BACKGROUND: Cancer recurrence following surgical resection is a major cause of treatment failure. Finding effective methods to prevent postoperative recurrence and wound infection is an important component of successful surgery. With the development of new nanotechnology, more treatment options have been provided for postoperative adjuvant therapy. This study presents an innovative hydrogel system that stimulates tumoricidal immunity after surgical resection of non-small cell lung cancer (NSCLC) and prevents cancer relapse.
RESULTS: The hydrogel system is based on the excellent photothermal conversion performance of single-atom platinum (CN-Pt) along with the delivery and release of the chemotherapy drug, gemcitabine (GEM). The system is coated onto the wound surface after tumor removal with subsequent near-infrared (NIR) photothermal therapy, which efficiently induces necroptosis of residual cancer cells, amplifies the levels of damage-associated molecular patterns (DAMPs), and increases the number of M1 macrophages. The significantly higher levels of phagocytic macrophages enhance tumor immunogenicity and sensitize cancer cells to CD8 + T-cell immunity to control postoperative recurrence, which has been verified using an animal model of postoperative lung cancer recurrence. The CN-Pt-GEM-hydrogel with NIR can also inhibit postoperative wound infection.
CONCLUSIONS: These findings introduce an alternative strategy for supplementing antitumor immunity in patients undergoing resection of NSCLC tumors. The CN-Pt-GEM-hydrogel with the NIR system also exhibits good biosafety and may be adaptable for clinical application in relation to tumor resection surgery, wound tissue filling, infection prevention, and recurrence prevention.

UNASSIGNED: The major aim of our meta-analysis was to review the effectiveness of various treatment modalities for achieving successful remission and preventing recurrence for women with idiopathic granulomatous mastitis (IGM). This knowledge is instrumental in developing evidence-based guidelines for clinicians to improve management strategies and outcomes for patients with IGM.
UNASSIGNED: A systematic literature search was performed on MEDLINE (Ovid), Embase (Elsevier), PubMed, Cochrane Library, Web of Science, and Google Scholar; studies published to 19 January 2022 were included. A meta-analysis of 57 observational studies was performed. The results of two randomized controlled trials were also examined.
UNASSIGNED: There were 3,035 IGM patients across the observational and randomised studies. Overall recurrence and remission rates across all treatment strategies in 59 studies are 87.9% (2,667/3035) and 13.5% (359/2667), respectively. The studies reported 19 different treatment strategies, comprising observation, medical monotherapies, surgery, and combinations involving medical therapies, with and without surgery. Among monotherapy treatment, surgical management had the highest pooled remission rate (0.99 [95% confidence interval (CI) = 0.97-1.00]); among combination therapy, this was steroids and surgery (0.99 [0.94-1.00]). Antibiotic monotherapy had the lowest remission rate (0.72 [0.37-0.96]). The highest recurrence rates belonged to treatments that combined antibiotics and surgery (0.54 [0.02-1.00]), and antibiotics, steroids, and surgery (0.57 [0.00-1.00]). Most successful for preventing recurrence were observation (0.03 [0.00-0.10]), methotrexate (0.08 [0.00-0.24]), and steroids and surgery (0.05 [0.01-0.12]). There is a significant association between longer follow-up duration and recurrence rate reported, p = 0.002.
UNASSIGNED: Combination therapies, especially those incorporating antibiotics, steroids, and surgery, have demonstrated higher remission rates, challenging the use of antibiotic monotherapy. There is an increased emphasis on the need for personalised, multi-pronged approach for preventing IGM recurrence, with longer follow-up care. More prospective future work in IGM research, with standardised diagnostic criteria, treatment protocols, and reporting guidelines will be important for developing treatment protocols and guidelines clinicians can adhere to in the clinical management of IGM patients.Systematic review registration: PROSPERO (CRD42022301386).

Due to the sequelae and recurrence in patients with COVID-19 after recovery. This article, based on the theory of \"preventive treatment of diseases\" in traditional Chinese medicine, which believes that the three pathogenic factors of epidemic toxin, dampness, and lung deficiency are the fundamental causes of the recurrence of COVID-19. The treatment strategies are to remove pathogenic factors, strengthen qi, nourish yin, clear heat, moisten dryness, and at the same time, reinforce the lung, spleen and kidney, and soothe the liver. Through a variety of treatments such as oral administration, external treatment, and skin absorption, it provides a new idea and method for the management of the recurrence of COVID-19.

