ABSTRACT

Objective: Breakthrough COVID-19 infections are common following immunisation with various types of vaccines. The patterns of infections have not been well established. We aimed to analyse the signs and symptoms of post vaccination infections in addition to the need for hospital admission, ER visit and supplemental oxygen in relation to age and gender. Methods: A cross-sectional cohort study was conducted in JUH from March 2021 to August 2022, we interviewed 1479 individuals who are >15 years of age and got a breakthrough infection. The statistical analysis was performed using STATA statistical software. Results: Out of the 1479 cases, 50.2 % and 69.4 % were females and less than 45 years of age respectively. Symptoms of cough, fever and headache were reported by nearly 50 % of the patients, while one-third complained of dyspnoea. We found that participants older than 45 years had worse clinical outcomes (P-value < 0.001). 13 deaths were identified in this study due to breakthrough infection, 92.3 % of them were older than 45 years (P-value < 0.001). Participants ≥45 years who experienced a breakthrough infection of COVID-19 were 0.7 times less likely to be females using adjusted logistic regression. Conclusion: This study indicates that despite more severe symptoms reported in younger patients, the major clinical outcomes were worse among older patients, which makes age a major risk for poor outcomes regardless of symptoms. Thus, older people should be evaluated carefully when presenting with mild symptoms of COVID-19 breakthrough infection. The study also confirms that there is no difference in the incidence of COVID-19 breakthrough infections between males and females. Prospective studies are needed to risk stratify COVID-19 breakthrough infections, which should take into account variants of the virus and comorbidities.

ABSTRACT

Metformin is a widely used antidiabetic biguanide. Retrospective data demonstrated the association of metformin use with survival benefit in multiple tumor types. Interest in repurposing metformin to treat cancer has not been translated into encouraging clinical benefit. In animal models, metformin activated cytotoxic T cells and exerted an immune-mediated anticancer effect. The current research was conducted to investigate the possible therapeutic benefit of metformin in combination with metronomic cyclophosphamide in an experimental cancer model. Ehrlich ascites carcinoma was injected into the subcutaneous tissue to induce solid tumors in syngeneic mice. Exponential solid tumor growth ensued and was effectively arrested with the administration of a cytotoxic dose of parenteral cyclophosphamide. Alternatively, oral metformin and continuous, low-dose cyclophosphamide significantly inhibited tumor growth relative to untreated mice. The drug combination was well tolerated. Histopathological examination of the tumor showed an increased number of tumor-infiltrating lymphocytes and enhanced expression of granzyme B by this drug combination. The current data suggests a potential role of metformin and metronomic chemotherapy that warrants further investigation.

ABSTRACT

How we move our bodies affects how we perceive sound. For instance, we can explore an environment to seek out the source of a sound and we can use head movements to compensate for hearing loss. How we do this is not well understood because many auditory experiments are designed to limit head and body movements. To study the role of movement in hearing, we developed a behavioral task called sound-seeking that rewarded mice for tracking down an ongoing sound source. Over the course of learning, mice more efficiently navigated to the sound. We then asked how auditory behavior was affected by hearing loss induced by surgical removal of the malleus from the middle ear. An innate behavior, the auditory startle response, was abolished by bilateral hearing loss and unaffected by unilateral hearing loss. Similarly, performance on the sound-seeking task drastically declined after bilateral hearing loss and did not recover. In striking contrast, mice with unilateral hearing loss were only transiently impaired on sound-seeking; over a recovery period of about a week, they regained high levels of performance, increasingly reliant on a different spatial sampling strategy. Thus, even in the face of permanent unilateral damage to the peripheral auditory system, mice recover their ability to perform a naturalistic sound-seeking task. This paradigm provides an opportunity to examine how body movement enables better hearing and resilient adaptation to sensory deprivation.

