Published: May 2021

Background: Recent imaging studies demonstrate that the anterolateral ligament (ALL) is frequently injured at the time of anterior cruciate ligament (ACL) rupture. The intrinsic healing potential of these injuries after ACL reconstruction (ACLR) has not been defined. Purpose/Hypothesis: The primary objective was to evaluate the rate and duration of the healing process of injured ALLs after ACLR using serial 3-dimensional magnetic resonance imaging (3D-MRI). The secondary objective was to investigate whether any patient, injury, or surgical factors influenced the healing rate. The hypothesis was that serial imaging would demonstrate that the ALL has limited healing potential. Study Design: Case series; Level of evidence, 4. Methods: Patients enrolled in the study underwent 3D-MRI (slice thickness 0.5 mm) preoperatively and at 1, 6, 12, and 24 months after ACLR. Three observers determined the grade of ALL injury according to the Muramatsu classification. Inter- and intraobserver reliabilities were calculated. The rates of injury and time points for healing were determined. Full healing was defined as a change from a preoperative Muramatsu grade of B or C (indicating partial or complete injury) to grade A (normal). Multivariate analysis was used to investigate the association of aforementioned factors with the risk of incomplete healing. Results: A total of 44 patients were enrolled in the study. Of them, 71.2% had an ALL injury on preoperative imaging. Overall, full healing of ALL injuries occurred at a rate of 3.2%, 15.2%, and 30.3% at 1, 6, and 12 months, respectively. There were no changes in the Muramatsu grade in any patient beyond 12 months postoperatively. None of the complete lesions demonstrated full healing, but the proportion of patients with a grade C injury decreased from 13.6% preoperatively to 4.5% at 12 months due to an improvement to grade B in 4 of 6 patients (66%). Inter- and intraobserver reliabilities of the classification system were almost perfect at 0.81-0.94 and 0.95-1.00, respectively. None of the potential risk factors investigated were predictive of an increased risk of nonhealing. Conclusion: ALL injuries occurred in the majority of ACL-injured knees. They had limited intrinsic healing potential, with only 30.3% healing by 12 months after ACLR. The process of healing took >6 months in half of the patients in whom it occurred. No new cases of full healing occurred beyond 12 months postoperatively. No significant risk factors for failure of full healing to occur were identified, but it is likely that this aspect of the study was underpowered.

Published: May 2021

Background: Food insecurity (FI) is common globally and can have lifelong consequences. However, few studies have longitudinally examined how FI varies across gestation and the postpartum period (“the first 1000 days”); none have explored this in sub-Saharan Africa or in the context of HIV. Objective: To assess the prevalence and covariates of FI in the first 1000 days among Kenyan women. Methods: All pregnant women attending 7 clinics in western Kenya (n = 1247) were screened for HIV and FI (Individual Food Insecurity Access Scale) between September 2014 and June 2015. A subset of women (n = 371) was recruited into an observational cohort study and surveyed 11 times through 2 years postpartum (NCT02974972, NCT02979418). Data on FI, sociodemographics, and health were repeatedly collected. Severe FI was modeled using multilevel, mixed-effects logistic regressions (n = 346). Results: Of the 1247 pregnant women screened, 76.5% were severely food insecure in the prior month. Further, the prevalence of severe FI was higher among women living with HIV than those without (82.6% vs 74.6%, P < .05). In the cohort, the odds of being severely food insecure decreased monotonically after delivery. Each point higher on the Center for Epidemiologic Studies-Depression scale was associated with 1.08 times greater odds of being severely food insecure (95% CI: 1.05-1.10); each point higher on the Duke/UNC Functional Social Support Scale was associated with 0.97 lower odds of severe FI (95% CI: 0.94-0.99). Conclusions: Severe FI is prevalent during the first 1000 days in western Kenya. Services to mitigate the far-reaching consequences of this modifiable risk should be considered.

