Constitutional symptoms of primary myelofibrosis can mask COVID-19 infection. We present the case of a patient with primary myelofibrosis on ruxolitinib who tested positive for COVID-19 as part of Hematopoietic Stem Cell Transplant (HSCT) workup. The patient was asymptomatic and took over four weeks to develop a negative COVID-19 RT-PCR test. She did not test positive for COVID-19antibodies.

Carmen Cámara Hijón, PhD – Usefulness of Cytokine Measurement to Support Decision-Making in Patients with COVID-19
The correct characterization of the immune response induced by SARS-Cov-2 includes the pattern of cytokines in peripheral blood. Dr. Carmen Camara discusses how assaying cytokine profiles allows us not only to establish a cause-effect relationship in unusual conditions (e.g. chiblain lesions and COVID-19) but even to make therapeutic decisions in some of them (e.g. pediatric multisystemic inflammatory syndrome).
She also describes a fast and cost-efficient method of measuring the cellular response induced by vaccines by measuring IFN-γ and IL-2 after whole-blood overnight stimulation with SARS-CoV-2 peptides, to identify the correlate of immunity in patients at risk, such as those with primary immunodeficiencies.
Martina Fabris, MD – Cytokines and COVID-19: The Value in Risk Stratification Within the First 72 Hours of Hospitalization
It is increasingly clear that the immune response to COVID-19, and not the pathogen itself, is responsible for the exaggerated release of inflammatory molecules during infection. Several cytokines play a key role in SARS-CoV-2 pathogenesis and can help to identify patients with worse prognosis or in a different phase of the pathological process. However, these cytokines can be difficult to assay, and we do not yet understand their relationship with classic inflammatory markers like CRP.
Dr. Martina Fabris discusses which cytokines, alongside standard markers of systemic inflammation, are most valuable in identifying patients at a high risk of an unfavorable outcome, and on the other hand, low-risk patients who can reasonably be discharged from the hospital. She also describes the challenge of using these new biomarkers effectively in daily clinical practice to support complicated diagnoses, to evaluate risk more effectively, and to ensure increasingly targeted therapies.

Interleukin16 and Interleukin 28B Genes Polymorphism in HBV Infected Saudi pa...iosrjce
The course of hepatitis B virus (HBV) infection is variable depending on many factors. In this study,
we investigated single nucleotide polymorphisms of interleukin-28B and interleukin-16 as possible host factors
which may determine the occurrence of hepatocellular carcinoma (HCC) in Saudi patients. Chronic hepatitis B
(CHB) patients (75), HCC patients (42), and healthy controls (70) were analyzed for polymorphisms of the IL16
and IL28B genes using PCR and restriction fragment length polymorphism (RFLP). Results showed that HCC
and chronic HBV patients had higher prevalence of rs11556218TG genotype than controls. The rs11556218GG
genotype was higher among HCC (14.4%) compared to chronic HBV (2.7%) patients. The IL-16 genotype
rs4072111CT was higher among HCC (47.6%) and chronic HBV (46.7%) patients than controls (28.6%). The
rs4072111TT genotype was higher among HCC patients compared to the other two groups. The T allele
frequency was higher among HCC patients than controls. The CT and TT of the IL-28B rs12979860 genotype
were significantly less frequent in chronic HBV and HCC patients. The IL-28B rs8099917 TG genotype was
more frequent among HCC (19%) compared to chronic HBV (8%) patients. However, no significant difference
was detected in the allele distribution.

Case report: in this manuscript, we report a case with ocular involvement in a male immunocompetent patient. He had extended skin lesions and conjunctival hyperemia on the right eye. After the laboratorial investigation we confirmed syphilis and excluded human immunodeficiency virus (HIV) infection. Considering he had uveitis, the case was conducted as neurosyphilis.and the treatment was made with Ceftriaxone, followed by excellent clinical response.
Conclusion: given the increasing number of cases of syphilis, in patients with polymorphic skin lesions associated with systemic
symptoms, it is important to exclude immunosuppression and even in immunocompetent.subjects this condition should always be a differential diagnosis.

