drug expenditure. The annual average cancer drug cost per case was highest for CML ($31,037), followed by NHL ($11,566). Trastuzumab represented 26% and Imatinib 15% of total MOPH cancer drug expenditure over six years., Conclusions: Sustained increase in cancer drug cost threatens the sustainability of MOPH coverage, so crucial for socially vulnerable citizens. To enhance the bargaining position with pharmaceutical firms for drug cost containment in a small market like Lebanon, drug price comparisons with neighboring countries which have already obtained lower prices may succeed in lowering drug costs.

- Abstract
IgM nephropathy is a relatively rare cause of idiopathic nephrotic syndrome.1 It was initially described by van de Putte,2 then by Cohen and Bhasin in 1978, as a distinctive feature of mesangial proliferative glomerulonephritis.2 It is typically characterized by diffuse IgM deposits on the glomeruli and diffuse mesangial hypercellularity. Little is known about the pathogenesis and treatment of this disease.1,3 We describe a patient who presented with nonspecific symptoms of epigastric pain, nausea, and early satiety. Abdominal imaging and endoscopies were unremarkable. She was found to have significant proteinuria (6.4 g/24 hours), hyperlipidemia, and edema consistent with a diagnosis of nephrotic syndrome. Kidney biopsy was performed and confirmed an IgM nephropathy. Less than 2 weeks after her diagnosis of IgM nephropathy, she presented with an acute cerebellar stroke. Thrombophilia is a well-known complication of nephrotic syndrome, but a review of the literature failed to show an association between IgM nephropathy and acute central nervous system thrombosis.

- Abstract
Background: Celiac disease (CD) is a complex autoimmune disorder that can lead to an inflammatory small intestinal villous atrophy and malabsorption. Hartnup disease is an autosomal recessive disorder caused by increased urinary excretion of neutral amino acids. Co-occurrence of Hartnup disease and CD is extremely rare with only a single case reported., Case Presentation: We report a 3-year girl with chronic diarrhea, Hypoalbuminemia and exfoliative erythema. She was diagnosed with celiac disease, which did not improve on gluten free diet. Hartnup disease was suspected and was confirmed by neutral aminoaciduria. Niacin was started and followed by dramatic improvement., Conclusion: Presence of Celiac and Hartnup disease in single individual is very rare. Complete nutritional assessment of refractory celiac patient can reveal underlying nutritional deficiency.

- Abstract
The Ministry of Labor (MOL) has submitted to the Council of Ministers a social security reform plan. The Ministry of Public Health (MOPH) considers that health financing should be dealt with as part of a more comprehensive health reform plan that falls under its prerogatives. While a virulent political discussion is taking place, major stakeholders' inputs are very limited and civil society is totally put away from the whole policy making process. The role of the media is restricted to reproducing political disputes, without meaningful substantive debate. This paper discusses health insurance reform from labor market as well as public health perspectives, and aims at launching a serious public debate on this crucial issue that touches the life of every citizen.

- Abstract
Objectives: The goal of this study was to assess the utility of topical lubrication to aid stent delivery in challenging anatomy and its effects on long-term clinical outcome., Background: Failed stent delivery is encountered in up to 5% of percutaneous coronary interventions (PCI)., Methods: The effectiveness of topically applied lubrication to facilitate stent delivery after failed stent placement was evaluated in 20 (2.5%) out of 813 consecutive patients undergoing PCI. Initial attempts at stent delivery failed despite balloon predilatation and use of moderate-to-stiff guidewires in all patients. The lubricious solution used was Rotaglide, a phospholipid emulsion originally designed to reduce catheter friction during rotational atherectomy. Following unsuccessful delivery, stents were removed from the guiding catheters, topically saturated with Rotaglide, and deployment immediately reattempted. Procedural efficacy and long-term clinical outcomes were assessed., Results: The study population included 20 patients aged 69 +/- 10 years, all of whom had complex lesions (ACC/AHA Class B(2) or C). Rotaglide lubricated stents were successfully deployed at the target lesions in 17 of the 20 patients (85%). Patients were followed 19.5 +/- 3.2 months after their index procedure. There were no periprocedural complications or subacute stent thromboses. Of the 14 patients with drug-eluting stents, none had clinical restenosis or target vessel revascularization. Target lesion revascularization secondary to restenosis was required in 1 of 3 patients treated with bare-metal stents., Conclusions: Topical lubrication is a simple and effective aid for stent delivery in complex lesions. Rotaglide appears safe and biocompatible with drug-eluting stents., ((c) 2006 Wiley-Liss, Inc.)

