Background: The Gaza–Israeli conflict poses challenges for unbiased reporting due to its complexity and media bias. We explored recent scientific publications to understand scholarly discourse and potential biases surrounding this longstanding geopolitical issue.

Objectives: To conduct a descriptive bibliometric analysis of PubMed articles regarding the recent Gaza–Israeli conflict.

Methods: We reviewed 1628 publications using keywords and medical subject headings (MeSH) terms related to Gaza, Hamas, and Israel. We focused on articles written in English. A team of researchers assessed inclusion criteria, resolving disagreements through a third researcher.

Results: Among 37 publications, Lancet, BMJ, and Nature were prominent journals. Authors from 12 countries contributed, with variety of publication types (46% correspondence, 32% news). Pro-Gaza perspectives dominated (43.2%), surpassing pro-Israel (21.6%) and neutral (35.1%) viewpoints. Pro-Gaza articles exhibited higher Altmetric scores, indicating increased social media impact. Pro-Israel publications were predominantly authored by Israelis.

Conclusions: The prevalence of pro-Gaza perspectives underscores challenges in maintaining impartiality. Higher social media impact for pro-Gaza publications emphasizes the need for nuanced examination. Addressing bias is crucial for a comprehensive understanding of this complex conflict and promoting balanced reporting.

Background: Implant-based breast reconstruction (IBR) is the most common method of reconstruction for breast cancer. Bacterial infection is a well-known risk with reported rates ranging from 1% to 43%. The most common pathogens of breast implant infection described in the literature are Staphylococcus aureus, Staphylococcus epidermidis, and coagulase-negative staphylococci. However, the prevalence of other pathogens and their antibiotic sensitivity profile differs profoundly in different parts of the world.

Objectives: To review the current literature and protocols with respect to our region and to determine a more accurate antibiotic protocol aimed at our specific local pathogens.

Methods: A retrospective review was conducted of all cases of clinically infected implant-based breast reconstruction in our institution from June 2013 to June 2019, as well as review of microbiologic data from around the world based on current literature.

Results: A total of 28 patients representing 28 clinically infected implant-based breast reconstruction were identified during the studied period. Thirteen patients (46.4%) had a positive bacterial culture growth, with P. aeruginosa being the most common microorganism identified (46.1%). Review of international microbiological data demonstrated significant variation at different places and time periods.

Conclusions: Microbiological data in cases of infected breast reconstructions should be collected and analyzed in every medical center and updated every few years due to the variations observed. These data will help to adjust the optimal empirical antibiotic regimens given to patients presenting with infections after breast reconstruction.

Background: Pain management is fundamental in the treatment of a trauma casualty. Adequate pain management is associated with decreased long-term morbidity and chronic pain. Nonetheless, pain is frequently not documented nor adequately treated in the prehospital setting, a phenomenon described as oligoanalgesia. Gender bias has been suggested as a risk factor for oligoanalgesia.

Objectives: To examine the association between casualty gender and pain management in the prehospital trauma setting.

Methods: We conducted a retrospective cohort study of the Israel Defense Forces Trauma Registry between 2015 and 2020. Univariable analysis followed by multivariable logistic regression was used to assess the association between casualty gender and pain management. For adult patients for whom gender was known, pain scores were documented.

Results: A total of 1044 casualties were included in the study; 894 (85.6%) were male. Females and males differed in several demographic and injury characteristics, including age in years (mean 36 vs. 27.6, P value < 0.001) and injury mechanism (16%% vs. 34.5% penetrating injury, P value < 0.001). Female casualties were less likely to be treated for pain (odds ratio [OR] 0.708, 95% confidence interval [95%CI] 0.5–1, P = 0.05). However, after adjustment for various factors, including pain severity, this association was insignificant (OR 0.748, 95%CI 0.46–1.23, P = 0.25).

Conclusions: In this prehospital study, gender bias in pain management was not apparent. As women’s role on the battlefield continues to increase, further studies regarding the role of

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by the progressive death of motor neurons leading to fatal paralysis. The causes of ALS remain unknown; however, evidence supports the presence of autoimmune mechanisms contributing to pathogenesis. Although several environmental factors have been proposed, the only established risk factors are older age, male gender, and a family history of ALS. To date, there are no diagnostic test for ALS, and clinicians rely on the combination of upper motor neuron and lower motor neuron signs in the same body region. The aim of this paper was to provide a comprehensive review of current clinical literature with special focus on the role of autoimmunity in ALS, differential diagnosis, and available therapeutic approaches. Current evidence suggests a contribution of the innate immune system in ALS, with a role of microglial cell activation at the sites of neurodegeneration. The median time from symptom onset to diagnosis of ALS is 14 months, and this time estimate is mainly based on specific clinical signs and exclusion of ALS-like conditions. Several therapeutic approaches have been proposed, including immunosuppressive drugs, to reduce disease progression. Riluzole has been established as the only, although modestly effective, disease modifying therapy, extending mean patient survival by 3to 6 months. Recent advances in understanding the pathophysiology mechanisms of ALS encourage realistic hope for new treatment approaches. To date, the cornerstones of the management of patients with ALS are focused on symptom control, maintaining quality of life and improving survival.