Published: May 2021

Purpose: To evaluate the efficacy of endovascular treatment for vascular renal injuries (VRIs) like bleeding, pseudoaneurysm and artero-venous fistula (AVF) and to compare patients with blunt trauma (T-VRIs) with those with iatrogenic damage (I-VRIs). Methods: We retrospectively assessed 49 renal artery embolizations performed to treat T-VRIs (26.5%) and I-VRIs (73.5%). Different embolic materials were used based on the type of lesion. Technical success was defined as the complete occlusion of target arteries with no further visualization of VRIs. Clinical success was defined if no recurrence was present and if renal function (difference between creatinine after and before treatment <0.5 mg/dl) was preserved after 1 month. Results: Angiography showed bleeding in 27 patients, pseudoaneurysm in 29 and an AVF in 6. Embolic agents used were coils in 39 procedures, coils with sponge in four and others in six. Technical success was 100% while clinical success was 85.7% due to seven patients with recurrence. The group I-VRIs showed a higher rate of clinical success than the group T-VRIs (94.4% vs 61.5%; p < 0.05). Moreover, the group I-VRIs had a higher incidence of pseudoaneurysms and AVFs compared with the group T-VRIs (69.4% vs 30.8% and 16.7% vs 0%; p < 0.05). Conclusion: Endovascular treatment for VRIs showed satisfactory results and no patient had a worsening of renal function. I-VRIs had better clinical success and more frequently appeared as pseudoaneurysms compared to T-VRIs: probably iatrogenic injury is localized and pseudoaneurysm is easily identifiable and treatable with endovascular treatment.

Published: May 2021

Background: We experienced a high incidence of pulmonary barotrauma among patients with coronavirus disease-2019 (COVID-19) associated acute respiratory distress syndrome (ARDS) at our institution. In current study, we sought to evaluate the incidence, clinical outcomes, and characteristics of barotrauma among COVID-19 patients receiving invasive and non-invasive positive pressure ventilation. Methodology: This retrospective cohort study included adult patients diagnosed with COVID-19 pneumonia and requiring oxygen support or positive airway pressure for ARDS who presented to our tertiary-care center from March through November, 2020. Results: A total of 353 patients met our inclusion criteria, of which 232 patients who required heated high-flow nasal cannula, continuous or bilevel positive airway pressure were assigned to non-invasive group. The remaining 121 patients required invasive mechanical ventilation and were assigned to invasive group. Of the total 353 patients, 32 patients (65.6% males) with a mean age of 63 ± 11 years developed barotrauma in the form of subcutaneous emphysema, pneumothorax, or pneumomediastinum. The incidence of barotrauma was 4.74% (11/232) and 17.35% (21/121) in the non-invasive group and invasive group, respectively. The median length of hospital stay was 22 (15.7 −33.0) days with an overall mortality of 62.5% (n = 20). Conclusions: Patients with COVID-19 ARDS have a high incidence of barotrauma. Pulmonary barotrauma should be considered in patients with COVID-19 pneumonia who exhibit worsening of their respiratory disease as it is likely associated with a high mortality risk. Utilizing lung-protective ventilation strategies may reduce the risk of barotrauma.

Background Systemic lupus erythematosus (SLE) increases the incidence of adverse pregnancy outcomes (APOs). Nevertheless, most of the data on SLE pregnancies were derived from database studies in which details of the pregnancies were unavailable, and no consensus exists on the risk of APO in patients with prior severe organ manifestations. Methods SLE patients followed by rheumatologists and gynecologists throughout pregnancy at our institute were retrospectively identified, and their data between April 2003 and December 2020 were reviewed from electronic records. We assigned patients based on the presence of prior severe organ manifestation (renal/neurological manifestation, prior treatment with methylprednisolone pulse therapy/prednisolone 1 mg/kg/day/biological or cytotoxic therapy) and compared the incidence of overall and serious APO (maternal death, pregnancy loss, preterm birth <32 weeks, birthweight <1500 g, Apgar score <7 at 5 min and birth defect). Results This study included 34 pregnancies in 32 patients; 23 pregnancies in 22 patients were classified as SLE with prior severe organ manifestation. There was no statistical difference in the incidence of overall APO between the two groups (52.2% vs 45.5%, P = 1). Among patients with prior severe organ manifestation, 17.4% had serious APO. A detailed electronic health record search revealed specific causes of APO in all pregnancies with serious APO, except the presence of prior severe organ manifestation. Conclusion The incidence of overall APO in SLE patients was not affected by prior severe organ manifestation. Although the incidence of serious APOs increased in patients with previous severe organ manifestation, there were other risk factors for poor pregnancy outcomes besides prior lupus severity. Therefore, proper management by rheumatologists and gynecologists may enable patients with prior severe organ manifestation to safely deliver healthy babies.

