Background: Early thyroid cancers have excellent long-term outcomes, yet the word “cancer” draws unnecessary apprehension. This study aimed to define when the recommendations for observation and surveillance may be extended to early thyroid cancers at the population level.
Methods: Non-metastasized thyroid cancers ≤40 mm diameter were identified from the 1975–2016 Surveillance, Epidemiology and End Results (SEER) database. Causes of death were compared across demographic data. Disease-specific outcomes were compared to the age-adjusted healthy United States (US) population. Survival estimates were computed using Kaplan–Meier and compared using the Cox proportional hazard model. Dynamic benchmarks impacting disease-specific overall survival were determined by decision tree modeling and tested by the Cox model.
Results: Of the 28,728 thyroid cancers included in this study, 98.4% underwent some form of thyroid-specific treatment and were followed for a maximum of 10.9 years. This group had a 4.3% mortality rate at the end of follow-up (10.9 years maximum), with 13 times more deaths attributed to competing risks rather than thyroid cancer (stage T1a versus stage T1b, P=1.000; T1 versus T2, P<0.001). Among the untreated T1a or T1b tumors, the risk of disease-specific death was 21 times lower than death due to other causes. There was no significant difference between T1a and T1b tumors nor across sex. The age-adjusted risk of death for the healthy US population was higher than the population with thyroid cancer. Dynamic categorization demonstrated worsening outcomes up to 73 years, uninfluenced by sex or tumor size. For patients over 73 years of age, only tumors >26 mm impacted outcomes.
Conclusion: Based on the current data, T1a and T1b nodules have similar survival outcomes and are not significantly impacted even when left untreated. Multi-institutional prospective studies are needed to confirm these findings so that current observation and surveillance recommendations can be extended to certain T1 thyroid nodules.
There is universal agreement that the Nobel Prizes, given to individuals who have made an extraordinarily notable contribution to humankind in the fields of chemistry, physics, physiology or medicine, literature, and peace, are the most prestigious prizes offered for human achievement. This commentary gives an overview of the basis for Alfred Nobel writing his third will that established the five prizes and includes a discussion of why those five fields were chosen. The commentary includes factors that influenced his choices and contains examples of controversial selections or omissions, especially in the earlier years. A few were errors of omission (e.g. Tolstoy, Tesla, Edison, Best, Gandhi, Franklin), some errors of commission (e.g. Fibiger, Moniz); but, given the complexity of the task, the error rate is small. In some cases, the conclusion that an error had been made is debatable. Such decisions are difficult. Arne Tiselius, a Nobel laureate in chemistry and President of the Nobel Foundation said that one cannot in practice apply the principle that the Nobel Prize should be given to the person who is best; it is impossible to define who is best. Hence, there is only one alternative: to try to find a particularly worthy candidate. This paper includes a brief review of the integration of the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, established in 1968, and added to the original five Nobel Prizes; the prize was first awarded in 1969. A short discussion on the absence of a Nobel Prize in mathematics is provided. Adaptations to the development of “big” science, especially in physics, may require the Nobel Foundation to extend its limit of no more than three awardees for the prize in physics and, perhaps, other scientific disciplines.
The Joles Jewish Hospital in Haarlem (a small city in the Netherlands) was established in 1930 to provide a Jewish milieu for local patients. Mozes Joles, a wealthy Jewish businessman, bequeathed his fortune to the Haarlem Jewish community to accomplish this objective, and its spiritual leader, Rabbi Simon Philip de Vries, was the driving force in successfully achieving this goal. The Joles Hospital was forcibly closed by the Nazis in 1943, and the postwar leadership of the Haarlem Jewish community decided not to reopen it. Instead, they used the Joles inheritance to build old age homes in both Haifa, Israel, and Haarlem, thus ensuring a Jewish environment for elderly care in both locales. The realization of one man’s charitable act bettered the lives of both ill and elderly individuals.