ABSTRACT

Acceleration of glycolysis is a common trait of cancer. A key metabolite, lactate, is typically secreted from cancer cells because its accumulation is toxic. Here, we report that a viral oncogene, HTLV-1 bZIP factor (HBZ), bimodally upregulates TAp73 to promote lactate excretion from adult T-cell leukemia-lymphoma (ATL) cells. HBZ protein binds to EZH2 and reduces its occupancy of the TAp73 promoter. Meanwhile, HBZ RNA activates TAp73 transcription via the BATF3-IRF4 machinery. TAp73 upregulates the lactate transporters MCT1 and MCT4. Inactivation of TAp73 leads to intracellular accumulation of lactate, inducing cell death in ATL cells. Furthermore, TAp73 knockout diminishes the development of inflammation in HBZ-transgenic mice. An MCT1/4 inhibitor, syrosingopine, decreases the growth of ATL cells in vitro and in vivo. MCT1/4 expression is positively correlated with TAp73 in many cancers, and MCT1/4 upregulation is associated with dismal prognosis. Activation of the TAp73-MCT1/4 pathway could be a common mechanism contributing to cancer metabolism. SIGNIFICANCE: An antisense gene encoded in HTLV-1, HBZ, reprograms lactate metabolism and epigenetic modification by inducing TAp73 in virus-positive leukemic cells. A positive correlation between TAp73 and its target genes is also observed in many other cancer cells, suggesting that this is a common mechanism for cellular oncogenesis.

ABSTRACT

INTRODUCTION: Breast conservation is the standard of care for early breast cancer. Several oncoplastic approaches have been described for the reconstruction of partial breast defects. The multiplicity of techniques indicates that the ideal reconstructive technique is yet to be identified. There has been a recent emphasis on minimizing the magnitude of surgery. In this report, we describe our experience using the pectoralis major muscle to fill relatively large post-tumorectomy breast defects. PATIENTS AND TECHNIQUE: Nine patients were operated on for malignant breast lesions. Tumorectomy resection with surgical margin rendered a 40-50% breast defect. The parenchymal defect was repaired with an advancement muscle flap of the ipsilateral pectoralis major muscle. RESULTS: All patients experienced a non-eventful postoperative course. The early cosmetic outcome was excellent in four patients, good in another four, and fair in one patient. CONCLUSION: The pectoralis major flap is useful for local repair of upper half partial breast defects in non-ptosed, cup A-B breasts.

ABSTRACT

BACKGROUND: Hepatitis C virus (HCV) is a known risk factor for hepatocellular carcinoma. Several epidemiological studies have pointed out to an association of HCV infection with other extrahepatic malignancies. The role of chronic HCV in breast cancer causation is less clear. Egypt is an endemic area of HCV infection with resulting significant morbidity. The association between HCV status and breast cancer risk in Egyptian women is hitherto unknown. METHODS: A retrospective study was performed. The prevalence of anti-HCV seropositivity was estimated in a sample of women with a breast cancer diagnosis, retrieved from the hospital records, and was compared to the raw data of a population study in Egypt. Anti-HCV negative and positive patients were compared regarding the disease course and outcome. RESULTS: Retrospective analysis revealed a markedly high prevalence of anti-HCV seropositivity in young breast cancer patients. In patients younger than 45 years, 13.4% were anti-HCV positive. Seropositivity was 6-fold higher in these patients than in adult females of the same age without cancer diagnosis (P = .003). The biological type, tumor size, nodal status, and disease-free survival were not affected by the patients' HCV status. CONCLUSION: Young Egyptian breast cancer patients have a dramatically high prevalence of HCV seropositivity. Further population studies are strongly required to investigate the epidemiological association of these two significant health problems.

ABSTRACT

A second wave of new severe acute respiratory syndrome coronavirus 2 (Covid-19) cases is widely feared. In fact resurgence of cases has been clearly observed in several countries that had seen flattening of the epidemic curve. In general, relaxation of community control measures is almost always blamed for the resurgence of cases. In this letter, the author describes an immunological explanation for the double-peaked epidemic curve of new viral diseases including Covid-19. According to this hypothesis, a second wave of cases is due to the effective innate immunity in some of the population. These individuals may later develop clinical disease upon repeated exposure. This theory claims that a double-peaked pattern of new cases in a new viral epidemic is intrinsically determined by the pattern of pathogen interaction with the host. According to this hypothesis, relaxation of the community control measures is not responsible; at least in part, for resurgence of cases.