Published: May 2021

Background Tissue resident memory T cells (TRMs) persist long-term in peripheral tissues without recirculation, triggering an immediate protective inflammatory state upon the re-recognition of the antigen. Despite evidence incriminating the dysregulation of TRMs in autoimmune diseases, few studies have examined their expression in cutaneous lupus erythematosus (CLE). Objectives We aimed to examine whether there are differences among TRM populations in CLE depending on different clinical conditions, such as the CLE subtype or association with systemic lupus erythematosus, and to determine the effect of type I interferon (IFN) on the development of TRMs in CLE. Methods CLE disease activity was evaluated using the Cutaneous Lupus Erythematosus Disease Area and Severity Index. The expression of the TRM markers CD69 and CD103 in CLE lesions was evaluated by immunofluorescence. Flow cytometry was performed on peripheral blood mononuclear cells after IFNα treatment. Results The number of TRMs expressing either CD69 or CD103 was significantly higher in CLE lesions than in control skin; however, it was not significantly different between discoid lupus erythematosus and subacute CLE, or dependent on the presence of concomitant systemic lupus. Lesional severity was not correlated with an increase in TRMs in CLE. IFNα treatment induced a conspicuous increase in CD69 expression in skin-homing T cells, more profoundly in CD4+ T cells than in CD8+ T cells. Conclusions Skin TRMs, either CD69 or CD103-positive cells, showed increased levels in the lesional skin of CLE, and IFNα increased the expression of CD69 in T cells.
What Types of Exercise Are More Effective in Reducing Obesity and Blood Pressure for Middle-Aged Women? A Systematic Review With Meta-Analysis
Authors: Park Seong-Hi , Kim Chul-Gyu 
Published: May 2021

Background: A systematic review was performed to identify the types of physical activities effective as interventions in preventing metabolic syndrome in middle-aged women. Methods: Electronic databases (MEDLINE, EMBASE, the Cochrane Library, and CINAHL) served as the data sources. Cochrane’s Risk of Bias 2 was applied to assess the risk of bias of the randomized controlled trials. Meta-analyses were performed on selected studies using Review Manager 5.3. Thirty-one trials enrolling 2,202 participants were included. Results: Compared to controls, the effects of physical activity were indicated by pooled mean differences, which were −0.57 kg for body weight, −0.43 kg/m2 for body mass index, −1.63 cm for waist circumference, −4.89 mmHg for systolic blood pressure (BP), and −2.71 mmHg for diastolic BP. The effects were greater on the measurements of waist circumference and BP than on body weight and BMI. The types of physical activities were further analyzed according to sub-groups. Only aerobic exercise did not affect body weight and resistance exercise did not significantly change any results. Contrarily, combined exercises significantly reduced measurements of waist circumference and BP. Conclusion: This review can provide valuable information for research and implementation of measures to prevent metabolic syndrome in middle-aged women.
Collision tumor of sebaceous carcinoma and squamous cell carcinoma of the eyelid: Case report
Authors: Wang Jin-Jhe , Lee Kam-Fai , Chen Chau-Yin 
Published: May 2021

Background: Collision tumors are rare clinical entities that two heterogeneous neoplasms are concurrently adjacent to each other at the same location. The association of a squamous cell carcinoma and a malignant adnexal tumor is even infrequent. Case presentation: The case of a 79-year-old woman having a slow-growing and painless tumor on the left lower eyelid was presented. The lesion, about 15 mm in diameter, was nodular, irregular, and yellow-discolored. Histopathologic and immunohistochemical findings disclosed concurrence of sebaceous carcinoma as well as squamous cell carcinoma in one specimen. Wide excision of the tumor with frozen section control and eyelid reconstruction were performed. Oncologic survey revealed no other lesion. At 6-month follow-up, no evidence of recurrence or metastasis was presented. Conclusion: Collision tumor composed of sebaceous carcinoma and squamous cell carcinoma in eyelid may be the first case described in the literature. For increasing accuracy of diagnosis and management, a thorough clinical examination and detailed histopathologic analysis, along with multidisciplinary discussion, are prerequisites.

Published: May 2021

Purpose: Previous reports described unfavorable visual outcomes after surgery for uveitic macular pucker. Our goal was to demonstrate that patients with history of uveitis may benefit from vitrectomy for epiretinal membrane if executed under appropriate circumstances. Methods: We performed pars plana vitrectomy with ERM and ILM peeling in patients with post-uveitic macular pucker who did not show signs of ocular inflammation for at least 3 months after the suspension of immunosuppressive therapy. Visual acuity, central macular thickness at OCT, ocular inflammation, and complications were recorded. Results: Twenty-six eyes were operated. Mean duration of follow-up was 67 months. Visual acuity significantly improved from 20/80 to 20/40 after surgery. Vision increased in 20 (77%), remained stable in 4 (15%), and decreased in 2 (8%) eyes. Best-corrected visual acuity ameliorated by at least 2 ETDRS lines in 14 eyes (54%). Contingency analysis did not show any statistical difference among the different types of uveitis ( p = 0.46). Mean central foveal thickness improved postoperatively (428 ± 104 vs 328 ± 130 microns; p = 0.017). Conclusion: Patients with uveitic epiretinal membrane benefit from vitrectomy with membranectomy if operated when intraocular inflammation had subsided.