Bite mark analysis plays a pivotal role in forensic investigations, by helping to identify suspects and establish links between individuals and crime scenes. However, traditional bite mark methodologies face significant challenges due to issues with reliability and subjectivity. Recent advances in microbiome analysis, which involves identifying and characterizing the microbial communities found in bite marks, have led to the emergence of a promising tool for forensic investigations. The integration of microbiome analysis with conventional DNA profiling enables more accurate interpretation of bite mark evidence in forensic investigations. This review provides an in-depth look at the integration of bite mark microbiome analysis with forensic DNA profiling. It also addresses the challenges and strategies involved in microbiome-based bite mark analysis for forensic purposes.
In December 2019, the first cases of a new contagious disease were diagnosed in the city of Wuhan, the capital of Hubei province in China. Within a short period of time the outbreak developed exponentially into a pandemic that infected millions of people, with a global death toll of more than 500,000 during its first 6 months. Eventually, the novel disease was named coronavirus disease 2019 (COVID-19), and the new virus was identified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Similar to all known pandemics throughout history, COVID-19 has been accompanied by a large degree of fear, anxiety, uncertainty, and economic disaster worldwide. Despite multiple publications and increasing knowledge regarding the biological secrets of SARS-CoV-2, as of the writing of this paper, there is neither an approved vaccine nor medication to prevent infection or cure for this highly infectious disease. Past pandemics were caused by a wide range of microbes, primarily viruses, but also bacteria. Characteristically, a significant proportion of them originated in different animal species (zoonoses). Since an understanding of the microbial cause of these diseases was unveiled relatively late in human history, past pandemics were often attributed to strange causes including punishment from God, demonic activity, or volatile unspecified substances. Although a high case fatality ratio was common to all pandemic diseases, some striking clinical character¬istics of each disease allowed contemporaneous people to clinically diagnose the infection despite null microbiological information. In comparison to past pandemics, SARS-CoV-2 has tricky and complex mech¬anisms that have facilitated its rapid and catastrophic spread worldwide.
On May 19, 2020, data confirmed that coronavirus 2019 disease (COVID-19) had spread worldwide, with more than 4.7 million infected people and more than 316,000 deaths. In this article, we carry out a comparison of the methods to calculate and forecast the growth of the pandemic using two statistical models: the autoregressive integrated moving average (ARIMA) and the Gompertz function growth model. The countries that have been chosen to verify the usefulness of these models are Austria, Switzerland, and Israel, which have a similar number of habitants. The investigation to check the accuracy of the models was carried out using data on confirmed, non-asymptomatic cases and confirmed deaths from the period February 21–May 19, 2020. We use the root mean squared error (RMSE), the mean absolute percentage error (MAPE), and the regression coefficient index R2 to check the accuracy of the models. The experimental results provide promising adjustment errors for both models (R2>0.99), with the ARIMA model being the best for infec¬tions and the Gompertz best for mortality. It has also been verified that countries are affected differently, which may be due to external factors that are difficult to measure quantitatively. These models provide a fast and effective system to check the growth of pandemics that can be useful for health systems and politi¬cians so that appropriate measures are taken and countries’ health care systems do not collapse.
Introduction: Antisemitism and antisemitic incidents have been increasing in United States medical institutions since the Hamas attack of October 7, 2023. Such incidents include anecdotal reports of antisemitic displays at medical school commencements. This study examined unprofessional behavior observed at the commencement ceremonies of the 25 US medical schools top-ranked for research excellence. This issue is significant since these graduates are expected to become future leaders in the field of medicine.
Materials and Methods: Based on publicly available videotaped commencements, we assessed the number of students in the graduating classes wearing non-school-provided regalia, carrying signs, wearing protest buttons, or engaging in verbal protests related to the Israel–terror groups conflict that were either openly antisemitic or potentially offensive or insensitive.