- Abstract
Objectives: The goal of this study was to evaluate the safety and efficacy of nicardipine in reversing no-reflow during percutaneous coronary intervention (PCI)., Background: No-reflow is a common complication of PCI in patients with acute coronary syndromes or venous bypass graft disease. Although nicardipine has an attractive pharmacological profile and has been used clinically to treat no-reflow, there is a paucity of published data regarding its effectiveness in this setting., Methods: We conducted a retrospective analysis of 72 consecutive patients who received intracoronary nicardipine to reverse no-reflow during coronary intervention. Qualitative TIMI flow grade and quantitative TIMI frame count methods were used to assess the efficacy of nicardipine., Results: A mean of 460 +/- 360 mcg of intracoronary nicardipine was used. No-reflow was successfully reversed with complete restoration of TIMI 3 flow in 71 of 72 patients (98.6%). TIMI flow grade improved from 1.65 +/- 0.53 prior to nicardipine to 2.97 +/- 0.24 after treatment (P < 0.001). TIMI frame count decreased from 57 +/- 40 at the time of no-reflow to 15 +/- 12 after nicardipine administration (P < 0.001). Nicardipine therapy was well tolerated without adverse hemodynamic or chronotropic effects., Conclusions: In this largest series to date, intracoronary nicardipine was demonstrated to be a safe and highly effective pharmacological agent to reverse no-reflow during PCI., ((c) 2006 Wiley-Liss, Inc.)

- Abstract
The World Health Report 2000 has been the subject of extensive debate. The authors highlight in the following, what they consider as major limitations that are either inherent to methods followed and the validity of data used, or related to the particular situation of Lebanon. This article tackles the first two of the set goals i.e. level of health and responsiveness as well as the overall system performance. The Report clearly states that extensive use has been made of estimates of indicators, and that there were often conflicting sources of information on these indicators. In the case of Lebanon, data was not available for most of the values used. In fact, the last national population census was conducted in 1932, and vital registration is incomplete. Therefore, one would question the value of the estimates, based on which the calculations were made for Lebanon, such as Life tables, and Causes of Deaths. Finally, the authors conclude that despite the critics, embarking in this exercise is useful for Lebanon, particularly at this stage, for monitoring the reform process in the health sector.

- Abstract
This paper intends to analyze the health care system in Lebanon from the organizational and financial points of view. It allows for an understanding of the health services' market by tackling it from different angles: supply versus demand, private versus public sectors, curative versus preventive services, hospital versus ambulatory care. This study necessitated a review of all previous surveys made in this field, during the after-war period. It also needed the daily collection and follow-up of pertinent data with all private and public agencies and concerned ministries, over a one-year period. In addition, a critical analysis has been made to the survey Conditions de vie des ménages, en 1997, that was carried out by the Central Administration of Statistics, that came to complete the missing data concerning household expenditures on insurance and health services. Especially that this survey covered the same period (1997), subject of this study. The paper reveals that, although the private sector is the main provider of both hospital and ambulatory care, private hospitals are flourishing on public money, whereas outpatients care is mainly financed by the households. Evidence shows that the Lebanese health care system succeeded in resolving the problem of accessibility to primary, secondary and tertiary health care, responding thus to the value of equity. But, at the price of an ever escalating cost, threatening the sustainability of the system. This is what is attained in this paper, as it shows clearly that expenditures on health have reached an alarming level of the GDP share. Our purpose being providing solid arguments in favor of reforming the health system.

- Abstract
Beas-Zarate and coworkers (Eur. J. Pharmacol., 198 (1991) 7-14) recently reported markedly reduced concentration of presynaptic serotonin neurotransmitter markers in cerebellum of rodents which had suffered destruction of the inferior olivary-cerebellar (climbing fibre) projections by the neurotoxin 3-acetylpyridine; these experimental animal data suggested that serotonin might be one of the neurotransmitters released by climbing fibres. We measured the concentration of serotonin and its major metabolite 5-hydroxyindoleacetic acid (5-HIAA) in autopsied cerebellar cortex of 14 patients with dominantly-inherited olivopontocerebellar atrophy (OPCA) who all had near-total degeneration of the inferior olivary climbing fibres. As compared with the controls, mean concentration of serotonin in cerebellar cortex of the OPCA patients was normal whereas 5-HIAA levels (+79%, P less than 0.02) and 'turnover' ratio 5-HIAA/serotonin (+148%, P less than 0.05), on average, were significantly elevated. These data do not support the notion that serotonin is a predominant neurotransmitter of the human climbing fibre. However, the markedly elevated serotonin turnover ratio suggests the possibility of increased serotonergic neuronal activity, which might alter, and perhaps improve, the functioning of the preserved cerebellar cortical neurones in OPCA.

- Abstract
We measured the levels of aspartate, glutamate, gamma-aminobutyric acid (GABA), and other amino acids in autopsied brain of 6 patients from one family (Pedigree S) with dominantly inherited olivopontocerebellar atrophy. A previous demonstration of reduced aspartate concentration in plasma of affected members of this family suggested the possibility of a generalized disorder of amino acid metabolism affecting the brain. As compared with the control levels, mean levels of aspartate and glutamate were markedly reduced by about 70 and 40%, respectively, in the degenerated cerebellar cortex from the patients. Since the cerebellar aspartate reduction likely exceeds the amount that could be explained by neuronal loss, other factors such as abnormal aspartate metabolism, neurotransmitter turnover, or both are probably involved. Mean aspartate, glutamate, and GABA levels were also reduced by about 10 to 30% in most of the 16 examined extracerebellar brain areas in which no or, at most, mild neuronal cell loss was observed by semiquantitative estimation. Concentrations of taurine, glutamine, and omicron-phosphoethanolamine were normal in all brain areas examined. Our biochemical data provide support to the presence of a generalized, but quantitatively mild, disturbance in amino acid metabolism in patients with olivopontocerebellar atrophy from Pedigree S. The regionally widespread amino acid reductions in the brain, of as yet unknown pathophysiological significance, could be due to a failure of one or more enzymes involved in aspartate and glutamate metabolism.

