Background: Transthyretin (TTR), also known as prealbumin, has been suggested as an indicator of protein and nutritional status.
Objective: The aim of this study was to examine the maternal and umbilical cord (UC) TTR in relation to intrauterine growth, and the serum TTR of preterm infants in relation to nutritional status and growth.
Methods: After application of exclusion criteria, 49 preterm infants (mean gestational age and birth-weight 32.9±2.9 weeks and 1822±556 g) were included in the study. Transthyretin was sampled at birth and on days 14, 28 or at discharge with growth parameters and nutritional laboratories.
Results: Mean UC and maternal TTR were positively correlated (8.5±2.4 mg/dL and 20.4±7.0 mg/dL, r=0.31, P=0.07). Umbilical cord TTR was neither an index of maturity nor of intrauterine growth. Umbilical cord TTR was higher in females (9.4±2.6 versus 7.6±1.8 mg/dL, P=0.015). Maternal TTR was lower in twin pregnancies (16.8±4.9 versus 22.5±7.3 mg/dL, P=0.007). Although TTR levels gradually increased over time in correlation with post-menstrual and chronological ages (r=0.24, P=0.011 and r=0.40, P<0.001, respectively), there was no correlation to weight gain (r=0.10, P=0.41), nutritional status, protein intake, or laboratories. The only significant correlations were between TTR and glucose and triglycerides levels (r=0.51, P<0.001 for both).
Conclusions: Although TTR levels increased over time, we could not demonstrate significant correlations between TTR and indices of the nutritional status in preterm infants at birth or during the neonatal course.
External accreditation reviews of undergraduate medical curricula play an important role in their quality assurance. However, these reviews occur only at 4–10-year intervals and are not optimal for the immediate identification of problems related to teaching. Therefore, the Standards of Medical Education in Israel require medical schools to engage in continuous, ongoing monitoring of their teaching programs for
compliance with accreditation standards. In this paper, we propose the following: (1) this monitoring be assigned to independent medical education units (MEUs), rather than to an infrastructure of the dean’s office, and such MEUs to be part of the school governance and draw their authority from university institu¬tions; and (2) the differences in the importance of the accreditation standards be addressed by discerning between the “most important” standards that have been shown to improve student well-being and/or patient health outcomes; “important” standards associated with student learning and/or performance; “possibly important” standards with face validity or conflicting evidence for validity; and “least important” standards that may lead to undesirable consequences. According to this proposal, MEUs will evolve into entities dedicated to ongoing monitoring of the education program for compliance with accreditation standards, with an authority to implement interventions. Hopefully, this will provide MEUs and faculty with the common purpose of meeting accreditation requirements, and an agreed-upon prioritization of accreditation standards will improve their communication and recommendations to faculty.
Background and Objective: Postoperative (post-op) pain control has an important impact on post-op rehabilitation. The logistics of its maintenance challenge the effect of peripheral nerve block on post-op pain control, with the risk for post-op complications. We hypothesized that perioperative use of local infiltration analgesia (LIA) is comparable to post-op pain control by peripheral nerve block.
Materials and Methods: We evaluated three groups of patients treated with primary total knee arthroplasty (TKA) due to symptomatic end-stage osteoarthritis with post-op pain control by LIA (LIA group, n=52), femoral plus sciatic nerve block (FSNB) (FSNB group, n=54), and without local or regional analgesia as controls (Control group, n=53). The primary outcome variable was the post-op pain level intensity as measured by the visual analog scale (VAS). Secondary outcome variables were knee function measured by the Knee Society Score (KSS) and the quadriceps muscle strength recovery profile.
Results: Up to 4 hours post-op, pain intensity was significantly lower in FSNB patients (P<0.05). This effect of the peripheral nerve block on the pain level disappeared 6 hours post-op. The LIA and FSNB patients showed a significant decrease in pain intensity on days 2 and 3 post-op (P<0.05) with no mutual differences (P>0.05). This effect disappeared on day 4 post-op (P>0.05). The KSS score showed similar significant improvement of functional abilities (P<0.001) in all three groups. There was no difference in KSS scores among the groups 6 months after surgery (P>0.05). Quadriceps muscle recovery profile was similar in the LIA and Control groups, but significantly poorer in the FSNB group (P<0.001).