Seeking a potent therapeutic strategy for alleviating atopic dermatitis (AD) attack and preventing its recurrence is highly desired but remains challenging in clinical practice. Here, we propose an inflammation-responsive double-layer microneedle (IDMN) patch in situ delivering VD3 for recurrent AD therapy. IDMN comprises the backing layer part and the double-layer microneedle part, in which the inner layer is gelatin methacryloyl (GelMA) loaded with VD3 while the outer layer is composed of hyaluronic acid (HA). Introduction of the HA backing layer and outer layer around the GelMA tips can not only provide sufficient mechanical strength to penetrate into hardened AD skin with minimal invasiveness, but also exert a strong moisturizing effect after being rapidly dissolved. The inner layer of GelMA is degraded by the matrix metalloproteinase (MMP) in a dose dependent manner, which is secreted according to the disease progression of AD. The responsive degradation of GelMA tips result in corresponding release of VD3 to treat AD, triggering negative feedback against GelMA degradation. The IDMN administration on AD-bearing mice reveals efficient \"curing\" performances (including suppress erythema, scaling and lichenification, reduce epidermal thickness, inhibit mast cells infiltration, and down-regulate inflammatory factor secretion), which are basically realized through synergistic effect of the released VD3 and the dissolved HA molecules. Importantly, the residual tips of IDMN with VD3 are retained in the skin after the first AD relief, showing promising \"warning\" ability to inhibit the recurrence of AD. Hence, the developed IDMN patch is expected to be one of the excellent candidates for AD therapy and other relapsing diseases in clinical fields.

The present study aimed to clarify the humoral and cellular immune responses of patients with cancer who experienced no recurrence over a long term after receiving a cancer vaccine. The immune kinetics were investigated in response to a personalized peptide vaccination (PPV) among 44 Japanese patients without an active tumor at entry to the vaccination: Lung adenocarcinoma (n=11); colon (n=18); and breast cancer (n=15) (9, 10, 12, 8 and 5 patients with stage I, II, III and IV recurrences, respectively). The patients\' immunoglobulin G (IgG) and cytotoxic T lymphocyte (CTL) activities were measured using a multiplexed Luminex assay and an interferon-γ release assay, respectively. There were no severe adverse events related to the PPV other than a grade III injection site reaction. A potent boost in IgG or CTL at the end of the 1st vaccination cycle was observed in 77% of the patients (n=84). The IgG levels were sustained throughout the follow-up period, whereas the CTL levels declined and were transient. A total of 37 of the 44 patients (84%) had no recurrence, with a median follow-up of 67.6 months (interquartile range, 45.6-82.8 months). Overall, the PPV induced long-term humoral immunity with transient cellular immunity in the majority of patients with cancer without an active tumor at their entry to the PPV.

OBJECTIVE: The implementation of preventive clinical actions in Primary Care would allow to act on the high incidence of urolithiasis and the correctable risk factors. This pilot study compared a systematic follow-up (SFU) versus a regular follow-up (RFU) in terms of feasibility, safety and clinical outcomes.
METHODS: We conducted a multicentric and controlled pilot study in 30 patients comparing SFU versus RFU. Patients followed allocation concealment by an independent blocked computer-generated list. We defined \"success\" if feasibility objectives were matched including recruitment rate, follow-up compliance, completion and staff resources. Clinic variables (pain and fever), analytics (blood and urine) and image techniques (echography and radiography) were recorded at 10, 45 and 90 days in SFU and at 3 months in RFU. The SFU group received nutritional and analgesic recommendations. Preliminary clinical outcomes were compared and complications were recorded in each group.
RESULTS: The feasibility objectives were matched as follows: 94.1% of recruitment rate, 5.9% refused to participate, 10 patients/month were recruited, 93.1% of follow-up compliance and 90% of completion. No clinical differences were found between groups. There was a recurrence in the RFU group.
CONCLUSIONS: The feasibility objectives were matched except those related to human resources. Clinical outcomes did not favour any group or contraindicate the development of a future clinical trial.

The treatment of patients with chronic wounds is a multiprofessional challenge. Based on a comprehensive diagnosis and integrated into a causal treatment concept, patients should always be treated with a modern wound therapy. This wound therapy should try to take into account many different factors such as the wound healing phases, infection status, exudate levels, but also individual patient wishes. Especially in the case of chronic wounds of the lower extremities and edema, compression therapy is also very important for therapy and recurrence prophylaxis. In addition, the pain, which is usually very distressing, should be recorded and adequately treated or avoided. Modern moist wound therapy can then support the healing of patients with chronic wounds, reduce complications and thus improve their quality of life.
UNASSIGNED: Die Behandlung von Patienten mit chronischen Wunden stellt eine multiprofessionelle Herausforderung dar. Auf der Basis einer umfassenden Diagnostik und eingebunden in ein kausal ansetzendes Behandlungskonzept, sollte bei den Patienten auch immer eine moderne Wundtherapie durchgeführt werden. Diese Wundtherapie orientiert sich dabei an vielen verschiedenen Faktoren und sollte versuchen u. a. die Wundheilungsphasen, Infektionsstatus, Exsudatmengen, aber auch individuelle Wünsche der Patienten zu berücksichtigen. Insbesondere bei chronischen Wunden der unteren Extremitäten und Ödemen ist die Kompressionstherapie für die Therapie und Rezidivprophylaxe sehr wichtig. Zudem sollten die meist sehr belastenden Schmerzen erfasst und adäquat behandelt bzw. vermieden werden. Eine moderne feuchte Wundtherapie kann dann die Heilung von Patienten mit chronischen Wunden unterstützen, Komplikationen vermindern und somit die Lebensqualität verbessern.

