Is There a Baby in the Lung? A Case of Placental Transmogrification of the Lung.

Pulmonary nodules are commonly encountered in pulmonary practice. Etiologies could include infectious, inflammatory, and malignant. Placental transmogrification of the lung is an extremely rare etiology of pulmonary nodules. Such condition often presents as unilateral lesions in asymptomatic men. In general, such nodules are generally stable and grow extremely slowly. We highlight an unusual case of placental transmogrification of the lung (PLC) identified in a young female. The patient's bilateral nodules were larger than what has been previously cited in the literature and exhibited growth over an 8-year follow-up period.

Impact of Remote Patient Monitoring Platform on Patients With Moderate to Severe Persistent Asthma: Observational Study.

BACKGROUND: Asthma is one of the most common respiratory diseases, with an ever-growing health care burden. Remote patient monitoring (RPM) has gained increasing importance in the respiratory care area with the outbreak of the COVID-19 pandemic. In this pilot study, we introduced a novel platform that remotely monitors patients with chronic respiratory illnesses using Centers for Disease Control and Prevention guidelines to reduce hospitalizations and emergency department visits. OBJECTIVE: This study aimed to understand patient and physician engagement with a new virtual care solution (KevaTalk app and Keva365 platform) and the value, for both patients and providers, of using an RPM tool. We assessed real-world use of the platform from both physician and patient perspectives and the impact of devices on engagement and monitoring. METHODS: Participants with a history of moderate to severe persistent asthma, seen by a pulmonologist at a hospital, were included in this study. The inclusion criteria involved being aged ≥18 years and having access to an Android or iOS mobile device with internet. We provided patient questionnaires to assess the app's usefulness and evaluate its features. We monitored remote spirometry and oximetry data, app check-ins, alerts, and escalations during this study's time window. Data were reviewed daily and predetermined criteria were set to escalate for physician review based on the patient's symptoms and objective data. RESULTS: Overall, 25 patients were included in this pilot. The mean age was 57 (SD 10.7) years and a majority (n=23, 92%) were female. A baseline questionnaire, which was used to rate the app, indicated that the ease of check-in and ease of modification to the patient's asthma plan were the 2 highest rated features. In total, 2066 check-ins (1550 green, 506 yellow, and 10 red check-ins) and 1155 spirometry sessions were recorded during this 3-month period. Further, 64% (14/22) and 91% (20/22) of patients were found to have peak flows in their red and yellow zones at least once, respectively. During the course of this study, 484 alerts were recorded and evaluated by the team, of which 37.2% (n=180) required an escalation to the physician; this included a transfer to a medical facility, change in respiratory medication, or further education. CONCLUSIONS: In this pilot study, we demonstrated the feasibility of implementing a novel RPM platform in patients with asthma. Our platform showed high patient engagement and satisfaction and provided physicians with real-time subjective data to evaluate patients remotely that aids in clinical decision-making. The escalations prevented patients from having an exacerbation or flare up, which led to the prevention of an emergency department visit. Continuous monitoring of chronic disease has benefits over episodic monitoring. It allows for improved quality of life, better outcomes, and huge health care savings.

Association of Recipient APOL1 Kidney Risk Alleles With Kidney Transplant Outcomes.

BACKGROUND: Kidney transplant survival in African American recipients is lower compared with non-African American transplant recipients. APOL1 risk alleles (RA) have been postulated as likely contributors. We examined the graft outcomes in kidney transplant recipients (KTRs) stratified by APOL1 RA status in a multicenter observational prospective study. METHODS: The Renal Transplant Outcome Study recruited a cohort of incident KTRs at 3 transplant centers in the Philadelphia area from 1999-2004. KTRs were genotyped for APOL1 RA. Allograft and patient survival rates were compared by the presence and number of APOL1 RA. RESULTS: Among 221 participants, approximately 43% carried 2 APOL1 RA. Recipients carrying 2 APOL1 RA demonstrated lower graft survival compared with recipients with only 1 or none of APOL1 RA at 1 y posttransplant, independently of other donor and recipient characteristics (adjusted hazard ratio 3.2 [95% confidence interval, 1.0-10.4], P = 0.05). There was no significant difference in overall survival or graft survival after 3 y posttransplantation. There was no difference in death by APOL1 -risk status ( P = 0.11). CONCLUSIONS: Recipients with 2 APOL1 high-risk alleles exhibited lower graft survival 1 y posttransplantation compared with recipients with only 1 or 0 APOL1 RA. Further research is required to study the combined role of the recipient and donor APOL1 genotypes in kidney transplantation.

Routine cavity shaves following breast conserving surgery; friend or foe?

BACKGROUND: Radial margin status is considered one of the most important prognostic predictor for patients undergoing breast-conserving surgery (BCT), not only related to regional recurrence but also to 5y survival, especially in patients with invasive disease. AIM: While our primary aim was to evaluate whether doing routine radial cavity shaves following at the time of primary conservative breast surgery will decrease the need for a second operation or not, our secondary aim was to assess time added to the operation to resect and mark the radial shaves, as well as patients' satisfaction with the results. MATERIAL AND METHODS: We have conducted a case series prospective analysis, including158 patients who underwent breast-conserving surgery looking into the histological status of resection margins and radial shaves, added time taken to take and mark the shaves as well as patients' satisfaction. RESULTS: 158 female breast cancer patients have been included in our analysis, the mean age was 56 years; total number of lesions was 160. While 89.3% of lesions were palpable, 10.6% were not requiring wire-guided localisation. Mean tumour size was 24 mm SD 7, final histology revealed that 86.8% lesion was invasive ductal carcinoma, 5.6% invasive lobular carcinoma, 1.2% medullary carcinoma. 12.4% had invasive disease as well as DCIS, and 1.8% had DCIS only with no invasive disease. Mean preoperative breast volume was 723 ml, Mean wide local excision specimen weight was 73 g, and mean shave weight was 1.6 g. Total number of radial margins was 640, 81.8% was clear, 14.6% was close, and 3.4% was involved. Total number of shaves was 640 out of which 98.7% was clear 0.7% was close and 0.4% was involved. Out of the 160 lesions, 3.7% required a second procedure to clear margins, out of which 2.5% had re-excision for close or involved single shaves each while 1.2% had mastectomy due to close or involved two shaves each. Average time utilised in resection of radial shaves and marking was 7 min 0.6% of patients developed a haematoma, 1.8% had a Seroma, and 1.2% had wound infection. Mean hospital stay was 1day SD 1. CONCLUSION: Routine radial cavity shaves not only ensure microscopic clearance, reduce the need for re-excision with no significant added operating time but also has no impact on patients' satisfaction.