The impact of the SARS-CoV-2 infection in all areas at the national and international level is undeniable, the aftermath of this “tornado” will be visible for a long time, even when the infection manages to be controlled. Two aspects of great interest to those of us who work in the area of oncology must be considered: on the one hand, the need to contain and control the devastating effects of the disease forced a reorganization in the operation of services, giving priority to COVID, conversion of medical units to hospitals COVID created a high-risk scenario for patients with other types of pathologies; This reorganization includes the allocation of large amounts of budget to COVID areas to the detriment of patients with other types of equally serious diseases - such as cancer, among others - who cannot wait for care in better times.

Uterine Myoma, Risk Factor and Pathophysiology: A Review ArticleAnonIshanvi
Uterine myoma is a benign neoplasm composed of uterine smooth muscle and connective tissue that supports it and is often referred to as fibromyoma, leiomyoma, fibroids. Can be single or multiple and reach large sizes (100 pounds). It has a tough consistency, with a clear cap boundary so that it can be removed from the surroundings. Uterine myoma, also known as leiomyoma or fibroid is a benign tumor that is often found in women of reproductive age (20-25%). At age> 35 years the incidence is higher, that is, closer to 40%. The high incidence of uterine myomas between the ages of 35 and the ages of 50 indicates a relationship between the incidence of uterine myomas and estrogen.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.

1. Abstract
Constitutional symptoms of primary myelofibrosis can mask COVID-19 infection. We present the
case of a patient with primary myelofibrosis on ruxolitinib who tested positive for COVID-19 as
part of Hematopoietic Stem Cell Transplant (HSCT) workup. The patient was asymptomatic and
took over four weeks to develop a negative COVID-19 RT-PCR test. She did not test positive for
COVID-19 antibodies. Patients with hematologic malignancies such as primary myelofibrosis or pa-
tients taking immunosuppressive therapy, such as ruxolitinib, may not develop infectious symptoms
from COVID-19. In addition, they may take longer to test negative and may not develop antibodies
to COVID-19. Therefore, these patients may be more vulnerable to re-infection. Although ruxoli-
tinib may contribute to immunosuppression and increased susceptibility to infection, the drug is
being studied as a possible treatment for COVID-19. To improve safety and patient outcomes, it
is critical to test patients for COVID-19 prior to HSCT as clinicians cannot rely on symptoms to
determine infection.
3. Introduction
Primary Myelofibrosis (MF) is a clonal myeloproliferative neo-
plasm which presents with anemia, splenomegaly, and constitu-
tional symptoms, including severe fatigue and fever [1]. The exact
molecular mechanism of MF pathogenesis is not known [2]. This
include the envelope, nucleocapsid, RNA-dependent RNA
polymerase, non-structural protein 10, and non-structural protein 14
and exoribonuclease [7]. In the bone marrow, clonal proliferation of
hematopoietic stem cells is thought to result in cytokine release,
myeloid hyperproliferation, and bone marrow fibrosis [3]. Driver
mutations of genes including JAK2, CALR, and MPL have been
identified [3]. The only cura- tive treatment is hematopoietic stem
cell transplant (HSCT) [1]. The mutation-enhanced international
prognostic score system for transplantation-age patients
(MIPSS70) provides risk stratifi- cation to identify appropriate
candidates for HSCT, which carries its own significant morbidity
[4]. Once a patient is identified for transplant, an extensive
examination, including infectiousworkup, should be pursued.
In the new age of Coronavirus disease 2019 (COVID-19), it is more
important than ever to determine if a patient has an infection prior
to cancer directed therapy, especially prior to HSCT. COVID-19 is
a novel viral respiratory infection that has rapidly caused a glob-
al pandemic. The infection has variable presentations in different
hosts. Up to 40-45% of COVID-19 cases may be asymptomatic [5].
However,classic symptoms include fever, cough, and dyspnea, an-