ABSTRACT

Metastatic bone disease is generally incurable and leads to pathological fractures, pain, hypercalcemia, spinal cord compression and decreased mobility. The skeleton is the major site of bone metastases from solid cancers, including breast and prostate carcinoma. Bone metastasis is facilitated by activation of bone-resorbing osteoclasts, terminally differentiated multinucleated cells formed by fusion from monocytic precursors. Cancer cells are known to produce specific factors that stimulate osteoclast differentiation and function. Of interest, cancer cells are also known to alter their own bioenergetics increasing the use of glycolysis for their survival and function. Such change in energy utilization by cancer cells would result in altered levels of cell-permeable metabolites, including glucose, lactate, and pyruvate. Osteoclast resorption is energy-expensive, and we have previously demonstrated that during differentiation osteoclasts actively adapt to their bioenergetics microenvironment. We hypothesize that altered bioenergetics state of cancer cells will also modify the bioenergetics substrate availability for the tissue-resident bone cells, potentially creating a favorable milieu for pathological osteolysis. The goals of this review are to analyze how metastasizing cancer cells change the availability of energy substrates in bone microenvironment; and to assess how the altered bioenergetics may affect osteoclast differentiation and activity.

ABSTRACT

BACKGROUND: Hashimoto thyroiditis (HT) is an autoimmune lymphocytic thyroiditis and is the most common form of thyroid inflammatory diseases. The association of HT with papillary thyroid carcinoma (PTC) has been described. PTC is the most common form of malignancy associated with HT. When papillary carcinoma develops on top of Hashimoto thyroiditis, the disease tends to be less aggressive and lymph node and extra-thyroidal invasion are infrequent. RESULTS: We retrospectively examined the pathological features of our patients who were diagnosed with concomitant HT and thyroid cancer. In Egyptian patients, PTC was the main type of malignancy associated with HT (96.2%) and was often multifocal (46.2%). In contrast to the published literature, lymph node invasion and extra-thyroidal extension were as frequent in association with HT as in other cancer cohorts. We also observed the frequent occurrence of Hürthle cell metaplasia (23.1%) and the appreciable incidence of aggressive histological types of PTC (32%). CONCLUSION: Thyroid carcinoma with HT may have some aggressive features in areas with endemic goiter background.

ABSTRACT

Oral isotretinoin is the most effective anti-acne drug with the strongest sebum-suppressive effect caused by sebocyte apoptosis. It has been hypothesized that upregulation of nuclear FoxO transcription factors and p53 mediate isotretinoin-induced sebocyte apoptosis in vivo. It is the aim of our study to analyse the distribution of the pro-apoptotic transcription factors FoxO1 and FoxO3 in the nuclear and cytoplasmic compartments of human sebocytes in vivo before and during isotretinoin treatment of acne patients. Immunohistochemical analysis of skin biopsies with antibodies distinguishing phosphorylated and non-phosphorylated human FoxO1 and FoxO3 proteins was performed before isotretinoin treatment, six weeks after initiation of isotretinoin therapy, and in acne-free control patients not treated with isotretinoin. Our in vivo study demonstrates a significant increase in the nucleo-cytoplasmic ratio of non-phosphorylated FoxO1 and FoxO3 during isotretinoin treatment of acne patients. Translational and presented experimental evidence indicates that upregulation of nuclear FoxO1 and FoxO3 proteins is involved in isotretinoin-induced pro-apoptotic signalling in sebocytes confirming the scientific hypothesis of isotretinoin-mediated upregulation of FoxO expression.