Purpose: The aim of this study was to assess whether the intraoperative use of the cold eye irrigation balanced salt solution (BSS) could have a protective effect in preventing the anterior chamber flare and conjunctival hyperemia and, thus, in reducing patients discomfort after phacoemulsification. Materials and methods: About 214 patients were enrolled and randomly divided into: patients whose eye were irrigated with BSS at ~ 20°C (Group 1) and patients whose eye were irrigated with BSS at 2.7°C (Group 2). Anterior chamber flare, visual analogue score and conjunctival hyperemia were evaluated at 1, 3, 5, and 30 days after surgery. Results: In patients of Group 2 the anterior chamber flare, the visual analogue score and the conjunctival hyperemia, used as parameters to evaluated clinical inflammation, at 1 day after surgery were significantly lower than those in Group 1 who received BSS solution at operating room temperature ( p < 0.001), while at day 3, 5, and 30 there were not any significant differences. Conclusion: Our study provided evidence supporting the efficacy of the treatment with cold irrigation solution on reduction of anterior chamber flare, pain and conjunctival hyperemia already at 1 day after phacoemulsification, suggesting that cooling procedure was fully effective at controlling early post-operative inflammation.
‘It’s always difficult when it’s family. . . whereas when you’re talking to a therapist. . .’: Parents’ views of cognitive-behaviour therapy for depressed adolescents
Authors: Schlimm Katharina , Loades Maria , Hards Emily , Reynolds Shirley , Parkinson Monika , Midgley Nick 
Published: May 2021

Background: Parents are key to helping their adolescent child access psychological therapy for mental health problems such as depression. However, little is known about how parents experience their child’s psychological therapy. We aimed to explore parents’ experiences of their adolescent child’s cognitive behaviour therapy for depression. Method: We applied Thematic Analysis (TA) to qualitative data from in-depth interviews with parents ( N = 16) whose adolescent child was randomly allocated to CBT in a large multisite RCT for adolescent depression (the IMPACT trial). Interviews were conducted at the end of treatment. Results: We generated two main themes: parents’ perceptions of the adolescent’s journey through therapy, and parents’ perceptions of the therapeutic setting and process. Each included four sub-themes. Parents talked about key factors that impacted on their child’s progress through treatment, including the adolescent’s readiness for therapy and the adolescent-therapist relationship. Conclusion: Parents’ insights confirm the foundations of what is considered good clinical practice of CBT for adolescent depression, including tailoring therapy to the adolescent, and establishing a strong adolescent-therapist relationship. Parents recognised that, for CBT to be helpful, their child had to be willing to engage in therapy and able to develop a trusting relationship with their therapist.

Published: May 2021

Prostate cancer is the second leading cause of cancer death in men. Its current treatment includes various physical and chemical approaches for the localized and advanced prostate cancer [e.g. metastatic castrate resistant prostate cancer (mCRPC)]. Although many new drugs are now available for prostate cancer, none is suitable for local treatment that can reduce adverse effects often associated with the current physical treatment. Of the drugs approved by FDA for mCRPC, the best mean improvement in overall survival is only about 4.8 months. Therefore, there is a need for improved treatment approaches for prostate cancer, especially drug-resistant cancer. Ultrasound therapy represents a useful new physical approach for the drug-resistant cancer treatment by facilitating the entry of the related chemotherapy drug into the target cancer cells. There are two versions of ultrasound: High Intensity Focused Ultrasound (HIFU) and Low Intensity Pulsed Ultrasound (LIPUS). HIFU has been a promising treatment option for prostate cancer due to its noninvasiveness and various biological effects on cancer tissue. It has been approved for the treatment of cancer and in recent years there have been numerous findings suggesting HIFU can reduce cancer cell viability and possibly reverse the spread of cancerous tumors. LIPUS is currently being studied as an alternative treatment option for prostate cancer. Preliminary studies have found LIPUS to reduce cancer cell viability without the side effects seen in HIFU. Reversible cell membrane damage caused by LIPUS could allow increased uptake of anticancer drugs, enhancing cytotoxicity and death of cancer cells. In this way, a low dose of anticancer drug is more effective toward cancer cells while there is less damage to normal cells. The combination of LIPUS with certain chemotherapeutic agents can be an exciting physical-chemical combination therapy for prostate cancer. This review will focus on this topic as well as the clinical use of HIFU to provide an understanding of their current use and future potential role for prostate cancer therapy.
