Follicle-stimulating hormonal promotes development of human being prostate cancer cell line-derived growth xenografts.
However, the difference between the two groups was not significant for this variable (p = 0.438).

An association was observed between the polymorphisms and the warfarin doses taken by the patients. However, there was no association with adverse events or the time spent within the therapeutic range in this sample.

The aim of carotid interventions is to prevent cerebrovascular events. Endovascular treatment (carotid-artery-stenting/CAS) has become established as an alternative to open surgery in some cases. Historically, female sex has been considered as a perioperative risk factor, however, there are few studies regarding this hypothesis when it comes to CAS.

To analyze the CAS results in our center adjusted by sex.

A retrospective cohort study was designed, including patients with carotid atheromatosis operated at a single center from January 2016 to June 2019. Our objective was to compare cardiovascular risk, including myocardial infarction, stroke, and mortality, by sex. Follow-up rates of stent patency, restenosis, stroke, myocardial infarction, and death were reported.

71 interventions were performed in 50 men (70.42%) and 21 women (29.57%). Mean age was 70.50 ± 10.72 years for men and 73.62 ± 11.78 years for women. Cardiovascular risk factors did not differ significantly between sexes. Mean follow-up was 11.28 ± 11.28 months. There were no significant differences in neurological events during follow-up. No adverse cardiological events were detected at any time. Regarding the mortality rate, during medium-term follow up there were 2 neurological related deaths with no significant differences between sexes (p=0.8432). Neither sex had higher rated of restenosis during long term follow-up (5.63%
1.41%, p = 0.9693) or reoperation (1.41%
1.41%, p = 0.4971). All procedures remained patent (<50% restenosis).

Despite the limitations of our study, CAS is a therapeutic option that is as effective and safe in women as in men. No sex differences were observed.

There is a spectrum of possibilities for analyzing muscle O
resaturation parameters for measurement of reactive hyperemia in microvasculature. However, there is no consensus with respect to the responsiveness of these O
resaturation parameters for assessing reactive hyperemia.

This study investigates the responsiveness of the most utilized muscle O
resaturation parameters to assess reactive hyperemia in the microvasculature of a clinical group known to exhibit impairments of tissue O
saturation (StO
).

Twenty-three healthy young adults, twenty-nine healthy older adults, and thirty-five older adults at risk of cardiovascular disease (CVD) were recruited. Near-infrared spectroscopy (NIRS) was used to assess StO
after a 5-min arterial occlusion challenge and the following parameters were analyzed StO
, StO
, and StO
(upslope of StO
over 10s and 30s and until StO
reaches the baseline value); time to StO
and time to StO
(time taken for StO
to reach baseline and peak values, respectively); ∆StO
(the difference between minimum and maximum StO
values); total area under the curve (StO
); and AUC above the baseline value (StO
).

Only StO
was significantly slower in older adults at risk for CVD compared to healthy young individuals (p < 0.001) and to healthy older adults (p < 0.001). Conversely, time to StO
was significantly longer in healthy young individuals than in older adult at CVD risk.

Our findings suggest that StO
may be a measure of reactive hyperemia, which provides clinical insight into microvascular function assessment.

Venous ulcers (VU) are the most advanced stage of chronic venous disease (CVD) of the lower limbs. They are frequently associated with episodes of hemorrhage that can provoke chronic anemia (CA), delaying healing. There are no studies in the literature analyzing the prevalence of CA among patients with VU of the lower limbs and few studies have analyzed use of pentoxifylline to treat VU of the lower limbs.

To evaluate the prevalence of CA in patients with lower limb VU and responses to treatment with ferrous sulfate (SF) compared with a combination of SF plus pentoxifylline as adjuvant treatment for VU of the lower limbs.

A total of 67 patients with lower limb VU were recruited from a Lymphedema and Angiodysplasia Clinic at the Hospital das Clínicas, Recife, PE, Brazil. Bcl-2 protein After initial clinical and laboratory assessments, patients diagnosed with CA were randomized into one of two groups a control group, given SF (900 mg/day oral route), or a study group, treated with SF (900 mg/day oral route) and pentoxifylline (1,200 mg/day). All were reassessed after 90 days.

Twenty-seven patients (40%) had CA. After treatment, increases were observed in hemoglobin and hematocrit levels, iron kinetics had improved, and both depth and area of VU had reduced in both groups, without statistically significant differences.

A high prevalence of anemia was detected in the study population. The combination of SF and pentoxifylline was not more effective than SF alone for adjuvant treatment of VU of the lower limbs.

Biotechnological advances have allowed to create rapidly vaccines, yet the success of an efficient immunization mainly depends on the safe and timely delivery of vaccines. In particular, packaging plays a crucial role in protecting, preserving, transporting, and distributing vaccines. Here, we review advanced packaging for distribution and storage of COVID-19 vaccines, with focus on innovative hybrid packaging materials, cyclic olefin polymers with nanolayer glass, and vials for vaccines. We present vaccine packaging, auto-disable syringes, stoppers, and closures. We discuss the chronology of the packaging system, and the labeling of the vaccine packages, with emphasis on bar codes, quick response codes, vaccine vial monitors, anti-counterfeiting and traceability measures.
