Simple Summary: Breast cancer (BCa) is a pathology that affects the world population. Patients present risk factors for osteopenia and osteoporosis, such as chronic stress, estrogen deprivation due to hormonal treatment, a menopausal status, and decreased physical activity. An available alternative is the use of nonselective beta blockers (nsBBs) that have antitumoral properties, and in other diseases, antiresorptive and osteoforming effects. We demonstrated that BCa patients taking nsBBs had a greater bone mineral density and a lower incidence of osteoporosis and osteopenia than untreated patients. Although our study has several limitations, such as its retrospective design and single-center population, it revealed promising effects of nsBBs on the prevention and treatment of osteoporosis and osteopenia in patients with BCa. Breast cancer (BCa) is related to chronic stress and can reduce the bone mineral density (BMD) through neurochemicals related to beta-adrenergic receptor (ADRB) 1 and 2. Selective beta blockers (sBBs) and nonselective beta blockers (nsBBs) are used to treat systemic arterial hypertension (SAH) and may have osteoprotective effects, as they inhibit ADRBs. To evaluate the effects of sBBs and nsBBs on the BMD of Mexican patients with BCa. A retrospective study was conducted. We included 191 Mexican women with BCa without SAH and with SAH treated with nsBBs, sBBs, and diuretics. BMD was evaluated using a bone density scan (DEX scan). A greater average BMD (p < 0.05) was observed in patients with prior treatment with both nsBBs and sBBs (0.54 ± 0.94 and −0.44 ± 1.22, respectively) compared to patients treated with diuretics or without SAH (−1.73 ± 0.83 and −1.22 ± 0.98, respectively). Regarding the diagnosis of osteoporosis/osteopenia, no cases were observed in patients treated with nsBBs, whereas 5.6% of the patients treated with sBBs presented osteopenia. A total of 23.1% and 10.6% patients managed with diuretics or without treatment presented with osteoporosis and 61.5% and 48% patients managed with loop diuretics and without treatment presented with osteopenia, respectively (p < 0.05). Treatment with nsBBs is a promising option for the prevention and management of osteoporosis/osteopenia in Mexican patients with BCa; however, further prospective studies are needed.

Purpose: To evaluate the mechanical complications of weekly care and maintenance versus once every 10 days of the peripherally inserted central catheter (PICC) line insertion site versus once every 10 days in newborns., Design and Methods: Prospective propensity score matched cohort study. Care and maintenance of the PICC line insertion site were performed on days 7 and 10 during January 2018 to December 2019. To compare mechanical complications, propensity score matching was performed. Propensity scores were used to determine the relative risks and hazard ratios by using logistic regressions with log-link function and Cox regressions, respectively., Results: We included 175 newborns hospitalized in the neonatal intensive care unit (NICU) who underwent insertion of a PICC line. Ninety-six received weekly care and maintenance, and 79 received care and maintenance every 10 days. Weekly care and maintenance were associated with more breakage (RR 1.98, 95% CI 1.68-2.34); occlusions (RR 0.81, 95% CI 0.46-1.42) and accidental withdrawals (RR 1.31, 95% CI 0.93-1.84) were not different between care and maintenance every 7 and 10 days. A survival analysis was performed, showing that weekly care and maintenance are a risk factor for removal for mechanical complications (HR 7.61, 95% CI 3.05-19.01)., Conclusion: We concluded that care and maintenance of the PICC in newborns every 10 days have fewer complications than when performing care and maintenance every 7 days., Practice Implications: Newborns requiring intravenous therapy will benefit from care and maintenance every 10 days, and this practice could potentially spread to other NICUs., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2022 Elsevier Inc.

Metacercariae of Paragonimus mexicanus were collected in crabs Tehuana guerreroensis (Rathbun, 1933) in the municipality of Putla, Oaxaca, Mexico. Metacercariae were found in 20.8% of the crabs collected, with an average of 1.9 metacercarie per crab. Stained metacercariae showed the specific characteristics of P. mexicanus by morphology and sequencing a fragment of the 28S ribosomal gene obtained by PCR. These findings reveal that T. guerreroensis is an intermediate host for P. mexicanus; this new report is relevant considering the potential risk of transmission in the states of Oaxaca and Guerrero, Mexico., (Copyright © 2014 Elsevier B.V.