Conclusion: The value of very short-term and improved pain relief of post-op FSNB over LIA of the surgical wound should be carefully weighed against its cost, logistics, and potential complication threat.
Background and Objective: Medical cannabis is becoming an acceptable treatment modality in medicine, especially for pain relief. Concurrently, cannabis use is becoming more prevalent worldwide, a public demand-driven trend despite the lack of established scientific basis. This observational open-label study sought to investigate the effectiveness of cannabis therapy for alleviating low back pain symptoms.
Methods: Two types of cannabis treatment modalities were sequentially administered to chronic low back pain patients. After an initial 1-month washout period (WO1), the first modality was cannabidiol (CBD)-rich sublingual extract treatment administered for 10 months. Following another washout period, the second modality, Δ⁹-tetrahydrocannabinol (THC)-rich smoked inflorescence (whole dried cannabis flowers) was administered for 12 months.
Results: Enrolled in the study were 24 patients whose advanced imaging studies (i.e. computerized tomography or magnetic resonance imaging of the lumbar spine) revealed disc herniation or spinal stenosis. Three patients dropped out of extract therapy treatment but resumed study participation to receive THC-rich smoking therapy. After a minimum of 2 years, cannabis therapy had reduced lower back pain symptoms, as assessed by Oswestry Disability Index, the SF-12 patient-reported outcome questionnaire, and the visual analogue scale. Pain reduction was not significant during the extract treatment part of the study; however, pain reduction was significant during the inhaled therapy part of the study.
Conclusions: Our findings indicate that inhaled THC-rich therapy is more effective than CBD-rich sublingual extract therapy for treating low back pain and that cannabis therapy is safe and effective for chronic low back pain.
Objective: Cirrhotic cardiomyopathy (CCM) is associated with increased morbidity and mortality in patients with liver cirrhosis. Yet, it remains an under-diagnosed entity. Further, its relation to the severity of cirrhosis is contradictory. We conducted this study on an Indian population to determine the cardiac dysfunctions in cirrhosis of the liver and correlations with etiologies and cirrhosis severity.
Methods: This study enrolled patients with diagnosed liver cirrhosis without any cardiac disease or conditions affecting cardiac function. All participants were evaluated clinically, electrocardiographically, and echocardiographically. Cirrhosis severity was assessed by scores from the Model for End-stage Liver Disease (MELD) and Child–Turcotte–Pugh (CTP) tests. Cirrhotic cardiomyopathy was defined as diastolic dysfunction and/or systolic dysfunction with QT prolongation.
Results: Ninety-six patients were evaluated, and CTP-A stage of cirrhosis was found in 23 (24%), CTP-B in 42 (43.8%), and CTP-C in 31 (32.3%) cases. Systolic dysfunction was most frequent (P=0.014), and left ventricular ejection fraction was significantly reduced (P=0.001) in CTP-C stage of cirrhosis. Cirrhotic cardiomyopathy was found in 39.6% (n=38) of patients; CCM patients had significantly higher CTP scores (9.6±2.6 versus 8.3±2.3, P=0.012) as well as MELD scores (19.72±4.9 versus 17.41±4.1, P=0.015) in comparison to patients without CCM.
Conclusion: Cirrhotic cardiomyopathy has a positive relationship with the severity of cirrhosis. Systolic function declines with the severity of cirrhosis, and overt systolic dysfunction can be present, particularly in the advanced stage of cirrhosis of the liver.
Xenotransplantation represents a viable solution to meet the great need to provide organ donors at a time when there are not enough human organ donors. A lot of clinical studies have focused on using genetically engineered pigs as the prime source for organ transplantation. However, several religions, such as Judaism and Islam, have restrictions on the use of pigs for food or in business. In this article, we review the Jewish perspectives on xenotransplantation. Overall, the preservation of human life trumps most of the potential religious concerns associated with xenotransplantation. However, there are religious nuances related to xenotransplantation that are highlighted here, and that must be addressed by rabbinical scholars.