ABSTRACT

AIM: Pleomorphic adenoma is the most common benign tumor of the parotid gland and is classically treated with superficial or total parotidectomy. Less radical surgeries have been proposed to minimize the risk of facial nerve injury. The oncological safety of these procedures remains controversial. We conducted this study to evaluate the safety of superficial hemi-lobectomy (quadrantectomy). PATIENTS AND METHODS: Retrospective analysis was conducted on the paraffin sections of archived superficial parotidectomy specimens from 11 male and 6 female patients (median age 33 years). The microscopic extent of extra-capsular extension was determined on pathological revision. In addition, prospective evaluation of 12 quadrantectomy procedures (M/F = 7/5, median age = 36 years) compared to 24 radical surgeries (M = F, median age = 40 years) regarding temporary and persistent facial nerve dysfunction on routine clinical assessment and recurrence rate. RESULTS: On retrospective pathological revision, pleomorphic adenomata had a median microscopic spread of 3 mm beyond capsule in paraffin sections (SD = 3.6). On prospective analysis with a median follow-up of 33 months (range = 18-54 months), quadrantectomy had similar relative risk of temporary facial nerve dysfunction evaluated at the immediate postoperative period as well as persistent nerve dysfunction assessed at 3 months (P = 0.701 and P = 0.902, respectively). Of the whole study population, one case of recurrence after total parotidectomy was observed at mid-term follow-up (P = 1.000). CONCLUSION: Parotid quadrantectomy is a safe management for smaller pleomorphic adenomata localized close to one of the two divisions of the facial nerve.

ABSTRACT

Osteoclasts are giant bone cells formed by fusion from monocytes and uniquely capable of a complete destruction of mineralized tissues. Previously, we have demonstrated that in energy-rich environment not only osteoclast fusion index (the number of nuclei each osteoclast contains), but also cytoplasm volume per single nucleus was increased. The goal of this study was to investigate the regulation of metabolic sensor mTOR during osteoclast differentiation in energy-rich environment simulated by addition of pyruvate. We have found that in the presence of pyruvate, the proportion of mTOR associated with raptor increased, while mTOR-rictor-mediated Akt phosphorylation decreased. Inhibition of mTOR with rapamycin (10 nM) significantly interfered with all aspects of osteoclastogenesis. However, rapamycin at 1 nM, which preferentially targets mTOR-raptor complex, was only effective in control cultures, while in the presence of pyruvate osteoclast fusion index was successfully increased. Inhibition of Akt drastically reduced osteoclast fusion, however in energy-rich environment, osteoclasts of comparable size were formed through increased cytoplasm growth. These data suggest that mTOR-rictor mediated Akt signaling regulates osteoclast fusion, while mTOR-raptor regulation of protein translation contributes to fusion-independent cytoplasm growth. We demonstrate that depending on the bioenergetics microenvironment osteoclastogenesis can adjust to occur through preferential multinucleation or through cell growth, implying that attaining large cell size is part of the osteoclast differentiation program.

ABSTRACT

OBJECTIVES: To study the incidence rate of lung cancer and its time trend in Basrah during 2005-2012. METHODS: This was a cancer registry-based retrospective study including all Basrah inhabitant patients diagnosed with primary lung cancer during the period from January 2005 to December 2012. The crude incidence rate was calculated in addition to the age standardized incidence rate (ASIR)/100,000 using the world standard population. Results: Out of 746 registered cases of lung cancer in Basrah, 75.9% were males and 24.1% were females with a male: female gender ratio of 3.1:1. The crude incidence rate was 3.93/100,000 (5.89/100,000 for males and 1.93/100,000 for females). The ASIR was 8.25/100,000 (13.30/100,000 for males and 4.08/100,000 for females). The time trend showed a decrease in incidence rate in the last 2 years (2011 and 2012) compared with the preceding years. CONCLUSION: The incidence rate of lung cancer in Basrah did not differ greatly from that reported for some Arab and neighboring countries. No definite time trend could be identified apart from a tendency for the incidence rate to decline in 2011 and 2012.