osmia, and diarrhea [6].
COVID-19 infection can be diagnosed by reverse transcription
polymerase chain reaction (RT-PCR) as well as point-of-care
(POC) antigen detection. There are various possible RT-PCR tar-
gets in the viral genome, which contains approximately 30,000 nu-
cleotides and 15 genes [7]. These include the envelope, nucleocap-
sid, RNA-dependent RNA polymerase, non-structural protein 10,
and non-structural protein 14, exoribonuclease [7]. Mutations and
variations in the sequence can limit this method [7]. Point-of care
testing is less sensitive than the RT-PCR, and a negative RT-PCR
result does not exclude COVID-19 infection[7].
In addition to initial testing for COVID-19, antibody assays have
been developed to detect the immune response to infection. One
study of 285 subjects showed 100% of patients tested positive for
antiviral immunoglobin G (IgG) within 19 days of symptom on-
set [8]. In addition, 7 of 148 close contacts of COVID-19 patients
with initial negative RT-PCR tests were found to have positive IgG
and/or immunoglobin M (IgM) antibodies [8]. Another study in
Wuhan, China found 55 of 66 confirmed COVID-19 cases to test
positive for IgG antibodies[9].
We present the case of a patient with primary MF who was inciden-
tally diagnosed with COVID-19 prior to stem cell transplant and
her lack of ability to mount an immuneresponse.

3. Volume4 Issue 10 -2020 Case Report
Our patient was chronically treated with the Janus kinase inhibitor
(JAKi) ruxolitinib, and this was continued during COVID-19 in-
fection. The use of ruxolitinib in MF is well established with bene-
fits related to symptoms and overall survival [10]. However,there is
also a possibility of increased infectious risk with this immunosup-
pressive treatment due to effects on cytokine release, T-cells, and
natural killer cells [11]. This is complicated by the fact thatabrupt
cessation of ruxolitinib may lead to severe withdrawal symptoms
that include possible hemodynamic compromise and septic shock-
like syndrome [12]. One discussion of JAKi use in COVID-19 notes
only slightly increased infection rates in JAKi-treated patientsand
minimal pulmonary toxicities [13]. However, it is noted that cessa-
tion of JAKi therapy may be beneficial in COVID-19 infection to
avoid suppression of the antiviral response [13]. In addition, JAKis
are being studied for their potential use in COVID-19 for symptom
reduction in multiple organs through angiotensin II type 1 recep-
tor inhibition. They also may modulate inflammatory cytokines
during ARDS and lead to improvement in more severe COVID-19
cases [14].
In the setting of the COVID-19 public health crisis, non-essential
treatments have been delayed to prevent viral spread. In addition,
we must be extremely cautious in the highly susceptible population
undergoing HSCT. The European Society for Blood and Marrow
Transplantation has recommended that confirmed COVID-19 cas-
es should have HSCT deferred for 3 months in low-risk disease and
until asymptomatic with 3 negative PCR tests at least a week apart
in high-risk disease [15].
Several topics discussed in this case require further investigation.
Notably, inflammatory markers were not measured throughout
our patient’s disease course. There is evidence that C-reactivepro-
tein, procalcitonin, interleukin 6, and erythrocyte sedimentation
rate levels may correlate with disease severity [16]. Obtaining these
tests may determine severity of disease and alter the patient’s treat-
ment course. In addition, ruxolitinib reduces symptoms of MF
which may overlap with COVID-19, and it is unclear whether or
not this therapy should be continued after infection. Ongoing re-
search, including the RUXCOVID trial (NCT04362137) will ad-
dress its potential benefit in COVID-19illness.
6. Conclusion
Primary MF and immunosuppressive therapies may mask
COVID-19 symptoms and prevent or delay seroconversion. Pa-
tients with MF, especially when undergoing HSCT, should be
screened for COVID-19 and monitored carefully to improve safe-
ty. Clinicians cannot rely on symptoms as indicators of COVID-19
infection, particularly in patients withMF.