Attention deficit hyperactivity disorder (ADHD) is among the most prevalent chronic health disorders affecting school-age children. The disorder is the subject of much debate for several reasons, the major one being the diagnostic process, which in some aspects is unstructured and can be relatively easily biased. The impact of undiagnosed or misdiagnosed ADHD on the lives of many children can be severe. Therefore, it is important to understand the complexities of the diagnostic procedure in ADHD, including the cultural bias effect, the limitations of the DSM-IV-TR definitions, the effect of comorbid conditions on the diagnostic process, the gene-environment interactions, and the need to compose an objective, more accurate, and generally accepted diagnostic battery of tests. This review addresses the diagnostic difficulties of ADHD and considers some steps that would make ADHD a more easily identifiable disorder.

Background: Medication errors are a common cause of morbidity and mortality.

Objectives: To evaluate the rate of acknowledgment of medication errors as reported by physicians working in the community and in hospitals.

Methods: An anonymous questionnaire was sent to 9320 active physicians (about 48% community physicians, 17% hospital physicians and 35% working in both places), with questions on the rate and type of medication errors that they had encountered during their professional career. The questions specified errors in dosage, type of medicine (wrong indication), route of administration and drug interactions.

Results: Only 627 physicians (6.7%) responded. Of these, nearly 79% admitted having made an error in prescribing medication; the majority admitted to more than one error. Physicians with fewer years of experience admitted having made a mistake more than did physicians with more experience (P = 0.019). Pediatricians and geriatricians made more dosage mistakes (P = 0.02), while family physicians and psychiatrists made more mistakes in drug interactions (P = 0.001).

Conclusions: It is possible that indifference, fear of identification, or lack of awareness may have contributed to the low response rate despite the fact that the questionnaire was anonymous. Educational programs should be implemented in medical schools to encourage physicians to report errors before the onset of adverse reactions.

 Background: A publication bias exists towards positive results in studies funded by pharmaceutical companies.

Objectives: To determine whether drug studies in the pulmonary/allergy literature also demonstrate a publication bias towards more favorable results when a pharmaceutical company funds the study.

Methods: We reviewed all original articles published in seven pulmonary and allergy journals between October 2002 and September 2003. Included in the review were studies of inhaled corticosteroids (oral or nasal), long- or short-acting bronchodilators, or leukotriene receptor antagonists. Articles with funding from a pharmaceutical company and/or one or more authors employed by a pharmaceutical company were considered pharmaceutical company-sponsored studies. The remaining studies were considered not sponsored by a pharmaceutical company. Results were compared to ascertain whether positive results were obtained more frequently in the company-sponsored studies.

Results: Of the 100 articles included in this review 63 were considered pharmaceutical company-sponsored research. Results favorable for the drugs studies were significantly more common in those funded by a pharmaceutical company (98% vs. 32%).

Conclusions: In the pulmonary and allergy literature, as in other fields, there is a publication bias towards positive results in pharmaceutical company-sponsored research.

Background: Multiple sclerosis is a chronic demyelinating disease of the central nervous system that presents with variable signs and symptoms. This variability in the clinical presentation may result in misdiagnosis, unnecessary referrals and misleading information to the patients.

Objectives: To identify the types of misdiagnoses made on the presentation of MS.

Methods: Fifty consecutive MS patients were questioned on their early symptoms, their mental status, the disease course until the diagnosis was confirmed, and the different diagnoses they received.

Results: The patients had been referred to 2.2 ± 1.3 specialists before seeing a neurologist, and learned about their disease 3.5 years after the onset of symptoms. Twenty-nine patients (58%) were initially given 41 wrong diagnoses. While the majority of women were misdiagnosed mentally, orthopedic work-up was offered to the men. Misdiagnosis of MS occurred most often in patients who presented with non-specific sensory symptoms that did not conform to a specific neurologic syndrome. The patients emphasized the fact that not knowing worsened their anxiety, whereas receiving the diagnosis enabled them to begin coping with their disease.

Conclusions: MS is often overlooked when patients present with non-specific sensory complaints. The difference in type of misdiagnosis between men and women may reflect a gender-dependent bias in the way physicians interpret sensory complaints.