ABSTRACT

BACKGROUND: Although therapeutic mammoplasty (TM) was introduced for treatment of localized ductal carcinoma in situ and invasive breast carcinoma (stages I and II) in females with large breast size, the suitability of medial pedicle TM for treatment of breast tumors at different locations has not been established. The objective of this study was to assess the safety and esthetic outcome of medial pedicle TM for breast tumors at different locations. METHODS: The study was conducted from February 2012 to July 2014. Consecutive patients with early breast carcinoma with medium- and large-sized breasts, with or without ptosis, who were offered medial pedicle TM were included in the study. Patients who were not candidates for breast-conserving surgery or those with tumors located along the medial pedicle were excluded. All patients received immediate postoperative adjuvant chemoradiotherapy. RESULTS: Thirty patients with a mean age of 48.5 years received medial pedicle TM in the breast harboring the tumor or, additionally, the other breast (N=14). The tumors were in the upper (60.0%), lower (26.7%), and lateral (13.3%) quadrants. Minor complications occurred in five cases (5/30, 16.7%) in the ipsilateral and in two (2/14, 14.3%) contralateral breasts. No wound dehiscence or areolar necrosis was recorded. A total of 22 (73.3%) patients were scored as excellent cosmesis. After a median follow-up of 20 months, no locoregional recurrence or distant metastases were observed. CONCLUSION: TM using a medial pedicle is a safe and appealing technique among women with tumors at different locations.

ABSTRACT

BACKGROUND: Squamous cell carcinoma (SCC) is a fairly common tumor of the oral cavity. This tumor may affect any part of the mucosa of the oral cavity especially the tongue, the floor of the mouth and lips. The encountered intra-oral defects after tumor resection are often large and require climbing up the reconstruction ladder to more complex reconstructive options for accepted functional and cosmetic results to be achieved. However, most of the patients are old with medical co-morbidities requiring fast, simple, less morbid reconstructive option such as local flaps. The myocutaneous submental island flap has emerged as a simple and fast reconstructive technique that provides thin, pliable tissue with adequate volume and reliable blood supply. However, one major concern regarding the utility of the submental flap for repair of post-ablative tumor defects is the presumed interference with adequate lymph node neck dissection. METHODS: In this study, we present a cohort of thirty-six consecutive patients who were operated for oral SCC. All patients were offered submental island flap reconstruction of their resultant defects together with ipsilateral selective neck block dissection of levels I, II, III and IV; and the nodal yield of each level was tested pathologically. RESULTS: Nodal harvest was ≥ 12 in 88 % of the patients. Complications were encountered in two patients (5.5 %). CONCLUSION: Our data suggest that adequate cervical lymph nodes dissection, specifically level I and II cervical lymph nodes, can be fulfilled with concomitant submental island flap elevation.

ABSTRACT

INTRODUCTION: Pancreatic carcinoma affecting the uncinate process is a challenging surgical condition. Several considerations affect the management plan, including the need for vascular resection and the ability to achieve a clear margin. METHODS: The data of 19 patients who had curative resection for pancreatic adenocarcinoma of the uncinate process were reviewed. Operative mortality and morbidity, and disease-free survival (DFS) were calculated. RESULTS: The study population included 13 male and 6 female patients with a mean age of 55 years. Nine patients (47.4%) had stage I disease, seven patients (36.8%) had stage II disease, and three patients (15.8%) had stage III disease. A total of 12 patients had Whipple procedure and 7 patients had total pancreatectomy. In total, there were 9 R0 and 10 R1 resections. Operative mortality rate was 10.5% (2/19), postoperative leakage rate was 21.1% (4/19), and wound sepsis rate was 21.1%. Median DFS was 19.2 months. Survival was superior in the Whipple procedure group than in the total pancreatectomy group (median survival 19 months vs 4 months, respectively). Vascular resection and retroperitoneal safety margin status did not affect disease relapse. CONCLUSION: Non-metastatic pancreatic adenocarcinoma of the uncinate process should be offered R0 or R1 resection whenever technically feasible.

