The comprehension of a long-term humoral immune response against SARS-CoV-2 can shed light on the treatment and vaccination strategies of COVID-19 disease, improving the knowledge about this virus infection and/or re-infection. We assessed the IgG antibodies against SARS-CoV-2 nucleocapsid (N) protein (anti-SARS-CoV-2 (N) IgG) in 1441 COVID-19 convalescent patients within 15 months longitudinal study from middle-developed country. The main inclusion criteria was positive RT– PCR result on nasopharyngeal swab samples at least one month before antibody testing and absence of any induced or inherited immunodeficiency. 92.7% of convalescent patients’ serum contained anti-SARS-CoV-2 (N) IgG and only 1.3% of patients had a delayed antibody response. In the majority of convalescent patients’ the durability of antibodies lasted more than one year. The kinetics of anti-SARS-CoV-2 (N) IgG took a bell-shaped character—increased first 25–30 weeks, then started to decrease, but were still detectable for more than 15 months. We found that on the one hand anti-SARS-CoV-2 humoral response level correlates with disease severity, on the other, in particular, the level of peak antibodies correlates with age—older patients develop more robust humoral response regardless of sex, disease severity and BMI.

The recently detected virus in eastern China in 2018 led to some health concerns, especially with the global trend of spreading viruses. As a new RNA-detected genus of the henipavirus family was found in Eastern China, the number of patients affected has reached 35 through zoonotic spread, with symptoms ranging from simple fever to fatal affection of vital organs such as the brain, liver, and kidneys. Researchers have found that shrew animals might be a potential reservoir for the Langya virus; however, data is still limited regarding human-to-human transmission. Current efforts by the Chinese Health Ministry and the Taiwan Centers for Disease Control and Prevention to deduct the spread of the virus and track its origin by trying to sequence the disease genome are evident. With all this in mind, the recommendation to face this new novel virus revolves around protecting the most vulnerable population at risk of being infected, such as farmers, and preventing the spread of the virus. Efforts must be directed toward screening animals for henipavirus and diving more deeply into the etiology of how this virus has spread to humans to help understand the spread of zoonotic viruses in the future.

Lung cancer can present with unilateral atypical facial pain, a rare symptom due to vagus nerve involvement or paraneoplastic syndrome. This manifestation is usually missed, delaying the diagnosis and prognosis. We discuss a case of a 45-year-old male who presented with right-sided hemifacial pain and with normal neurological investigations.

The mammalian target of rapamycin (mTOR) is an important molecular regulator of cell growth and proliferation. Brain mTOR activity plays a crucial role in synaptic plasticity, cell development, migration and proliferation, as well as memory storage, protein synthesis, autophagy, ion channel expression and axonal regeneration. Aberrant mTOR signaling causes a diverse group of neurological disorders, termed ‘mTORopathies’. Typically arising from mutations within the mTOR signaling pathway, these disorders are characterized by cortical malformations and other neuromorphological abnormalities that usually co-occur with severe, often treatment-resistant, epilepsy. Here, we discuss recent advances and current challenges in developing experimental models of mTOR-dependent epilepsy and other related mTORopathies, including using zebrafish models for studying these disorders, as well as outline future directions of research in this field.

Introduction and Importance: Primary sclerosing encapsulating peritonitis (SEP), commonly known as abdominal cocoon syndrome (ACS), is considered to be one of the rare causes of intestinal obstruction. This syndrome is characterized by the formation of a fibrous-collagenous membrane that encapsulates the intestine and other abdominal organs. Several theories have been proposed to explain the disease’s etiology. Patients often present with symptoms of partial intestinal obstruction, which is challenging to diagnose before laparotomy. Of all the available investigations, the contrast-enhanced computed tomography of the abdomen is the most sensitive, showing a sac-like fibrous membrane covering the bowel loops along with the fluid collection. Definitive treatment includes excision and adhesiolysis. Case Presentation: We present a case report of ACS in a 30-year-old male patient. Clinical Findings and Investigations: The patient presented with a chronic history of progressive colicky abdominal pain associated with nausea, vomiting, constipation, and weight loss. Interventions and Outcome: Multiple investigations, including abdominal X-rays, ultrasound, and upper GI endoscopy, were unremarkable. However, the contrast-enhanced computed tomography abdomen suggested small bowel obstruction with a differential diagnosis of SEP. Later explorative laparotomy and histopathological examination confirmed the diagnosis of ACS. Adhesiolysis was performed intraoperatively, which resolved the patient’s symptoms. The patient was asymptomatic at the 6th month follow-up visit. Relevance and Impact: Being a fairly rare condition, primary SEP can lead to a plethora of misdiagnoses and discomfort to the patient if not diagnosed on time. This case report aims to create awareness of this disease outside of the expected demographics- perimenarchal Asian girls. It is highly important for this unusual case to serve as an educative tool for physicians all over the world.