Vitamin D Analogues and Coronary Calcification in CKD Stages 3 and 4: A Randomized Controlled Trial of Calcitriol Versus Paricalcitol.

RATIONALE & OBJECTIVE: Mineral and bone disorder in chronic kidney disease (CKD) is associated with progression of coronary artery calcification (CAC). Mineral and bone disorder often is treated with calcitriol and other vitamin D receptor activators, including paricalcitol, agents that may have differential effects on calcium, phosphate, and parathyroid hormone levels. Accordingly, we investigated whether these agents have differential effects on CAC progression in patients with CKD. STUDY DESIGN: Randomized, double-concealed, 48-week clinical trial. SETTING & PARTICIPANTS: CKD stage 3 or 4 with secondary hyperparathyroidism with CAC score > 0 and no prior treatment with activated vitamin D. INTERVENTION: Calcitriol versus paricalcitol. OUTCOMES: The primary outcome was log-transformed CAC change. Secondary outcomes included percent change in CAC volume, valvular calcifications, and bone mineral metabolism markers. RESULTS: Among 44 individuals randomly assigned, mean age was 65 years and mean estimated glomerular filtration rate was 27 mL/min/1.73 m2. Median CAC score was 140 (IQR, 55-277) Agatston units at baseline. There was no significant difference in CAC progression between treatment arms (P = 0.06). After adjustment for baseline CAC score (log), treatment group remains nonsignificant (P = 0.08). Further adjustment for creatinine level and/or CKD stage did not change the association. In secondary analyses adjusting for dose level of activated vitamin D, treatment group was significant (P = 0.01), and when dose level was also included in the model, the coefficient for individuals in the paricalcitol group was significantly associated with CAC progression (P = 0.02). An interaction term between dosing level and CKD stage was significant at the highest dosing level (P = 0.04). LIMITATIONS: Pilot single-center study. CONCLUSIONS: In patients with CKD with secondary hyperparathyroidism naive to activated vitamin D therapy, there was no difference in CAC or valvular progression in participants receiving calcitriol compared with paricalcitol during a 48-week period.

Effects of Smoking on Solid Organ Transplantation Outcomes.

Tobacco smoking is the leading preventable cause of death worldwide. Both donor and recipient smoking have been shown to increase graft loss and mortality in solid organ transplant recipients in many studies. Only in lung transplants is smoking a universal contraindication to transplantation. Transplant centers implement different policies regarding smoking recipients and allografts from smoking donors. Due to scarcity of available allografts, the risks of smoking have to be weighed against the risks of a longer transplant waitlist period. Although transplant centers implement different strategies to encourage smoking cessation pre- and post-transplant, not many studies have been published that validate the efficacy of smoking cessation interventions in this vulnerable population. This article summarizes the results of studies investigating prevalence, impact on outcomes, and cessationinterventions for smoking in the transplant population. We report herein a review of the elevated risks of infection, malignancy, graft loss, cardiovascular events, and mortality in solid organ transplant populations.

Diabetes and the solid organ transplant recipient.

Solid organ transplant candidates undergo very strict screening for cardiovascular risk. Such screening has permitted significant decreases in cardiovascular morbidity and mortality over the ensuing decades of follow up. Long term follow-up has enabled us to identify an increasing incidence of pulmonary and urinary tract infections with or without sepsis as competing factors of morbidity and mortality. Indeed, all-cause mortality may now be dominated by infection-related endpoints. No population of transplant recipients is more naturally susceptible to infection as a diabetic subset, now submitted to immunosuppression. The current review details infection risk for kidney, liver, heart, and lung allograft recipients. A specific feature of this report emphasizes the enhanced risk for bacterial and fungal infection found in diabetic allograft recipients on immunosuppression therapy. The risk of repeated prescription of antibiotics in terms of evolutions of resistant strains of infectious pathogens is emphasized.

Traumatic complex splenic arteriovenous fistula causing prehepatic portal hypertension and variceal bleeding: the importance of the diagnosis for the endovascular treatment approach.

We report a case of a 68-year-old female patient presenting with portal hypertension and variceal bleeding in the absence of any liver disease. After performing a computed tomography angiogram, the cause of her condition was identified to be a splenic arteriovenous fistula (SAVF). After confirming the findings with angiography, we opted to treat the condition with coil embolization as an alternative to a more invasive surgical treatment. Coil embolization of the SAVF was performed successfully resulting in the improvement of the patient's variceal congestion. Our case highlights the importance of identifying SAVF as a potentially curable cause of variceal bleeding in the absence of liver disease. Seeking this diagnosis is of utmost importance since it completely changes the endovascular approach and management of these patients with variceal bleeding. We describe a minimally invasive endovascular technique for treatment of these critically ill patients.