Objective: Starvation in early life can cause poor bone health and metabolic aberrations in bone minerals, leading to abnormal bone development. Holocaust survivors have been exposed to starvation and malnutrition before and during World War II. This paper aims to provide the current state of knowledge on the osteoporosis risk in Holocaust survivors and their descendants.
Methods: The PubMed and Scopus databases were searched. Papers that reported original data on the risk of osteoporosis in Holocaust survivors and in their offspring were included in the study.
Results: Ten studies were included in this review. The majority of studies were case-control ones (n=7) versus two self-reported and one longitudinal study. Despite the limited cohort numbers and the small number of studies in the literature, the data showed a potential increased risk of osteoporosis in Holocaust survivors and especially in their descendants.
Conclusions: The review of these studies showed a higher prevalence of osteoporosis among Holocaust survivors and their offspring. Knowledge of the trans-generational inheritance of osteoporosis in the descendants of Holocaust survivors should increase the awareness of primary care health workers on osteoporosis screening and early diagnosis and implementation of preventive measures, including adequate vitamin D and calcium supplementation, and pharmacological treatment.
There is a long history of starvation, including reports dated back to antiquity. Despite exceptional scientific developments, starvation still exists today. The medical aspects of starvation were well established in the twentieth century, particularly following studies related to the 1943–1944 Bengal famine in India and starved prisoners of war and survivors of World War 2. The refeeding of the starved victims provided disappointing results. Nevertheless, those studies eventually led to the development of a new branch of research in medicine and to the definition of what is now known as refeeding syndrome. This paper briefly reviews the history and groundwork that led to today’s understanding of starvation and refeeding, with a particular emphasis on the observations from studies on starved Holocaust survivors and prisoners of war after World War 2. The relevance of these studies for modern times is briefly discussed.
Pancytopenia is defined as a reduction in red blood cells, white blood cells, and platelets, and can pose as a diagnostic challenge due to the multitude of causes. Myxedema coma is the manifestation of severe untreated hypothyroidism. This case report presents a rare instance of myxedema coma-associated pancytopenia in a 53-year-old man with a history of untreated hypothyroidism. The patient presented with altered mental status and vital instability, and on further workup was found to have pancytopenia. During his hospital stay his symptomatic hypothyroidism was identified, and he was treated with intravenous levothyroxine, hydrocortisone, and supportive care. The patient’s clinical status improved gradually, with normalized blood counts upon discharge. This case underscores the significance of considering myxedema coma in the differential diagnosis of pancytopenia, especially in older patients with limited healthcare access. Increased awareness of this association can aid clinicians in timely diagnosis and management, preventing potential complications associated with untreated hypothyroidism.
Background and Objective: Chronic low back pain disability (CLBPD) is a syndrome that includes pain, disability, emotional impairments, and social problems. The study was conducted to examine the effect of an inpatient rehabilitation program on the performance of everyday life tasks (daily activities), and report on pain in CLBPD patients with primary activities of daily living (ADL) deficits.
Methods: In a retrospective cohort study, demographic and clinical data were retrieved from records of inpatients admitted consecutively to the program. Scores of the Spinal Pain Independence Measure (SPIM) and of changes in reported pain levels were used to assess improvement in the performance of daily activities and pain reduction. T-tests were used to assess the significance of score changes. Spearman’s correlations and analysis of variance were used to assess relationships of SPIM gain and affecting factors.
Results: Ninety-nine patients were included. Daily task performance improved in 71 patients (71.7%). The SPIM score increased from 48.7 (SD 16.3) at admission to the rehabilitation program to 57.8 (SD 12.5) at discharge (P<0.001). The SPIM score at admission negatively affected SPIM gain (P<0.001). The SPIM gain was significant for admission SPIM scores of 50 or lower (P<0.05), but differences in SPIM scores were not as noticeable for patients with admission SPIM scores above 50. Relief in pain was reported in 59 patients (59.6%) and was not associated with function.
Conclusions: The multidisciplinary rehabilitation program, which improved function and provided limited pain relief in inpatients with CLBPD primary ADL deficits, can be effective for the most severe CLBPD cases.