Results: Symbols representing antisemitic themes (keffiyehs and three-part graduation stoles conveying antisemitic messages) were worn by students at just under half (12) of the medical schools. The mean number of students in each school wearing keffiyehs or non-official school stoles was 4.0 (95% confidence interval [CI] 2.2–5.8), ranging from 0%–13% of the classes, or 2.5% of the overall graduating cohort. The wearing of buttons, carrying of banners or signs, verbal protests interrupting the ceremony, or students deviating from script ranged from 0% to 22.5% of graduating students, with a mean of 2.7 per school (95% CI -0.8–6.2), or 1.7% of the medical schools graduating cohort.
Conclusions: We identified unprofessional behavior at commencements of top-ranked medical schools consisting of antisemitism and displaying offensive and insensitive symbols and messaging. There is an urgent need for medical schools in the US to educate medical trainees about the dangers of antisemitism and all forms of hate and insensitivity.
Pain medicine in Israel and in the world has reached a crisis. The lack of available pain medicine services is resulting in the unsatisfactory treatment for chronic pain sufferers. The main causes of this crisis are: 1) the high prevalence of chronic pain, reaching levels of 17% in the adult population;2) the lack of appropriate training of primary care physicians in the field of chronic pain management; and 3) the paucity of consultation services in the field of chronic pain.
In this journal article, we propose a possible model for the solution of the problem, based upon levels of treatment according to the severity of the disease and upon training of primary and secondary care physicians in the treatment of pain. According to the model, the vast majority of treatment and management will take place in the community after appropriate training of primary care physicians. More complex cases will be referred to secondary care community-based pain clinics manned by physicians with further in-depth training. Only the most complex of patients, or those needing specialized treatment such as invasive analgesic therapy, will be referred to tertiary pain centers manned by specialists in pain medicine.
Implementation of this model will necessitate training of primary care physicians and the establishment of secondary care facilities and can, in our opinion, pose a pragmatic solution for the hundreds of thousands of patients suffering from chronic pain.
The world is facing an epidemic rise in diabetes mellitus (DM) incidence, which is challenging health funders, health systems, clinicians, and patients to understand and respond to a flood of research and knowledge. Evidence-based guidelines provide uniform management recommendations for “average” patients that rarely take into account individual variation in susceptibility to DM, to its complications, and responses to pharmacological and lifestyle interventions. Personalized medicine combines bioinformatics with genomic, proteomic, metabolomic, pharmacogenomic (“omics”) and other new technologies to explore pathophysiology and to characterize more precisely an individual’s risk for disease, as well as response to interventions. In this review we will introduce readers to personalized medicine as applied to DM, in particular the use of clinical, genetic, metabolic, and other markers of risk for DM and its chronic microvascular and macrovascular complications, as well as insights into variations in response to and tolerance of commonly used medications, dietary changes, and exercise. These advances in “omic” information and techniques also provide clues to potential pathophysiological mechanisms underlying DM and its complications.
Objectives: There are only sporadic reports on the clinical behavior and appropriate treatment of anaplastic seminoma. This retrospective study summarizes our experience with the anaplastic variant of classical (typical) seminoma.
Methods: Between 1986 and 2006, seven anaplastic seminoma patients were staged and treated at the Northern Israel Oncology Center. Staging procedures included meticulous physical and neurological examinations, complete blood count, full biochemistry profile, specific tumor markers, testicular ultrasound, and other radiological measures. All patients underwent inguinal orchiectomy and were staged properly. Six patients had stage I disease, and one patient had stage IIA disease. Patients were irradiated with doses ranging from 2,500 to 3,000 cGy, and the stage IIA patient received an additional 1,000 cGy boost to radiographically involved lymph nodes.
Results: After a mean follow-up of 11 years, six patients are alive with no evidence of disease. One patient died due to an unknown, non-oncological, cause, unrelated to his previous testicular tumor, while in complete remission.
Conclusions: Despite the low patient numbers and the retrospective nature of our study, it can be concluded that radiotherapy treatment for early-stage anaplastic seminoma patients might achieve the same excellent survival as for classical seminoma. However, the general consensus achieved through large-scale studies suggests that active surveillance should be offered to all stage I seminoma patients, regardless of the pathologic variant.