Bacterial vaginosis (BV) is the most frequent vaginal infection worldwide. It is caused by the overgrowth of anaerobic vaginal pathogens such as Gardnerella spp. BV has been associated with the occurrence of dense multispecies biofilms on the vaginal mucosa. Treatment of biofilm-associated infections such as BV is challenging. In this study, we have tested the role of a quaternary ammonium compound, dequalinium chloride (DQC), in the eradication of Gardnerella spp. biofilms. The effects of the test substance on the biomass and the metabolic activity of the biofilm of Gardnerella spp. were assessed in vitro using a microtiter plate assay. In addition, the effect of DQC on the Gardnerella spp. biofilm was further assessed by using scanning electron microscopy and confocal laser scanning microscopy. The results showed that DQC was particularly effective in the destruction of BV-associated Gardnerella spp. biotypes, impacting both their biomass and metabolic activity. In addition, the disruption of biofilm architecture was evident and was probably caused by multiple mechanisms of action. We conclude that DQC is an antibiofilm agent and is able to efficiently destroy Gardnerella spp. BV-associated biofilms. Therefore, it is a valid option for BV therapy and has the potential to prevent BV recurrences.

BACKGROUND: The therapeutic effect of ultraviolet (UV) light is generally attributed to its immunosuppressive and immunomodulatory effects. Since chronic inflammation is the major factor in the development of nasal polyposis, we have previously used mixed ultraviolet-visible light (mUV-VIS, Rhinolight®) phototherapy for the treatment of nasal polyps.
OBJECTIVE: In the present open, multicenter study, our aim was to delineate whether mUV-VIS applied postoperatively in vivo together with intranasal steroid treatment could reduce the recurrence of nasal polyps.
METHODS: After functional endoscopic sinus surgery, one group of patients received mUV-VIS light together with standard intranasal steroid (mometason furoate 2 × 200 μg) application for a 12-week treatment period, whereas the other patient group obtained only intranasal steroid for the same duration. We recorded nasal endoscopy images and obtained demographical and clinical data, total nasal score (TNS), and nasal obstruction symptom evaluation (NOSE). We performed acoustic rhinometry and measured nasal inspiratory peak flow. Follow-up was 12 months.
RESULTS: We found that the recurrence of nasal polyps was significantly diminished, and based on video-endoscopic measurements, the size and grade of recurrent polyps were significantly smaller in the phototherapy-receiving group. Nasal obstruction values and NOSE were significantly better throughout the follow-up period in the mUV-VIS light-treated group than in the intranasal steroid monotreatment group.
CONCLUSIONS: Rhinophototherapy together with standard nasal steroid application may have a supportive role in the treatment of recurrent bilateral nasal polyps.

BACKGROUND: Smartphones and wearable devices can be used to obtain diverse daily log data related to circadian rhythms. For patients with mood disorders, giving feedback via a smartphone app with appropriate behavioral correction guides could play an important therapeutic role in the real world.
OBJECTIVE: We aimed to evaluate the effectiveness of a smartphone app named Circadian Rhythm for Mood (CRM), which was developed to prevent mood episodes based on a machine learning algorithm that uses passive digital phenotype data of circadian rhythm behaviors obtained with a wearable activity tracker. The feedback intervention for the CRM app consisted of a trend report of mood prediction, H-score feedback with behavioral guidance, and an alert system triggered when trending toward a high-risk state.
METHODS: In total, 73 patients with a major mood disorder were recruited and allocated in a nonrandomized fashion into 2 groups: the CRM group (14 patients) and the non-CRM group (59 patients). After the data qualification process, 10 subjects in the CRM group and 33 subjects in the non-CRM group were evaluated over 12 months. Both groups were treated in a similar manner. Patients took their usual medications, wore a wrist-worn activity tracker, and checked their eMoodChart daily. Patients in the CRM group were provided with daily feedback on their mood prediction and health scores based on the algorithm. For the CRM group, warning alerts were given when irregular life patterns were observed. However, these alerts were not given to patients in the non-CRM group. Every 3 months, mood episodes that had occurred in the previous 3 months were assessed based on the completed daily eMoodChart for both groups. The clinical course and prognosis, including mood episodes, were evaluated via face-to-face interviews based on the completed daily eMoodChart. For a 1-year prospective period, the number and duration of mood episodes were compared between the CRM and non-CRM groups using a generalized linear model.
RESULTS: The CRM group had 96.7% fewer total depressive episodes (n/year; exp β=0.033, P=.03), 99.5% shorter depressive episodes (total; exp β=0.005, P<.001), 96.1% shorter manic or hypomanic episodes (exp β=0.039, P<.001), 97.4% fewer total mood episodes (exp β=0.026, P=.008), and 98.9% shorter mood episodes (total; exp β=0.011, P<.001) than the non-CRM group. Positive changes in health behaviors due to the alerts and in wearable device adherence rates were observed in the CRM group.
CONCLUSIONS: The CRM app with a wearable activity tracker was found to be effective in preventing and reducing the recurrence of mood disorders, improving prognosis, and promoting better health behaviors. Patients appeared to develop a regular habit of using the CRM app.