- Abstract
In order to characterize more completely the nature of the frontal lobe-type cognitive changes in patients with dominantly inherited olivopontocerebellar atrophy (OPCA) we administered two tasks sensitive to frontal system dysfunction, delayed alternation (DA) and delayed response (DR), to 12 patients from one OPCA family. Affected members from this family have previously been shown to have a marked and widespread cerebral (including frontal) cortical cholinergic reduction as severe as that observed in Alzheimer's disease. Performance on DA, but not on DR, was significantly impaired in the OPCA patients compared to that in the controls. We suggest that the DA deficits in OPCA could be a consequence of a loss of cholinergic innervation to orbitofrontal or possibly temporal cortical areas and/or damage to the integrity of the cerebello-frontal neuronal connections.

- Abstract
A cerebral cortical cholinergic reduction in dominantly inherited olivopontocerebellar atrophy (OPCA) was recently described. Although the magnitude of the cholinergic reduction was similar to that observed in Alzheimer's disease (AD), none of the OPCA patients was reported to have been demented. We now describe a comprehensive neuropsychological assessment of 11 patients from one of the OPCA pedigrees which we examined biochemically. Detailed neuropsychological testing disclosed previously unrecognized deficits in verbal and nonverbal intelligence, memory, and frontal system function which were positively correlated with the severity of cerebellar ataxia. However, our OPCA patients appeared to be at most only mildly disabled by their cognitive impairment and scored within or close to the normal range on a simple mental status screening examination. This, as well as an absence of any aphasia, apraxia, or agnosia, contrasts with the profile and severity observed in advanced AD dementia, characterized by a similar cortical cholinergic deficit. This finding also suggests that cholinergic reduction may explain only part of the pathophysiology underlying the dementia of AD.

- Abstract
We report two patients with dyskinesia responding to antidepressants. The first is a 70-year-old man with depression, Parkinsonism and neuroleptic-induced tardive dyskinesia who presented with hysterical mutism. After recovery from the mutism, he was started on desipramine for depression. One week later the dyskinesia improved markedly. The second patient is a 61-year-old man with Parkinson's disease, dementia, depression and L-dopa-induced oro-lingual-facial dyskinesias. He was taking levodopa, trihexyphenydil and bromocriptine. The depression was treated first with desipramine and later with trazodone. The dyskinesia improved significantly on both drugs. The response of the dyskinesias to antidepressant medication may be due to the fact that antidepressants decrease beta-adrenoreceptor sensitivity and density which in turn may result in a diminished release of dopamine since beta-adrenoceptors mediate the noradrenaline-stimulated release of dopamine.

- Abstract
The learning ability of 12 patients with Parkinson's disease (PD) was studied using a verbal paired-associate learning task, and was compared with that of ten patients with Alzheimer's Disease (AD) and 12 controls (NC). Overall, the PD patients performed significantly better than the AD patients but significantly worse than the NC subjects. Their performance was not related to their overall level of cognitive functioning as measured by the Mattis' Dementia Rating Scale, but was unequally distributed suggesting that the PD population actually consisted of more than one subgroup. A low error group performed like controls, while a high error group had a learning impairment comparable to that of AD patients. It is concluded that PD patients may have three patterns of neuropsychologic performance: some are unimpaired, some have "focal" abnormalities, and some have a generalized impairment of cognitive function.

- Abstract
We recently reported reduced activity of the cholinergic marker enzyme cholineacetyltransferase (ChAT) in several brain regions of patients with dominantly inherited olivopontocerebellar atrophy (OPCA). To document the regional extent of these changes we performed a comprehensive examination of the behavior of ChAT throughout both cerebral cortical and subcortical brain areas in 5 patients from one large OPCA pedigree. As compared with the controls, mean ChAT activities in OPCA were reduced by 39 to 72% in all (n = 27) cerebral cortical areas examined and in several thalamic subdivisions, caudate head, globus pallidus, red nucleus, and medial olfactory area. In contradistinction to findings in Alzheimer's disease (AD), mean ChAT levels in OPCA amygdala and hippocampal subdivisions were either normal or only mildly reduced. The lack of severe disabling dementia in our OPCA patients compared with AD patients having a similar cortical cholinergic reduction could be explained by an absence of either a marked cholinergic loss in amygdala or hippocampus or significant loss of noncholinergic cerebral cortical and limbic neurons as occurs in AD brain. We suggest that this and other OPCA pedigrees having a cortical cholinergic reduction represent a unique model for the study of behavioral consequences of a more selective cerebral cortical cholinergic lesion rather than a limbic cholinergic lesion.