ABSTRACT

BACKGROUND: The aim of this study is to define an algorithm for the choice of reconstructive method for defects after laryngo-pharyngo-esophagectomy for hypopharyngeal carcinoma. METHODS: One hundred and forty two cases of hypopharyngeal carcinoma were included and operated on by either partial pharyngectomy, total pharyngectomy or esophagectomy. The reconstructive method was tailored according to the resected segment. RESULTS: Pectoralis flap was used in 48 cases, free jejunal flap in 28 cases, augmented colon bypass in 4 cases, gastric pull up in 32 cases and gastric tube in 30 cases. Mean hospital stay was 12 days. Mortality rate was 10.6% and morbidity rate was 31.7%. Total flap failure occurred in 3 cases of free flap and one case of pectoralis flap. There were 23 cases of early fistula. Late stricture occurred in 19 cases, being highest with myocutaneous flap (early fistula 12/50 and late stricture 13/50). CONCLUSION: Free jejunal flap was the flap of choice for reconstruction when the safety margin is still above the clavicle. In cases with added esophagectomy, we recommend gastric tube as a method of choice for reconstruction.

ABSTRACT

INTRODUCTION: Breast cancer is the most common cancer among Egyptian women. The disease is often advanced at diagnosis. Since molecular profiling is not feasible in routine practice, we sought to examine the association of age distribution with hormone receptor profile, disease stage and outcome among Egyptian women. PATIENTS AND METHODS: We conducted a retrospective review of breast cancer patients treated at Mansoura University Cancer Center in the Nile Delta from 2006 through 2011. Age groups were examined in relation to hormone receptors status and tumor clinicopathological criteria. Additionally, the effect of receptor status on disease relapse and disease-free survival was examined with logistic regression and Kaplan-Meier analysis. RESULTS: A total of 263 patients were included in the current analysis. About 66.9% (n = 176) of patients were hormone receptor positive, 14.1% (n = 37) were Her2/neu positive, and 19.0% (n = 50) were triple negative. Median age of the patients was 52 years and was equal across all receptor status types. Triple negative status correlated with increased risk of disease relapse (odds ratio = 1.8, P = 0.03) and with shortened disease-free survival (hazards ratio = 2.6, P < 0.01). CONCLUSION: The age distribution and receptor status pattern in the Nile Delta region does not explain the aggressive behavior of the disease. The age of the patients at diagnosis is older than patients in earlier studies from Egypt emphasizing the importance of implementing mammographic screening programs.

ABSTRACT

PURPOSE: The purpose of the study was to evaluate the activity and toxicity of cisplatin based chemotherapy in patients with advanced differentiated thyroid cancer refractory to radioactive iodine (I131). PATIENTS AND METHODS: We retrospectively reviewed the records of 20 patients with advanced thyroid cancer treated with cyclophosphamide 500 mg/m(2) on day 1, doxorubicin 50 mg/m(2) day 1 and cisplatin 50 mg/m(2) day 1 of a 21 days cycle community-acquired pneumonia (CAP) or the same regimens without cyclophosphamide adriamycin and Platinum (AP). RESULTS: Median age of patients was 65 years (range 54-80). The majority of patients had lung metastases (60%). 4 (20%) patients achieved a partial response. Stable disease was achieved in 6 (30%) patients. Overall clinical response was 50%. Mean follow-up time was 8 months (range 4-17). Mean progression free survival was 6 months (range 3-12). Mean overall survival was 9 months (range 4-17). Patients with partial remission had a mean time to disease progression of 9 months. 4 (20%) patients had Grade 3 or 4 neutropenia. One patient had febrile neutropenia. Mild neuropathy was recorded in 5 (25%) of patients. There were no treatment related deaths. CONCLUSION: The combination of CAP is active in the treatment of advanced thyroid cancer with tolerable toxicity. This regimen may still be used in patients who could not be treated with targeted therapy or combined with antiangiogenic drugs in future studies.

ABSTRACT

INTRODUCTION: Oncoplastic surgery is an integral part of current surgical treatment of breast cancer. Superior breast quadrant is a forgiving tumor location that often allows the conservation of the breast with simple mammoplastic manoeuvres. In this report, we describe a novel modification of the classic level I mammoplasty. PRESENTATION OF CASE: A 49 years patient had an ill-defined carcinoma at the 12 o'clock position that necessitated a generous tumorectomy. A diamond shaped incision was done over the tumor area and the nipple-areola complex. Peri-areolar skin was de-epithelialized and the tumorectomy was completed down to the pectoral plane. The incision was closed in a star-like shape around the areola leading to natural appearance of the breast and a limited visible suture line.
